WHAT THE HAY YOU WERE THINKING BY GIVING THAT THING TO PINKIE PIE?!!

WHAT THE HAY YOU WERE THINKING BY GIVING THAT THING TO PINKIE PIE?!!

Pinkie started trembling as she looked at the device attached at her hoof. Everypony started to move backwards, waiting for the inevitable storm. Then she started to scream in glee and started to run around in circles as she started to sign.

“I have the Ultimatrix, I have the Ultimatrix, I have the Ultimatrix!”

“Ehem, Pinkie Pie…” tried to intervene Princess Celestia, but Pinkie Pie was too excited to listen to anypony as she was too busy running around town as she was shouting ‘I have the Ultimatrix’ like crazy.

Then suddenly Pinkie Pie stopped running as the Ben 10 Omniverse theme started out of nowhere, as Pinkie started to sign:

Pinkie! She’s a pony and she wants to have fun,
But when you need a superhero, she gets the job done.

Pinkie! With a device that she wears on her hoof,
She can change her shape and save the world form harm.

When trouble’s taking place,
She gets right in it face! Pinkie!

When she lives are on the line,
It’s hero time! Pinkie!

“Where the hell is that music coming from?” asked Rex Salazar, confused.

“Let’s focus on the important thing.” said Rainbow Dash flying to Rex and taking him by the jacket, as she started to shake him violently. “WHAT THE HAY YOU WERE THINKING BY GIVING THAT THING TO PINKIE PIE?!!”

“Hey! Take it easy, amiga. I had no idea that Tennyson put his monster watch on the packages! He just told me to give it to Pinkie Pie, and that there was no time to explain.”

Princess Celestia put a hoof on Rainbow’s shoulder. “Rex Salazar is right, Rainbow Dash. But don’t worry, I’ll have a very serious talk with Ben Tennyson next time I see him,”

In the meantime, Pinkie have stopped singing and now she was examining the alien catalogue trying to figure out who to chouse first. Fearing the worse, Princess Celestia stopped her right before she could activate her first transformation.

“Pinkie Pie, wait!”

“What’s the matter Princess Celestia? You don’t want me to use the Ultimatrix? But I haven’t used it a single time! Is not fair, is not fair!”

Princess Celestia sighed as she tried to gather some patience. In her long life she haven’t met somepony as interesting as Pinkie Pie, and she had to admit to herself that it was a very interesting experience. But not always in a good way.

“It’s alright Pinkie Pie. Something tells me that you won’t listen to me if I forbid you to use it. All I ask is that you don’t use Discord’s transformation. That’s an order, you can use all of these creatures except for Discord.”

“Okey-Dokey-Lokey!” said Pinkie selecting an alien and pressing the button.

A green flash of light later, Pinkie have transformed into a tiny white anthropomorphic creature with blue eyes. Echo-Echo, as Ben called it.

Giggling like crazy, the little thing divided into several copies of herself.

“A’ have a bad feelin’ about this!” said Applejack.

Everypony went to cover themselves.

“SHOUTING CONTEST!” said one of the Pinkie Echo-Echos and the copies cheered in excitement.

The three of them made a circle and started to use their powers among each other making everypony to duck and cover their ears. Rex went as far as using his mechanized hands in a desperate attempt to block the sound.

“PINKIE STOP! FOR CELESTIA’S SAKE JUST STOP!” begged Twilight trying Pinkie to listen to her over the scandal.

“Sorry!” said Pinkie Echo-Echo, making her copies to disappear and then it pressed the Ultimatrix logo one more time, transforming again.

This time she transformed into a pink goo monster with blue eyes. “Oh this is so great! Look girls, I am a slime monster. Everypony fear Pinkie Pie!”

Rarity gasped and ran to hide to one of the kiosks to protect herself from getting dirty, as the confusion around grew by the second.

“Seriously, I hope that Princess Celestia gives Ben a very serious talk when he gets rescue and he comes back to get his stupid watch!” complained the white unicorn.

Then Pinkie Pie turned back to normal, looking uncharacteristically serious.

“You’re right! Ben is in danger! Who knows which horrible things he is facing now! And not that he doesn’t have his watch he may be in real danger! What would happen when the evil Vilgax gets him? Do you think he would survive? How do you plan to get back to him, Rex?”

The boy smiled at Pinkie calmly. “No worries amiga, I have everything under control! The dimensional weapon Ben used to get me here has a time effect. When 12 hours pass, I’ll go back to the Null Void to help my friend. He and his friends can handle things on their own, and when I go back Vilgax would have no chance!”

“That’s good and all Rex Salazar, but how do you think you would rescue Ben Tennyson?” asked Princess Celestia, visibly worried.

Rex thought about it and shrugged.

“Honestly, I have no idea! I always improvise and I know Ben does the same so I think we’ll be fine!”

Pinkie jumped over Rex at the time she transformed into an anthropomorphic tigress with sharp claws at her wrists. “Now you let me tell you something Rex Salazar! There’s nothing more important than friends and family and I would not let you go after Ben when if you’re just going to ‘improvise’. What you are going to do is to make a good plan, and I will go with you to save Ben!”

Then she turned back to normal.

“Wow, this one had a really bad mood!” said Pinkie. “But seriously Rex, you cannot jump to a dangerous situation just like that. We must think about something if we want to rescue Ben.!

“Why on earth you want to come with me? I’ve seen the Null Void and I can assure you that is not chido! I’ve also seen Vilgax army, they have laser weapons, robots, and all sort of dangerous things. Unlike you I’m used to that stuff!”

Pinkie Pie stood her ground. “I have to go, Rex. Why would Ben trust me the Ultimatrix if he didn’t want me to rescue him? He wants my help; this is his way to tell me!”

“Hey, amiga, I’ve seen the Chtulu impersonator, and I can tell why Ben is so eager to keep his watch away from him. And the last place he would look for the watch is here in ponyland! Your mission is to keep it safe!”

Pinkie Pie glared at Rex. “I’ll go either if you want it or not, Rex Salazar!”

She then turned to her friends.

“You guys are with me, right? We owe it to Ben after he saved us from the meanie pants of Discord!”

Twilight seemed worried. “Are you sure Pinkie Pie? Rex is right, we are not used to the type of menaces Ben and Rex deal with on their own worlds. Also, Rex has a point. Ben may have given you the Ultimatrix to keep it safe from Vilgax. You can’t just go and practically give it to him!”

But Rainbow Dash just nodded with a smirk. “I’m in! An adventure in another adventure? Why the hay not?”

Fluttershy agreed. “Ben is a good boy and a good friend. I think I’ll go too!”

Applejack sighed but nodded as well.

“We don’t have an option right, partner? A’ll join ya’ too!”

Rarity shrugged and smiled at Pinkie

“Okay darling, I’ll join you too just because Ben saved the last time. And also, now that he is not wearing that ugly thing, I may convince him to switch to something more elegant.”

Twilight groaned defeated and joined her friends who smiled at Rex. The bluish colt just looked at the girls and finally he sighed and nodded.

“Alright! But stay close to me all the time!” He looked at his watch. “I’ll be pulled back to the Null Void in about eight hours.”

The Princess looked at the six Bearers, proud, and then casted a quick spell on them.

“The magic of friendship can be so powerful that it can overcome parallel worlds and timelines! Please, make sure Ben Tennyson is safe and please give him back his watch as soon as possible! I don’t like that thing being in Equestria. I’ve also casted a spell on you, so your form doesn’t change when you cross the border across worlds. That way you would feel more comfortable!”

“Thank you, Princess Celestia!” said the six ponies.

Pinkie smiled. “Yes, I was afraid that Ben wouldn’t recognize me if I become a hairless monkey like him but now I don’t have to worry about the little things anymore!”

“Pinkie, darling, don’t take me wrong but your personality is too unique no matter how you look.” said Rarity.

The others nod in agreement, but Rex was only worried about what would happen next. “Ni modo! We are together in this but please be extra careful! In the end we’ll save Ben no matter what.”

“For Ben!” shouted the rest of the ponies.

Princess Celestia smiled at them and looked at the clock tower.

“Very well my little ponies, we’ll continue this conversation when the right time comes. I have to attend the celebration and this conversation took longer than expected so I better go now. Pinkie Pie, I wish you good luck in your mission to rescue your adoptive nephew. Just remember not to use Discord’s transformation and give that thing to Ben as soon as you see him!!”

With that she flew to the townhall where she would continue to rehearse her speech for the summer celebration after she raise the sun.

