Film: The Day the Earth Stood Still (1951)
Location: Civilized area
Height/Weight: Slightly Larger than the Average Human
Affiliation: Neutral, leaning on good
Summary: Sometimes, the supreme alien race is more scared of us than we are of them. And they will take drastic measures to ensure that we don't do anything reckless. The best option is sometimes just to say, "we can do it better". This was the mindset of whatever intelligence created the almost God-like robotic sentinel known as Gort.
History: Gort was created by an alien race that almost exactly looked like our own. Both the robot and an alien ambassador named Klaatu came to Earth with an offering of enlightenment and peace, but the trigger-happy planet only complicated matters. For Klaatu's kind had worried that the newfound atomic power in Earth's hands would spell doom for themselves and the galaxy at large, and Klaatu's plan B in case of diplomatic failure was allowing Gort to destroy the world.
Notable Kills: Nothing special.
Final Fate: A human friend of a dying Klaatu manages to give Gort the failsafe before he can destroy everything. After resurrecting his friend, Gort and Klaatu leave Earth, with the latter warning the planet that they won't be so forgiving if it continues to be violent.
Powers/Abilities: Gort is pretty much unstoppable. Nothing can penetrate him, he can vaporize anything with his eye laser, and it is strongly implied that he could reduce all of the planet to nothingness at the drop of a hat.
Weakness: If there is one way to get Gort to change his mind about blowing things up, it's telling him these exact words: "Klaatu Barada Nikto". It is unknown as to what these words exactly mean in english, but there are a number of theories out there.
Scariness Factor: 4.5-Gort is literally the textbook definition of a Deus ex Machina. Were it not for the fact that Klaatu had a firm grip on him, he could destroy the entire galaxy as we know it.
Trivia: -In case the metaphor isn't obvious enough, just pretend Klaatu is Jesus Christ. His story makes much more sense now, doesn't it?
-The iconic main theme of the film was composed by Bernard Herrmann.
