A space assassin of unknown origin. He has a good reputation in the underworld because he always takes down the prey he targets. Its true purpose was to become even stronger by absorbing the bodies of those it killed, so it competed in the Great Pankration in search of strong prey.

He has Zackal Gun, a gel-like semi-liquid bullet that erodes the body, Zackal Blade, a great sword that generates a phantom sword, and his deadly weapon, Zackal Chakram, a giant yo-yo made of steel.