“I mean, I agree that Tennyson’s watch is dangerous, but why is she so eager to get that thing out of Equestria?” asked Rex.

“I guess she doesn’t forget the fact that there was a piece of technology that proved to be better than her magic!” said Twilight with a chuckle.

Pinkie Pie giggled.

“Okay girls, the dramatic pause is over now let’s keep enjoying the celebration! We have eight hours before we go to rescue so now it’s time to have some fun!”

Rex smirked. “Now we’re talking! What do we do first?”

Author's Note

So, this is a short introductory chapter for what’s about to come. The story would take place on the Null Void at Vilgax’s ship.

Also, sometimes Pinkie’s transformation would vary from Ben’s in color. Anyway.

Read ya’ later!

A party is always the answer!

A party is always the answer!

The festival started good and everypony was having lots of fun. But it soon turned into pure chaos. Ponies were running all over from the ‘horrible monsters’ who were competing against each other in the target shooting kiosk. A monster made of pink crystals who shot sharp crystal chunks; and a gray bluish colt who transformed his left forehoof into some sort of cannon that took chunks of the ground and then shoot them at the targets.

The scandal finally got into Princess Celestia’s nerves and she had no choice but fly to the middle of the town and calm everypony down with her Canterlot voice.

“ATTENTION EVERYPONY, CALM DOWN IMMEDIATELLLY!”

Ponies managed to calm down but just a little, as Pinkie in her petrosapien form (Diamondhead) kept playing on the background. Celestia had to gather every ounce of patience she had just to not to shout at the two of them to keep it quiet.

“I promise you these two creatures does not represent a threat! The crystal monster is no other than Pinkie Pie, Element of Laughter. She volunteered to try a shapeshifting spell for me. There’s nothing to fear, this is only an experiment to protect Equestria for future threats.”

With that, the panic finally stopped.

“The other pony is another volunteer to try a different approach to the same spell, he is just a colt who answers to me! There’s nothing to worry about, please keep celebrating.”

The ponies let escape a collective sigh and resumed the festivities.

Celestia rubbed her forehead with her wing as Twilight approached her.

“Princess Celestia, thank you for calming everypony down. But do you think it was okay to lie to everypony?”

“I challenge you to explain what’s really going on without making them to freaking them out again, Twilight Sparkle! Anyway, please remind me about this when I have a serious conversation with Ben Tennyson.”

Twilight took note for that, as Pinkie and Ben finished their competition by turning back to normal and look a new kiosk to try their powers when the other Bearers joined them.

“Darling, can I ask you something?” asked Rarity.

“Sure, what is it?” asked Ben with a smile.

“So, there are aliens on your dimension too? Are you an alien or half alien or something?”

Rex smiled. “Well, no. There are no aliens on my world. I still don’t understand how it all started, but as far as I understand my parents were scientists trying to find a cure for all diseases through the Nanites. Machines the size of a cell designed to repair any damage inside the human body. But something went wrong, and there was a huge explosion releasing the Nanites in the world. They turned people into mutants, called EVOs. I can control my Nanites at will and that’s how I create my machines.”

“Interesting!” said Applejack.

Rex smiled proudly. “Not only I can control my own Nanites, but other EVOs’ too, so I’ve cured a lot of them. I am the cure and Providence’s most valuable treasure!”

Ponies gasped, making Rex smile. He loved being the center of attention.

Celestia approached to the group. “That’s very noble Rex Salazar, but I will really appreciate if you try to control yourself here on my Kingdom. You’ve caused a huge scandal with your arrival. And the same goes to you, Pinkie Pie. Remember that you have an important mission to accomplish, so please save your and the Ultimatrix’s energy so you can face this ‘Vilgax’ and his army. We don’t know the dangers of Rex’s and Ben’s worlds so we better take every possible precaution.”

Rex’s confident smile faded. “You are right, and to be honest, you’re better off not knowing. But don’t worry, I’ll make sure to take them back in once piece, along with good old Ben.”

“I’m happy to hear that, Rex Salazar! But it is almost time for me to raise the sun so please get some sleep, so you are ready to save Ben.”

The ponies and Rex bowed and nodded. Especially Rex who hadn’t been able to rest since Breach sent him to the Null Void.

The summer celebration went without a problem, and Celestia raised the sun successfully making eveypony cheered for her. Rex even shouted, ‘Eres chida, Princesa’, but after everything was said and done it was time for them to go to sleep. Even if Pinkie kept insisting, they have a welcome party for Rex.

“Come on girls, just a quick party to welcome Rex to Equestria. He is leaving tomorrow, and he would not be able to participate in my famous parties like my nephew Ben!”

Twilight sighed. “Pinkie Pie, Princess Celestia clearly said that we need some sleep so we are ready to rescue Ben!”

“She’s right!” agreed Rex. “Mira amiga, I had a really long and exhausting day, and I could use some sleep. Seriously, you don’t know what’s expecting us in the Null Void. We would need to be as rested as possible to help Tennyson!”

“But a party is always the answer to recover all your strength after an exhausting day!” said Pinkie Pie, pouting.

Applejack was the one who got with the solution. “Pinkie Pie, think about it! Why would ya’ do a small party now when ya’ can make a huge party after we rescue Ben? Imagine how happy he’ll get when he comes back here! Ya’ always make the best parties, right partner?

Pinkie considered half of a second and then she smiled widely. “Of course! Thank you, Applejack! How I didn’t think about it first? of course, let’s rest and then save Ben so we can party later.”

Said that, Pinkie ran over to her bed.

“Great! Applejack you doomed us all!” complained Rainbow Dash.

“Come on, is not that bad. Is either this or going to battle burned out!” argued the cowgirl. “Ah’ don’t want to imagine what would happen at the Null Void.”

“Because of Vilgax’s army?” asked Fluttershy.

“Nope, because that thingy’ is still on Pinkie Pie’s hoof!”

…

At the next day, everypony gathered at the depths of Sweet Apple Acres so they could across worlds far away from indiscreet looks. Celestia have asked them to be as secretive as possible to prevent them to cause mass panic like the last night. Princess Celestia even slept at Ponyville so she could go to say goodbye to the six friends plus one and wish them good luck. But when she arrived, she noticed that Rex and Pinkie Pie were missing.

“Seriously, if they went ahead without us, they’re going to answer to me!” said Rainbow Dash angrily.

“Pinkie Pie wouldn’t do something like that!” said Twilight.

The others agreed, when finally, they saw Rex and Pinkie dragging a cart full of cupcakes.

Applejack raised an eyebrow. “Are ya’ actually plannin’ to get that thing with ya’ Pinkie Pie?”

Pinkie smiled.

“Well, duh! My favorite honorary nephew has been away for a very long time, and I want to make sure he’s been eating well so I woke up early and made lots of cupcakes for him and his friends. And us if we get hungry during the mission!”

“I don’t think that would be a good idea Pinkie Pie…” said Fluttershy softly, but Pinkie was determined to take the cupcakes with them.

They were about to say something when a red glow surrounded Rex.

“Hey it’s time!” said Rex.

Pinkie Pie hurried to put her hoof over Rex’s back as she put another hoof on the cart. Applejack put her hoof on Rex’s back too and offered her hoof to Twilight. Twilight gave a hoof to Fluttershy who then gave her hoof to Rarity, and finally Rarity grabbed Rainbow Dash’s hoof.

The seven ponies disappeared from the face of Equestria as Princess Celestia watched them leave.

“Good luck, my little ponies.”

“I’ll give you one last chance, Tennyson!” said Vilgax to Ben, who was immobilized in a metallic stretcher with special restraints. “Tell me where you sent the Ulitmatrix and your death would be less painful!”

Ben didn’t say anything, and gave Vilgax a smirk instead. This infuriated the conqueror of a thousand worlds and grabbed Ben by the collar of his t-shirt. But then, the whole ship shacked as it has been hit.

“What?!”

Vilgax looked through the window only to see one of the ships from his fleet had gone crazy and it was spinning all over and shooting randomly all over; making Ben laugh when he saw it.

“What’s so funny, Tennyson?” shouted Vilgax.

“She’s here! I knew she would do the opposite to what I told her, after all I lived with her for about a week. You’re doomed Vilgax, you haven’t met anyone like her. You’re going to be out of strength and out of patience in less than five minutes. Especially now that she has the Ultimatrix.”

The ship where the girls and Rex have appeared was still spinning around and shooting missiles and lasers randomly damaging the other ships on Vilgax’s fleet as Pinkie was happily with the ship controls making her friends being send from one side to another.

