Retro

Retro, also known as Experiment 210, is an illegal genetic experiment created by Jumba Jookiba and a character in the Lilo & Stitch franchise. He is designed to reduce individuals, animals, enemy weapons, and technology to their primitive or prehistoric state; wrapping his tongue around the de-evolved object or victim and spanking his bottom three times will reverse the transformation. His one true place is at a wildlife park, resurrecting extinct animals for a Mesozoic zoo.

Background
Physical appearance
Retro is an orange, mammalian/reptilian dinosaur-like experiment with black eyes, a purple nose, tiny gold-tipped ears, gold markings on his back and gold spots around his eyes, and a dense, short tail and thick legs. His tongue is notably extendable.
Powers and abilities
Retro can wrap his extendable tongue around an individual or object, and as he lets go, the individual or object de-evolves into its primitive/prehistoric state. He can also "de-evolve" something that is already deceased as long as its remains are still intact, as he was able to bring a Tyrannosaurus rex back to life.

Retro can de-evolve multiple individuals/objects at once when he wraps his tongue around them altogether, and the same applies to reversing the de-evolving effects.

Weaknesses
Retro's effects can be undone by wrapping his tongue around the de-evolved individual or object and spanking his bottom three times.
