Caterpixel

The Caterpixel is a character that appears in the Sonic Boom television series. It is a mass-produced, caterpillar-based digital robot created by Nominatus. They serve as Nominatus' personal brand of Badniks and make up the majority of his army.

Appearance
The Caterpixels are based on real-life caterpillars, both in shape and in the way they move across the ground, stretching their segmented body parts up and down to crawl. Their bodies each consist of four spherical segments with a head on the front. They possess grey-white underbellies, disk-shaped recesses on each side of their body segments, and sharp plating down their backs. Their head segments meanwhile, have plating up front with flat fins on the sides and top. They also have a large white-grey jaw with fangs, antennas protruding from their nose areas, sharp ear-like horns, and menacing yellow eyes with orange sclera, eyebrows and dark bags.

The Caterpixels come in two color variants: red-violet and lavender with pale yellow antennas, and mint and green-yellow with purple antennas.

Season two
Created by Nominatus, the Caterpixels were brought into the real world by Nominatus with the Built-it Box to battle Sonic and his allies when the heroes stood in the way of Nominatus' plans to conquer the world. The Caterpixels and their allies had the upper hand at first, but got pushed back when Dr. Eggman and his Badniks came to Team Sonic's aid. The Caterpixels were then sent back to cyberspace by Tails with the Built-it Box.

Personality
Like Dr. Eggman's Badniks, the Caterpixels are silent, single-minded, ruthless in battle, without personalities, and unquestioningly dedicated to their leader's orders.

Powers and abilities
The Caterpixels are noted to be tougher to defeat than Dr. Eggman's Badniks. When curling up, they can protrude sharp spikes from under their armor to injure opponents attacking them directly. Their physique also allows them to slither around attacks, making them hard to hit.

Trivia

 * The Caterpixels' name ins a portmanteau of "Caterpillar" and "Pixel".
 * The Caterpixel is very similar to the Caterkiller, an enemy that debuted in the original Sonic the Hedgehog video game for the Sega Mega Drive. Like the Caterkillers, they can even injure their opponents via spikes.
