Archer

Archer is the Servant of Rin Tōsaka. Archer is actually Shirō Emiya from one of the possible future worlds. He is ultimately the winner of the fifth Holy Grail War in his world, and is a living incarnation of the "Hero of Justice". The Throne of Heroes, which preserves the souls of all Epic Spirits, exists outside of any conventional timeline, so Archer can be called from any point in history. He is linked to the jewel used to save Shirō's life, which allows him to be summoned.

Personality
He is sarcastic and cynical, considering Shirō's mentality of "wanting to save everyone" as naïve and impossible.

Magical Skills
Archer is a Faker, an individual skilled at creating imitations of objects through the use of tracing and projection of mental images to form tangible objects. Though Projection is normally ineffective at creating durable or powerful artifacts, Archer’s unique approach to this craft enables him to materialize enormously powerful and accurate copies of the images recorded in his mind. He is capable of instantly recording all information and properties of weapon, and he can read into the history of the weapon to use any skills associated with it, though the rank of the weapon is lowered by one.

He is also skilled in the basis of both Alteration and Tracing: Reinforcement; the art of temporarily strengthening the construction of objects through the understanding of their nature and perfection of defects in their structure. This is done through enhancing the fundamental proprieties of the target, such as an armor’s resistance or the sharpness of a blade. Archer employs this method on himself to enhance his physical performance, particularly in his eyesight, granting him such precise vision that it approaches a limited form of clairvoyance.

Weaponry
In addition, through the use of Alteration, he can modify a weapon to give it special properties, such as crafting Broken Phantasms, Noble Phantasms overloaded with magical energy that exponentially increases its attack power at the cost of destruction after use. All of his Projection abilities come from his Reality Marble, Unlimited Blade Works: Infinite Creation of Swords, which works similarly to Shirō's, but manifests itself instead as a desert littered with swords with monolithic black gears rotating in the sky above.

Archer is also in possession of a sleek black longbow, which is constructed from a synthetic compound that does not exist in the modern time period. It allows him to propel any weapon as an arrow, which would normally strain a weaker bow. Similarly, Archer's breastplate and boots are crafted from the same material, while the red cloak he wears is a holy burial cloth that shields Archer from spiritual interference in his surroundings.
