Part of the infamus trio from Metropolis Zone from Sonic 2 which every oldschool Sonic fan hates!XD My favorite/worst one has to be Shell Cracker. Sure the other ones are down right annoying, but I just find this one more intimidating since he has that giant claw he swings at you faster than the speed of light, plus he looks kinda creepy but at the same time he looks really cool!:B
