Crimson

Crimson is a large muscular man, wearing one shoulder blade and a head band. What makes him unique is that he has a third eye on his forehead. Crimson is a member of the Reverse Maruhage Empire's Four Heavenly Kings. He is also the first opponent faced by the allies of Bo-bobo heading up through Hydrate's floating fortress. Crimson seems to enjoy showing off his strength, and is completely loyal to Hydrate. (source: Bobobo Wiki)
