Hero Meet-Up

It was a few days, the Ninjas were called to the Earth Protection Agency by Agent Bishop for an important mission.

"So what is up now, Bishop?" Raph said while crossing his arms. "Another Kraang invasion."

"We have been getting reports of strange aliens popping up all over a specific area." Bishop said before pointing at an image showing a small town called Bellwood. "You will go a secret location to get the details, then you'll be going here to investigate these sightings."

"Oooh a secret location!" Pinkie said in excitement. "I love those! They are so secrety!" But Raph was skeptical.

"So, how are we going to go to this secret location if we don't know..." But before he could finish, our heroes dissapeared in a beam of energy. Sometime later, they reappear in the secret location as Raph finishes to speak his peace. "Where It is?" He then looked around and found that our heroes are presently in a labratory. It was then that they met a 16 year old teenager who wore a black shirt that has a green stripe in the middle with a white 10 and green stripes on the sides of his shirt. He wears brown cargo pants with pockets at the knees and green and white shoes. On, his wrist, he also wore a device that resembled a wristwatch. Its faceplate was square had a white and green color scheme. The faceplate is black with two green stripes forming an outline for the hourglass.

"What's up?" He said. "Name's Ben 10."

"Hey, I've heard of you." Sunset said. "You're that hero that can turn into alien heroes, right?"

"Right on." Ben answered proudly. "Come on. I'll fill you in on what's going on in the next room." There, they meet Ben's Grandpa Max, a 66 year old man who wore a black shirt, covered by a red buttoned-up Hawaiian shirt with a floral design, white pants, and grey shoes with black at the bottom. The two of them then explained that warehouses are suddenly being built all over their town of Bellwood.

"And a warehouse is suddenly strange now?" Rarity said.

"No, that honor goes to what's going into the warehouse." Max said before showing a picture of someone taking 10 large cryochambers inside a warehouse, each one containing some strange thing inside. "And the people in charge." He then showed them a picture of strange people with uncomfortably big smiles taking the cryochambers inside.

"They don't look normal." Leo said "And they certainly don't look like any disguise made by the Kraang."

"Yeah, nothing could have a smile that unnatural." Pinkie said. "And I should now, I'm an expert on smiles."

"Now the rest of my team are down on the street gathering information, and we'll meet them once the teleporters recharged. In the meantime, I should tell you on how I got this." And as he explained, the images of the past appeared in his mind. "It all started back when I was 10 years old. I was on vacation with with Grandpa Max here and my cousin in my grandpa's RV and our first stop was in a natural park. I went for a walk alone, until he sees a what he thinks is a shooting star. The "star" is revealed to be the pod jettisoned from a space ship. It twists its trajectory and hones in on me and I barely manages to escape its destructive path. Edging closer to the crash site to get in a look, at what seems to me to be a satellite, I fell into the crater created from the impact. The pod opens itself to reveal to me a watch-like object with green circuitry: the Omnitrix. Surprising me, it latches itself onto my left wrist. After flailing with it, and multiple failed attempts to get it off, the faceplate emblem pops up and shows one silhouette of what we later know is of ten aliens. Thinking this is cool, I slowly pushes the faceplate back down and as time slows around me, as I transformed into the first of of my alien forms, all blanketed in a flash of green light. In this alien form, I screams and runs around in a panic, terrified to see myself on fire, but suddenly calms as I realized that I isn't in pain. I decides to test his power out, launching fireballs at the surrounding trees, ending in me accidentally creating a forest fire. Gwen and Max notice the smoke from the campsite. Thinking I may be in danger (and that I may be the cause), they both grab an extinguisher and rush to the scene in attempt to put an end to the fire, only for Gwen to stumble onto me, attempting to stomp out the fire, which is only making it worse. I tries to reason with her, only getting myself hit with the back end of the fire extinguisher; with Gwen spraying me with it and warning me to stay down. Setting her sneaker on fire, and getting a cheap laugh in the process after calling her a name, Gwen wass convinced it was really me. She asks what happened, and I spewed the whole story in a matter of seconds, finishing just as Max appears. He is just about to retell the story again, but Gwen interrupts and reminds us of the situation at hand. Max has an idea to get his grandson to start a new fire and let it burn into the old one in order to put them both out; it works, but most of the forest is destroyed just as the park rangers show up."

