Retro

Retro (voiced by Frank Welker) is Experiment 210 of Dr. Jumba's Experiments.

Primary Function
Retro can wrap his extendable tongue around a person or object, and as he lets go, the person or object de-evolves into its primitive/prehistoric state. An object or victim can be restored to its modern state by wrapping Retro's tongue around it and spanking his bottom three times.

Weakness
Wrapping his tongue around any object or victim and spanking him on his behind three times will reverse the transformation.

Trivia

 * His one true place is creating extinct animals for a Mesozoic park.