Pinkie Pie giggled. “This is really fun! I wonder what this lever does…”

Pinkie pushed the lever, and the ship moved forward crashing into smaller ships destroying them instantly.

“Pinkie, stop it for Faust’s sake!” begged Twilight.

Pinkie released the controls as nothing happened. “Okey-dokey-lokey!”

The door of the control room suddenly opened, and several golden robots with black claws and legs, and black heads with red eyes broke into the room shooting everything that moved.

Twilight reacted just in time and she created a force-field with her magic to protect her and her friends.

“This is why Ben didn’t want you involved!” said Rex coming out of the forcefield and destroying the robots with his mechanical tentacle, one of his most powerful machines courtesy of the Omega Nanite. But no matter how many robots he destroyed, more of them came.

“Huh… a little help!” begged Rex.

In the meantime, Pinkie was mesmerized by the lasers flying over and impacting against Twilight’s forcefield.

“Huh… this is so cool! Do you think I can borrow these things? I can only imagine the possibilities for parties with these!”

Pinkie Pie was giggling imagining what would happen, smiling in her little world. Seeing that they could not count on her for a while Applejack jumped out of the forcefield with her lasso that she used to tie up several robots who kept coming. Rainbow also came to action and flew around the robots making them to go in circles and forcing them to destroy among them.

In the meantime, the forcefield finally started to crack and one of the lasers finally destroyed the forcefield and the cart full of cupcakes. Pinkie could only look in shock.

“Hey! I worked really hard baking that for my favorite nephew in the whoooole multiverse! No pony gets in the way with my presents and my family and friends!”

Said that Pinkie checked on the watch and transformed into a giant pink insect who started to spit some sort of pink aced saliva that made the robots to melt at its contact. She kept flying in circles spitting the goo to the robots.

“Good move!” congratulated Rex as he removed the remaining of Vilgax’s forces.

“Remind me never mess with Pinkie’s cooking!” said Rainbow Dash, still surprised by her friend’s reaction to her cupcakes being destroyed.

The others nodded, but it they didn’t have the time to think since the ship started to move as it was dragged to Vilgax’s main ship by a powerful beam. Rex rushed to the controls and tried to move away from the beam but it was stronger than the motors.

“Great, we are getting dragged to Vilgax himself!” announced Rex.

“WHAT?!!” shouted Rarity.

Twilight frowned. “With the scandal we made, I’m not surprised!”

Rex nodded. “Let’s look at the bright side. We are getting right to where Teenyson is! Now we just have to think what we would do as soon as they get inside or we’ll be in verdaderos problemas!”

Pinkie smiled turning back to normal, and then pulled out an emergency party kit out of nowhere and started to decorate the place.

“What are you doing Pinkie Pie?” asked Fluttershy.

Pinkie simply winked an eye to her.

“I’m throwing a party, silly! Rex said we have to think what we would do when Vilgax’s army goes into the ship, and a party is always the party! I am sure that Vilgax would be so delighted by the party I’m throwing on his honor that he would release my nephew and his friends. And he would have such a good time that he would not want to do anything bad anymore!”

…

Vilgax lead his army ready to be the first one to board the ship and take the creature who had the Ultimatrix. At his sign the gates of the captured ship. He dragged his large sword ready to attack; but before he could do anything, a pink horse appeared right before him with a confetti cannon and a blowout jumping over his chest making him fall out of impression. Then Pinkie hurried and put a party hat on his head, and a glass of pink punch and apiece of cake on each of his hands.

“Welcome to your party dear mister Vilgax! Come on in! I’ve prepared lots of games just for you so let’s have fun, alright?!”

And once again, before he would be able to react, Vilgax was showered by balloons and streamers all over him.

“The fun is barely starting! Please come on in and let’s play some games!”

Vilgax roared in anger and he jumped over Pinkie Pie. Pinkie simply made some graceful backflips at the time she turned into a big pink crab with a gigantic head and blue eyes, who started to dance some sort of claque using its pincers as castanets.

Vilgax recovered from the shock and walked toward the creature who held the Ultimatrix, only to realize he walked into a dance floor. A disco ball came out from the roof at the time loud music started playing, making Pinkie Pie’s cerebrocrustacean form to dance faster. Vilgax tried to put his hands over the creature, but Pinkie only saw that as he wanted to dance and kept dancing around making Vilgax fall over and over again as his robots only watched at the scene completely confused of what was going on.

And before they could help their master, they were smashed by Rex’s mechanical hands.

“The way is clear Miss Pinkie Pie! Time to start this fiesta!”

Pinkie giggled and transformed into the alien who could run fast, the one Ben named XLR8. But unlike Ben’s, Pinkie’s transformation had a pink body and blue eyes.

“Tag, you’re it!” she said to Vilgax as she started to run as fast as she could, with her friends following.

Vilgax roared in anger.

“DESTROY THE MULTI-COLORED HORSES! NO SURVIVORS! But spare the pink one, THE PINK PEST IS MINE!”

Author's Note

And the battle begins! Could Vilgax stand Pinkie Pie? Stay tunned to see what’s next.

Read ya’ later!

Hurry up, dear Mister Vilgax! Or we would arrive to our next game!

Hurry up, dear Mister Vilgax! Or we would arrive to our next game!

“WHERE ARE YOU HIDING PINK PEST?!” shouted Vligax destroying every single door on his own ship with his enormous ship.

There had been only thirty minutes, and the Conqueror of a thousand worlds was at his wits end. In that short period of time he had been wrapped in streamers, his hands filled with candy and cake every time he turned around; and the worst part was that the pink pest who wore the Ultimatrix had spent the last thirty minutes treating him as he was his playmate. Vilgax found himself taking part in a silly game where he had no idea he was taking part of, over and over.

“I ASKED WHERE ARE YOU HIDING?!” shouted Vilgax so angry that his voice resounded all over the ship.

“I can’t tell you silly!” said a voice coming through the vents. “Otherwise, playing hide and seek would be too easy and therefore, boring! Whoopsie, I just ruined it! Hehehe!”

Vilgax looked up only to see the pink pest spying him through the vents with a huge smile. Grinding his teeth, Vilgax stabbed the vents with his sword, only to accidentally leave the room in complete darkness. He roared in anger. This was by far the most frustrating battle he had ever fight, including those against Tennyson. And to make things worse he heard the pink pest’s giggles from outside the room.

He ran after her, only to find her hanging from a lamp by her tail. “What do you think, dear mister Vilgax? I look like a cute little monkey! Oh, this reminds me of a game! We must play now!”

Said that she activated the Ultimatrix, turning into an arachnochimp, Spidermonkey, who happily threw a string of web to Vilgax’s eyes. The Conqueror of a thousand worlds screamed as Pinkie Pie Spidermonkey started to run away as she giggled as crazy. Vilgax tried to take her down by throwing random blows with his sword but Pinkie Pie dodged every single one of them, frustrating Vilgax more and more.

For the first time in many years, Vilgax was on the edge of tears.

In the meantime, Rex Salazar and Pinkie Pie’s five friends just looked at the scene not knowing what to think of it.

“Uf! In these circumstances I feel pity for the Cthulu impersonator!” said Rex.

The five ponies could only nod. As a matter of fact, Vilgax has lasted way more than any of them could. Pinkie was a very good friend and funny to be around, but when it comes to parties Pinkie Pie did not know the meaning of moderation.

In the meantime, Twilight was checking the ship’s blueprints they were able to get as Vilgax was busy ‘playing’ with Pinkie Pie; so they could get some information from the maintenance rooms.

“Okay, according to these blueprints, prisoners are held on sector C which should be a down this hallway.”

Rex nodded and activated his Smack-Hands to destroy every single robot on their way and finally force the door open. When they opened the door, Vilgax’s robots started to shoot at them, but Rex switched his giant robotic hands into smaller ones that generated a force field.

“Twilight!!” shouted Rex.

“On it!” said Twilight creating her own forcefield, allowing Rex to transform his block-party into his fun-chucks so he could destroy the robots to clear the way.

He made a high-five/high-hoof with Twilight.

“We make a great team!”

“We certainly do, Rex! Now let’s rescue Ben!”

Rex force-opened another door to finally get to Gwen, Kevin and Ben; trapped into metal stretches with restrains in their waists, wrists and ankles.

“Guys!” greeted Rex.

Kevin looked at him. “Hey Robot-boy! I hope you brought some reinforcements!”

