Femto

He is the demonic form of Griffith, a central figure in the story. After sacrificing his comrades in the Band of the Hawk during the Eclipse event, he is reborn as Femto, one of the God Hand, a group of immensely powerful demonic beings. He gains near-godlike powers, but the transformation comes at the cost of his humanity. His actions and transformation mark a significant turning point in the dark and violent narrative of Berserk, shaping much of the series' ongoing conflict.
