True Archer

True Archer's True Name is Alcides (アルケイデス), the human side of Heracles whose divinity and immortality has been lost through interference from his Master's Command Spells awakening past memories from his life and mud from the Fuyuki Grail. In a way, he could be called Heracles Alter, although he refuses to be called as such.