"So what's the name of you're first alien?" Applejack asked.

"I'll show you later." Ben answered before turning to two little grey guys with green eyes prepping the teleporter before turning around to give him a thumbs up. "For now, Blukic and Driba have gotten the teleporter ready to go. Shall we?" The group then stepped onto the teleporter and were teleported to the warehouse. Ben then activated the Omnitrix and transformed into a plasma-based life-form whose body is composed of a super hot inner plasma body covered by a dark red or brown volcanic rocks with the Omnitrix symbol on his chest. As a fire-based entity, his body radiates high amounts of heat. His feet have a slight oval-like design with only two toes and one back toe.

"This is Heatblast, the first alien I've ever used." Ben said. "In this form, I have immunity to heat, fire, magma, lava and cold, I can shoot fire from his hands, create large flaming rocks that can control and fly over, and absorb fire and heat. You could say, I'm totally hot." That joke made the group laugh quite a bit. "But back to the matter at hand. Team, are you in position?" At the west side of the warehouse, an alien with tall, with periwinkle-blue colored fur, black markings on his face, and pointed ears, with white in the middle of his face, his chest and his stomach, black stripes on his shoulders, waist, lower legs and lower arms, carrying a device that appears to be a blaster, colored indigo, white and orange on his shoulder and wearing very durable blue-and-black armor was standing next to a door.

"Rook Blonko, in position." He said. At the south side, a teenage boy with long black hair wearing a black shirt with the sleeves and collar roughly cut, a grey under shirt that has stripes and long-sleeves grey shirt that are slightly torn and blue holsters, pants that have a small tear below the left knee, and a padlock necklace marked with an "11" on it, with black marks around his eyes, making him appear tired, and a cross-shaped scar to his chin is instantly turning into metal by holding his hand to a metal wall.

He's accompanied by a dark blue creature that appears to be a cross between a dog and a dinosaur. She has red eyes, blue-gray spike-like hair running down from her collar to the tip of her tail, and black lines on her neck and legs, wearing a light blue collar with a gold bone-shaped dog tag.

"Kevin Levin and Zed, ready to go." He said. And at the east side of the ware house, a teenage girl with short orange hair with a blue hairclip wearing a light blue T-shirt with a cat logo on it, a blue plaid miniskirt and blue-tinted glasse, long white socks and blue sneakers with light blue stripes was honing some strange magic.

"Gwen here." She said. "Looks like the gang's all here."

"Looks like it." Heatblast said before turning to the ninjas. "All right then, let's do this." The ninjas all nodded before entering the warehouse. They then began to search the warehouse for those containers they saw on the pictures, meeting each member of Ben's team one by one. So far there there has been no sign of anything.

"It's Quiet...Too Quiet" Pinkie Pie said in a serious tone. "Always wanted to say that." Everyone groaned before seeing a strange glow eminating from behind a door at the end of a hall. They opened the door to see a room with 3 plexiglass containers, a small one containing 5 of those cryochambers, a medium sized on containing 48 of them, and 10 large ones containing 190 of them.

"Whoa!" Leo said. "That's creepy. Well, we better get started in letting these people out." But before Leo could open the first of the containers, alarms went off and a voice is heard by the intercom.

"Warning!" It said. "Warning! Pyronite DNA detected in containment area. All units apprehend and contain Pyronite."

"That doesn't sound good." Heatblast said. "But we can handle it." Soon, several robots came out to surround the heroes, only to be destroyed by the ninja's weapons, Heatblast's pyrokinesis, Rook's moves, Kevin and Zed's brawn, and Gwen's alien magic. The group had congradulated themselves for a job well done only for a moment before they started unloading the cryochambers. Unfortunatly, they only managed to get 5 of them out and teleport them back to base before the alarms went of again and the voice in the intercom was heard again.

