Biography
Gray the Ninelives is a very large man known for being indestructible. The manga version shows that he is actually formed from nine dwarfs controlling a mechanical suit from the inside, allowing them to keep fighting until all nine are dead. The suit is destroyed and only two survive. They are captured and turn over their coin, and later escape. The anime version is a cyborg whose only remaining human part is his brain, which is deeply encased in armor. Nicholas D. Wolfwood kills him after the armor is melted off enough to see the brain.
