Caterkiller (Sonic the Comic)

The Caterkiller is a character that appears in the Sonic the Comic series published by Fleetway Editions. It is a bat-based Badnik variant created by Dr. Ivo Robotnik. They were among the first generation of Badniks Robotnik produced and have remain active units in the doctor's army since his early days.

History
In the Caterkillers' early days, they and an army of Badniks tried to defend one of Dr. Robotnik's devices from Sonic the Hedgehog, but were easily torn apart by the hedgehog.

A Caterkiller and other Badniks later cornered Tufftee, who had gotten himself into a pit in the Marble Zone, where they threatened to kill him before deciding to turn him into a Badnik with the Portable Badnik Processor. However, the Caterkiller and the Badniks were destroyed when Sonic spun to Tufftee's rescue. Following a failed battle against Sonic, a damaged Caterkiller reported back to Robotnik, who subsequently mobilized an army of Badniks (Caterkillers includes) for invading the Hidden Zone. At the site however, an amnesiac Sonic regained his memory in time to destroy the Caterkillers and their army. More Caterkillers were over time sent out on different missions, such as aiding in the Marxio Brothers' schemes which were foiled by Knuckles and trying in vain defeat the Freedom Fighters who were bolstered by Shortfuse the Cybernik.

On the day where Robotnik's tyranny ended, hundreds of Caterkiller and other Badniks were called into stopping the rebelling Mobians until a global electromagnetic created by Super Sonic destroyed them all. Later, at an operating station on Flickies' Island, Robotnik started building improved and more dreadful-looking Caterkillers. Three of these Caterkillers were sent tunneling under the sea to attack Skegpool from below, but during the attack, Tails happened to take them all down at once. D.R.A.T. eventually acquired the plans to build their own Caterkillers without the need for organic batteries, but Sonic and Tails handled them easily after they were unleashed.

Personality
Early versions of Caterkillers were slow and stupid, but also very mean and quite dangerous in enclosed areas. As time went on, they have become more aggressive.

Powers and abilities
Despite having a strong bite, Caterkillers do not have many skills, but as time passed, later models have got faster and are now able to burrow through the ground.
