Chaosteros

Mr. Hammond, after careful consideration, I've decided not to endorse your park.

The Chaosteros is one of the most fearsome predators on the planet LV-117. This jungle-dwelling behemoth sports clawed hands and feet, a bladed tail, a mane of spikes, and massive jaws lined with dagger-like fangs. It's not much of a picky eater, either - if it moves, it's prey, no matter how indigestible.

Fiction

2005 IDW continuity

Shortly after crashing on LV-117, Wheelie encountered a marauding Chaosteros. Proving unresponsive to the universal greeting, the creature bit Wheelie's arm off and wandered back to its lair. The limb proved unpalatable, however, and passed right through the Chaosteros' digestive system, allowing Wheelie to retrieve it from its feces later. Spotlight: Wheelie He eventually learned to tame animals using music and intended to take a Chaosteros with him on his passage off the planet. When his ship was in danger of being taken by Jhiaxus, Wheelie released it alongside an Arachnosaur to fight on his behalf, but both creatures were killed by Monstructor. Syndromica (2)

Wheelie apparently procured another Chaosteros and introduced the species to his next destination, LV-118. One of them attacked Rodimus when he tried to hide in its cave and took a chunk out of his leg using its claws, but was chased off when the experienced Wheelie showed up, playing music and shooting it in the eye with his slingshot. He later used his music to summon that same Chaosteros to keep Codder and "the Admiral" busy while he and Rodimus stole their ship. The Stars My Destination

Notes

• The Chaosteros's design appears to have been inspired by Chaos, an alien monster from the Generation 1 episode of the same name.
