Caterkiller (IDW)

The Caterkiller is a character that appears in the Sonic the Hedgehog comic series and its spin-offs published by IDW Publishing. It is a mass-produced model of Badniks created by Dr. Eggman.

Past
After Sonic the Hedgehog thwarted Dr. Eggman in their last encounter, the doctor disappeared while his Caterkillers and the rest of his Badnik army remained. Without a leader however, the Caterkillers were directionless and no longer a unified threat. Even so, they would still randomly attack anyone they came across (although such incidents were more accidental than aggression-based ).

Personality
Basically, the Caterkillers are mindless and silent drones programmed to follow their leader's every command. As such, when left without a leader to follow, they become directionless and only able to cause harm by accident. Under a guiding force however, they carry out their commands without question.

Allies

 * Eggman Empire
 * Badniks

Trivia

 * The Caterkillers are based on the enemy of the same name that appears in the Sonic the Hedgehog video games.
