He earned his Cloth in the frozen lands of Siberia, even though earning the Cloth was not what he really trained for.
When he was a little boy, a ship he and his mother Narissa was onboard sank in the ocean. While most of the crew managed to escape along with Hyoga, his mother stayed on the ship and drowned.
After 7 years of training, he finally had the strength required in order to dive down to her and see her again.
Hyoga has blonde hair and blue eyes.
When he does not wear his Cloth, Hyoga wears black pants, a blue t-shirt, orange fur covers at his feet and small, blue sweatbands on his arms.
During the battle against Hades, blue sweatbands are added to his upper arms as well while not wearing his Cloth.
After the battle against Poseidon, Hyoga is wearing bandages over his left eye, due to an injury inflicted by Isaac.
While wearing his Cloth, Hyoga's attire is replaced by a blue garb, although this changes into a white garb from his V2 Cloth and so on.
Hyoga is a calm person, trying to stay cool and calm in battle, unlike Seiya, Shiryu and Shun. However, he is also very caring for his friends, and is shown to have feelings. Behind that cool presence is a gentle soul after all, which is later revealed during his travels with his close friends.
After he heard of Seiya's victory against Geki, he received the Cygnus Bronze Cloth and swore that he would be the one to defeat Seiya and earn the Gold Cloth.
Cygnus vs. Hydra
When he arrived at the Galaxian Wars, his opponent was Ichi. Pretending to have Ichi think he's having the upper hand, Hyoga allows the Bronze Saint to lash out with everything he has, not retaliating at all. However, Ichi suddenly reveals his Cloth's ability to grow fangs which penetrate Hyoga's Cloth.
Simply laughing off the matter, Ichi lands several more punches against the Cygnus, refusing to be made fun of. Hyoga respond to Ichi that his attacks are so weak, he can't feel anything. However, Ichi regrows the fangs on his Cloth, and once more penetrates Hyoga's Cloth. Retaliating, Hyoga grabs Ichi's arm and freeze it completely, in order to prevent him from growing fangs from that arm again.
Attacking from the above with a kick, Ichi surprises Hyoga with fangs growing from his knees as well, penetrating Hyoga's tiara. Simply laughing off the matter to Ichi's frustration, Hyoga informs the Hydra that the fangs never penetrated his Cloth, thus never poisoning him as they were meant to. Finally fighting back with his own Cosmo, Hyoga easily shatters Ichi's Cloth with his "Diamond Dust".
As Shun and Jabu's fight ended, they noticed something strange going on at the place where the Gold Cloth was. Out from the shadows, Ikki appears and attacks Shun before stealing the Gold Cloth.
Arriving in the nick of time in the forest to save Shun, Hyoga encounters his evil counterpart Black Cygnus and easily survives the "Black Blizzard" technique, before retaliating with his "Diamond Dust". However, before he could finish off his opponent, black chains appeared out of nowhere, and the three remaining Black Saint Kings introduced themselves before leaving.
Black Cygnus rematch and the Phoenix
Arriving at the Death Valley in order to battle Ikki and retrieve the Gold Cloth parts he has, Hyoga encounters Black Cygnus once again. Taking the "Black Blizzard" once more, this time without effect, Hyoga retaliates with his "Aurora Thunder Attack" which grievously wounds Black Cygnus, who kills himself while sending his remaining Cosmo to Ikki in order to inform him of Hyoga's powers.
Finding Ikki, the two Bronze Saints clash, with Hyoga's efforts proving useless against the Phoenix who easily reflects the "Diamond Dust", before retaliating with his "Gen Ma Ken", which twists Hyoga's memories of his mother. Striking back in anger with his "Aurora Thunder Attack", the Cygnus is shocked to see Ikki's Cloth lying on the ground but Ikki missing. As the Bronze Saint appears behind him, Hyoga is unable to react in time as Ikki punches straight through his Cloth and into his heart.
However, Hyoga manages to freeze Ikki's hand before collapsing to his injuries, seemingly dead.