"Warning!" It said. "Warning! containers compromised. Proceeding to containment relocation protocal."

"Wow, who ever build this place planned things out." Mikey said as rockets on the bottom of the container launched out of the warehouse and in seprerate directions to parts unknown.

"Well, that was unexpected." Twilight said before the alarms alarms went of once again and the voice in the intercom was heard one more time.

"Warning!" It said. "Warning! Warehouse selfdestruct in 30 seconds."

"Like I said." Mikey began. "This guy planned things out when he built this place." The group then ran out of the warehouse but not before the explosion made all of them pass out.

Ben Meets Jen

After 2 weeks of eternal darkness, Ben woke up in a hospital bed. The group was suprised to see that they had fully recovered from the blast.

"Glad to see you all finally up and about." Max said while sitting on a chair. "It has been 2 weeks."

"2 weeks?" Ben asked in shock. "We've been asleep for 2 weeks?"

"Yeah, you are actually the last one of us to wake up" Leo answered. "And Pinkie tends to walk in her sleep." At that moment Pinkie Pie walked in.

"Hey, Ben." Pinkie said. "I made this for you." She then put a cake next to Ben's bed, saying Get Well Soon.

"Thanks, Pinkie." Ben said. "So, what happened while we were out."

"No Idea." Twilight said. "Rook, Kevin and Gwen are already checking things out to see what we missed. We were hoping you could come with us to join them." Just then, Our heroes received a call from Rook

"Ben, Everyone, you need to come to our coordinates." He said. "Something just happened here." The group then arrived into a large crater.

"This seems frighteningly familliar." Ben said. Just then, a little green alien with warts on his face, eyes are on the side of his face similar to birds, and wearing a small black suit with silver armor had popped out of a crate.

"Are they gone?" He asked.

"Are who gone?" Sunset Shimmer asked. "And who are you?"

"Pakmar." The little alien answered. "This is my place. Was my place. Pakmar’s place!"

"Well, you’re safe now." Ben said.

"My hero." Pakmar said with little enthusiasm.

"Can we help?" Gwen asked.

"No." Pakmar said. "Just go away. I don’t want any more trouble."

"Yeah, I think it’s a little too late for that." Ben said.

"All I wanted was to run my toothbrush plaza in peace!" Pakmar said. "Now it’s in pieces."

"This is a toothbrush?" Rainbow Dash asked in amazment while holding something that looks like it should be going into the other end of a body.

"Eh, different aliens have different needs." Pakmar answered.

"Don’t even want to know." Raph said. "So, um, the guys that did this to your place were dissatisfied customers?"

"Hardly!" Pakmar said. "Some mob goons are shaking down us law-abiding businessmen. We pay them Taydenite, cash, gold, anything valuable, they "protect" us. Only thing is we don’t pay, they’re the ones we need the protecting from."

"Have they threatened anyone else?" Leo asked.

"Only every shop in Bellwood." Pakmar said. "Yeesh, kid! Where you guys been these past 2 weeks?!"

"Every shop in Bellwood, huh?" Ben asked. "I think I know I good place to start looking for them." It's them that they met with a local store keeper who wears glasses, a dark pink bow-tie and a light pink-striped yellow shirt with a dark pink apron and brown pants, has grown a little black mustache, and has a pot belly. "All right, Mr. Baumann. What do you know?"

"I know lots of things." Mr. Baumann said.

"Anything about an alien protection racket in Bellwood?" Casey Jones asked.

"Nope."

"So they haven’t been coming around here?" Raph asked.

"Who’s been coming around where?" Mr. Baumann asked.

"Right."

"Okay, then. Nice seeing you again, Ben." Mr. Baumann said. "Enjoy free gloppenbeef sandwiches to go."

"They’re on their way right now, aren’t they?" Rarity asked

"Look, it’s a simple arrangement." Mr. Baumann said. "I pay them, they leave. Which is what I want you to do right now."

"But, Mr. Baumann, I can stop them!" Gwen said

"No!" Mr. Baumann said sternly. "Every time a fight starts up in my shop, you people ruin it!"

