Berserker

He is a colossal, statue-like giant with dark, stony skin and an immense muscular physique that radiates overwhelming power. His face is framed by long, unruly black hair, and his eyes burn with a fierce, supernatural red glow. He wears minimal tattered clothing including a dark loincloth with gold trim and wields a massive, crudely shaped stone axe-sword.

Ferocious, loyal, protective, instinctual, stoic, and indomitable.

Berserker-class Servant

Heracles is the legendary demigod son of Zeus, famous for his superhuman strength and the completion of the arduous Twelve Labors. He was summoned as a Berserker for the Fifth Holy Grail War by the Einzbern family, a ritual that stripped him of his reason in exchange for raw combat power. Despite his madness, he retains a deep, instinctual bond with his Master, Illyasviel von Einzbern, serving as her ultimate shield and most terrifying weapon.
