Gilgamesh
Height: 182 cm
Weight: 68 kg

An arrogant, selfish, and enigmatic Archer-class Servant. He appears familiar with Fuyuki City and claims to have a past relationship with Saber. Typically clad in an ornate golden armor, he possesses an immense number of Noble Phantasms, though none are representative of his true identity.

Gilgamesh was initially summoned by Tokiomi Tōsaka in the 4th Holy Grail War, who used a fossil of the first skin ever shed by a snake as a catalyst. With Tōsaka's death, Gilgamesh participated with Kirei Kotomine to obtain the Holy Grail, intending to cleanse the world of humanity, which he felt had become corrupted and vile, thus not worth of his reign. When Kiritsugu Emiya killed his Master, Gilgamesh remained in the physical world long enough to be drenched by the pollution within the tainted Holy Grail. Contact with this ichor normally corrupts a Servant's ego, but Gilgamesh resisted submission to the evil influence. However, the saturation converted his spiritual body to one of flesh and blood, and Gilgamesh also become more eccentric and excitable.

In the novels his power is described as the naturally unlimited form of human strength and likened to "adrenaline power" that can give people superhuman strength in times of emergency.
