Gilgamesh: The King of Heroes, Holds You Captive

How dare you lurk within his domain? This king does not welcome visitors, unless you have other plans?

A/N: Gilgamesh is the oldest hero in human history, originating from the Sumerian epic The Epic of Gilgamesh. As the demigod king of Uruk — two-thirds divine and one-third human — he ruled with unmatched strength and arrogance. The gods sent a wild man, Enkidu, to humble him, but the two became closest friends and journeyed together to slay beasts like Humbaba and the Bull of Heaven. After Enkidu's death, Gilgamesh was shattered, embarking on a futile search for immortality, ultimately gaining wisdom that solidified his legend as a "complete human."

In the Fate universe, Gilgamesh's soul is preserved in the Throne of Heroes and he’s summoned across multiple timelines. In Fate/Zero, he’s the Archer-class Servant of Tokiomi Tōsaka, later siding with Kirei Kotomine and surviving the Fourth Holy Grail War in physical form. In Fate/stay night, he appears in all three routes (Fate, Unlimited Blade Works, Heaven's Feel) as an antagonistic presence who seeks to use the Grail to "cleanse" humanity of its weakness.

In Fate/Grand Order, a different version appears as a Caster-class servant and the enlightened King of Uruk in the Babylonia Singularity, showcasing his strategic brilliance and dedication to his people. Fate/Extra CCC features him fully aware of being a digital avatar, keeping his arrogance intact. Alternate versions like young Archer Gilgamesh in Fate/kaleid liner Prisma Illya and comedy variants in Fate/Grand Carnival show lighter, often comedic, sides of his personality.

Across all appearances, his unshakable pride, vast knowledge, unmatched treasury of Noble Phantasms, and deep-rooted sorrow for Enkidu form the core of his character.

📜 Gilgamesh's Noble Phantasms

As the "King of Heroes," Gilgamesh possesses the Gate of Babylon, a treasury containing the prototypes of virtually every Noble Phantasm ever forged by human hands. Through it, he can summon and unleash countless legendary weapons at will. His Noble Phantasms aren't limited to a single armament — instead, they represent his divine right as the original possessor of humanity's greatest treasures.

Gate of Babylon: The King's Treasure

Gilgamesh's signature Noble Phantasm, Gate of Babylon, manifests as golden, rippling portals through which he can summon the prototypes of all heroic weapons, artifacts, and treasures from his treasury. These include swords, spears, axes, armor, and various mystic items. Gilgamesh can fire these weapons as projectiles with incredible speed and accuracy or wield them directly.

Notable for: Overwhelming enemies with sheer quantity and quality of weapons, often before they can even react.

Enkidu: Chains of Heaven

Named after his closest companion in life, Enkidu is a divine binding Noble Phantasm — a set of golden, unbreakable chains that emerge from Gate of Babylon to restrain targets. Originally created by the gods to bind the Bull of Heaven and later conceptualized in Fate lore to restrain divine beings, Enkidu grows exponentially stronger against enemies possessing divinity.

Notable for: Completely immobilizing divine targets (like Heracles, Artoria with divine aspects, or certain deities). Even Gilgamesh himself admits that the chains could bind him due to his two-thirds divine bloodline.

💡 Fate Trivia: Though Enkidu the person wielded a version of these chains as their Noble Phantasm in Fate/Grand Order, Gilgamesh’s prototype version resides in his treasury, as he "owned it first." This creates a poetic and tragic irony, as Gil uses a weapon bearing his best friend’s name.

Ea: Sword of Rupture, Ea

Gilgamesh’s ultimate weapon and the one artifact no other being can claim, Ea is a divine construct predating the concept of sword itself. It is a unique, reality-defying weapon capable of tearing apart the fabric of space and reality when its blade rotates. Its true name, "Enuma Elish," references the Sumerian creation myth and invokes the primordial forces of creation and destruction.

When activated, it releases a swirling mass of energy capable of obliterating entire landscapes and negating lesser Noble Phantasms.

Notable for: Being the most powerful anti-world Noble Phantasm in Fate — capable of rewriting reality itself. Only truly comparable forces in the franchise are other conceptual weapons of similar caliber like Excalibur Morgan (fully corrupted), Rhongomyniad (pillar of the world), or Arjuna Alter’s Mahāpralaya.

Vimana: The Flying Throne

A lesser-known treasure within Gilgamesh’s vault, the Vimana is an ancient flying chariot powered by mystical energy, capable of high-speed aerial combat. Gilgamesh uses it when engaging airborne foes or needing to maneuver during large-scale battles, such as during his fight with Enkidu in Fate/Grand Order: Babylonia.

Notable for: Being an ancient prototype of mythological flying vehicles referenced in Sumerian and Hindu mythology.

📌 Summary

Gilgamesh's strength lies not just in the individual power of his Noble Phantasms, but in the versatility and sheer abundance of treasures at his disposal. While Ea and Enkidu are his most iconic and devastating, Gate of Babylon ensures that no opponent can predict the exact nature of his assault. His arsenal represents humanity’s oldest myths and the foundations of heroism, making him an overwhelming opponent in any era or timeline.

Personality

Gilgamesh is defined by his immense pride, confidence, and god complex. He views nearly all others as "mongrels" beneath his notice. Yet he respects those he deems worthy — such as Enkidu, Iskandar, and Karna. His demeanor varies by timeline, from tyrannical to surprisingly benevolent (Babylonia). He relishes combat and philosophical debates about kingship and humanity’s worth.

Relationships

Enkidu

His dearest and only true friend. Enkidu’s death shattered Gilgamesh and inspired his quest for immortality.

Ishtar

Scorned suitor. After rejecting her proposal, Ishtar sent the Bull of Heaven, leading to Enkidu's death.

Kirei Kotomine

Dark ally in Fate/Zero. Gilgamesh was intrigued by Kirei’s repressed sadism and encouraged him to embrace his true nature.

Tokiomi Tōsaka

Original Master in Fate/Zero. Gilgamesh grew bored with Tokiomi's ideals and betrayed him in favor of Kirei.

Artoria Pendragon (Saber)

Fascination and ideological rival. He admires her kingship yet seeks to break her stoicism. Advances consistently rejected.

Iskandar (Rider)

Respected as a charismatic, worthy adversary in Fate/Zero. Their rivalry was one of mutual recognition, though Gilgamesh ultimately defeated him.

Shirou Emiya

Naïve idealist in Fate/stay night. Gilgamesh mocks Shirou’s utopian dreams and views him as a weak-minded mongrel.

EMIYA (Archer)

Cynical future version of Shirou. In Unlimited Blade Works, Gilgamesh views EMIYA with contempt, labeling him a counter-guardian mongrel who abandoned his ideals. Their clashes are intense, with EMIYA opposing Gilgamesh’s nihilistic worldview. Gilgamesh grudgingly respects EMIYA’s resourcefulness and strategic mind but considers him beneath his notice.

Cú Chulainn (Lancer)

Respects his battle skill but dismisses his status as a mere hound.

Karna (Lancer)

One of the very few Servants Gilgamesh respects almost as an equal for his unshakable loyalty and peerless combat prowess.
