Anyone notice that GANTZ never shows the boss? Onion-Baby wasn't the boss, Dad was. Robo-Suit wasn't the boss, Big-Bird was. Gaurdian guys weren't the bosses, Multi-Arm was. Kei never made it to the boss on the Angel Alien's fight because the time ran out. Chuby wasn't the boss, Mom-Long Neck was. Who's to say Oni-Alien is the boss?
