Gallaxhar

Gallaxhar is the main antagonist of the 2009 Dreamworks movie Monsters vs Aliens.

He is a four-eyed, multi-limbed blue alien whose main goal is to retrieve a powerful cosmic substance called "Quantonium" from Susan, who was accidentally hit by an asteroid containing it and, in turn, grew huge due to it being a radioactive mineral. He lives in a huge UFO and utilizes many alien weapons, including giant, nearly-indestructible robots in his attack on earth. He also cloned himself to create a huge army to take over Earth. He was killed when his ship self-destructed.

He said himself that he destroyed his own home planet for no apparent reason but to test his weaponry.

In Ultima, Gallaxhar was recreated by Padro Lodo to serve as an alien commando of the Organization's alien armies.