Final flight of the Phoenix
As Shiryu, Shun and Seiya arrived, the four Bronze Saints thought they had the advantage against Ikki who was now alone and facing four Saints of the same rank. However, the Phoenix simply unleashed his "Ho Yoku Tensho" which blasted all four Saints and knocked them unconcsious. As Seiya faced Ikki once more, Hyoga gave Seiya his Cosmo, combining the "Diamond Dust" with the "Ryu Sei Ken", which finally granted Seiya victory.
After a long battle, the Bronze Saints got the Gold Cloth parts back from Ikki, but before they could get it, a new Saint that had been sent from Sanctuary, Docrates, stole all the parts, giving the Bronze Saints a new battle. When he attacked the mansion, Hyoga, Shun and Shiryu did their best, but they were no match for his "Herakles Mou Shou Ken".
Later, at the Galaxian Wars arena, Hyoga arrived when Seiya and Shun had started the fight against Docrates. Hyoga told them about a freezing technique he learned from his master and froze Docrates' feet, before lifting the giant, finally giving Seiya and Shun a chance to fatally wound Docrates and kill him with a combined "Ryu Sei Ken" from Seiya and "Nebula Chain" from Shun.
After several failed attempts to get the Gold Cloth, Pope Arles sent Silver Saints to retrieve it and kill Seiya and his friends. Hyoga would face Centaurus Babel right after hearing that Saori was Athena. After a long battle, he defeated the Silver Saint after the intervention of the Steel Saints who gave the Cygnus an opening after reflecting Babel's attack.
Later, when after Seiya broke his arm and exhausted himself, he and Saori was attacked by Jamian and Shaina. Shun took care of Jamian in one hit, due to him being confused by the Cosmo of Athena, and Shaina charged them both. After a terrible battle, they defeated her as well.
But as soon as they were about to leave, Capella and Dante appeared, who defeated both Shun and Hyoga with little effort. When they got back up, Ikki had defeated Capella and Shun took care of Dante.
The battle of the 12 Houses
As Seiya fought Aioria in the forest, Hyoga and Shun arrived at the scene, witnessing Seiya wearing the Gold Cloth and also learning that there was more than one Gold Cloth. Charging at the Gold Saint, they are easily defeated.
After Aioria leaves, the Bronze Saints discuss the power of the Gold Saints, stating that they will be ready to give anything in order to achieve victory against the seemingly invincible Gold Saints.
House of Aries
Hyoga joined the Bronze Saints to fight against Arles and his 12 Gold Saints. When they got there, Ptolemy shot Athena and they had 12 hours to save her. At the House of Aries, the Bronze Saints met up with Mu who fixed their Cloths after a short misunderstanding.
House of Taurus
At the House of Taurus, the Bronze Saints tried to rush through, but they were stopped by Aldebaran, the Gold Saint guarding the House. Trying to move forward as Seiya tried to distract the Gold Saint, the Bronze Saints are instead knocked out seconds later, leaving Seiya to fight the golden bull himself.
As they recover, they feel Seiya's Cosmo and rendezvous with him seconds after he broke one of Aldebaran's golden horns and was granted victory.
As they try to leave with Seiya, Aldebaran states that only Seiya defeated him and will be allowed to pass. Having no time to waste, the three Bronze Saints gather their Cosmo in order to freeze Aldebaran's movements, achieving victory as Aldebaran allows them passage as well.
At the House of Gemini, the Bronze Saints met up with Seiya who came out the entrance. Confused at why he's at the entrance, Seiya informs the others that he did run through and felt that he saw the exit. As they all try together, they arrive once more at the entrance, this time seeing two entrances to the House.
Splitting up, Seiya and Shiryu take one path while Hyoga and Shun take the other path.
As they run, they feel a massive Cosmo, before they finally meet the Gemini Gold Saint who blocks their path. Charging at his opponent, Hyoga's "Diamond Dust" is reflected by the Gold Saint who is not even moving.
Amazed at the power of the Gold Saint, Hyoga burns his Cosmo and unleash his "Aurora Thunder Attack", but that attack is also deflected, knocking Hyoga out after receiving both "Diamond Dust" and "Aurora Thunder Attack" reflected by Gemini. As Hyoga lies unconcsious, the Gemini Saint unleash his own attack "Another Dimension" at the two Bronze Saints, sending them to an infinite space corridor. Shun manages to return to the House because of his chains, but he is unable to save Hyoga who flies further away.
