Sonic goes in Equestria and meets a new monster on the way... the Thinworx!

Sonic goes in Equestria and meets a new monster on the way... the Thinworx! This is my first story so if it's bad, don't say anything negative. P.S I own nothing but the plot.

UPDATE 2021: Well, here we are... my start. Am I proud of it? Not really, no. But hey, we all have our beginnings somewhere! Now, come and observe my first ever story on this site– edited just enough to meet FIMFiction's publishing standards! Speaking of which, since my old description doesn't quite have much and I refuse to replace it and tarnish my message of reposting this, this is a poorly written story about Sonic the Hedgehog entering the MLP universe and also colliding with the Epic Mickey universe. During which rivals from Sonic's world return alongside old enemies from the MLP universe, both of which using technology and powers from the Epic Mickey universe.

Chapter 2: The Thinner Disasters

Sonic and his crew ran to sweet apple acres to find rubble.

“Get this varmint of mah farm!” said Applejack.

“SONIC I CAN’T STOP!” said Knuckles wrecking the farm to it’s knees.

"Let’s restrain him!” said Sonic. When they did he broke free!

“YOU FORGOT?!” exclaimed Knuckles.

“What?” asked Rarity.

"He’s super strong.” said Rouge.

“I got an idea!” said Sonic. Sonic ran around Knuckles with his super speed.

“Whoa!” said Rainbow Dash shocked.

  “I was guarding the master emerald when I saw a strange figure like HER.” said Knuckles pointing at Rainbow Dash.

"Did she have a yellow mane?” asked Rainbow Dash.

"Yep, she also poured green stuff on the emerald and it turned invisible!” said Knuckles.

Then out of nowhere, “WHAT WERE YA DOIN’ TO MAH FARM?!” exclaimed Apple Jack.

“Hey I’m Sonic and this is Tails and Knuckles.” said Sonic.

"As long as he won’t wreck mah farm again he’s fine by me.” said Apple Jack.

“PLEASE STOP!” said a strange voice.

“Who’s that?” asked Sonic.

"That’s Fluttershy!” said Twilight.

"Let’s check her!” said Rarity.

“Let’s go!” said Sonic.

They ran to Fluttershy’s cottage to find a gray Cream, flinging, smashing, whacking, and pushing.

“I can’t stop Mister Sonic!” said Cream. Twilight did her spell quickly on Cream.

"I’m SO, SO sorry!” said a sad Cream.

“It’s ok” said Fluttershy.

“HI PALS!” said a hyper-active voice.

"Hi Pinkie”. said Rainbow Dash.

“AHHHH!” said Sonic running from a pink hedgehog .

"SONIC COME BACK HERE!” said Amy.

"GUYS PLEASE HELP ME!” exclaimed Sonic.

"Now's not the time for a wild goose chase," said Tails.

Pinkie Pie jumped in front of Amy.

“Hi who are you people are you new? Well I’m Pinkie Pie and this is - AHHH!” She said while seeing a green tidal wave destroying everything!

“AHHH!” said a strange voice.

“Run Mickey!” said a stranger voice. “Who in tardation are yall?” asked Applejack.

“We’ll talk later, but now RUNNNN!” said the creature. They ran to a green house.

“We’re all here so I’m Gus and this is Mickey and Oswald.” said Gus.

"Gosh! well I’m off to re – paint this place!” said Mickey.

"Uh – paint?” asked Tails.

“Just watch.” said Oswald. Mickey used his brush, and a house came colorful again!

"Whoa!” said an amazed Tails.

“He can also make it gray again but he’s not. I have a remote that can operate machinery.”

“Let’s go old chaps!” said Gus.

"Well let’s go already!” said Knuckles.

"Not so fast!” said the evil voice.

"SOMBRA?!” exclaimed Twilight.

"What do you want cloudy?” asked Rainbow Dash.

“I think I know!” said Mickey.

“What?” asked Sonic.

“We’ll explain later Sonic but we need to go!” said Oswald.

“Okay now that you know me you all must know a more evil duo is coming. Muhahahaha” said King Sombra.

He teleported away. “By Jove!” said Gus.

“So you know what’s going on?” asked Amy in a detective voice.

"Uh...no." said Mickey getting worried. Amy was trying to convince Mickey to spill his beans about what’s happening.

"I can’t say I swear!” said Mickey.

“Pinkie, do your stuff.” said Rainbow Dash.

“Stuff? What stuff? Hey,  why’s the town gray? Why are the ponies scared?” asked Pinkie Pie.

