This race of robotic humanoids are 50-foot behemoths that eat any thing made entirely of metal which they use for fuel. Very little is known about them or where they come from except that they may be war mechs and are programmed to destroy everything in their path. They also can repair themselves if they are ever damaged, and have rockets within their feet which allow them to fly.
- The Iron Giant
- The movie's Signature edition features an exclusive seen where the Iron Giant has a dream in which he is marching with other metal giants like him throughout what remains of some city of an unknown planet, that they had presumably invaded and destroyed.
- It is possible that these bots don't really have genders of any kind.
