Catakiller, Jr. is a Badnik usually found in the Angel Island Zone. Vaguely related to the Caterkiller, this blue Badnik is protected by an electrically-pulsating body, but can be destroyed with a Spin Attack to the head.
Although Catakiller, Jr. did not appear in a regular issue of Sonic the Comic, it featured in the Sonic's World section of the first Sonic the Summer Special.
