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 DreamWorks' 18th full-length animated feature film Monsters vs. Aliens. He is a squid-like alien life-form and the traitorous leader of the invading alien force trying to take over Earth.

He was voiced by Rainn Wilson, who also played Gargamel in Smurfs: The Lost Village.

Role in the film
In the past, Gallaxhar destroyed his home planet for seemingly no reason and escaped on his ship, putting himself into cryogenic sleep. 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 life-form" (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 and Gallaxhar flees to his Extraction Chamber where he successfully gets the Quantonium out of Ginormica. He then uses the Quantonium to clone himself four times, this being enough 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 by the explosion of his ship.

Personality
Gallaxhar is truly egocentric, intelligent, manipulative and domineering. He is portrayed as the ruthless, oppressive, and totalitarian dictator. Sometimes, Gallaxhar can get into arguments with the Computer. One of his most unmerciful and objectionable plans is when he tries to eliminate all life on Earth in order to repopulate it.

Trivia

 * Gallaxhar has the highest body count out of any DreamWorks villain, since he obliterated an entire planet and used a giant robot that possibly killed thousands.
