 Zebra is usually a clean fighter (White Form), but when he steps into Parthenon's shadow his stripes cover most of his body and his brutal side emerges (Black Form).He is also able to do the Muscle Inferno, one of the sacred techniques of the Kinniku clan, but it was revealed that it is an incomplete version, allowing Kinnikuman to escape the move and defeat Zebra.He returns in the True Devil Choujin arc, fighting Mariquitaman at Castel del Monte, and despite reconciling his two forms and perfecting the Muscle Inferno, he is defeated nonetheless.