"You think we're going to mess up your place more than they will?" Leo asked before thinking about what he said. "Okay, bad choise of words. What if me and my bros hide in the shadows, while everyone else just sits quietly at the counter? Then, well catch them by suprise."

"Fine, but no transformations unless it's necessary." Mr.Baumann said to Ben. The turtles then hide while the humans sit at the counter and eat their gloppenbeef sandwiches. Casey then notices a hooded figure several bottles of some fizzy alien beverage.

"Hey, could I have one of those?" The hooded figure then passed one of the bottles to him. "Aw, thanks! Uh, could you pass one of those to" And before he could answer, the hooded figure passed a bottle to Ben, Kevin, Gwen, Rook, Twilight, Sunset, Rainbow Dash, Applejack, Pinkie Pie, Fluttershy, Rarity, April, Karai and Shini. "Whoa! Uh, thanks." But before too long, a group of mobsters with mulit colored suits walked in.

"Ladies and gentlemen, may I have your attention." The leader said. "This is a matter of business between us and Baumann. If everyone leaves now, there'll be no problems."

"Yeah, would want a repeat of what happened at Pakmar's place." The biggest of the group said.

"I heard he has great deals on toothbrushes." Kevin said.

"I heard it was an accident." Mr.Baumann said.

"Accidents happen all the time." The leader said. "Preferably to people who are, in lack of a better phrase, lacking in funds, yesss." He and his goons then smiled wicked cruel smiles.

"Take it easy, now." Mr.Baumann said. "I don’t want any trouble." He then grabbed a box full of valuables, and as he began to search through the box, two of the goons noticed Karai sitting quietly.

"Whoa, check out the cute little build up on that one." A short one said.

"And those tiny little tootsies." a tall one said. "Yo, baby over here!"

"Ugh, male chauvinistic pigs." Karai said to herself.

"Oh, I like a girl who gives me the silent treatment, it makes me feel like their playing hard to get." The short mobster said before they were both called to attention by the leader.

"If you two are done, kindly collect our payment for me please." He said, causing the two of them to nod and rush over to the counter. The short one grabbed a piece of Taydenite from Mr.Baumann's hand, while the big one grabbed the box. "Pleasure doing business with you."

"Good." Raph said, catching the attention of the group. "Cause now the fun can begin."

"Oh, no, no, no, no, no, no." Mr.Baumann said.

"This doesn’t concern you, terrapins." The leader said before turning to the humans.

"Yeah?" Ben asked. "Cause from we're standing, it kinda does."

"Aww, looks like these youngsters needs to be taught a lesson manners." The leader said.

"Oh!" Donnie said. "Let me guess. You’re the one who’s gonna teach it to us."

"Not in my store!" Mr.Baumann pleaded. "Please I’ll pay you not to do this, Ben."

"Really?" Ben asked before getting back on track. "I mean, uh, your days of intimidating people are over, bubble brain!"

"Oh, I think not, my monoid friend." The leader said. "No, for you are about to have a rather intimidating moment right now. Terrorizers, biomnitize!"

"Biomnitize?" Casey asked. "What kinda battle cry is that?" Then, one by one, the mobsters seem to transform into aliens right before the eyes of our heroes.

"Gravabolt, biomnitize!" said the first one, who transformed into a large, hulking, bulky, broad-shouldered, reddish-brown alien with rocky skin, a giant mouth with teeth that are also made of rocks, and a molten lava planet core at the center of his body, covered in natural, yellow armor plating on his back, shoulders, and the backs of his arms. His feet are tan with three toes, and he has four claws on both of his hands.

"Snarepire, biomnitize!" said the second one, transforming into an alien composed of pale white bangages and decked out in egyptian duds that almost look transylvanian, flaps under his arms, which resemble the wings of a bat, crown-like golden spikes surrounding his eyes, a chin that is black with more green gaps and a golden beard-like spine jutting from it, an upper chest and shoulders that are covered by a large collar/wrap-like garment with green and black stripes, and black-and-gold pads on each shoulder, with each one having a green "eye" on them.

