Chuck is a minor character who appeared in the episode Crash Nebula. He is an alien chicken who has various weapons at his disposal.
Chuck is apparently disliked by most students at the Celestrial Academy, and thus, his only friends are fellow nerds, Sprig Speevak and Dif. He can become very angry when somebody mentions harming a turkey (e.g. cooking and/or eating one).
Chuck resembles a chicken in a robot suit. His suit is modified with things such as missiles and robot legs.
Chuck's only appearance was in Crash Nebula. The episode was planned to be the pilot episode of a spin-off series. However, Nickelodeon never picked up the series. As a result, Chuck (and all other characters who appeared in the episode) have never been seen since.
