Rockefell

Rockefell is the captain of the Sawtooth pirates, and the rival and ex-lover of pirate captain Artemis. He has the mach ability to shapeshift into a Core Hound, but his extensive drug use means his style of fighting is erratic and berserk.

Rockefell was defeated in a confrontation with Vinsi, Elliot, Alto, and Giger. When Alto used his mach to overload Rockefell's heart, he briefly died but was unknowingly revived when Elliot shocked him as he was left on the beach. He was then approached by Sha'kala and rescued.
