2261. Gallaxhar

Rainn Wilson as Gallaxhar, an evil alien overlord who hopes to take over Earth. He is served by gigantic robot probes (around the same size as Insectosaurus) and possesses a giant cloning machine. He claims to have suffered several traumas in his youth, driving him to destroy his own homeworld, and plans to make a new one on Earth - although viewers never hear most of the story. He aims to collect quantonium - the substance that transformed Susan - to give his cloning machine enough power to generate an army of clones of himself to conquer Earth, and is determined to extract it from Susan. Gallaxhar serves as the main antagonist of the film.