Rex nodded as he reactivated his Smack hands and was about to free Kevin, but before they could warn him a powerful electric current ran over the three prisoners making them scream in pain.

“Qué demonios?!” asked Rex.

“Obviously it wouldn’t be that easy!” complained Kevin, glaring at Rex.

“Yes! They would electrocute us if you put the slightest pressure on them, we have to think about something else!” said Gwen.

But despite the pain, Ben was smiling confidently. “We will think about something soon enough, don’t worry. But more importantly, did you bring the reinforcements, Rex?”

Rex moved aside revealing the five ponies behind him.

“Howdy partner!” greeted Applejack.

“Ben! I’m so glad you’re okay!” said Fluttershy happily. “I am so sorry, you told Pinkie to keep the watch away but…”

Rainbow Dash nodded. “But you know Pinkie Pie and you know us; did you actually think we wouldn’t come to you rescue? Well think again kiddo!”

“And now that you gave that ugly accessory of yours to Pinkie Pie you may accept something more fashionable to wear. Just saying.!” joined Rarity.

Twilight didn’t say anything. Instead, she used her magic to open the restrains and release the three of them. Since Vilax’s security system had never faced pony magic, it was easy for her to free them.

“Thank you, girls!” said Ben as he stretched up. “How is Aunt Pinkie Pie? Has Vilgax gone nuts yet?”

A scream of anger resounded all over the ship.

“He’s about to!” said Rex.

“So, you knew we would come to rescue you, Ben?” asked Twilight.

Ben smiled at her. “Of course! I lived a week and a half as her nephew, I knew you would do anything for a friend. And I also knew that it is only a matter of time Vilgax runs out of patience, and he ends up burning himself out trying to calm her down.”

Kevin shook his head in disbelief. “What the hell is going on here? What are these creatures, Tennyson?”

“Yes Ben, we owe them for saving our lives, but I could use an explanation too!” added Gwen. “All you said was that you sent Rex for help. But can you give us more details?”

Ben sighed and began explaining. “You see, six months ago Paradox sent me to another dimension ruled by colorful equines. Even I turned into a pony while I was there!”

Kevin started laughing, but Gwen shut him up with poking him with her elbow.

“Kevin!”

“I’m sorry, but the mere idea of Tennyson becoming a pony is just hilarious!”

Ben rolled his eyes in annoyance but continued his story. “Paradox put me under the care of a girl called Pinkie Pie. She is a happy-go-lucky girl but is kinda crazy. In a good way! She is always looking after the ponies she care about, and she immediately adopted as her honorary nephew. And also tried to make every single minute I spent in Ponyville an unforgettable experience. She didn’t even let me sleep at some times because we were having so much fun, but it was mostly a good experience.”

Rainbow Dash agreed with Ben. “Pinkie Pie is very especial at her own way, but why on Equestria you trusted her your ‘monster watch’?”

Gwen and Kevin turned to Ben.

“That’s true, why did you give that girl the Ultimatrix?”

But then the whole ship shacked, followed by Vilgax’s screams of desperation, making Ben giggle.

“To be honest, I was really scared when Vilgax surrounded us and I though everything was lost. But then I reminded of Ponyville and how Paradox told me the magic of friendship would help me to save the universe one day. So I knew it was time.”

“I see!” said Twilight. “You trusted us because of the Magic of Friendship! It seems that Princess Celestia was right, the Magic of Friendship is so great that can overcome any distance, including alternate dimensions.”

The other ponies joined with a huge smile, but Kevin and Rex had to make a monumental effort to not burst into laughter. But Gwen just find the whole thing sweet.

“Aww…”

An alarm started to ring all over the ship.

“The ship have received some critical damage! Vilgax must have overdone while chasing your adoptive aunt, Tennyson!” said Kevin, worried. “If we don’t move fast, this won’t end good for us. Where’s the dimensional weapon that you used to send Robot-bot away, Tennyson?”

Ben frowned. “Vilgax has it. We have to get him now!”

The three humans and ponies ran to where Vilgax and Pinkie were ‘fighting’.

…

Pinkie Pie was happily skipping around in her gourmand form (Upchuck), who like all other of the Pinkie’s transformation, was bright pink with blue eyes. And apparently was not aware or didn’t care that the ship was about to explode.

“Hurry up, dear Mister Vilgax! Or we would arrive to our next game!”

Vilgax was running after her, but much slower than before. He was getting exhausted after all of those games and silly dances Pinkie managed to involve him into. Then, she stopped moving. Vilgax smirked, this was perfect! The Pink Pest was getting tired too!

Seeing his chance he jumped over her, only to realize he was on a ‘Twister’ mat. He looked around, only to see the Pink Pest in her normal form gigging.

“Right hand to red!”

Vilgax raised his right arm to squish the Pink Pest, but she slipped away just in time and ended up in the position the game indicated.

Pinkie Pie giggled and spined the wheel and announced:

“Left leg to yellow!”

Vilgax raised his claw once again, but Pinkie stopped him.

“Wait, Dear Mister Vilgax! I said left leg, and that’s your left hand…”

“Oh, you’re right… sorry!”

He obediently moved his leg to the right spot, when he just froze in realization.

“WHAT THE HELL IS WRONG WITH ME?!”

He ripped the mat into pieces as Pinkie Pie looked at him happily.

“Oh! Do you want to play another game, dear Mister Vilgax?” asked Pinkie Pie giggling.

Vilgax’s eye twitched when the rest of the ponies and his three prisoners joined the ‘party’.

“Aunt Pinkie Pie!” called Ben.

Pinkie turned to Ben, happily. “Oh, if it isn’t my favorite nephew in the whole universe! I’m so glad you’re okay! Ready to join the party? Dear Mister Vilgax is having so much fun that he would not do anything bad ever again, right Dear Mister Vilgax? Can I get you something else? A snack, maybe more ice cream, or cake… maybe a bunch of candy!”

Vilgax raised as tall as menacing as his hands was getting closer to the pistol on his belt, ready to finish that thing that was smiling at him so confidently. Her eyes lighted in joy as she got her hoof closer to the Ultimatrix. This wasn’t the first time they’ve done something like this on the thirty six minutes they had been ‘playing’, with Vilgax’s patience running out by the minute. He would shot her with the gun, but she would dodge it by some kind of miracle and then it would be the beginning of a new game. He could see it on Pinkie’s eyes: she was preparing the new game that would begin as soon as he fires his gun.

This was too much for him, Vilgax finally fell on his knees and started to cry.

“Stop, please just stop! I would do anything, Tennyson… just get that thing away from me! I’M BEGGING YOU!”

Gwen and Kevin were speechless.

“What kind of crazy world you went to, Tennyson?” asked Kevin.

Pinkie’s friends just looked at Vilgax with pity on their eyes. They knew that Pinkie Pie could be exasperating when it comes to have fun, but this was the first one they saw somepony broke down like this. This time Pinkie Pie really overdone herself.

“Please Tennyson!” begged Vilgax.

Ben nodded. “The dimensional weapon. Give it back!”

Vilgax did as he was told happy to get rid of that thing once and for all.

“Ben where are we going?” asked Gwen worried by looking at the state that Vilgax was.

Without giving them time to ask more questions, Ben activated the weapon to create a portal where everyone and everypony disappeared into, leaving Vilgax alone in the ship that was about to explode.

His robots found him and dragged him to an escape pod, where they gave them time to calm down. This was the first time they see their master in this state. Which kind of opponent could break him in so little time? What kind of monster did Ben Tennyson befriended?

…

In Canterlot, the two Royal Sisters were having some tea and enjoying the afternoon.

“Is something on your mind, sister?” asked Princess Luna.

“Yes, about that thing I told you about in the morning. I’m just worried about the Elements, and Ben Tennyson Pie of course.”

“The young hero who defeated Discord?” asked Luna. “Yes, I am worried about his safety too. But I know the girls can do anything. Hopefully we would see them and young Tennyson healthy and safe!”

“We still don’t know which kinds of dangers they would face in the other world, right?” said Princess Luna.

Princess Celestia nodded. “You may be right, but they also have Rex Salazar on their side. Besides, Ben Tennyson haven’t faced an enemy like Discord before and he managed to defeat him, so I have faith on them!”