House of Libra
As Shun manage to defeat the Gemini Gold Saint, Hyoga recovers at the House of Libra where he encounters Crystal Saint's master Camus. Failing to have Hyoga raise his fist and fight back against the Gold Saint, Camus sinks the ship where Narissa lies, in order to have Hyoga finally attack.
As Hyoga feels his mother sinking further down the ocean, the Cygnus retaliates in anger against Camus, but his attacks are easily defeated as Camus is Crystal Saint's master, thus making him the one who truly created "Diamond Dust" and "Aurora Thunder Attack". Seeing that Hyoga has failed to awaken his 7th sense, Camus unleash his "Aurora Execution" before trapping Hyoga in a everlasting "Freezing Coffin".
Later, the other Bronze Saints arrived after passing through the House of Virgo and found their friend at last, frozen in the coffin. With the aid of the Libra Cloth, Shiryu freed Hyoga from the coffin and Shun remained at the House of Libra to revive him with his Cosmo.
House of Scorpio
Recovering, Hyoga carried Shun who was exhausted and the two made way the House of Scorpio where Seiya and Shiryu fought a desperate battle against Miro before being easily defeated by the Gold Saint.
Arriving with an unconcsious Shun, Hyoga urges the two Bronze Saints to bring Shun and move ahead, freezing Miro with the "Kolitso". As the Bronze Saints leave, Miro easily neutralize the "Kolitso", taunting Hyoga that a weak technique like that would never restrain a Gold Saint. Hyoga simply replise with having used it in order to buy some time for the Bronze Saint.
After a brief conversation, the two Saints clash in what at first seems to be an equal match, with Hyoga managing to freeze Miro. However, the Gold Saint simply breaks the ice, and before Hyoga can land another blow, he is suddenly struck by pain in his shoulder. Retaliating against Miro, Hyoga is instead inflicted by several more impacts of the "Scarlet Needle", receiving 14 of 15 during their battle.
Refusing to give up, even after Miro states he will let Hyoga live due to him being Camus' student, Hyoga retaliates against Miro, seemingly landing a powerful blow. The impact, however, leaves Miro unharmed due to Hyoga's weakening from the "Scarlet Needle". However, as the two Saints decide to end the battle, Hyoga manages to awaken his 7th sense and the two clash. As Miro unleash the "Scarlet Needle Antares", Hyoga manages in the last second to launch a "Diamond Dust" which freeze all of Miro's star points. Although Miro wins his life due to his Gold Cloth, the battle was a loss for him.
Hyoga, however, still crawls onward in order to rendezvous with Seiya and the others as he promised. Miro, touched by Hyoga's true loyalty, and realizing that the one the Bronze Saints fight for truly is Athena, he neutralize the effect of the "Antares", before allowing Hyoga to move onward.
House of Sagittarius
Regrouping with Seiya, Shiryu and Shun, the Bronze Saints try to pass through the House of Sagittarius, but they instead end up facing several obstacles that prove challenging for them. They do manage to pass through eventually, finding Aioros' message which says "Young warriors. I entrust Athena to you". With a renewed promise to save their goddess, the Bronze Saints resume and pass through the House.
House of Capricorn
Arriving at the House of Capricorn, the Bronze Saints notice a statue of Athena, handing the legendary sword Excalibur to one of her most loyal warriors, before passing through relatively easy, meeting no resistance inside. However, the ground starts to split, prompting Shiryu to push the others to the other side, remaining at the House where he meets Shura.
With no other choice, the Bronze Saints resume their journey until they notice Shiryu soaring into the heavens, sacrificing himself in order to defeat Shura.
House of Aquarius
Having little time to mourn Shiryu's sacrifice, the Bronze Saints encounter Camus. Sending Seiya and Shun ahead, Hyoga remains at the House of Aquarius in order to settle things with his master.
Starting of as a one-sided battle, Hyoga's attacks are once more reflected, leaving the Cygnus wounded after each attempt and both his legs frozen. As Camus ask the Bronze Saint about the Absolute Zero, Hyoga remembers Crystal Saint teaching him all the basics of mastering the cold and freezing atoms, informing him of the Absolute Zero at the same time.
