This guy is the exact opposite of Andrew Ryan/GLaDOS/etc., which is exactly what makes him so horrible: a cold, emotionless demon with
no motives whatsoever other than to brutally murder you. He's huge, he's fast, he's intimidating, and he's got a freaking rocket launcher welded on to his arm! He's not exactly stealthy, but who needs stealth when on Ultra Violence (the MANLY difficulty) a direct hit is an instant kill. You know what? That makes him even more fun. He's a real challenge, but an extremely fun challenge as well.
It's 10,000 lbs of pure rage with a rocket launcher arm stomping after you at 20 miles per hour, and it's freaking awesome.
