X

"X" is the name of the Xilien leader in the 2004 Godzilla film Godzilla: Final Wars.

Overview
X has a strong connection to Gigan, being able to re-awaken him after mummification for over one thousand years. X identifies himself as a "Kaiser" one of the few beings with M-base in their DNA, making him one of the most powerful beings in the universe, should he tap into his potential. He, like all M-base carriers, is an adept fighter, and carries leadership ability, as he becomes the undisputed leader of the Xilien race.

Name
X is simply a name that X chose for himself, as he felt that his real name would be too hard for the humans to pronounce. the letter "X" was chosen because he believed that it captured his personality, considering himself mysterious, and his being from space.

Career
X became leader of the Xiliens after killing his superior. from the start X did not believe in a peaceful and slow invasion, and saw better to wipe out the humans, save for a select few, and harvest their mitochondria, instead of keeping most of the humans alive.

Mental status
X appears to be mentally unstable, as he feels no remorse in killing his superior, the leader of the Xiliens, who is presumably his mentor. X is prone to untimely fits of hysterical laughter, like when one of his monsters is defeated, when Godzilla is released, or when he is beaten in hand to hand combat by Shinichi Ozaki. X is also victim to violent outbursts of rage. he becomes very angry when, one of his monsters is defeated, or when he is outsmarted by one of the humans.
