Caterkiller

The Catterkiller was a first-generation Badnik created by Dr. Eggman in the original Sonic the Hedgehog video game for the Sega Genesis and Game Gear.

Physical Appearance
The Catterkiller model is based heavily upon that of a real-life caterpillar, both in its shape and the way it moves across the ground, stretching its four segmented body parts up and down to crawl along its programmed territory. Its two antennae located at the tip of its head may help give it instructions based on the complexity of its design. An interesting feature of this Badnik is its ability to separate its four body parts if one of its 3 spiked segments are hit. As long as the head remains intact, this Badnik will continue to survive, albeit scattered throughout the area. Teeth can be seen on the front of the Caterkiller, but they have never been documented to have attacked with these. Standard colors for the Caterkiller model were a purple body shell with a gray underside, with a smattering of yellow for the antennae and spikes.

Attack Pattern
The Catterkiller's main attack pattern lies in its ability to only have one segment that can be destroyed without any injury to the attacker, making it more of a defensive Badnik than an offensive one. As stated in the Physical Appearance section above, not only will the attacker be hurt if they try to hurt the last three segments, but the segments will detach and scurry around the area, causing even more potential damage. Sonic had to be extremely careful when dispatching these enemies.

Extra Notes
-The Catterkiller is the precursor to the third-generation Catterkiller Jr.. -The Catterkiller model has been seen in many of the various early Sonic the Hedgehog comics series, notably the Archie Comics version.
