Rex ran towards Big Chill, going to punch it, but as soon as he got to it, he just slid right through it.

"What?" Rex asked after sliding to a stop behind the creature.

"You're an alien, too?" Ben asked.

"Alien?" Rex pulled the Smack Hands back in. "You've got some messed up mind, E.V.O." He pulled out the BFS and charged at Big Chill again. But this time, something strange and unexpected happened. It pressed what looked to Rex an hourglass in the middle of it's chest and it turned into something else. To Rex, it looked like a huge dinosaur. As it finished changing, it yelled to the heavens.

"Humungousaur!" it yelled.

Rex, completely caught off guard, ran right into it and staggered back, pulling the BFS back in.

"Don't mess with me!" Humungousaur yelled, getting bigger and bigger until it's head touched the ceiling.

"You're gonna learn not to mess with me!" Rex pulled out the Slam Cannon and made a good couple shots right into the chest of Humungousaur. Each shot made him stagger back a bit.

"That all you got?" it growled and began to charge Rex.

Before it got too far, it was stopped by a large, pink circle.

"Ben, don't!" Rex looked over and saw Gwen and someone completely white, but it looked like Kevin.

"Don't go picking fights, now, kid," Kevin sighed.

The monster pressed the button on it's chest again and turned into Ben. "He started it!" he whined.

"Uh, what?" Rex asked. "How did-Why-What?"

"Long story," Gwen sighed, rubbing her forehead.

By then, Rex had just noticed Six had his swords out, seemingly ready to join the short fight. Rex decided to leave the group of freaks and stood by Six.

"You said something about aliens," Holiday, of course intrigued by all this, went up to the group of teens. "Could you explain that to me?"

"You mean you really don't know?" Kevin asked.

"And you really can't recognize me?" Ben pointed to his face.

Holiday shook her head.

"Then I guess we are in a different world," Ben sighed and leaned his back against a counter.

Holiday went and picked up her sample of the "Juice."

"I guess this stuff really is powerful, if it enabled Breach to pull from a different dimension," Holiday started talking to herself.

"So, who is this Breach person?" Gwen asked.

"She works for our worst enemy," Rex chimed in using arm movements for emphasis. "She creates portals and has her own little creepy pocket dimension, which she trapped me in once. She's kinda insane."

"Is she one of those…what did you call me?" Ben asked. "And Ebo?"

"E.V.O," Six corrected him.

"And yes," Holiday continued, setting her sample down on the counter Ben was leaning against. "Rex told you about nanites. Usually, they're inactive and harmless to a human. But, sometimes, they activate, causing mutations in the person."

"Or plant. Or animal," Rex said, walking towards the counter, but staying a safe distance away from Ben. "They're in every living thing. Even deep in the ocean."

"Van Kleiss, our enemy, he's an E.V.O. too," Holiday continued. "So are all his lackeys."

"If you ask me," Rex was now behind the counter Ben was leaning against, "they're all creepy."

"The reason we were at the lab you came through to our world in is because he was there trying to get something called 'Juice.'"

"This stuff," Rex picked up Holiday's sample.

"It's supposed to amplify the powers of an E.V.O. well past impossibly strong," Holiday was starting to get irritated at Rex for interrupting her so much.

Rex sniffed the sample. "This stuff smells nasty," he commented, wrinkling his nose and putting it down.

"How about you explain your story now?" Six asked.

"Well," Ben stood up, "in our world, we are what are called Plumbers."

"Who are like the cops of the universe," Kevin shrugged.

"Yeah, 'cause there are aliens who like to cause trouble and we have to stop 'em."

"Most of the plumbers," Gwen continued the explanation, "like Kevin and I, are aliens. Kevin is an Osmosian and I am an Anodite. Ben is human," she pointed to Ben.

"But, this watch," Ben pointed to it, "called the Ultimatrix, enables me to turn into various aliens."

"So, mutants and aliens," Rex laughed. "Sweet combination!"

"So, what can you two do?" Holiday went up to Kevin and Gwen.

"I can manipulate energy from my aura to create practically anything," Gwen said. "But, it's not invincible. Some things can break it."

"And I can absorb the energy of anything I touch," Kevin sighed, turning his normal color again. "And I can use it for anything."

"Fascinating," Holiday started pacin.

"This really fascinates you, doesn't it, Doc?" Rex leaned against the counter, too.

Gwen now walked over and observed the Juice sample. "So, do you know if this Van Kleiss has any of this Juice?"

"Probably," Six said.

"Yeah, we kinda lost track of him when you guys came along and, I don't know…hit me with your car!" Rex said.

"Well, you were in our way," Kevin stated. "And you chipped the paint."

"You slammed me into the wall."

"Don't fight!" Gwen sighed. "I thought we were past all this."

"I wouldn't mind a round two," Ben and Rex said in unison.

"If you wouldn't mind getting back on subject," White Knight snapped in a way that startled Ben. He reacted by flinching back and slamming the Juice sample backwards, causing it to crash on Rex's face. He fell onto the floor.

"Rex!" Holiday rushed to help him.

"Crap!" Ben, for the first time, sounded worried.

"What did you do now?" Kevin sighed.

"I-I didn't mean to!"