Once more being wounded by Camus' lightspeed blows, Hyoga receives the "Aurora Execution" once more. However, the Bronze Saint stand up this time and retaliates with his "Aurora Thunder Attack", which is easily deflected by the Gold Saint who then proceeds to trap Hyoga in the "Freezing Coffin" once more.
Remembering Shiryu and Shun saving him as well as Shiryu sacrificing himself in order to allow the others to move ahead, Hyoga burns his Cosmo to the maximum, shattering the coffin and surprising Camus. Standing up once more, Hyoga launch a powerful blow at Camus, who retaliates. As the two Saints clash, Camus is surprised to see that Hyoga's coldness equals his own, but soon discovers that Hyoga lost concsiousness as they clashed.
Hearing Athena's and his friends' voices, Hyoga manages to recover and gathers their energy, shattering his Bronze Cloth before sending the full blast at Camus, which knocks his tiara off and freezes his right shoulderplate, covering the entire House in ice.
As Camus prepares to end the battle with the "Aurora Execution", Hyoga suddenly take the same stance as Camus, mimicing the attack. Burning their Cosmo to the maximum, the two Saints clash with their "Aurora Execution", which ends in a draw as Hyoga falls unconcsious and Camus succumbs to his wounds and dies, having been overpowered by Hyoga who reached the 7th sense and mastered the Absolute Zero.
Final battle against Saga
He would in the end arrive at the final battle between Seiya and Saga, burning his Cosmo to the maximum and, with the other Saints, transfer their Cosmo to Seiya and help defeat Saga.
After the battle against the Gold Saints, as Hyoga's Cloth was shattered, and were in need of repairs, his Cloth was resurrected by the blood of Miro and had now the endurance of a Gold Cloth.
After Seiya manages to defeat Thor, the Bronze Saints split up in order to find the God Warriors and retrieve their Odin Sapphires which will allow them to use the Balmung Sword in order to destroy the Nibelungen Ring.
During Shiryu's battle with Fenrir, Hyoga encounters the God Warrior Hagen who seems to have a massive Cosmo. Realizing that if he would burn his Cosmo to the 7th sense, Hagen would not be so hard to handle, and burns his Cosmo which seem to impress the God Warrior as the two combatants Cosmo clash.
Attacking the God Warrior with his "Diamond Dust", Hyoga manages to freeze him but Hagen simply breaks loose from the ice and deflects Hyoga's second attempt with the same technique. Unleashing his "Universe Freezing", Hagen seems to defeat Hyoga by placing him in a large wall of ice, Hyoga simply laughs and breaks free from the ice with little effort. As Hyoga mentions Freya, Hagen attacks the Cygnus in rage, swearing to kill him in order to please Freya. Once more burning their Cosmo intense, the two clash as Hyoga use his "Aurora Thunder Attack" and Hagen retaliates with the "Great Ardent Pressure", which to Hyoga's shock is a fire technique. Revealing that he trained in the cold lands of Asgard and was given the God Robe which allowed control over fire, Hagen retreats into a mysterious cave.
Pursuing the God Warrior, Hyoga notice that the cave is filled with lava and wonders how that is possible in such an icy region as Asgard. Refusing to accept defeat in spite of being in an area which is to hot for him, Hyoga once more challenge Hagen who starts to gain the advantage, due to the intense heat from the lava which seems to have no effect on the God Warrior.
On the verge of defeat, Hyoga is unable to hold of Hagen's assaults and is knocked unconscious as he is able to see the trace of Hagen's attack. As Freya intervines and stand between the two, Hagen reluctantly sends another blast against Freya and Hyoga, but Hyoga quickly swaps sides with Freya, taking the full blast himself as the two are launched against the wall.
As Hyoga is furious at Hagen for raising his fist against his childhood friend, he burns his Cosmo to the maximum. Hagen, in retaliation, burns his own Cosmo out of anger for Hyoga daring to tell Freya that Asgard is evil. The two clash once more, with Hyoga reaching his 7th sense and using his "Aurora Execution", which overpowers Hagen's "Great Ardent Pressure", and the God Warriors dies from the impact of the blow.
