"Don't call him a puppet! That's an offensive term!"
— Robbie defending Rex against Cat in Pilot.
Rebbie is the pairing of Rex Powers and Robbie Shapiro (Re/x and Ro/bbie). Even though Rex is a puppet and Robbie should have control over him, it mostly seems like Rex has more control of Robbie by bossing him around and arguing with him a lot. However, they also can get along with each other and show that they are really close friends at times. Rex also likes to give false information to Robbie to have him look foolish and then make fun of him later on. For example on Beggin' on Your Knees, Rex told him that Ryder has his ears pierced, when he knew Robbie wanted to be like him to get girls, though it was not true.

According to Rex's profile on TheSlap, he hangs out with Robbie mostly because he feels sorry for him.