Luna nodded, when out of nowhere a red portal appeared over them. The sisters quickly moved a way to a safe distance right at time a large group of ponies came from above them. Rainbow Dash and Fluttershy used their wings to break the fall and managed to catch Applejack and Rarity. Twilight used a spell to fall slow, but Rex used his mechanized legs that destroyed the table where the sisters were having tea and caught Gwen. Pinkie transformed into Jet-Ray and caught Ben, but Kevin crashed to the floor.

“God damn it!” complained Kevin, who have transformed into dark gray pony with black hair and mane and a Cutie Mark that represented his car. “Great! Where did we end up, Tennyson?”

“Huh, it seems we’re back in Equestria!” said Pinkie turning back to normal. “Hiya Princess! How are you?”

Both Princesses were looking at the scene speechless, as Gwen stood up as she looked at her new body. She has transformed into a pink unicorn with orange mane and tail, and a book Cutie Mark. She looked around.

“Okay… this doesn’t seem like the Plumbers’ headquarters but at least we’re safe from Vilgax!”

Ben, noticing he have transformed back into a green pony, smiled satisfied.

“Perfect, we’re safe! So now we can reprogram the dimensional weapon and we can go back to Bellwood!”

Celestia finally recovered from the shock and walked toward Ben, who happily waved a hoof at her.

“Hey Princess Celestia, it’s been a while! I am so sorry for interrupting your tea party but we did not have so much control on the dimensional weapon and we landed up randomly!”

Celestia smiled at him. “I’m so glad to see you safe, Ben Tennyson Pie…”

Kevin started laughing at this ridiculous name.

“Ben Tennyson Pie? Really?”

Ignoring him, Celestia continued talking.

“As I was telling you, Ben, I’m glad you’re okay. But I need to discuss some things in private first. Come with me, this way please. The Bearers of Harmony and Rex Salazar can wait here with the others.”

Ben sighed and followed the Princess.

…

In his escape pod, and after drinking something to calm down his nerves, Vilgax grinded his teeth and took a small chip where he copied the dimensional weapon’s coordinates.

“Prepare the remaining ships, and get ready to attack! We have a new objective! No one makes fun of Vilgax!”

Author's Note

So here it is, a fun chapter to make. Pinkie playing/annoying Vilgax as she has all the power of the Ultimatrix. I hope you liked it and as always,

Read ya’ later!

Ben, as a punishment you would write a friendship report and read it in front of everypony

Ben, as a punishment you would write a friendship report and read it in front of everypony

Princess Celestia took Ben to a small study room which only had a desk, a quiver, ink and parchment.

“Princess Celestia, I know that you’re mad, but writing lines?” asked Ben.

Celestia calmed him with a kind gesture.

“Don’t worry Ben, I’m not mad Ben Tennyson Pie! Is it true that I got a little annoyed at first, mostly because it is hard to admit there is a piece of technology more powerful than my magic. But after a little consideration, I realized that I am proud of you!”

“Proud of me?” asked Ben, confused.

She nodded kindly.

“Yes. You trusted in the magic of friendship, so much that you even gave Pinkie Pie that device because you were trusting her your life. In the end, is just the magic of friendship working at is finest. Trusting your life to somepony is the biggest act of friendship you can do. I am proud of you, Ben Tennyson.”

Ben smiled awkwardly, then the Princess pointed a hoof to the desk.

“But you did caused me and my little ponies some problems! Ben, you have no idea the panic that your friend Rex Salazar and Pinkie Pie caused because of you. Because of that, as a punishment, you would write a friendship report and read it out load in front of everypony.”

Said that she left Ben alone, staring at the parchment.

“Oh, come on!”

He spent a whole week living with aunt Pinkie Pie and he was very familiar with the famous ‘friendship reports’ and he knew Kevin wouldn’t let him forget about it.

…

Everypony was laughing and chatting happily when Ben walked back to the group with a parchment on his mouth. Princess Celestia smiled kindly.

“Oh, you’re here Ben! Let’s see what you wrote!”

Just wanting to get over with this as soon as possible, Ben started:

“Dear Princess Celestia, the greatest treasure you will ever find are the friends you make during your life. True friends are forever, and you know that they would be with you no matter what. I’ve been in grave danger in countless times but having my friend by my side gave me the strength to keep going. Giving each other strength in moments of truth is the symbol of true friendship. And the most surprising about friendship is that you don’t know who would become your friends with time. The enemy from yesterday can be today’s friend like my best friend Kevin.”

He had to stop at that point because Rex and Kevin wouldn’t stop laughing. Gwen and the ponies just glared at them.

“You’re doing great Ben Tennyson, please go on.” said Celestia.

Ben sighed and continued. “Where was I? Oh, right! Every friend is different and having them by your side can allow you to complement each other’s abilities. And no matter how big the danger is or how bad the situation is if your friends are by your side, you know you don’t have nothing to fear. Sincerely yours, your friendly visitor, Ben Tennyson. “

“Ben, that was beautiful!” said Gwen, touched.

The ponies smiled at Ben’s report. But Kevin and Rex continued to laugh as Celestia’s patience grew thin.

“You two stop! Or do you want to write a friendship report as well?” said Celestia angrily.

Kevin rolled his eyes with a grin. “Oh, come on! Do you think I would do it just as Tennyson did? I don’t do homework neither here, neither at school.”

Rainbow Dash just flew angrily toward him. “How dare you speak Princess Celestia like that?!”

Kevin simply put his hoof over a stone pilar, becoming stone himself.

“Oh do you want to fight, little girls’ toy? Go for it!”

Rainbow Dash was about to say something when a shadow covered Canterlot.

They looked through the window to see hundreds of small ships surrounding a bigger ship.

Vilgax’s army have arrived to Equestria. Then, the voice of the Conqueror of a Thousand worlds could be heard all over Canterlot.

“Pink pest! Do you think you can just annoy Vilgax without any consequences?! I’ve spent an irritating hour having fun your way, now we’ll do it mine! I will destroy this miserable city and its inhabitants, then I’ll conquer your world too! But first I am going to destroy you and Tennyson to make you pay for that humiliation! I WILL DESTROY YOU!”

“I have a feeling, que esto no es bueno!” said Rex.

Robots started to descend over Canterlot, shooting everywhere, but capturing every pink pony they saw (as they were told by Vilgax). The Royal Guard went to the rescue but the machines overpowered them with ease so they focused their efforts in evacuate the citizens.

Inside the castle, the Princesses, the Bearers, and the visitors evaluated the situation.

“How did this happen? We already defeated the Cthulu impersonator! What the hell happened? Also how did they found us? We brought César’s dimensional weapon with us!”

“Dimensional weapons are pretty common on our world, Vilgax could have copied the coordinates and use it in another one.” explained Kevin.

Twilight high-hoofed.

“That explains how he got here! The thing is that we cannot stay here without doing anything! How do we defeat Vilgax?”

Celestia frowned. “Follow me, we’re getting the Elements of Harmony. Ben Tennyson Pie, now is a good time for you to get the Ultimatrix back.”

Ben looked at Pinkie Pie, who happily offered her hoof to him. “All yours Ben!”

The teenage colt was about to take the watch, but he stopped midway through and shook his head.

“No, Aunt Pinkie Pie. This is your battle.”

Pinkie Pie stood there confused, but then she smiled from ear to ear.

“Thank you nephew! It is my duty to use the power of the Ultimatrix to save Equestria! So who would you suggest me to use?”

“Definitely Confusion! Its unlimited power would be more than enough to defeat Vilgax.”

But Princess Celestia shook her head. “Everything but that Ben Tennyson Pie! Don’t take me wrong, I trust Pinkie Pie as any of you, but I can’t let one of my little ponies to use the power of the God of Disharmony and Chaos. Choose another one, Ben Tennyson.”

Ben stood quiet for a while and then he turned to Kevin and Gwen.

“I see. Guys, use the keys you have made for the Ultimatrix. Is our only chance.”

Gwen seemed hesitant.

“Ben, are you sure?”

“Just do it. She can handle Serena and Belicus.”

Kevin did as he was told.

“Okay, let’s do it!”

“Kevin!”

“Come on, I want to see what the one who made Vilgax cry is capable of with the power of a Celestial!””

They connected their keys to the Ultimatrix, unlocking a new transformation.

“Auntie, this one is called Alien X, the race is called Celestials. The creators of my universe. Once you become one you have absolute control of everything. But you must work together with the other two personalities. Belicus is the voice of aggression, and Serena the voice of heart. And you would become the voice of reason.”

“What do you mean Pinkie being the voice of reason?!” shouted Rainbow Dash.