Seconds later, Freya recovers and mourns her childhood friend's death and Kiki arrives, before they bury Hagen outside the cave.
Sensing Seiya's Cosmo disappearing, Hyoga heads for the forest where he encounters Alberich who just defeated Seiya and trapped him in an amethyst. Furious at the God Warrior, Hyoga burns his Cosmo and swears to rescue Seiya and Marin by defeating Alberich. As the God Warrior charge with his sword, Hyoga attempts to freeze it with his "Diamond Dust", but the attempt is unsuccesful and Alberich easily breaks the ice on his sword, once more charging at Hyoga with several slashes. As Hyoga attempts to freeze the God Warrior's feet, he is cut in the back by Alberich sword before he use the flames to thaw the ice on his feet. Attacking the Cygnus again, he is instead delievered a punch to the stomach in which he drops his sword.
Fleeing further into the forest with Hyoga in pursuit, Alberich unleash his family technique "Nature Unity" which grants him the upper hand as Hyoga is unable to fight back against the violent attacks of the trees, and is further wounded by the God Warrior's merciless attacks.
Grievously wounded and unable to fight back, Hyoga is almost defeated by Alberich as he unleash his "Amethyst Shield", but he is saved by the timely arrival of Shiryu who engage Alberich in Hyoga's place.
Arriving at the Valhalla Palace along with Seiya, the two Bronze Saints encounter Shun who is struggling against Syd. As Seiya and Syd prepare to clash, Shun intervines and urges them to move ahead while he dealt with the God Warrior on his own. Leaving Syd to Shun, the two Bronze Saints move on and encounter a large wall which Seiya easily breaks.
However, the wall suddenly unleash a powerful gust of wind which knock the two unconcsious. Recovering from the blast, Hyoga burns his Cosmo and freeze the large pieces of the wall in order to allow Seiya passage. However, the pressure is to much and Hyoga once more collapse, due to being exhausted.
Later, he would reunite with Shun and Ikki who finally managed to defeat Syd and Bud before moving onward to rendezvous with Seiya. Refusing to leave their friend behind, Ikki urges Hyoga to stand up and grab his hand, which the Cygnus does.
Carried by Shun and Ikki, the three Bronze Saints make way to the statue of Odin, where Siegfried defeats Seiya, prompting Ikki to challenge the God Warrior. As they witness the brutal battle between the two combatants, they are horrified as Ikki is defeated by Siegfried before the God Warrior attacks the two Bronze Saints and knock them unconcsious as well.
Once more standing up as Siegfried gave his life to destroy Sorrento who arrived at the scene, Hyoga would accompany Shiryu, Shun and Ikki in order to defend Seiya with their lives as he tried to reach the Statue of Odin and ask for the Balmung Sword.
Making way back to Athena, they find their Goddess unconcsious, and they are joyful when they see her standing up, still alive. As they have a brief moment of reunion, a large wave suddenly strikes the Saints, and as they recover, they notice Athena is gone.
Arriving at the North Pacific Ocean's Mammoth Pillar, Hyoga witness as Seiya engage Baian in a final fight, emerging victorius after awakening his 7th sense. As Shiryu rendezvous with them as well, Seiya informs the two that they must destroy all the 7 Mammoth Pillar supporting the ocean in order to rescue Athena.
With that in mind, Shiryu and Hyoga split up, heading for separate Mammoth Pillars.
Antartic Ocean's Mammoth Pillar
Hyoga arrived at the Arctic Ocean Mammoth Pillar, where he was greeted by Camus. At first, he attacked the Gold Saint as he was convinced Camus died during their battle at the 11th Temple, but after receiving the "Aurora Execution" attack, he was convinced that it really was Camus standing in front of him. However, it was later revealed to be an illusion, and Hyoga was severly wounded.
Arctic Ocean's Mammoth Pillar
After being revived by Ikki, Hyoga made his way to the Antarctic Ocean Mammoth Pillar. Arriving there, Hyoga was met by a cold and powerful Cosmo, meeting the Marina General guarding the Pillar. Unsure at first who the General was, Hyoga demanded that he reveal his face, in which the General does. To Hyoga's shock, the General reveals himself as Isaac, his former training partner from when they were both young and about to train in order to become Saints.
