Steve (Voiced by C. Martin Crocker) is Dr. Weird's assistant. He has red hair and wears a lab coat. Every time, he's holding a test tube. Steve realizes Dr. Weird's crazyness but he stays his assistant through all the crazy times. during the duration of the tv series he has had his brain and spine removed. He has also been sexually harassed by animated corn, was frozen by a clown wig, and has ran out on Dr. Weird's experiments several times. Because the Dr. Weird skit before the show was discontinued, Steve's plot development did not go on until the movie of ATHF. Steve was later killed in the movie.
