Terra

The Titans meet a girl named Terra who is a difter. She has the powers to move and control Earth. They allow her to stay at Titans Tower while they wonder if she should become part of them. Beast Boy convices her to stay, and he finds out that she is unable to control her powers. She makes him swear never to tell anyone. She then beats Cyborg in practice. They all go to fight Slade and Terra has a face-to-face talk with him. She is told that he can teach her to control her powers. She soon ultimately loses control of he powers and creates a twister. Beast Boy helps her and she begs for him to never tell. The Titans invite her to be a Titan, but Robin tells her, he knows her secret and she runs away, Slade watching her every move.