Now the Marine General protecting the Pillar, Isaac attacks Hyoga mercilessly, no longer caring for the past friendship they had when they were younger. Stating that he was now one of Poseidon's Marina Generals and Hyoga was one of Athena's Saints, they were therefore enemies and only one would emerge alive from the unescapable battle.
Wounding Hyoga's left eye, Isaac later unleash his "Aurora Borealis" which further damage Hyoga. Not wanting to fight back against his former partner and friend, Hyoga simply allows Isaac to unleash his Cosmo without retaliating.
However, as Hyoga lies unconcsious, Kiki arrives with the Libra Cloth and is confronted by Isaac who decide to destroy the Gold Cloth. Refusing to hand it over, Kiki tries to attack Isaac with his psykokinesis, but is easily defeated. Holding tight to the Libra Cloth, Kiki is further wounded as Isaac tries to kill the Appendix.
Standing up once more, Hyoga simply approach Kiki and assures him that he will defeat Isaac and then destroy the Mammoth Pillar. Retaliating against the General with his "Diamond Dust", Hyoga starts to equal Isaac's strength with little effort, blocking his "Aurora Borealis" as well as turning his own Cloth golden, due to the Cloth having been revived by Miro's blood and Cosmo. Neutralizing Isaac's attack, Hyoga burns his Cosmo to the 7th sense and unleash his "Aurora Execution", with Isaac retaliating once more with the "Aurora Borealis". As the two ice warriors clash one last time, Hyoga's Cosmo manage to overpower Isaac, damaging his Scale and grievously wounding him.
As Isaac was dying, he revealed the true mastermind behind Poseidon's plans as a man they all knew well. Shocked at hearing who that man was, Hyoga asks Isaac further but to no avail, as Isaac has succumbed to his wounds.
Throne Room of Poseidon
When Hyoga arrived at the throne room, he saw a defeated Seiya and Shiryu who was struggling against Poseidon. Before he could get the chance to attack, Poseidon tried to kill Hyoga, but Shiryu stepped between, blocking the blast for a little while with his shield before breaking due to the massive impact, wounding the three Bronze Saints. After Seiya managed to shoot Poseidon, the Saints made way for the Main Breadwinner to save Athena.
Before they reached the Main Breadwinner, Poseidon attacked again and Hyoga received the Aquarius Gold Cloth to help fight Poseidon, althoug his attack was easily reflected even in spite of wearing a Gold Cloth.
In the end, he and his friends burned their Cosmo to protect Athena, surpassing Poseidon and sealing the Sea God.
After the battle against Poseidon, peace roamed for a little while, until the seal holding Hades and his 108 Specters for 243 years wore out, and thus, a new Holy War had begun between Athena and her Saints against Hades and his Specters.
Hyoga makes his appearance when the Silver Saints Misty, Babel and Moses arrives in Siberia to kill him, but were defeated very quick by his strong Cosmo. Hyoga would appear at Sanctuary with Shun and find out what is going on.
House of Aries
When they arrived, the House of Aries was damaged after a great Cosmo explosion after the batlle between Shion and Dohko, and they reuinted with Shiryu, before they finally found Seiya and headed onward towards Athena.
House of Virgo
When they arrived at the House of Virgo along with Aioria, they were grieved by the loss of Shaka after the battle against the three former Gold Saints who used the "Athena Exclamation". As the three former Gold Saints reveal themselves to Aioria, Mu and the Bronze Saints, Miro arrives and after a brief confrontation, the Gold Saints and the former Gold Saints clash with the "Athena Exclamation", which the Bronze Saints manage to neutralize after burning their Cosmo to the maximum, using their own techniques in order to send the "Athena Exclamation" soaring to the sky where it explodes, leaving the Sanctuary unharmed.
Statue of Athena
Recovering from the blast, the Bronze Saints try their best to reach the statue of Athena, but due to being exhausted and wounded from the confrontation at the House of Virgo, they are unable to make it in time, feeling Athena's Cosmo disappear as she takes her own life.
