Garuda Aiacos

 Celestial Valiance Star, Garuda Aiacos (天雄星ガルーダのアイアコス, Tenyūsei Garūda no Aiakosu) is one of the prominent characters throughout the arc. Along with Wyvern Rhadamanthys and Gryphon Minos, he is part of a collective known as The 3 Judges of Hell. Aiacos' power stems from the Celestial Valiance Star (天雄星).

Special Techniques
With his role as one of the big 3 Judges of Hell, Garuda Aiacos is easily one of the mo

 re powerful spectres in the Underworld.

Aiacos has two main techniques at his disposal. The "Garuda Flap" is a two part attack: Aiacos first expels a gust of wind through his arms, sending the opponent soaring miles into the air at top speed. The spectre then crosses an "X" on the ground with his feet and begins a 3 second countdown. At the end of it, the opponent is knocked back down to the ground, usually crashing onto the "X" as marked.

"Galactica Illusion" is the Garuda's stronger technique. At its most basic, it is a more powerful version of the "Garuda Flap", minus the countdown. Grand illusions of demonic eyes are seen flashing in the background as Aiacos unleashes a high speed air current at his opponent through crossed arms.

Plot overview
Along with Gryphon Minos, Garuda Aiacos appeared on the scene during the fight between Wyvern Rhadamanthys and Gemini Kanon. It seems Rhadamanthys was having difficulty dealing with the Gemini Gold Saint, and would've tasted defeat had the two Judges not intervene. Garuda immediately took an interest in the battle and hit Kanon with the "Galactic Illusion". Kanon survived, but soon fell victim to Gryphon Minos' "Cosmic Marionettion" technique.

Bronze Saint Phoenix Ikki soon arrived to save Kanon from Minos. Aiacos, still itching for a good fight, challenged the Phoenix Saint to a match-up. Aiacos demonstrated his superior speed and agility over the saint, and caused sufficient damage with the "Garuda Flap". Ikki was hurled into the air before brutally crashing into the ground. However, the Phoenix was still intact. Amused, Aiacos gave the Phoenix a second taste of the technique. This time, Ikki did not land as expected—instead, the bronze saint countered the move and swiftly smashed Aiacos' back as he recovered. Standing triumphantly over his opponent, Ikki stated that the same technique cannot be successfully used against a saint twice.

Of course, Aiacos was not out, and offered to show Ikki a stronger move—the "Galactica Illusion". Hundreds of illus ional eyes flashed open within a cosmic storm as an air current sent Ikki flying into the air and to his apparent demise. The Garuda began to gloat that he had finally finished off the Phoenix, but soon enough, Ikki was on his feet once more. At this point, Gemini Saint Kanon warned Aiacos that every time Ikki was resurrected, he would become more powerful than before. Aiacos, refusing to believe in such nonsense, attacked the bronze saint with swift straight punches—with none connecting. Aiacos was in disbelief at Ikki's newfound speed, but before he could do anything else, the Phoenix hit him with his infamous "Phoenix Genma Ken". The spectre shrugged off the move and responded with another "Galactica Illusion" -- but to his horror, Ikki stood unharmed and reiterated his earlier statement—the same technique cannot be successfully used against a saint twice. He then reversed the attack, and Aiacos' entire body was completely hacked to pieces by his own move.

Aiacos snapped out of a trance when he realized it was an illusion—the effects of Ikki's demonic "Genma Ken". Minos and Rhadamanthys were dumbfounded as to what had happened, while Kanon stood amazed at having witnessed the "Genma Ken" again. Ikki then declared that the match was over; Aiacos was no longer a suitable opponent for him. Enraged at the idea that a Judge of Hell like himself would lose to a mere bronze saint, Aiacos charged towards Ikki with another attack. Ikki, now more concerned with the rumors of his brother having become the next avatar of Hades, decided to quickly end the fight. Using the powerful "Hou Yoku Ten Sho", the Phoenix obliterated the Garuda with a decisive end.

Surplice
Garuda is present in Hindu mythology. It has beak and wings of an eagle and the human body and considered the king of birds. It's a bird that burns like embers of fire, similar to Phoenix. He was the son of the great sage Kasyapa and enemy of Vinatea. Enemy of the snakes, healed those who were attacked by them. When Kadru kidnapped the mother of Garuda, he demanded as ransom the Water of Life. Indra was the guardian of water and Garuda had to defeat him to get it, and then deliver the water to his mother was released. Often, the Garuda is depicted carrying the god Vishnu and his wife Lakshmi.. In Tibet the Garudas are sometimes associated with the king of hell.

Lost Canvas
He was shown giving orders toBehemoth Violate, before dismembering a Skeleton soldier with an unnamed technique, with which he traced a cross in the air, generating an extreme cutting force.

He is portrayed as quite heartless, similarly to Griffon Minos, but has an even "darker" vision of the world, as he treats his subordinates as slaves both living and dead with great disdain, serving him only by the fear of his power. This vision was questioned by Sagittarius Sisypho when the two flying boats encountered each other. The Specter Violate harbored deep loyalty towards him.

He used his technique Garuda Flap (ガルーダフラップ, Garūda Furappu), from Kurumada's original manga, to send Behemoth Violate to attack the Bronze Saints who are fixing the Boat of Hope. The attack consists in throwing the enemy to the sky into a free-fall ending in a earth-shattering impact on the ground, later on, he used it against Sisyphos. Aiacos also displayed a new attack, Surendrajit (スレーンドラジト, Surēndorajito, from Hindi:सुरेन्द्र: Champion of Indra), with which he burns to death one of his loyal Skeletons, to enable him to transform their souls into a rain of flaming feathers.

He also exhibits Galactica Death Bring (ギャラクティカデスブリング, Gyarakutika Desu Buringu), a technique that relies on immobilizing and burning the opponent's central nervous system from the inside out by channeling his Cosmo intensely through the eyes of the mask headpiece of the Garuda Surplice. He performed it on Sisyphus prior to trying to inflict the killing blow with his Garuda Flap. Even though Aiacos was successful in connecting both attacks, Sisyphus was able to survive their tremendous force. Aiacos is also capable of generating a X-like shaped symbol, which explodes creating a powerful burst of energy, damaging the surrounding area and enemies within it.

Afterward, Aiacos is engaged by Sisyphos again, after awakening to the Eight Sense. Summoning all of his Cosmo, Sisyphos strikes Aiacos powerfully to the chest, shattering his Garuda Surplice and sending him flying, apparently killing him. However, it is later revealed that the Garuda Specter survived Sisyphos' assault. Hades then used Violate's body as a puppet to punish Aiacos, and he does not resist, preferring to die by her hand than die alone. However, she stops mid-blow and starts crying. He was amazed to see that even dead Violate was loyal to him. Then he admits he had profound bonds with her. He buries her body and accepts Bennu Kagaho's punishment. His Garuda Surplice is completely obliterated hence Aiacos is freed from the Masei (魔星, Demonic Stars). Kagaho states that from now on Aiacos is just a mere human, being given back his "human name", which is surprisingly revealed to be the same as Crateris Suikyō, a character also appearing in Kurumada's Saint Seiya Next Dimension, in the continuity of which, is established as the former Crateris Silver Saint and Tenma's master.
