A/N: THIS WAS NOT MADE BY ME!

My friend Monica wrote this... and has gracously let me upload it. I love this so much, it's so funny! XD

I don't think that I'm gonna upload any more of this stuff... so... don't expect anymore Ben 10/Gen. Rex stuff anymore.

Rex felt solitary. He was alone in his room on a Saturday morning, well, what he counted as a room. It was a bus that was made into a room. There was the table at the back, his bunk beds were the seats on the side, he had a tv across from him, the doors to enter. Outside of the bus was a gigantic room, probably made for a gymnasium.

Rex Salazar is his name. He doesn't remember his parents, he found his brother, Caesar (sez-are), and is stuck with a life he has never asked for. He always felt bewildered when he tried to figure out his past life. All he remembered was waking up and seeing Six's face.

There was a knock at the door to his room. Rex tried to open it but couldn't. There was a laugh outside. He knew right away it was Bobo. Bobo was his talking chimpanzee friend. He had a lot of tricks up his sleeve and almost always got away with them.

"Ugh, Bobo that's enough," Rex shouted, "open the door right now!"

Bobo opened the door, and sure enough there was a big, purple ultimate spider-monkey growling at him. Rex was so myopic that it threw him back in a terrified shriek. It was Ben Tennyson with Bobo on his back with a camera. They both were laughing really hard. Rex was embarrassed. Bobo had pulled a prank on him. He was just glad Bobo wasn't trying to get him to go on another escapade.

"That was not funny," Rex said when he pulled out his smack hands. "You've got your omnitrix, I've got my nanites."

Ben and Bobo looked at each other and then ran out of the bus/bedroom. Rex put them away and ran after them. He always thought it was really weird. Ben has a watch that can turn him into a thousand aliens, and he's got nanites that he can tell them what to do, like making giant metal hands or boots, or a sword that turn into a chainsaw, and so much more. He didn't know where Ben got his watch and he didn't really know how he got his powers. Neither the omnitrix nor his own powers over nanites were innate abilities. Rex, however, did not care. He wanted to go after Bobo and get revenge on Ben... but only after he threw Bobo in Breach's pocket-dimension.
