Assnick is unable to move his limbs enough to walk, resulting in him needing to use a special spring from his rear end to bounce around for travel most of the time. Assnick's primary ability is his ability to call out at a volume that human eardrums cannot handle without experiencing severe pain and headaches. Once he has his victim pinned to the ground, he'll proceed to use this call liberally, eventually resulting in the subject's head exploding.
