A character on the T.V. show "Teen Titans" and the comic series. He is mute (That is, unable to speak or make basically any noise with his vocal cords), and his comic past canon states he is the son of Slade and Adeline Wilson. In the show however nothing was confirmed of this, although not denied either.
"Jericho, isn't he that blonde kid from the Teen Titans?"
"Yeah, he appeared in Season Five."
