Unlike the other Nocturnals, Firelion prefers to use katana and wakizashi swords instead of firearms. When enraged, he becomes a fiery hellstorm of flames and blades. In his first appearance in the Black Planet miniseries, he lays waste to an entire building full of synthetic mob hitmen assigned to guard a captured Doc Horror. His reputation is such that even synthetics with no free will of their own show fear when they realize who he is.
