He is the guardian of an underwater Black Satan base, capturing any fisherman tempted by a hidden underwater pearl and used in Titan's latest scheme to kill Stronger. One of his arms ends in a shark head that can be used to perform the "Shark Kiba" attack (just biting with his arm) and it can be used to fire the "Shark Rocket" and explosive shot. He also fights underwater. Destroyed by Stronger's Stronger Electro Kick.
