Actually, from what I've read, he's supposed to be introduced as a new male lead in the show, like robin and superboy. There is also supposed to be a new female lead introduced along with artemis and miss martian. Speculation points to the new lead being wonder girl. According to what I've read, they wanted to use her from the beginning, but were not able to because of legal issues, but they have cleared that up, so look for her to join the group as well.
