Do you have a a favorite Gantz character?

Mine would have to be the dog that survived for so long. He didn't do much but he was precious. The other characters were just a bit out there. But on that episode when a grenade was put into the mouth of a older man with the string tied around the piece that would set it off being tied to female Kei who was being constant slashed by a antagonist. It was sad because she refused to run since she didn't want the man to die but it pained him so much that he moved his face to let the grenade go off so that she could get away. I can't remember his name but his optimism made him my second favorite. How about you
