MAXman

The grandson of Sneagator, who was an older-generation of Devil Chojin that was defeated by Kinnikuman. He can transform into a sneaker at will. Kinniku Mantaro fights him after he beats up Seiuchin, which happens after Mantaro's match against Tel-Tel Boy at the Nippon Budokan. During the fight, Mantaro figures out that a shoe's worst enemy is faeces; this used to defeat MAXman.
