Exploder

are the suicide bombers of the Necromorph. With their legs fused together in a fleshy mass, and their bodies radically twisted and emaciated (not to mention their vertically split faces). Exploders appear extremely slow, but will charge at a surprising speed, so as to force you into close combat. They then attempt to clobber Isaac with the massive pustule on the end of their left arm, which is filled with some kind of ooze. If they succeed, then the pustule will explode, killing it and causing major injuries to anything in the blast radius. Due to their "one use" nature and fairly slow movement, they most often attack in large groups, which then attempt to overwhelm the enemy. However, this group-swarm tactic also makes them dangerous to any Necromorphs nearby, including other Exploders.
