Pegasus Kōga (天馬座（ペガサス）の光牙, Pegasasu no Kōga) is the Bronze Saint of the Pegasus constellation in Saint Seiya Omega. Koga can use the element of Light but his real Cosmo element is Darkness. After Abzu's defeat, Koga's true Cosmo element is Light again.
He hates to lose, so he is always struggling, despite having a big heart. He never gives up and protects his friends, no matter what happens to himself, is very sentimental, but does not want to show it in public. He has a strong rebellious spirit at first, but also has a sharp understanding of most any given situation, making him a good leader.
The newborn Kouga and Aria were found at the site of the crater having been bathed in Darkness and Light Cosmos. Kido Saori managed to take Kouga while Mars grabbed Aria. Realizing that the baby boy would have a harsh destiny because of the Darkness Cosmo inside of him, she decided to raise and bathe him in her own Light Cosmo in hopes that it would lead the child to a better future.
Several months after being born, as the baby Kôga learned how to walk, Mars returned, clad in a new armor called "Galaxy", to take Athena. In her effort to protect the child, Kido Saori was wounded by Mars' Darkness which prevented her from properly burning her own Cosmo, however before the God of War could take her, Seiya arrived to save them both. The young Kouga watched in awe as Mars and Seiya fought each other with all they had, ending up with the former severely wounded and the latter no where to be found.
Training to become a SaintEditKouga was raised by Saori on a remote island along with Tatsumi and Ophiuchus Shaina (Omega). Despite the young man's unwillingness, Kouga spent a good portion of his young life going through the rigorous training to become a Saint. Dissatisfied with what he felt was a future he had never chosen, Kouga started to question why did he needed to protect Athena, unaware that he was talking about Saori, and even made light of the sacrifice that Sagittarius Seiya made for him many years ago. Aware of the young man's troubling thoughts, Saori tried her best to sooth his mind by telling him that becoming a Saint will give Kouga the strength to protect what's precious to him. Kouga is still not convinced, but comments about having a dream of a man covered in gold and wonder if that was Seiya. At this Saori tells Kouga that things will become clear to him once he becomes a Saint and gives him her pendant saying that it is a very precious item.
Koga first confrontation with MarsEdit
Unfortunately, the moment is cut short by the arrival of Mars, who has spent the last 13 years recuperating from his fight with Seiya and has now return to take Athena. In an effort to protect Kouga, Saori reveals herself as Athena to him, but the Darkness Wound Mars inflicted years prior prevents her from properly using her Cosmo. Shaina arrives and tries to fight Mars, but she is quickly defeated by the God of Wars. At that point, Kouga desperation to protect Saori causes the pendant to react and grant the young man the Pegasus Cloth Stones, surprising Mars as he sees a shadow of Seiya in the boy. Clad in the Pegasus Cloth, Kouga has a vision of Seiya guiding him to burn his Cosmo, which allows the new Saint to unleash a powerful Pegasus Ryu Sei Ken that manages to push Mars' Cosmo back.
Sadly, Kouga's new found power was not strong enough and Mars immediately regained the upper-hand, beating Koga and destroying a large portion of the island in the processes. The next day, Kouga informs Shaina that he is planning to leave the island and search for Saori. Shaina accepts the boy's wishes, saying that the Pegasus Clothstone, the pendant Saori left him, will surely show him the way. Tatsumi then takes Kouga to the mainland and bids him far-well. Soon after setting out, a young man recognizes Kouga's pendant as a Clothstone and excitedly as if he's a Saint as well.
The search for SaoriEdit
Taken by surprise, Kouga reacts aggressively at the newcomer which leads to a small confrontation, ending with Kouga being coincidentally knocked out. Once Kouga regains consciousness, the young man presents himself as Lionet Sōma and ask for redhead's name and title, showing great surprise when he find out that Kouga inherited the Pegasus Clothstone which used to belong to the Legendary Saint, Seiya. After Souma briefly explains why the Elemental Cosmo works, Kouga tells his new friend about his journey to find Athena.
Souma is not ready to believe the redhead and decides to check a place where Athena was suppose to be living in, unknowingly taking Kouga back to the island. Not being able to find any news about Athena's whereabouts, Souma decides that there might be some truth to Pegasus Saint's story and decides to take him to a place where they are sure to find out the truth about Athena, the school of Saint, the Palaestra. As the two young Saints start to make their way to the school, the get attack by the Martian, a member of Mars' forces,Mantis Ordykia who manages to capture them both in his Darkness Cosmo.

Despite of worried, Kouga told Saori that everything will be fine. He will return soon after he finish Abzu. After Kouga asked Saori to leaved, Abzu came and fight Kouga again. Suddenly the Aria holy stuff appeared in front of Kouga facing up to Abzu. This time Aria stuff releasing a huge energy blast containing Athena's light replacing the darkness surround. Abzu dark cosmos depleted. And while being shocked, Kouga launch his final punch with all elemental with it and destroying Abzu once and for all.

Yuna and the gang looked up in they sky that Mars is being pushed back to the place and restored earth back to normal. Yuna questioning about Kouga whether he is still alive. But Seiya give the look and not know how to respond.
Back after the debris of the explosion, Kouga floated in space. Despite of this, he woke up and saw Aria for the last time.