But it was too late, Pinkie pressed the button of the Ultimatrix turning into the female version of Alien X, with blue eyes instead of green.

“Great so what do we do?” asked Kevin.

“We would buy my aunt some time. Let’s go!”

The three plumbers exchanged a look and ran into action followed by the five friends who were thinking what could work against Vilgax. Also, Celestia and Luna flew to action and joined the fight.

Gwen took her Anodite form, which impressed Twilight very much, and she started shooting mana attacks against Vilgax’s machines forcing them to back off.
Rainbow Dash and Applejack used the tactic they used back at the ship. Rainbow would fly around the robots to make them miss their shots and as they were distracted trying to get Rainbow Dash, Applejack would catch them with her lasso and make them fall.

Twilight’s course of action was to shoot magic beams from the ground, as Celestia and Luna flew around the robotic army and shooting magic beams against them.

Rex Salazar used his cannon to shoots pieces of the streets against the robots, but he seemed thoughtful.

“Is something on our mind, Rex Salazar?” asked Celestia landing aside him.

“I may have a way to defeat many of them at once. But is risky! If I do so there is a huge chance I black out and I may lose my memories in the process. Last time it happened I forgot half of my life and had to remember everything piece by piece.”

“Rex Salazar, if something happens to your mind, I promise I would use my power to help you come back. So please, save my people!”

Rex smiled. “Okay, I would do it because is the right thing to do!”

Rex closed his eyes and focused the best he could. Energy started to flow around his body, as he started to change. After an explosion of white light, Rex Salazar have transformed into a giant robot. It had one cannon on each of its shoulders. A gigantic sword on his right arm, as the left one has transformed into a mechanical hand. Two mechanized legs replaced his back hooves and his trade-mark jetpack appeared on its back.

Rex’s Omega form ran toward Vilgax’s ships and started to destroy them with its giant sword as everypony watched.

“This kid is amazing! I have to thank him when this is over!”

Vilgax saw his army get decimated, but he didn’t care. He was blinded by rage. All he wanted was to destroy the pink pest no matter the cost. No matter what.

…

Pinkie Pie opened her eyes only to find herself in an infinite black space where two giant faces were waiting for her. A man’s and a woman’s face.

“Hey there! My name is Pinkie Pie! Nice to meet you!” greeted the pony.

“Hello Pinkie Pie,” said the woman. “You are not who we were expecting but is nice to have some company at this space.”

The man groaned but he didn’t say anything.

“So you see, I came here because Equestria is in danger because of the big meanie of Vilgax and I would like you to help me to transform all his big bad weapons into delicious desserts! Because my nephew Ben told me you can do anything!”

The two floating faces exchanged a look and turned back to Pinkie Pie.

“No.”

“Please?”

“No.”

“And if I ask you please a hundred times?”

“No.”

“What about a thousand?”

Belicus shook his giant face frowning.

“Listen to me! You can ask us a million times and the answer would still be no!”

“Okay! A million plus one! Please let’s save Equestria, please let’s save Equestria, please let’s save Equestria, please let’s save Equestria…”

…

Rex’s Omega form continued to destroy everything, but Vilgax had ships to spare. No matter how many the EVO take down, more would come from the portal. Also, the ships tried to destroy him but due to his ability to generate nanites he automatically recovered from any damage. They were stuck in an endless circle.

…

“Please let’s save Equestria! Please let’s save Equestria! Please let’s save Equestria…!

“Stop it please!” cried Serena.

“Oh no, that’s cheating! We agreed I had to ask you a million and one times, and we’re barely at the two hundred and five thousandth time! please let’s save Equestria, please let’s save Equestria…”

“STOP!” shouted Belicus. “Okay, okay, okay! We’ll save Equestria but please stop! Just leave us alone for all that is good!”

“Okey-dokey-lokey! Then let’s transform all Dear Mister Vilgax’s ships and weapons into yummy cakes!”

Serena and Belicus sighed.

“Approved!”

…

Pinkie Alien X raised her hand and said with the combined voice of Serena, Belicus and herself. “Transform all Vilgax’s weapons and ships into cake. Approved!”

A shock wave came from Pinkie’s hand and it hit all of Vilgax’s army. Soon enough every single ship or war machine that Vilgax brought with him, and cake started to rain all over Canterlot.

“Pinkie Pie made it!” said Ben.

“Ya’ don’t say!” said Applejack taking a piece of cake and started eating it.

Vilgax was on his mother ship, when the shockwave finally hit it. He didn’t understand what was going on until he realized he was trapped inside of a giant piece of strawberry cake, and he helplessly fell.

One by one the Royal Guard helped the civilians to come out of their shelters once they recognized the menace had been neutralized.

“Pinkie Pie made it!” said Luna.

Celestia agreed. “Indeed she did! This is the power of the magic of Friendship!”

Then the giant robot which was Rex started to walk toward them as it turned back to normal.

“Rex, are you okay? Do you still remember who you are?” asked Ben.

The EVO just winked an eye at him.

“I am okay! It seems that I am learning how to control this thing! It seems that I won’t have to bother you by using your magic on me after all, Princess Celestia!”

“That’s great to hear, Rex Salazar!” said the white alicorn. “I’m just happy you are okay, and thank you for saving Equestria.”

Then Pinkie Pie came skipping happily. “Hey guys! You saw that? It was amazing!”

Rarity noticed she wasn’t wearing the Ultimatrix anymore.

“Pinkie, darling, where’s Ben device?”

Pinkie Pie simply smiled and handed the Ultimatrix over to Ben.

“Here you go, Ben! Your friends Serena and Belicus say hi and please recover the Ultimatrix as soon as possible!”

Ben started to laugh. He was sure they would make him pay for this, so he rathe don’t transform into Alien X for a while.

But then, one of the cakes started to move and Vilgax emerged all covered in whipped cream, strawberries and crumbles.

The heroes prepared to fight, but Vilgax just waved a white flag.

“I give up! This pink pest is too great of an opponent for me to handle!”

Gwen, Kevin, Rex and Ben laughed happily. In the end of the day everything went good for them.

Author's Note

So here it is, another chapter of the story. There is only the closing chapter left and that should be it for the moment. Anyway I hope you liked it an as usual, read ya’ later!

Tennyson, can I borrow your aunt in the future? She may be able to defeat Van Kleiss

Tennyson, can I borrow your aunt in the future? She may be able to defeat Van Kleiss

“How is it?” asked Ben to the Princesses when they came back from the dungeons.

The two exchanged a worried look.

Luna sighed. “To be honest, he is not well. When you take him back to your universe you better find him some professional help. The poor thing is paranoic and the mere mention of a party or the sight of color pink alters him to the point of trying to throw himself throw a window.”

“Booooo! Some ponies don’t know how to have fun!” said Pinkie pouting.

Kevin didn’t say anything unsure what to think. This was the first time they met someone able to make Vilgax cry. Or leave him in such a state. This was unreal.

“I’m just glad this is over!” said Rex relaxing on a coach. “But can I borrow your aunt in the future, Tennyson? She may be able to defeat Van Kleiss. Or put Black Knight on her place.”

They laughed. Canterlot needed some repair here and there, but thanks to Pinkie Pie’s alien X transformation most of what the Princesses needed to do was just some cleanup. During the strange battle the Royal Guard made a great job protecting their little ponies, so no pony was hurt. So, everything would be over after cleaning all the cake leftovers.

Twilight simply nodded.

“So now that the Vilgax situation is over, what about you? Can you return to your universe?”

Rex smirked and pulled out the dimensional weapon César made him. He created the portal, but it got automatically closed.

“Oh, come on! What’s the matter with this thing? Do we have to stay in this crazy pastel-colored world even longer?” asked Kevin, with a frown.

“It may be good for you, Kevin!” scolded Gwen. “A long stay in this world is just what you need for an attitude change! But I’m sure Rex can handle this, right Rex?”

Rex opened the circuit box and showed the group a bunch of strawberry jam on the circuits.

“This is perfecto! My brother César is the genius, I have no idea what to do in this situation!”

“Give me that!” said Kevin taking the dimensional weapon from Rex. “Damn it, I can fix it for sure but I don’t think I could get the components I need on this dimension!”

“So that means you’re staying?! That’s great! I would make a huge welcome party at Ponyville!” said Pinkie Pie happily.

Ben simply patted Pinkie’s back.

“No auntie. As much as I like Ponyville you know we can’t stay. We have our own responsibilities back at home. Kevin has to go back to his garage, Gwen to college, Rex to Providence and me to school. You know that, right?”

