, Catakiller, Jr.s appear only at Sonic the Hedgehog 3 Angel Island Zone where they hover back and forth at medium speed in midair. When the playable characters get close to them, they will release what appears to be electrical waves from the generator rings on their body segments which can damage the player even if they possess a Thunder Shield.
These Badniks can only be defeated by attacking their head. Touching any other part of their body, even if they are not releasing their electric attack, will damage the player.
, and its expansion Sonic Mania , the Catakiller, Jr.s appear as enemies. In terms of design, they look exactly like they did in their debut game.
