Timmy was a minor villain who appeared in the Mystery Science 3000 episode, "Fire Maidens from Space". He is an evil doppleganger of Crow T. Robot, one of the show main characters.
He is a dark spectre from deep space who takes on a form to look like an all-black verison of Crow ("Timmy" was portrayed by the all-black "Crow" puppet used in the theater segments) after the robot "prays for a friend". Timmy causes trouble for Crow's shipmates and is eventually ejected off the Sallette of Love. At the end of the episode he is found by the villians in Deep 13 and causes trouble for them.
