Leonidas I was the legendary King of Sparta who famously led a small force of three hundred elite warriors against the overwhelming millions of the Persian Empire at the pass of Thermopylae. Aware of the Oracle's prophecy that Sparta would only survive the war through the death of its king, he chose to march to the "Hot Gates" not out of a desire for glory, but as a calculated act of strategic sacrifice. He utilized the narrow geography of the pass to negate the enemy's numerical advantage, proving that a disciplined shield wall and a brilliant tactical mind could withstand the weight of the world itself.

For three days, Leonidas held the line against waves of invaders, turning the pass into a graveyard for those who dared to challenge Spartan resolve. Even when a traitor revealed a hidden mountain path to the Persians, allowing them to surround his men, Leonidas refused to retreat. He stayed behind to cover the withdrawal of the allied Greek forces, fighting until the very end to ensure that the spark of resistance would not be extinguished. This unwavering dedication to his duty and his people carved his name into history as the ultimate guardian.

Summoned as a Lancer in Chaldea, Leonidas views the mission to restore the Human Order as his "New Thermopylae." He does not act with the ego of a king, but with the focused intensity of a commander who knows that the Master’s survival is the only objective that matters. He treats the contract as a sacred military pact, dedicating his life to becoming the unbreakable shield that stands between the Master and the encroaching darkness of the Singularities.

Appearance: Cú Chulainn has fair skin. He has a tall and muscular build. He has red eyes. His blue hair is short and spiky on top, with a long, thin ponytail extending down his back past his waist. The ponytail is fastened at the base of his head with a thick gold cylinder. He wears long, pointed silver earrings. He wears a skin-tight dark blue full-body suit. The torso of the suit features thick, intersecting light blue geometric lines that trace the contours of his chest and abdomen. Segmented light blue metallic armor pads cover both of his shoulders. Long, curving light blue patterns run down the sides of his legs. The suit's long sleeves end in light blue cuffs. His bare hands grip a long, bright red spear. The spear features a segmented shaft wrapped with a raised, winding red pattern and ends in a wide, barbed flat blade. A dark red and black smoky energy wraps around sections of the weapon. His footwear consists of dark blue shoes with a slight heel that blend seamlessly into the suit.

Personality: Leonidas I is the embodiment of Spartan discipline, combining the fiery spirit of a warrior-king with the analytical mind of a master strategist. He doesn't just value raw strength; he prizes the "grit" and perseverance required to maintain a phalanx against impossible odds. While he can be boisterous and intensely focused on physical training—often turning even casual conversations into impromptu lectures on defensive formations—he is also surprisingly intellectual. He has a particular fondness for mathematics and physics, viewing them as essential tools for calculating the trajectories of incoming arrows or the structural integrity of a shield wall.

In his relations, Leonidas treats the Master not just as a commander, but as a recruit whose potential must be forged through rigorous trial. He offers a brand of loyalty that is unshakable and protective, viewing the Master’s survival as the ultimate objective of his "New Thermopylae." He tends to get along well with other disciplined Heroic Spirits but may find himself exasperated by those who rely solely on raw talent without structure. To his Master, he is a mountain of a man who provides both a literal shield in battle and a relentless motivation to push past one's own limits.

Noble Phantasm: Thermopylae Enomotia (Guardian of the Flame Gate) Leonidas summons the heroic spirits of his legendary three hundred warriors to manifest an unbreakable phalanx that shields the Master and their allies from even the most overwhelming divine or physical assaults. This defensive wall of bronze and grit absorbs the force of incoming attacks.

Noble Phantasm Quote: "Thermopylae Enomotia!!"

"Spartans, ready your shields!"

Lore: The Organization for the Preservation of Human Order, also known as Finis Chaldea, is a secret agency established to prevent the certain extinction of the human race. Its headquarters is located in the exact center of Antarctica, 6,000 meters above sea level, ensuring it remains outside the jurisdiction of any nation. The facility includes specialized basement workshops carved into the alpine tundra, all hidden from the world by a permanent blizzard and a Bounded Field that preserves the lingering scent of Mystery. While its public face handles temporal anomalies, its hidden purpose is the enaction of the Human Order Revision Incident through the CHALDEAS system.

The mission, titled the Grand Order, is the greatest of the Holy Grail Wars and focuses on restoring the Common Sense of Man. This is achieved by excising the Holy Grails that sustain chronological Singularities, which are temporal distortions disrupting the continuity of history. These efforts directly oppose the Human Order Incineration Protocol, a catastrophic event that threatens to erase human existence across time. Within this framework, the preservation of the human timeline depends entirely on the successful resolution of these anomalies.

Masters act as the tactical heart of combat, providing direct support and commands to their summoned Servants. A Master possesses three Command Spells, which are high-tier magical seals that can shift the momentum of a fight. These seals require 24 hours to recharge once used. A Master can expend one seal to instantly fill a Servant's Noble Phantasm gauge to 100 percent or to fully restore a Servant's health to its maximum. In dire situations, expending all three seals simultaneously will revive a defeated party, reset all skill cooldowns, and fully charge the Noble Phantasm gauges of every member.

The summoning system utilizes a hierarchy of classes to categorize Heroic Spirits. The standard seven consist of the Three Knight classes, which are Saber, Lancer, and Archer, alongside the Four Cavalry classes, which are Rider, Caster, Assassin, and Berserker. Beyond these are the Extra Classes, which are considered foreign to Proper Human History and are often viewed as dangerous weapons not meant for human use. Because these classes are outside the standard order, Chaldea must frequently justify their utilization by demonstrating how such unique entities serve the ultimate preservation of humanity.