"Frankenfrag, biomnitize!" Said the third one, who turned into a humanoid frog-like alien with three-fingered hands, a muscular body with a human nose, black hair with sideburns, skin that has several uneven seams, combining grayish-yellow with darker grey, a pair of bolts on each side of his neck that are green in the crease, metal pants with lines on them with glowing green triangle dashes in the middle, a belt that is green with white stripes and bolts in them, one of these bolts being a buckle, turrets that are green with screws on them, coils that are white and feature green bulbs at the tips, pants that are a greenish-black color, "boots" are copper with three green slits in them, two tower-shaped conductor coil-like generators on his back that look like they are metallic-organic growths.

"Jury Ditt, biomnitize!" Said the fourth one, who turned into an alien who bears a close resemblance to a goblin, small in stature, only about as big as a human head. He has white skin, a big nose, a black and white head and face, black shoulders, large hands with four digits and feet which are merely stubs. Ditto also has three red spiked fin-like growths on his head, and gem-like extended sensory nodes on his arms and waist, wearing an aviator's outfit which comes with an ascot. also has a spike on his chin and one near each of his eyes.

"Bloxxworks, biomnitize!" said the fifth one, who turned into a a robot-like alien with skin that is made of red, yellow and blue metal, with black stripe, studs all over his body, feet that are stubs, hands that are extremely large to balance most of his body, a transparent piece of green glass on his chest, revealing the gears inside of him, a key on the top of his head,.

"NRBlast, biomnitize!" Said the sixth one, who turned into an alien similar to Heatblast, except he's covered in heavy, dark green-teal oven-like with three slits where his eyes should be.

"Humungoujaws, biomnitize!" Said the seventh one, who turned into a somewhat humanoid dinosaur alien that shares a number of traits with Earth's aquatic life, such as an alligator, an eel, an anglerfish, and a shark. He can change between a fishtail with triangular lines or legs at will and has a phosphorescent light on his head, wearing a green and black sash across his chest, going from his right shoulder to the left side of his lower back.

"Ghostgrade, biomnitize!" Said the eighth one, who transformed into a ghost-like alien with a gaseous appearance and claw-like hands, and greenish white skin with black lines running all over him, a torso that's black with greenish white lines running all over him, and a green eye in the center of his head.

"Chamungousaur, biomnitize!" said the leader, who turned into a humanoid dinosaur alien like Humungoujaws, but with purple skin like Cham-Eye-lian's with three eyes, one red, one green, and one blue, a tail, and claws.

"Whoa, nelly." Applejack said.

"Still think you can take us on?" Humungoujaws asked.

"Yeah, we kinda do." Ben said before activating his Omnitrix. "Some of you may be bigger then us, but we still out number you, ever more so with Echo Echo." He then pushed the button that begins the transformation, but instead of Echo Echo, he's transformed into an alien that resembles a humanoid opossum mixed with a porcupine with black quills for his hair and more on his back, gray quills all over the rest of his body and a tail that is long like a rat's tail, wearing a black, white, and green shirt with pants, gloves that are black and fingerless, with his Omnitrix symbol located on his lower stomach.

"Uh, Ben?" Kevin asked in confusion. "Did you scan Argit when we last met him? Cause it kinda looks like to turned into him."

"Yikes!" Ben said in shock. "This is embarressing. Must have activated a new playlist on the Omnitrix. Oh well, at least I know what this guy can do. Turtles, duck!" He then fired quills that punctured the eight alien hybrids, causing them to collaps on the ground. But Chamunousaur dodged the quills and dissapeared. Mr.Baumann cowered behind the counter, impressed at the little damage done.

"I'm impressed." He said. "Normally, there's a lot of damage everytime he walked into my store." The heroes had held there own against this strange alien hybrid, until he pulled out a gadget that caused Ben to revert to normal, much to the suprise of eveyone.

"How'd you do that?" Ben asked in shock.

