Chapter 1: Ben meets Jen 10!

Sixteen year old Ben Tennyson couldn't believe his luck.

He was fighting the Forever Knights (for the fifth time that week) with Gwen and Kevin at an abandoned factory. All he had to do was change into Humungousaur and plowed through all their defenses, Gwen used her mana powers, and Kevin absorbed a sword and started slicing everywhere. The Knights were beaten and had started to run out.

So far, so good.

"Well they gave up easily today." Ben commented, changing back into himself.

"Yeah almost too easy." His cousin Gwen noticed.

"Either way, we can finally go see what this whole mess was about in the first place." Kevin said, walking down the hallway.

The other two followed. The factory held no importance; it was once a manufacture for mirrors. Apparently, the Knights were looking for a certain kind of mirror if the whole factory was swarming with them.

"I don't get it, why would the Knights need a mirror?" Ben thought aloud.

"Maybe to power some super powerful weapon or something?" Kevin replied.

"I doubt it; they probably have some other uses for this mirror." Gwen put out.

Ben shrugged his shoulders. He didn't care particularly care about some powerful mirror since he already had the most powerful thing in the universe on his arm.

Yes Ben Tennyson the wielder of the Omnitrix which gave him the power to modify his own genetic code in order to turn into various alien creatures. Originally when he was ten, he had just 10 aliens in his disposal, but gained more as he grew older. He would have even more in the future to come though.

Team 10 stopped walking, standing in front of the door labeled Do Not Enter!

"Well this must be the right place." Kevin joked.

"It says do not enter, gee I wonder why?" Ben said sarcastically. Kevin glared at him.

"Come on, let's just open the door." Gwen interjected before the boys could start arguing.

Kevin nodded and absorbed the door. The material went into him as he punched it down.

Ben and Gwen entered, looking around for anything important.

"Are you sure a powerful mirror lives here?" Ben asked Gwen.

"Well yeah, I mean, why else would we be in here." Gwen said, charging up her mana so they could see.

Almost immediately, a mirror glinted from the light. They all turned to see a tall mirror hanging from the wall. It had a silver rim and it showed no reflection.

"Well I guess is the part where we see who the fairest of us all is." Ben said, walking near it.

"This is the thing the Forever Knights wanted to steal?" Kevin said, looking incredulity at it.

"Yeah it looks like some normal mirror." Ben touched the surface and what he saw made him draw back. "Uh…guys you might want to see this."

Kevin and Gwen walked over and gasped.

In the reflection of the mirror was Ben…but then again it wasn't. Ben didn't have a curvaceous body and brown hair in a ponytail. The mirror Ben had a green, black and white shirt, but she wore black shorts. The other noticeable thing was that she didn't wear a jacket.

"Woah dude, this mirror changed your gender." Kevin snorted. Ben gave him an annoyed look and gazed back at the mirror. Mirror Ben gazed back at him.

"This is unreal, a female Ben?" Gwen sputtered.

Curious, Ben reached out farther at the mirror. Female Ben followed suit.

ZZAP!

"Ouch!" They both exclaimed, both of them drawing back their hands. They looked at each other in surprise.

"Did you just talk!?" They both shouted.

"Hey stop copying me!"

"This isn't funny!"

Kevin was rolling on the floor, tears coming down his face.

"Oh man, Tennyson One and Tennyson Two are both funny!" He said through his laughter. Gwen gave him a terrible glare before turning back to the mirror.

"Okay so we know you talk, but who are you?" She asked.

"The name's Jen, nice to me you." The girl replied.

"Jen, Jen Tennyson?" Ben asked, excitement dancing in his eyes.

Jen nodded and raised an eyebrow. "Yeah why?"

"My name's Ben, Ben Tennyson."

"No way, that's not scientifically possible, you're not scientifically possible." She pointed at him. "I'm the only hero that saves the universe."

"Well I saved the universe many times in my life too. It was all thanks to the Omnitrix."

"Omnitrix? What's that?"

Ben held up his wrist and showed her the watch. "This is the Omnitrix, it stores-"

"The DNA of all the aliens in the galaxy!" Jen interrupted.

"You know about it?" Kevin finally stopped talking and glared at Jen.

Jen bit her lip and fidgeted nervously. "I sorta have something similar to that."

"Really can we see it?" Ben asked her.

Jen twirled her ponytail. "Well…um..ya see…I kinda lost it."

It was so quiet that you could hear a pin drop. Ben's jaw went slack as did Kevin's. Gwen shook her head.

"You mean to tell us that Ben's alternate female counterpart lost her version of the Omnitrix?" Gwen practically yelled.

Jen yelped and blushed a bit. "I didn't lose it! It's just…oh I can't explain it!"

Ben recovered from his shock and sighed. "Jen maybe we can help you find your Omnitrix."

Jen's face lit up. "You mean it?"

"Sure, if I'd lost the Omnitrix I would want help right away." Ben said.

Jen felt her face turn red at that. A boy whom she just met offered to help her find the artifact that could re-shape the whole universe.

No! He's my alternate universe counterpart! I can't fall in love with myself!

Or can I?

"Thank you Ben! I wonder if there's a way to bring you to my universe."

"Maybe if we shoot a powerful beam at the mirror, the rippling could create a hole in space and time." Kevin said.

"Already on it!" Ben turned the dial and found the alien he was looking for. He slammed it down and a flash of green light filled the room. Ben had changed into a silicon based alien made of extremely durable crystal. His body is overall purple, with several dark lines and spots. His hands and face are magenta, and he also sports six magenta shards on his back, two on his chest, and one on the top of his head that resembles a horn. His face consists of a mouth and one large green eye at the center.

"CHROMASTONE!" He exclaimed.

"You might want to stand back Jen." Gwen told the girl.

Jen nodded and took a tentative step back. Chromastone charged his beam and fired a multicolored beam at the mirror. The surface rippled until a hole appeared in on the surface.

""Go on you guys, I'll go in afterwards." He told Gwen and Kevin.

They ran into the portal and as they did, Chromastone jumped in after them. The hole closed up, sealing for good.

"Well there goes our way home." Kevin said.

A flash of green signaled Ben turning back to normal. They all turned towards Jen who was grinning from ear to ear.

"You guys sure know how to make an entrance." She said.

"Well we are Team 10 after all." Ben quipped.

Jen giggled and lightly punched him on the arm. "Come on, I might as well show you around."

"So why were you in the factory?" Kevin decided to ask.

"I and my team were investigating a break in from the Eternal Gladiators who were trying to steal the mirrors to power their doomsday device."

"Your team, like an alternate version of us?" Gwen pondered aloud.

"If you mean my dorky cousin Glen and his girlfriend Kylie, then yes."

"This is going to be an interesting adventure." Ben said.

I'm ending the chapter here. Next time: Meet Team 10 Alternative!