As they arrive at the statue, they notice the golden dagger and Athena's blood, lamenting on being useless. Just then, Shion arrives and insults the Bronze Saints in being useless and only Saints in title. Attacking the former Pope with their remaining strength, the four Bronze Saints are easily defeated.
Listening to what Shion has to say, the Bronze Saints realize that even in death the Saints would never betray Athena and all their actions so far was in order for Athena to prepare herself to defeat Hades in the underworld.
Using Athena's blood, Shion restores Athena's Cloth which will be crucial for Athena if she is to win the Holy War. As he informs the Bronze Saints to defeat Hades, he bestows their Bronze Cloths with the same blood, awakening to their most powerful form.
As Shion entrust Athena to them, the Bronze Saints then head on to join Aioria, Mu and Miro who went on ahead to the earthly castle of Hades.
Arriving at the castle, they challenge Rhadamanthys, one of the 3 Judges of Hell, but the Gold Saints send them on ahead as they would not be a match for the Wyvern. Sacrificing themselves, the Gold Saints launch their final techniques as Rhadamanthys, but all three of them are defeated.
As the Bronze Saints encounter Shura, Saga and Camus who are slowly dying due to their temporarily life reaching an end, Hyoga unleash the "Aurora Execution" against Zelos in retaliation for the Specter stomping on Hyoga's master.
Hearing a harp, they rush to see who's playing, and notice Rhadamanthys unharmed, who states that he has killed all three Gold Saints. Refusing to let the Judge mock the Gold Saints and wanting revenge for their comrades, the Bronze Saints charge at the Specter, but they are all easily defeated one by one.
Refusing to let him kill Seiya, the Bronze Saints once more burn their Cosmo and attack the Judge, but he retaliates with the "Greatest Caution", knocking them all unconcsious. As Seiya plunge down to the underworld with Rhadamanthys, the other Bronze Saints recover.
Preparing to follow Seiya into the underworld, the Bronze Saints are interrupted by the arrival of Dohko who informs them of the 8th sense which is neccesary in order to reach the underworld without being subject to its laws. Believing them able to reach that Cosmo due to their vicious battles, Dohko urge them to burn their Cosmo and believe in themselves.
When they finally arrive in the underworld, Hyoga teams up with Shiryu and eventally Kanon, charging through the prisons, one by one, defeating all Specters in their way. Later, they would reach a large river which they had to cross, also encountering the ferryman Phlegyas who easily defeats the two Bronze Saints, before being eliminated by Kanon seconds later.
Eventually, as they resumed their journey, they would encounter Rhadamanthys again who informs the three Saints that Shun has revealed himself as Hades himself. Trying to eliminate the Bronze Saints, the Judge is interrupted by Kanon who sends the two teenagers ahead.
The Wall of Grief
The two Bronze Saints finally reach Giudecca moments after Kanon sacrifice himself in order to defeat Rhadamanthys, and would rendezvous with Seiya and Shun again as well as a warm reuninon with the Gold Saints
Urging the Bronze Saints to leave, the Gold Saints sacrifice themselves to destroy the Wall of Grief. After that, Hyoga would face Minos, giving Seiya and Shun time to reach Elysion, and took his "Cosmic Marionetion" on purpose, before seriously wounding him with the "Aurora Excution". Jumping after Seiya and Shun, Hyoga notice one of Minos' strings still attached and watches in shock as Minos is crushed by the atmosphere, realizing that their Cloths born from the blood of Athena protects them. As Minos is vaporized, Hyoga waits for Shiryu to arrive, later taking flight with the Dragon to Elysium after sprouting his Cygnus wings.
In Elysium, he would be the third Bronze Saint to arrive and attack Thanatos, but was defeated as easily as Shiryu and Shun. Hyoga and Shiryu would be the third and fourth to receive their God Cloths and defeat Hypnos, before finally defeating Hades. to Elysium where they try in vain to defeat Thanatos who easily deflects their attacks and cracks their Cloths. As they are given the Gold Cloths to fight with, they are also easily destroyed and they are left without hope.
