Films: The Day the Earth Stood Still (2008)

Alias: Genetically Organized Robotic Technology

Type: Alien

Location: Civilized Area

Height/Weight: That of a small building, but the swarm graduates to that of a football field.

Affiliation: Neutral, leaning on Evil

Summary: More than fifty years ago, the world was met with an ultimatum to stop being a place of war and violence lest we all face the consequences. Now, it's happening again, only crazier and a bit less hopeful than before.

History: For some time, some very human-like aliens have come to our planet in order to judge whether humanity deserves to live or die. In the modern day, one alien arrives in a massive sphere of energy, only to be shot for looking weird. It is Klaatu, and he's brought with him the massive robot known as GORT. But even as Klaatu sees all the ups and downs of mankind, GORT is not so forgiving, and after being imprisoned, his true powers are about to come into the light...

Notable Kills: His true form is a swarm of nanomachine locusts that eat all things metal...and whatever might be around said metal.

Final Fate: After GORT turns into a massive nanomachine swarm, Klaatu manages to disable it just in time before it can claim humanity. However, while the alien threat is over, the Earth has lost all of its electricity. Thanks for putting us into the Dark Ages again, aliens!

Powers/Abilities: GORT is unstoppable, and can fire multiple beams of pure energy at targets. But when push comes to shove, it can disperse into thousands of self-replicating nanomachines that can eat through metal in seconds.

Weakness: Klaatu can stop GORT with the phrase. You know the one. But the swarm can only be stopped by direct controls in the sphere whence it came.

Scariness Factor: 4-The CGI isn't exactly the most convincing...but GORT is stronger than ever. Not only can he destroy more things at once, but we heavily doubt that anyone saw that whole "turn into a bunch of duplicating robo-locusts" thing coming. Needless to say, GORT is pretty much doomsday in one package.

Trivia: -Klaatu was played by Keanu Reeves, who absolutely adored the original film, and was insistent that his character's famous phrase remain, despite the filmmakers wanting it out for no reason.

-While the original film promoted anti-war, this film is more on the eco-friendly side of things, which sadly removes a lot of the original's impact and ambiguity. Also, that ending. Ludd wasn't right, you know!
