Gilgamesh (Fate)

Gilgamesh, also known as Archer, is a villain from the Fate series. He is the Archer-class servant of Tokiomi Tohsaka in Fate/Zero, and later forms a contract with Kirei Kotomine that lasts ten years later into Fate/stay night. He has a fascination with Saber during both stories.

Identity
Gilgamesh is the great half-god, half-human king who, during the years before Jesus Christ was born, ruled over the Sumerian city-state of Uruk, the capital of ancient Mesopotamia. He was an ultimately transcendent being so divine as to be two thirds god and one third human that no other person in the world could match him. He was a despot with high divinity who thought he was invincible. While not really a legend, he is said to have actually existed during the Sumer Dynasty five thousand years ago. He was the King of Heroes who possessed all things in the world, whose tale is recorded in mankind's oldest epic poem, "The Epic of Gilgamesh" which portrays him as a hero, destined to be king and achieve great challenges, who is driven to fulfill his destiny, facing these challenges themselves together with his best friend Enkidu.
