Sneagator

Sneagator is a character from Yudetamago's manga and anime series Kinnikuman. Sneagator was another of the Devil Knights, and the teacher of the Seven Devil Chojin. He had the ability to shape-shift into any form ranging from a claw to a snake to a shoe. Generally, his form was reptilian, and wore sneakers, or had laces somewhere on it. The only exception to this was his last form, the Claw form. He faced Kinnikuman and was smashed into the mat in the end. His original form was the foot of a T-Rex. His grandson is Maxman, one of the villains in Kinnikuman Nisei. (Source: Kinnikuman Wiki)
