Eaco di Garuda, titled Celestial Valiance Star, stands among the three Judges of Hell in Hades’ forces. His Surplice, crafted in the image of the mythic Garuda, merges avian ferocity with humanoid form, embodying lethal speed and devastation. Tasked with guarding Antenora in the Underworld, he commands alongside Wyvern Rhadamanthys and Gryphon Minos under Hades’ dominion. A master of combat, Eaco unleashes techniques like Garuda Flap—propelling foes skyward before slamming them earthward—and Galactica Illusion, a blinding storm of energy and celestial mirages. His Galactica Death Bring strikes the nervous system, while Surendrajit immolates loyal followers to conjure fiery plumes. Renowned as the swiftest Specter, he dominates adversaries with unmatched velocity. In the Underworld siege, Eaco disrupts Gemini Kanon’s clash with Rhadamanthys, overwhelming Kanon with Galactica Illusion until Phoenix Ikki intervenes. Overconfidence leads Eaco to mock Ikki’s resilience, only for the Phoenix Saint to endure his assaults and unravel Galactica Illusion via Phoenix Genma Ken. The duel culminates in Ikki’s Hou Yoku Ten Sho, shattering Eaco’s Surplice and extinguishing his threat. The manga sequel *Next Dimension* reveals Suikyo, Eaco’s predecessor, battling in the 18th-century Holy War, weaving a cyclical legacy for Garuda’s mantle. This lineage anchors Eaco in intertwined Greek and Hindu lore. His past intertwines with the Specter Violate, whose unwavering loyalty in life and death exposes a sliver of humanity beneath his merciless facade. Strategically adept yet prideful, Eaco derides allies like Rhadamanthys for perceived frailty. His design—hair veiled beneath the Surplice’s helm—echoes his fellow Judges while marking him as the first to fall in battle. Narratively, he bridges the Bronze Saints’ ascendance and the Gold Saints’ enduring influence, underscoring the generational evolution pivotal to the *Inferno* arc.
