General Rogard

General Rogard is the military leader, and an anti hero of The Iron Giant. He is Kent Mansley's boss and despises him for his paranoia, and even blames him for "blowing millions of Uncle Sam's dollars out of his butt." In spite of this, he leads the attack on the Giant, but only after Mansley manipulates him. He reforms when Mansley launches the missile into the empty sky. After a heated struggle, Mansley tries to drive away, but the Giant crashes him, allowing Rogard to have his soldiers arrest Mansley. He acknowledges the Giant's sacrifice and tells the army "let's go home."

Trivia

 * He is commonly mistaken as the main antagonist. However, Mansley is the main antagonist since Rogard only makes a few appearances throughout the movie. Plus, Mansley had bigger plans than anyone else.
