Second minecraft Mob character Ace the Skeleton. He hates pretty much everyone, and if anyone, Player, mob, or other skeletons, hit him he will fill them up with holes so fast a sword will never reach him.

He claims he and his family own the lands and wont let people do as they please, his biggest targets being the player who destroys the land just to make fake shelter and needed structures and creepers, especially Atom who wish nothing more than to see the land filled with holes.

You'll be lucky if I aim for the head -Ace