"I swear I can’t say! Besides I faced singing pigs!” said Mickey.

"Alright then, it’s time for OUR secret weapon. Rouge?” said Sonic. [ Refrenced to the Sonic Generations modern Sonic Rouge challenge.] “What’re you doing? Oh no, NOOOOO!”  exclaimed Mickey.

“Spill it rat!” said Rainbow Dash.

“I’LL TALK! JUST MAKE HER STOP!” said Mickey.

Chapter 3: The Stories [and Secrets]

“The truth is I was in my house when…” said Mickey in a flashback. Mickey was sleeping when something happens.

"Hey? What’s cookin’?” asked Mickey when he heard a bubbling sound. Mickey went through his magic mirror to see some mongoose – like figure.

“Yes, I think it worked.” said the figure.

"What do I do?”  whispered Mickey.

"With the blotworx parts I’ll get revenge on him!” said the person.

“Blotworx?!”  whispered Mickey.

Mickey read a poster learning his name is Ash.

“Ash?”  asked Mickey. Ash saw a shadow of Mickey.

“Who are you? How did you get in here?” asked Ash trying to grab him.

"AHHHH!” Said Mickey running for his life.

“I ran and ran until I tripped someone over.” said Mickey.

“WHOA!” said a voice Mickey didn’t hear,

"GET ME OUT OF HERE!” said Mickey running to the mirror to wasteland to get Oswald and Gus, and something sent them to Equestria.

"So there you have it.” said Mickey,

“ASH, ASH MADE US MEET?!” exclaimed Sonic.

“Who was the one Mickey tripped over?” asked Rainbow Dash.

"Who is she? She is the one with the spatters, don’t you see?” Sang the Mad Doctor.

"Doc!” said Oswald.

  “I’ll tell the plans they have in store, I’ll say they plan to destroy our worlds and more, at THE MAD DOCTOR’S WONDERFUL WORLD OF EVIL! MUHAHAHA DAHAHAHA!” sang The Mad Doctor. So Sonic , Rainbow Dash , and his gang went to his attraction.

In his film the Doctor sang

“Welcome, boys and girls, to the wonderful world of evil, and today I have a tragic vail for you. I needed an army so I created blotworx. Blotworx are beetleworx, but spatters were unpredictable and had to be cast out. Then it went static. I had no choice, but to sell them, to someone named Ash, I upgraded beetleworx with the cash. Ash have left Mina, that’s bad right from the start, right now our worlds are falling apart!”

“Come on! Lets go!” Said Princess Twilight flying to the projector.

"Was Twilight always like that?” asked Sonic.

“Why, no Sonic.” said Rarity.

“First my friends’ cutie marks got mixed up…”So Princess Twilight explained the cutie mark mix – up [Season 3 episode 13]

"When we did the spell I fulfilled my destiny as Equestria’s newest princess!” said Princess Twilight.

“Neat!” said Amy. Just then, a monster came in!

“What is that?!” asked a shocked Gus.

“A thinworx!” said King Sombra, just then, A BIG CLOCKTOWER CAME!

"THIS IS FOR OUR WORLDS!” said a voice in the anamatronic.

"Hello my friends I taught Mina to control robots, now… REALESE THE POTS!” sang the Doc.

“Got it doc!” said Mina. She blasted pots and pans at the monstrosity. It came at Fluttershy,  “AHHHHH!” exclaimed a REALLY scared Fluttershy.

“I got it!” said Mickey painting the monster. It turned blue and stopped.

“1 down - 100,000,000  more to go.” said Ash.

“Who are you?!” asked Rainbow Dash.

"Ash”. said Sonic. Just then, the anamatronic raced at him in rage!

Just then a lightning bolt sliced the clocktower.

“Thanks LD!” said Ash.

“LD?” asked Mina.

“Welcome Ash!” said a voice.

"LIGHTNING DUST!” said Rainbow Dash.

"Well, if it isn't Rainbow Crash.” said Lightning Dust.

“Hey this varmint nearly killed us!” said Applejack.

Mina coughed from the dust and metal.

“AHHHHH!” said Pinkie Pie. The anamatronic lost control and thinned out.

“Uh oh.” said Rainbow Dash seeing Ash and Lightning Dust disappear.

“I’ll go after them with my beetleworx, stay and defeat the thinworx.” sang the Mad Doctor.

"Well lets go!” said Sonic.

