Archer is Gilgamesh, the King of Heroes who ruled Uruk and befriended Enkidu. During life, he had a key to the gates of his vault crafted, but he did not utilize it. The key was exceedingly ornate, and about the length and weight of a small survival knife. The jewels ornamented on the key were extremely valuable, both magically and monetarily. The key was filled with some magical energy of unknown origin. Viewing it as a trifle because there were none who would lay a hand upon his treasures, he threw it away. It eventually found its way into the hands of his summoner's ancestor, and while the key was filled with magical energy, he never found the vault. It stayed within his family until Archer's summoner used it to summon him instead of the first skin shed by a snake.
Normally, being summoned in an era where his property was sullied by the consumption society of the early 2000s, Gilgamesh would usually be in a worse mood overall. When learning that is best friend, Enkidu, was summoned did his personality become more stable.
Archer is summoned by a magus wishing to restore his family's honor, but he is killed by another magus, Tine Chelc, moments after the summoning is complete and becomes her Servant. After she introduced herself, Tine then took Archer to meet the many people who wish to serve their king. Archer declared to Tine that he was initially not interested in participating the War, and he would leisurely wait until a worthy opponent shows up, where he then took out the Potion of youth with the intentions of drinking it. However, as Archer learns that his best friend, Enkidu, was also summoned did he change his mind. After declaring to Tine that she should rejoice in how she will witness her king fight with all his might, he then gives Tine the Potion of youth where he declares he will no longer need it.
Gilgamesh has access to the Gate of Babylon and Ea. Orlando Reeve is most worried about his strength, and he plans on using his force to somehow overpower him before he can retaliate. While he is definitely the strongest Servant within the Holy Grail War, it is noted that the Player's ability to summon five Servants at once with all of his Command Spells may be too much for even the King of Heroes.