“So do you have any suggestions?” asked Kevin, frowning.

Ben simply showed him the Ultimatrix.

“Duh! One of my aliens would to the trick!”

“Oh, so do you have something that can repair advanced machinery?” asked Twilight as she looked at the device.

“At least three! But for today I was thinking about a transformation that can bend the very essence of reality itself!”

Princess Celestia put her hoof on Ben’s shoulder. “Wait just a moment Ben Tennyson Pie! I understand the situation, but I would appreciate if you do not use that transformation again. Please stick with the species who can build machinery, and whatever you do, don’t use Discord’s transformation. That’s an order!”

Ben smirked. “You heard her, guys. She gave me an order!”

Kevin and Rex laughed at this, as Gwen rolled her eyes and chuckled.

“I don’t see what’s so funny!” said Princess Luna. “My sister means it!”

“Yes, but Ben had always have problems following orders, and authorities in general.” said Gwen.

“No matter if they are Magisters from the Plumbers, Azmuth, or any other authority who tries to put Ben in line.”

Ben nodded and much to everypony’s horror, Ben activated the Ultimatrix and transformed into some sort of creature made of different animal parts. A goat’s head, a lion’s paw, an eagle claw, a pegasus’ and a bats’ wing, and a snake’s tail.

“Confusion!” said Ben.

“Órale! And what does that thing does?!” asked Rex.

Ben smirked and snapped his eagle fingers, creating a pink cotton candy cloud out of thin air, that started to pour some sort of orange rain.

“Mr. Smoothie rain!” announced Confusion happily as he started to drink from the cloud directly.

“Really?” asked Kevin.

“What the hell?” asked Rex.

“I can literally do anything with this dude! He haves complete control of reality itself, laws of physics, anything I want! Is like having all the powers of Alien X without having to negotiate with Serena and Belicus. Isn’t this thing the best?”

Gwen shook her head in disbelief.

“Ben, just wait a second! If what you’re saying it’s true, do you realize you cannot afford to lose the Ultimatrix ever again? If Vilgax, Agregor or anyone puts its hands on the watch and turns into this thing, there would not be a way to stop them!”

“Blah, blah, blah, you worry too much Gwen! Let’s just get out of here!”

He snapped the tip of his tail creating a door and opened it, revealing the Null Void.

“What about the Cthulu Impersonator?” asked Rex.

“Oh, thanks for the reminder Robot-Boy!” said Confusion as he raised his hands and making a box in the middle of the room.

“Oh, what’s inside?!” asked Pinkie Pie.

“Open it and you would see!”

Pinkie giggled happily and opened the box, allowing balloon animals, confetti, streamers, cupcakes, fruit punch and other snacks to come out, alongside with loud music and bright lights.

A complete party.

Finally, Vilgax approached on the main door escorted by two royal guards. He was looking down seemed defeated, but then he noticed the party. His whole body started trembling as his eyes scanned the whole room until they fixed on Pinkie Pie.
Vilgax screamed in horror and ran through the door that led to the Null Void as fast as he could.

“Huh, we broke him!” said Kevin, feeling a bit worried for the conqueror of a thousand worlds.

Rainbow Dash couldn’t believe it. “Damn! I knew Pinkie Pie was a nuisance from time to time, but this is a whole new level!”

“We better take note of this for the next time! Never thought parties could be used as a weapon!” said Applejack.

“That settles it! I am going to ask her for help next time I get across Van Kleiss!” said Rex Salazar.

The others nodded and gulped. Poor alien guy!

Ben then turned back to normal. “Alright guys time to leave!”

Kevin groaned in relief and crossed the door followed by Gwen.

Ben turned to his adoptive aunt one last time and hugged her as he waved a hoof to everypony else.

“I guess this is goodbye auntie! Thank you for saving my behind back there!” said Ben.

“Hey, what are friends and family for?” smiled Pinkie Pie.

They hugged for the last time and then Ben turned to Princess Celestia, who smiled at him.

“Take care, Ben Tennyson Pie. You are welcome to visit at any time but I would appreciate if you stop using that transformation in my presence. Seriously, nothing against you but Discord and I have some history and I am not used to see him without getting nervous!”

Ben nodded. “I am sorry Princess, I only did it because it was the quickest way to go back home. And on the Null Void we have more than enough pieces to repair the dimensional gun to send everyone home.”

Twilight smiled and used her magic to take the damaged dimensional gun. “Hey, if you have more than enough pieces do you mind if I keep this one? I am very into science and I would love to learn about what you have in your world. Can I?”

Ben looked at Princess Celestia, who nodded. “I don’t see why not. Is not something as potentially dangerous as the Ultimatrix.”

Twilight cheered as she looked at her new acquisition and showed it to her friends.

“Fascinating! Imagine how much we can learn from this!”

“And maybe you can fix it one day so we can go to visit Ben, or Ben visit us!” suggested Pinkie Pie.

“Of course, I’ll make sure to work extra hard.” assured Twilight.

With that Ben simply waved at them for the last time and crossed the door back to the Null Void before it disappeared. Two universes were safe and now Vilgax was broken beyond repair. Everything was going well.

Author's Note

So this is it, the end of the story. I am sorry for the delay but anyway I hope you liked one of my first crossovers. Hope you liked it and,

Read ya’ later!!

Vilgax cannot put his hands on the Ultimatrix. This is why I need you to keep it safe aunt Pinkie Pie!

Vilgax cannot put his hands on the Ultimatrix. This is why I need you to keep it safe aunt Pinkie Pie!

Twilight was happily whistling as she was walking around Ponyville. The town was getting ready to the Summer Festival. It would be a great celebration, twice as big since last year’s celebration was interrupted by Nightmare Moon. Not only that, but Twilight was also celebrating a year of friendship with the girls. Her dear friends. The lavender unicorn was in a really good mood, and she was ready to the celebration. There was only one thing to do left, and that was to check the preparations in Sugar Cube Corner.

Spike was the first one to react. It was silent, too silent. He was about to warn Twilight, but it was already too late. Pinkie stampeded to the main plaza and crashed with Twilight at full speed.

“Pinkie Pie!”

Pinkie shook her head giggling, as she got back on her hooves and started to jump over the same spot over and over.

“Oh, hey Twilight! I’m sorry but I’m just too excited! My Pinkie-sense is telling me that a huge adventure is about to start and I’m dying to know what it would be!”

“Do you think it would be something dangerous?” asked Spike, eating his claws.

“I have no idea; this is why I am so excited! Last time I felt like these I got a nephew from a different dimension! Remember Ben? Oh! He may come to visit!”

Twilight shook her head as everything that happened when Ben came to visit came back to her. “Okay, I better warn the others that something big is about to happen.”

“Okey-Dokey-Lokey!” cheered Pinkie Pie happily bouncing to enjoy the festival. “We still have plenty of time! The adventure wouldn’t start until nightime! Ehehehe!”

Twilight and Spike watched her leave.

“Is a good thing we have enough time to prepare then!” said Spike.

Twilight agreed. “You’re right! I swear I would never understand this pony!”

…

A powerful red light disturbed the peace of Everfree Forest, as it was slowly transforming into a portal. A young pony rolled through the portal and crashed into a big tree. He was a 17-year-old colt with short black mane, bluish gray fur; dressed in a red and orange jacket and a welder goggles on his head. The colt complained in pain as he rubbed the bump on his head.

“That was nada bien!” complained colt as he stood back on four legs. Then he gasped and took a good look at his new pony shaped and gasped, but he recovered from the shock he nodded. “So, this is what Tennyson meant when he told me my body would change.”

Ben’s last words came to his mind as he was shooting him with that dimensional weapon designed by his brother César. “Pinkie Pie, remember that name Rex. I need you to hand over the package to her and no one else”.

“So, Pinkie Pie,” said the colt. “Where I am anyway?”

A roar, followed by a putrid smile made Rex go back to reality. He turned, only to see a wolf-like creature, who looked like it was made by different pieces of wood, leaves and such. Rex raised an eyebrow.

“Órale! And I thought that I’ve seen everything with Providence!”

The wooden wolf jumped over Rex, who jumped backwards to dodge the attack. The wolf roared in anger and he tried to use its wooden claws to get the kid. Rex raised a hoof to protect himself, turning into a gigantic robotic hand that blocked the attack.

The Timberwolf was taken aback for this sudden change. Rex took its shock as an opportunity to jump on the creature’s back and put his hooves on the back of its head, activating his nanites to cure it.