So Sonic and his new friends took out the thinworx. Meanwhile…

“Get back here!” said the Mad Doctor.

“Try and make me!” said as the Doc ran toward Ash to be attacked by a bird!

“Take that!” said a tween voice.

“Gilda!” said a mad Mad Doctor for him and Gilda got on the wrong foot.

"I remember you!” said the Mad Doctor

"Oh, hi Doc!” said Gilda. The Mad Doc was thinking back when he and Gilda were friends when… she turned.

“You became a monster!” said the Mad Doc.

“Oh you’re just over exaggerating.” said Gilda.

“You said I’ll control the blotworx!” said the Mad Doc.

"So?” asked Gilda.

“So, they nearly destroyed Wasteland!” said the Mad Doc.

“DOC!” said Sonic.

“We found something weird.” said Amy with a tiny pink thing.

"Ah yes, a magic guardian. You see, one day a giant star cycled Wasteland thus bringing magic and blot guardians!” said Gus.

“GILDA!” exclaimed Rainbow Dash.

“Go to the “place!” said Ash.

“I’ll be back!” said Gilda. She, Ash, and LD took off again.

“You KNOW her?” asked the Mad Doctor in confusion.

“She was my old friend in Cloudsdalle, until she treated my new friends terribly!” [season 1 episode 5] said Rainbow Dash.

"Huh. She was my old friend too!” said the Mad Doc.

"Weird”. said Mina.

"Well, let’s get a move on!” said Sonic.

“We need to think where they’re goin’!” said Oswald.

Just then they saw a BIG thinworx with a crown and beetleworx legs!

“That must be the ruler!” said Rainbow Dash.

Mickey tried painting and thinning but nothing happened. Just then it grabbed the Doc!

"NOOOO!” said Oswald.

“Huh?” asked a small voice.

"Spike!” said Twilight in glee.

“It’s horrible! Ponyvillle is under attack!” said Spike.

"They must’ve headed there!” said Mina.

“Well let’s go!” said Sonic. They headed for Ponyville, only to find waste!

"No!” said Rainbow Dash. Just then Lightning Dust came along – wearing shadow bolt clothes!

“Hi RD!” said Lightning Dust.

"Hey! That was my Nightmare Night costume!” said Rainbow Dash.

“Well the cape is new. It’s what I’ll be wearin’ in this new world me and Ash will rule!” said LD in an odd trance.

“By your trance I know where this is going.” said Mina.

Chapter 4: Darkened Love. [A.K.A: Ashdust]

“You don’t mean…” asked Sonic.

“Yep. LD has a crush on Ash!” said Mina.

“Well, we should of seen that coming! said Gus.” Then a blot pool bubbled!

“YOU GUYS MADE A BLOT POOL IN EQUESTRIA?!” asked Mickey in shock.

“Yep.” said Ash.

"No!” said Spike seeing Carousel Boutique inert!

“Friends I need your help!” said a Spanish voice.

“JAMFACE!” exclaimed Gus. “I’m trapped in here! This cage is dropping to the thinner pool!” said Jamface.

"Amy, use your guardian!” said Gus.

“Ok!” said Amy. She used her guardian and Jamface floated out.

"Thank you my friends!” said Jamface in relief watching the cage fall.

“No problemo!” said Oswald.

"I’ll get ‘em!” said Knuckles.

“No, WE’LL get them. Team huddle!” said Sonic calling the Mane 6, Mickey, and Oswald over.

"We need to get to their lair in my world. We can take the projector Ash and LD used.” said Sonic. They jumped into a “ My little pony” labeled projector.

They headed there when… the blot pool raised and flew in it! Ash jumped in the way and grew and grew to the storm blot!

“No!” said Sonic.

"Yes!” said LD no longer in the trance.

“Yes! I have done it!” said Ash in a darkened voice.

Then LD was racing to Sonic’s world when the thinworx leader hopped in the way!

"AHHHHH!” shouted LD being eaten in one bite whole!

“Whoa!” said Sonic. Blot Ash headed straight at it!

"Really?” asked Gus. They went to Ash’s RV

"What do we find?” asked Sonic.

“Ah know.” said Applejack.  AJ found a button that changed the RV to a big lair.

“Whoa. Good work AJ.” said Sonic looking at the giant core. Then, Blot Ash ate the RV. then, Oswald found the Mad Doctor!

"Doc!” said Oswald.

“Mickey hand me the brush!” said the Mad Doc.

Mickey was confused.

