Gallaxhar

"Humans of Earth, I come in peace. You need not fear me, I mean you no harm. However, it is important to note that most of you will not survive the next 24 hours. The few of you that do survive will be enslaved and experimented upon. You should, in no way, take any of this personally. It's just business. So to recap, I come in peace, I mean you no harm, and you all will die. Gallaxhar out."

- Gallaxhar Gallaxhar is the main antagonist of the 2009 DreamWorks film, Monsters vs. Aliens. He is voiced by Rainn Wilson.

In the film
He is the leader of the invading alien force trying to take over Earth. In the past he destroyed his home planet. He is awoken from his cryogenic sleep when his computer detects Quantonium on Earth. Gallaxhar then sends a Robot Probe to extract and bring it to him. When the monsters defeat his probe, he almost sends another probe, but his computer tells him that the "carbon-based lifeform" (Ginormica) is now too strong, and that the Quantonium can not be retrieved by a Robot.

He comes to Earth and sends a message to the citizens of Earth, then captures Ginormica, and in the process blasts Insectosaurus with his ship's phasoid cannon.

When Ginormica is on board the ship, she frees herself, Gallaxhar then flees to his Extraction Chamber where he gets the Quantonium out of Ginormica. He succeeds and clones himself for times. This is enough for him to create an evil clone army of himself.

After Dr. Cockroach destroys his computer by stepping on the color buttons in the correct order while dancing, the self destruct system sounds. He attempts to escape, but once again is forced into combat with Ginormica. She then gets her Quantonium back and escapes on Insectosaurus (who is now a butterfly). Gallaxhar tries to escape in an escape-pod, but fails and is killed in the explosion of his ship.

Trivia

 * Gallaxhar has the highest body count in dreamworks animations since he obliterated an entire planet and used a giant robot that possibly killed thousands.
