The Catakiller, Jr.[1] (メラモーラ[2] Meramōra?), also known spelled as Caterkiller Jr.,[3] is an enemy that appears in the Sonic the Hedgehog series. It is a mass-produced, caterpillar-based Badnik model created by Dr. Robotnik.


Much like the Caterkillers, Catakiller, Jrs. are based on caterpillars. These Badniks' bodies are composed of seven blue and spherical segments. The first of these segments serves as the head which has small black eyes. Their next three body segments after the head have electricity generator rings around them.



In Sonic the Hedgehog 3 and the lock-on game Sonic the Hedgehog 3 & Knuckles, Catakiller, Jrs. appear only at 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.

Powers and abilities

Caterkiller, Jrs. are capable of flight. Their body segments can also release electrical waves which can be lethal for anyone who touches them.