“It may sound crazy, but it’s either give me the brush or watch everyone and everything turn inert and they will destroy our worlds!” said the Doc.

Mickey handed him the brush, then he painted in the bridge

“Yeah!” said Mickey. Then, a thinworx smashed Mickey!

“Welcome RD!” said a new LD!

“How did you survive? Also nice makeover.” asked Sonic.

“Do you think we were fools? We programmed them to become what they eat!” said LD.

“Oh NOW the legs make sense?!” asked RD.

"Mick, Oswald you take care of the blot while we take care of the inside!” said Sonic.

“Ok!” said Oswald.

“Split up! AJ and Knuckles take down that center core! TS and Tails go take out as much blot as possible! Pinkie and Amy take care of replacing the brain! Rarity and Rouge take care of it’s eye sight! FS and Cream call your friends to help out! RD we’re taking care of this thing!” said Sonic. So the epic fight began! Mickey and Oswald were on the outside.

“Okay we need a plan… I know! Mickey, use paint to take out the arms while Oswald makes a diversion!” said Gus.

Sonic and RD were fighting Thinworx Queen Lightning Dust.

"Get back here little guys!” said LD in power.

Meanwhile Mickey painted in the arms.

“What’s going on?” asked LD shaking in motion.

“You will NOT listen to a cartoon brush - cuddling rat! You will listen to ME!” said Ash struggling so hard he making some of the blot explode off!

“What happened?” asked Sonic.

"Change of plans! The others must distract the blot while we make it shrink to nothingness!” said Gus.

“You heard him!” said the Mad Doc.

“Alrighty then.” said Sonic. They did this until the blot wouldn’t explode.

“What happened?” asked Knuckles.

"I’m not a fool! I made it not explode one last time!” said LD. Ash knew LD had a crush on her. So did he!

Sonic knew this and was anxious to see who’ll tell first. Sonic was just about to find out. Pinkie and Amy made the brain explode to make thinner explode a port behind LD’s pod.

“What?” asked LD. Mickey and Oswald came in and reprogrammed the port.

"NOOOOO!” said LD turning to normal. The paint blot repainted the worlds and the blot exploded.

“No... No!" said LD freaking out. Just then Ash started whispering to her. Sonic eavesdropped. After Sonic stepped back his eyes were wide.

“What happened?” asked Rainbow Dash.

"Remember when we were so anxious to see who tells about the crush?” asked Sonic.

"It was both.” said Sonic.

Chapter 5: The Thinner Generator

Sonic looked back to see nothing.

“Again?!” asked Sonic.

"Let’s git ‘em!” said AJ.

"They must be heading in whatever “The place” is!” said Sonic. Then a BIG beacon came out of nowhere.

"A portal!” said Tails. They hopped in to find a thinner dam!

“WHOA!” said Mickey.

“How did they –” asked Mina.

"Those tubes must be connected to the thinner pools!” said Gus. Then the beacon banged up! A big wave splashed.

“Of course! This must be the cause of the thinner waves!” said Sonic. Then Ash charged at Sonic!  The Doc knocked him out of the way! The Doc is now falling to his death.

“DOC!” said Oswald.

“Shame. To bad he’s toon.” joked Ash. Oswald turned in rage trying to shock him to be flown away by LD.

"Oswald!” said Mickey. Then a portal opened for LD to throw Oswald back to Wasteland. He flew out, then Gilda pushed him in.

“Bye!” said Gilda.

“Welcome to “The place” Sonic!” said Ash.

Sonic was face to face with Ash.

Then a thinworx grabbed the rest but Sonic, RD, and Mickey.

“Time to die!” said LD.

Mickey thinned the thinworx.

"Wow! Send another one, oh, and the rat’s brush.” said LD. It ate it and got cannons! It tried to blast then it turned green and got sick.

“Wow!” said Lightning Dust.

"You can’t eat the brush.” said Mickey.

“I’ll get Oswald back while you fight.” said Gus.

"OK.” said Mickey. So they fought while Gus rounded up Oswald, Ash then snatched Mickey’s brush from his hands.

“Hey!” said Mickey. Ash then thinned RD’s wings

“OWWW!” said Rainbow Dash in pain. Ash splashed Sonic to the end of the dam. They thought it was over, then a robot hand shot out!

“YOU WILL NOT HURT MY FRIENDS! LET THEM GO!” said the animatronic Mad Doc. Holding the thinner generator and threw it in the rest of the thinner.

