Chomps, Knuckles the Echinda's pet, is a carnivorous dinosaur with a teal underside and the top of his body being magenta.
Chomps is the only other known inhabitant of Floating Island in Sonic Underground, and served Knuckles by devouring intruders who came onto the island. He wanted to eat Sleet and Dingo, but after Knuckles released them they ran away, leaving behind a holo-projector with falsified images of Sonic, Sonia, and Manic the Hedgehog, planning to steal the Chaos Emerald. Chomps ate the projector, causing the images to appear out of his mouth and nostrils. Thanks to this, the Hedgehogs were able to determine why Knuckles was attacking them. Chomps only appeared in the episode "Friend or Foe".
- Chomps is voiced by Dee Bradley Baker.
