Get the Ack hill billimug. The entity of evil in halo 3. Feared by most people who are unfortunate enough to come in contact with him. If your lucky enough to have him on your team stand back and watch the blood fest. If your fighting him your already dead. Every 2 out 10 times someone sends him a friend request they get the red rings of death. He is able to perform crazy, impossible, and inexplicable feats without hacking. believed by some to be: Chuck Noris, Bill Gates, the super devil, or Chuck Noris possessed by the super devil.