However, they are shocked as Seiya is clad in new armor once again which finally allows him to defeat Thanatos who dies of his wounds shortly after. As Hypnos stands in Seiya's way, Shun attempts to fight the god of sleep, but is defeated. Drawing Hypnos' attention, Shiryu and Hyoga also awaken their God Cloths, before charging at the god. As he deflects their attacks, they seems close to defeat too, but they manage to evade his attack and retaliate, wounding Hypnos greatly.
As they hear a loud explosion, Hypnos taunts them about their unescapable fate as he succumbs to his wounds. Rushing to the grave of Hades, they arrive in time to help Seiya and Ikki fight Hades, but they are all reflected with no effort by the god of the Underworld.
However, as Seiya sacrifice himself to defend Athena, the other Bronze Saints gather their Cosmo to Athena and they are able to finally destroy him and claim victory in the Holy War.
Hyoga's Cosmo allows him to control ice and freeze his opponents. During the battle against Miro, he managed to awaken his 7th sense for the first time, freezing all of Miro's weak points which would have proven lethal for him if not for the Gold Cloth.
Hyoga has also reached the Absolute Zero, surpassing even his own master, Camus.
During the battle against Hades, Hyoga awoke his 8th sense, allowing him to travel to the World of the Dead without being subject to it's laws. Whenever Hyoga burns his Cosmo, he is surrounded by a white aura.
Diamond Dust: Hyoga concentrates his Cosmo into one punch with a huge coldness and freezing his opponent. The blow concentrates wind and ice into one, single point.
Aurora Thunder Attack: If his Diamond Dust is useless against his opponent, Hyoga will use the Aurora Thunder Attack, where he clasps his hands together and expels ice and snow at the opponent. This technique is much more powerful than the Diamond Dust.
Kalitso (Frozen Ring): Hyoga traps his opponent in a ring of ice that immobilize him. He has used it twice in the anime, first on Black Cygnus during their confrontation in the forest, later against Miro at the House of Scorpio.
Freezing Coffin: Although not as powerful as Camus', during the Hades Chapter, Hyoga made a wall of ice which was said to be unbreakable by even all twelve Gold Saints, but it was easily destroyed in one hit by Minos.
Aurora Execution: Hyoga's strongest attack. Pretty similar to the Aurora Thunder Attack, he clasps his hands together and covers his enemy in snow and ice. He learned this attack when he faced Camus in the 11th temple, as he reached his 7th sense.
Hyoga's Cloth has changed shape a few times
Hyoga's first Cloth has a white color and offers leg protection up to the knees, a skirt to protect his waist, the chesplate covers his upper chest, a tiara with the shape of a swan covers his head and his lower arms are halfway guarded. On his left arm is a shield with good defence properties, although not as strong as Shiryu's shield. The swan on the tiara has a yellow beak and red eyes.
Hyoga's second Cloth covers less of his body. The leg protection covers half of his lower legs, the skirt has been replaced by a belt, while the rest of the Cloth offers the same decent amount as before.
Hyoga's Cloth that was reborn by Athena once more covers the young Cygnus Saint. His body is also more protected now, as the belt becomes a small skirt that covers both sides and his back on the waist, the chestplate changes in design, and the legs receive more protection. On the way to Elysium, Hyoga discovers that his Cloth has wings, which he uses to bring himself and Shiryu onward, to rendevouz with Seiya and Shun.
Hyoga's God Cloth was awakened as he and Shiryu fought against Hypnos. Hyoga's God Cloth covers almost 100% of his body with gold engravements on the Cloth, and large wings appears on his back. While wearing this Cloth, Hyoga is surrounded by a divine aura when he burns his Cosmo.
Aquarius Gold Cloth
As Hyoga is the student of Camus, Hyoga is given the right to wear the Aquarius Cloth in times of need. The Cloth covers his lower arms, most of his legs, his chestplate is fully covered and his head is protected by a tiara. While burning his Cosmo, Hyoga's aura change from white to a golden yellow.
- Several times during Hyoga's battles, the swan has one blue eye and one red.
- During the battle against Poseidon, the Aquarius Cloth equips itself on Hyoga. While that happens, the leg armor of the Gold Cloth wrap themselves over the leg armor from his shattered Bronze Cloth.
- Among the main characters, Hyoga is one of the five Bronze Saints who receive a color change on his garb (blue, later white)
