"Griffith, later known as Femto, is the main antagonist of the Berserk franchise.
He is the founder and leader of the mercenary band known as the Band of the Hawk. As a mercenary, Griffith fought in the Hundred Year War, restored peace to the war-torn kingdom of Midland, and was once a close friend and ally of Guts. After being tortured, however, he used the Eclipse to sacrifice his entire band and was later reborn as Femto, the fifth and final member of the God Hand. He is the arch-nemesis of Guts and Casca."
