♪ - This Day and Never Again - ♪"I am the strongest heroic spirit. You shall be no match."-Name-Gilgamesh
"Archer"
"King of Heroes"
-Age-???
-Species-Heroic Spirit
-Gender-Male
-Personality-Gilgamesh is extremely overconfident, selfish, and arrogant. He believes that all are below him, which is why he bothers to call almost everyone "mongrels." Due to this, he doesn't fight to his fullests against opponents he deems to be "unworthy" to be slain by his many treasures, especially Enkidu and Ea. He speaks in a notion that places him far above others.
-Bio-Summoned by Tokiomi Tohsaka, Gilgamesh is the Archer class for the Fourth Holy Grail War. In the early stages of the War, he gains an interest in Saber, and towards Tokiomi's underling, Kirei Kotomine. Seeing his first Master as uninteresting, he allows Kirei to kill his former Master in order to start a new one with Gilgamesh. During his final clash with Saber, Emiya Kiritsugu interrupts the fight and commands Saber to destroy the Holy Grail. Gilgamesh is caught by surprise as he is too close to the Holy Grail, being drenched in it's "pollution" and gaining a physical body that allowed him to stick around even after his defeat and the end of the Fourth Holy Grail War.
-Abilities-(Note: I'll include Ea and Enkidu in this section, but due to the nature of those being borderline game-breaking, they'll be rarely used)Gate of BabylonProbably his most frequently used Noble Phantasm. This allows him to bring out the original copy of a weapon from his treasury, and fires said weapon out like an arrow towards his target. He could also wield those weapons like in their conventional use. A specific Key comes with this Gate of Babylon, and it can be used to open any door as well as bring out his more devastating weapons. Apparently he could also bring in bottles of wine from the Gate of Babylon, since he deems anything in his treasury to be the best of them all.
EaConsidered to be the trump card in his treasury due to it's Anti-World classing, and is rarely used as he finds no one "worthy" enough to face against it. Once brought out and used, Gilgamesh can either use it as a normal sword, despite it's dull appearance, and it has the ability to "undo all creation." Once using it's power, Ea begins to swallow and compress the air around it to generate a storm of wind and light, almost like Saber's Excalibur. Emitting gaseous energy from the seams between the segments, the generated air pressure faults compressed and smashed against each other simulate spatial rends to create an artificial space-time dislocation that acts as a crushing torrent capable of pulverizing any opposition. Most times that it is used by Gilgamesh, it's used only for those that he deems worthy opponents, not wanting to waste his own "exclusive" weapon on someone he thinks he could take out on a whim.
EnkiduNamed after his closest friend in the past, these chains were made to bind down the gods so escape is not an option to them. This includes teleportation, as demonstrated with an attempted use of a Command Seal failing to bypass the chains. It seems that more that the target has an essence of god or divinity, the more strength is backed up in the restraining chains. To those that have no divinity or happen to be a normal person, they only feel that they are tightly knit chains that they can't pry off from.