Souma and yuna did a combo while shun use his chain to send kouga to the barrier. Kouga depowered himself to get in and punched surt. Surt was then defeated by shun. Koga, Souma, Yuna, and Shun encounter the Pallasite First Class Aegaeon who wants to test the Bronze Saints' powers himself. After telling the Saints about how Ikki put his life on the line to crack Aegaeon's sword, Shun has a hard time fighting him until Koga, Souma, and Yuna keep fighting the Pallasite, defending Shun. Burning his Cosmo to the maximum, Koga manages to give Aegaeon a crack to his sword, before Ikki arrives to save the Bronze Saints, taking over the battle. Koga and Friend face off against Gallia on their own, allowing the Gold Saints and Athena to move forward towards Pallas. Although Gallia's Photontector and Bushin Photon Sword seem impervious to harm, Subaru once more calls on the mysterious powerful Cosmo to break through Gallia's offensive and actually damage the sword, convincing the others to call upon their own osmo, transforming their New Cloths into the more powerful Omega Cloths, and together the six Bronze Saints defeat Gallia.
Koga,Souma,Yuna,Ryuho,Haruto,Eden and Subaru investigate what they believe to be the final resting place of Shiryu, Kiki, and Fudou, who sacrificed themselves to defeat Hyperion, but they discover that while the Tenchi Destruction Slash has been destroyed, Hyperion has survived with barely a scratch. Koga and his friends must use their new Omega Cloths to take down Hyperion for good. During the battle, Subaru's great and powerful Cosmo once again surfaces to everyone's surprise, along with the proclamation that he is a god. However, after seemingly defeating Hyperion, a strange voice talks to him from within and he starts to lose it until Hyperion launches Subaru into a wall, stealing his time with the Chrono Destruction, horrifying Koga and the others.
As Subaru's time is taken away by the Chrono Destruction, Koga, Yuna, Souma, Ryuhou, Haruto, and Eden confront Hyperion while Subaru's mind awakens in an unknown place, greeted by a mysterious figure. Meanwhile, his friends keep fighting to protect Subaru despite Hyperion attacks them with full power, until they finally attain the true power of Ultimate Omega cloth by elevating their Cosmo to the next level, the Macro Cosmo. Donning their new Omega Cloths, the Saints overpower Hyperion and guided by their light, Subaru returns to life. However, once the Pallasite is defeated for good, the shadow following Subaru warns him of the risks of mere humans attaining a power equal to the gods before leaving, and Subaru recognizes the mysterious figure as himself, much to his astonishment.

- Pegasus Ryūsei Ken (Pegasus Meteor Fist) : Kouga performs hundreds of punches at the same time which makes it look like small meteors. As Seiya's signature technique, Kouga first witnessed Seiya using it as a baby, and would learn this technique the first time he donned the Pegasus Cloth, instinctively performing it after seeing a vision of Seiya telling him to burn his Cosmo. Kouga has problems using this technique until Geki's words about how Seiya never giving up helped him to stand back up.
- Pegasus Senkō Ken (Pegasus Flash Fist): Kouga gathers his light cosmo into his fist and then punches his opponent with the charged energy. The impact lets out a blinding flash of light. A technique developed by Kouga himself during his fight with Ryuho after the Dragon Saint pushed him to fire up his Cosmo.
- Pegasus Sui Sei Ken (Pegasus Comet Fist): Kouga charges up his light cosmo in his right hand and create a powerful homing ray of pure light.Kouga used it during his fight with Capricorn Ionia after he awakened to his seventh sense.
- Pegasus Ryusei Ken (All elemental combined) : The same technique he used to delivered hundreds or more meteor punches to the opponents. But far more powerful. Thanks to Kouga's dark and light elements combined with other bronze's saints five elements (Fire, wind, thunder, earth, water) and raised the cosmos to reach seven senses, which was stored to his broken right hand. The hundred meteor punches is glowing bright orange auras despite the normal blue light meteor punch (normal Pegasus Ryusei ken). This techniques is used against Abzu at the end of the final battle.
- Pegasus Rolling Crush : A new technique learned by Koga, he first immobilize his target physically then form a hurricane of light while rising through the air and then dropping his target on the head.
Predecessors and successorsEdit
Main Article: Pegasus Seiya
- Kouga means "light fang", however this is ironic since his true element for most of his life was darkness. This is made more feasible since the first name of his seiyuu, Hikaru, originates from the same stem as hikari, meaning "light". After he was unposessed by Abzu, Kouga lost all traces of his darkness element, his true element becoming light.
- Kouga is the first known Pegasus Saint who was not a reincarnation of a previous one.
- Like Seiya before him, Kouga was forced to use the Sagittarius cloth when the Pegasus cloth was too damaged to keep using, although his time wearing the cloth was considerably shorter, in addition to the cloth being already heavily damaged.
- He is the second Saint to host a major antagonist. The first was Shun during the Hades Chapter, although unlike Shun, however, Koga was not Abzu's reincarnation.