"OK, OK!”said Ash, so he let Sonic go. Just then a cart came with Princess Celestia. “Celestia!” said Princess Twilight.

“Shall we take them away?” asked Guard #1.

“Let Twilight do it.” said the goddess.

“Really? Oh, thank you Princess Celestia!” said Twilight in joy. So she took them away. Then Gus came with Oswald.

“Oswald!” said a painted Mad Doc. Then a sparkle came and a familiar wizard came… Yen Sid!

"Yen!” said Celestia.

"You know him?” asked Mickey.

"He has a library section in Canterlot!” said Celestia.

"Wait, I thought Star Swirl the Bearded does.” said Twilight in confusion.

“Ahh. You have completed my life – long spell.” said Yen Sid.

“Wait are you…” asked Twilight. Then Yen Sid grabbed his brush and dabbed thinner on his hand to reveal a blue hoof.

“My name is Star Swirl.” said Yen. Mickey was in shock. So was Twilight meeting her hero.

"You see, I tried to perfect my new form but failed, then I created Wasteland. Many years later you completed it!” said Star Swirl. So Yen Sid opened a portal for Mickey, Oswald, and Gus to go home.

Then Sonic frowned.

“What’s wrong?” asked RD.

"I've  just realized, after all my friends I lost, I now have to leave my greatest.” said Sonic.

“I belive I can help with that.” said Twilight. So she used a spell that made a bright light. Then Sonic looked around and realized what happened… Mobius and Equestria merged! So Ash and Lightning Dust went to prison. THE END.

Chapter 1: The Beginning

One day when the wind was calm and the city’s people were at peace Sonic was ready for his combat training when something ran to Sonic!  It laughed at him and said

"YOU SHALL DIE!” So sonic rushed to his friends at super speed!

“GUYS SOMETHING’S ON ME!” Sonic screamed. So Tails blasted it off but it opened a portal sucking everyone in!

“If we stay together we’ll be fine!” Tails yelled just as the evil separated them! They split through time and space. Along with more people…

When Sonic woke up he was in a weird forest.

“Where am I?” Sonic said. Then someone or something was running into him! Then Sonic got in a mud puddle, then a voice said

“Don’t worry I’ll get ya out!” Then Sonic got flown out of the puddle. Then Sonic saw a strange figure that looked like a small horse.

“Hi I’m Rainbow Dash” the horse said.

“Who are you?” Rainbow Dash asked.

"I’m Sonic – Sonic the hedgehog. What are you?” Sonic asked.

“I’m a weather patrol pony!" Rainbow Dash said.”

“Oh..." Sonic said.

As they were walking in the forest they found Tails and Twilight!

“Tails! Finally!” Sonic said.

"I finally know where we are!” Tails said. “You’re in the Everfree Forest!” Said Princess Twilight.

"That’s a forest horror – jail.” said Tails.

“Everfree? Sounds like a free - forever place.” said Sonic.

“If it’s a Halloween place make it called “ doom land” or somethin’.” said Sonic.

The crew went to ponyville only to hear “AHHHHHHHHH! THIS IS JUST TERRIBLE!”

“Who was that?!” asked Sonic.

“That was Rarity!” said a nervous Twilight.

They ran to the boutique to find Rouge – gray and stealing everything!

“Rouge what are you doing?!” asked Tails.

“Wh – hi S- Sonic I can’t move!” said Rouge.

A shocked Rarity shouted

"PLEASE MAKE HER STOP!” So Sonic and friends went to work trying to stop Rouge, but failed trying.

“I got it!” shouted Rainbow Dash.

“PLEASE DO WHATEVER YOU MUST!” shouted Rarity in horror.

“What is it?” asked Sonic.

"Twilight use your memory spell on her!” exclaimed Rainbow Dash.

“I’ll do my best!” said Twilight and Tails at the same time.

“Whoa, we found our copies.” said Tails. So they went to work reforming their bat rival. Rainbow Dash restrained her while Twilight was doing her spell on Rouge.

“What happened to me?” asked Rouge.

“What DID happen?” asked Sonic.

“I saw a dark smoke cloud and … well you get it.” said a dizzy Rouge.

“It got us here too.” said Sonic.

“Applejack said something about a disaster happening at Sweer Apple Acres.” said Twilight.

“Well let’s do it to it!” said Sonic.

"I’m coming with you and maybe Rouge too.” said Rarity.

“Sounds interesting enough.” said Rouge. So Sonic and his friends new and old went to sweet apple acres.