"That's for me to know, and you to find out." Chamungousaur said before knocking everyone else in a pile. He and his gang, who just got up on began to leave.

"Isn’t this where one of us does something amazing to save the day?" Kevin asked. The hooded figure then looked at a clock on the wall.

"Why, yes it is." She said before activaved what looked like Heatblast, only more slender looking with an omnitrix that looks cat-like, and rush into action.

"Oh, not another one!" Mr.Baumann said. "Just when I thought this would be a good day." The female pyronite flew past the hybrid mobsters and kicked the box back to the counter before blasting the goons out of the shop. She then brushed her shoulders off and turned to the group with shocked looks on their faces.

"Who are you?" Ben asked, the most shocked of them all.

"Flambella." The stranger answered. "I also go by Jen 10, which is short for Jennifer Tennyson."

"Tennyson?" Ben asked, even more confused. The stranger then turned to a 10 year old girl with brown hair, green eyes, a lime green and white shirt that had a cat with the number 10 on it, black pants, sneakers, and a hair clip.

"I'm your sister, you big lug." Jen said, making the entire group completely stunned now.

Jen's Story

After leaving Mr.Baumann's shop, the team were all riding Rook's truck, with Jen sitting at the far end all by with Spike and Fugitoid keeping her company. Everyone was rather quiet about this Jen 10 being Ben's sister. Rook decided to break the silence.

"I am curious." He said to Ben. "You never told us you had a sister."

"Because I didn't know about it!" Ben replied. "But i'm going to learn more about it." It was then that our heroes soon arrived at their destination, Ben's house. There, a woman with fair skin, green eyes, and blonde hair, wearing a light green sweater over a white shirt, tan capris, and white flats was outside, waiting for them. Ben then got out of the truck to meet her.

"Hello, Ben." She said. "I got your message. You have questions?"

"Yeah, like why you didn't tell me I had a sister, Mom?" Ben said. "When did this happen, and how did she get an Omnitrix?" Ben's mother sighed and motioned to him to come inside and sit down on the couch.

"It all started back when you were 10 years old. “ She began. “Your father and I were planning on telling you when you returned, but then you called and told us that you would be traveling with your Grandpa Max for one more year. So we thought of introducing you to Jen when she was born, as a surprise. But then a strange little gray man showed up and said that he would like to train Jen to be a hero and an ambassador. Your father was hesitant at first, but when he mentioned you and all the enemies that would like to get to you through us, I thought it would be best. So when the time came for Jen to be born, the little gray man helped with the delivery, which went much smoother than it went with you. Your father was still against the idea of Jen risking her life, but I wasn’t. I knew that Jen would need to protect herself against whatever came her way. So while your father was still working, I would help Jen with her training. By the time she was 1 year old, she was able to walk upright without falling, which amazing me, even more so when she said her first words when she was 3. When she turned 5 years old, she was given a device the little man called an Omnitrix, which is the tool that she would use for her diplomatic missions. I was proud of what Jen had become, but your father didn’t think that way. He said that I was putting her in danger by letting her do this, which caused us to fight a for years, even more so when we found out you had an Omnitrix too. Well, one day, after you told us about how you prevented that Maltruant guy from reshaping the universe in his image, your father said he had had enough, and the 2 of us got divorced.”

“So, dad left?” Ben asked in shock. “Just like that? He didn’t take anything?”

“Just the car and a few of his things.” His mom answered.

“Why didn’t you tell me about all this sooner?” Ben asked.

“I didn’t want you to get upset about it.” His mom answered. “With you being famous and all, I didn’t wan’t your personal life to interfere with your celebrity life. I’m sorry.”

“That’s okay.” Ben said. “I’m not mad, just surprised with everything you said.”

“Look, all I ask is that you accept Jen as your sister and your teammates.” Ben’s mom said. “Can you promise me that?” Ben thought long and hard on this, considering everything that has happened to her family while she has been saving the galaxy. She didn’t want to tear it up anymore than it is already. So he knew right there and then what to say.

“Okay, mom.” He said with love in his heart. “I promise.” The two of them then hugged it out a lot.