A strange glow surrounded Rex’s hoof. The Timberwolf roared in annoyance, and it shook its whole body send Rex flying against a tree.

“Qué diablos? Tennyson told me my powers would still work here… oh right, this thing isn’t an Evo.”

He jumped just in time right before to dodge another attack from the monster.

Rex smirked. “Okay puppy, it’s time to teach you some manners! I’ve fought things bigger than you!”

He transformed his right hoof into a huge cannon. The back end of the cannon enlarged and took a huge chunk of the soil, compressed it and shot it to the monster. The impact turned the Timberwolf into pieces.

“Did you like it, ugly? No one can mess with Rex!”

But then he noticed how the pile of wood started to float surrounded by a green aura and started to reform the monster.

“Perfecto! Time for me to get out of here!” said the colt transforming his hooves into a motorcycle, and escaped as fast as he could.

He had no time to waste fighting a self-healing monster over and over again. He had to find this Pinkie Pie, but where to find her? Then he noticed on the package Ben gave her. It started beeping and shoot a light to north.

“Huh… that’s convenient!”

As he started to go north, he noticed he was on the deepest part of a forest. He could feel the creatures staring at him as he passed by. Groaning, Rex went faster hoping he could get to civilization before nighttime.

…

After last year’s fiasco, Ponyville decided to go all out for this year’s summer celebration. By Pinkie Pie’s suggestion they decided to celebrate with a big night festival waiting for the glorious moment when Princess Celestia raise the sun and officially starting the summer. The ponies also went as far as to put some kiosks around the town so ponies big and small could come and have fun. And finally, after days of planning, the festival was up and running and everypony was having fun.

Pinkie Pie and her friends were walking around the festival when suddenly, Applejack groaned in annoyance.

“What’s the matter Applejack?” asked Rainbow Dash.

The cowpony simply aimed a hoof to one of the kiosks, and the six friends groaned annoyed. The owner of the kiosk was a blue unicorn with silver blue mane and a purple cape. And to make things worse she waved at them happily.

“Hello ladies! Do you want to try your luck with the Great and Powerful Trixie?”

“What are you doing here?” asked Rainbow Dash with a frown.

“Well, Trixie paid the fee so she can set up her kiosk here! This is a completely legal business. All you need to do is challenge Trixie to do something better than you do. If you win you owe Trixie five bits. But if you beat Trixie, Trixie pays. I’ve lost some rounds but won the majority! Wanna try?”

Rainbow Dash smirked with a determined look on her face. “Of course! Let’s see if you can…”

Applejack pulled her friend’s tail to make her stop. “Easy Rainbow! Ya’ cannot spend a single day without challenging soempony? Come on, do not waste yer’ money with her! Is not worth it!”

“Are you saying I’ll lose?” asked Rainbow Dash.

Trixie smirked from her kiosk. “Well, Trixie may not be as gifted as Twilight Sparkle but she still has some skill on her own. So what do you say cowpony? Wanna try?”

Luckily for them, Pinkie Pie interrupted by starting to bounce on the same spot over and over.

“What is it, Pinkie Pie?” asked Fluttershy, worried.

“The adventure is about to start!”

The six friends immediately started to look around, ready to face everything and everypony. And finally he arrived, a bluish gray earth pony colt with a red and orange jacked and goggles on over his head.

“Hasta que al fin! I swear to God, that damn forest seems endless! Ya qué…”

The six friends were about to ask him who he was or where he came from, but Trixie walked towards him first.

“Hey kiddo! Want to earn some money? Are your willing to take Trixie’s challenge?”

Rex shook his head in confusion, but he just smiled kindly. “Well, that sounds neat… I could use some cash. But I don’t have any money with me, maybe some other time!”

Trixie smirked. “If you lose you don’t have to pay Trixie with money. You just have to become Trixie’s assistant for the rest of the night, helping Trixie by bringing customers to her.”

Rex though about it for half a second and nodded. “Huh… that may help me to talk to a lot of ponies and find the pony I’m looking for. Either way I win. Okay, what is the reto amiga?”

“You have to do something and if Trixie does it better, Trixie wins! What do you say?”

“Hey partner, A’ wouldn’t do that if A’ were ya’!” warned him Applejack.

But Rex has already walked toward Trixie and put on his goggles.

“So I just do my thing and you do better? Okay, prepare the money amiga, because I am going to show you what I’m capable of!”

Two giant turbines appeared on Rex’s back, and he used them to hover over the ground with a smirk. Then he made the turbines disappear and landed over his back hooves turning them into huge, mechanized legs. Finally, Rex made the mechanized legs disappeared, and then he turned his right forehoof into a giant sword and swung it around.

Trixie’s jaw dropped as she levitated a bag of bits to Rex, and she started to move backwards completely horrified.

And Trixie was not the only one. Everypony around was looking at Rex with fear and started to walk backwards avoiding eye contact.

“Okay, maaaaybe I did not thought enough about this!” mumbled Rex to himself.

“A MONSTER!” shouted somepony among the public.

Everypony panicked and started to run away, except for the six bearer of harmony facing Rex ready to fight.

“Please!” said Rex going back to normal. “I mean no harm… I am just looking for somepony! Pinkie Pie, does anypony knows Pinkie Pie?”

Rainbow Dash flew toward him, frowning. “And what if we do? Who are you and what do you want with Pinkie Pie?”

Rex smiled and moved backwards still raising a hoof showing that he meant no harm. Twilight was about to intervene, when Princess Celestia herself landed between the six friends and the visitor.

“Hello there, young fellow. That was quite a show you pulled! Can you please tell me who are you and what do you want with Pinkie Pie?”

Rex looked at the newcomer. She looked at her up and down and nodded. She must be the Princess that Tennyson told him about.

“My name Is Rex Salazar, and I’ve brought a message for Pinkie Pie. A message from Ben Tennyson!”

Everypony gasped at the revelation, but after shacking her head, Princess Celestia looked at Rex.

“Sorry young colt, did you say Ben Tennyson?”

Rex nodded.

“Long story short, a friend of mine called Breach told me to a crazy dimension called the Null Void. Luckily for me, the Void is used as a prison for galactic criminals; and my old friend Ben was completing one mission there. He was about to help me go back home when we got ambushed by one of his enemies. A lot of things happened, and he ended up sending me here to look for Pinkie Pie.”

“Plumbers?” asked Princess Celestia. “There was a leak at the Null Void or something?”

Rex shrugged. “I know that sounds ridiculous, but according to Ben, Plumbers are some kind of intergalactic police force.”

After a few minutes of silence, Twilight finally nodded. “So let me see if I get this right, you are not from Ben’s dimension?”

“Nope, he just showed up at my dimension and cause a bunch of trouble but we ended up as friends.”

Rarity nodded. “Yes, that’s our Ben!”

At Princess Celestia’s sign, Rex handed over the green box Ben gave to him. Celestia examined it and then it gave it to Pinkie Pie. Pinkie pressed the button on the green box and suddenly an holographic projection of Ben in human form appeared right in front of her.

“Aunt Pinkie Pie! You may not recognize me on this form, but I can assure you I’m me! This is how we look on my dimension. By the way how was your trip, Rex?”

“Dude! I could use a warning! I cannot get used to be a walking-talking horse.” complained Ben looking at his new body.

Ben chuckled at this, but then the shift he was in was shot and trembled all over.

“Auntie, I guess that Rex already told you the basics. We’re at the Null Void, we were running an official investigation. But it ended up being a trap from an old enemy of mine: Vilgax.”

Ben took a deep breath before continuing.

“Vilgax calls himself the conqueror of a thousand worlds, and he wishes the Ultimatrix more than anything else. And if puts his hands on it, more worlds would fall before him. Vilgax’s army is too big and sooner or later he would capture me despite Rex, Gwen and Kevin are on my side. This is why I told Rex to go to Equestria. Vilgax cannot put his hands on the Ultimatrix. This is why I need you to keep it safe. No matter what, keep the Ultimatrix away from him.”

Rex when he heard that, just as the rest of the ponies. Princess Celestia and Twilight tried to stop the container to go to Pinkie Pie but it was already too late. The device has attached itself to Pinkie Pie’s hoof.

And they knew nothing they could do would be able to ever remove it from there.

Author's Note

So here it is, the second part of my Ben 10 Ultimate Alien crossover. Ben wouldn’t have a big role in this story. This time Pinkie Pie and rex would be the stars of the story. Anyway, hope you liked it and,
