Libra Dōko

Libra Dohko (天秤座の童虎, Raibura no Dōko) is one of the Gold Saints. He is one of the oldest characters in the manga next to Aries Shion, as they both appear in the previous Holy War, and is most known by his role as Dragon Shiryu's mentor. He is also referred to as Old Master (老師, rōshi) by all of the Saints of Athena as a sign of respect, even though his only true student is Shiryu.

Personality and background
Dohko is one of the two survivors of the last generation of Athena Saints along with Aries Shion who is a close friend of him. After the war, Dohko received the order to watch the tower where Hades' Specters were sealed until the next Holy War. Dohko lives at the Five Peaks in China alone with Shunrei, an orphan girl he took on his care. Dohko is also the master of Dragon Shiryu and Ohko, who is an anime-only character. Dohko represents a father figure to Shiryu as well, and Shiryu often recalls on his wise teachings whenever facing difficulty in battle. He is often seen as an adviser of the main characters and a good friend of Aries Mu, Shion's disciple. When Dohko was young, he was much more vivid and rather impulsive. After regaining his young form during the Hades arc, he retains the behavior of his youth, albeit much more circumspect and mindful, result of his almost three centuries of experience as a Saint.

Plot ( Episode G)
Apart from being mentioned by Taurus Aldebaran in the meeting golden Dohko so far has had a moderate participation. First appeared in a vision of the future where it shows next to Shunrei and Dragon Shiryu at Rozan. In Gaiden, stars alongside Aries Shion, one in which shows the end of the previous Holy War. His biggest turnout was in a fight with Leo Aiolia against Pontos, God does not understand how Aioria exceeded the speed of light, as this can only be achieved if the divine power, but this makes Aioria effort reaches its limit, right time for Titans to end Saint Leo once and for all. When the Titan was going to end the holy Libra Shield protects you and the great master of Libra Dohko five peaks appeared with his young appearance. Aioria Dohko explains that he can not really move but if you send five peaks cosmos with an illusion of your body to fight against the Titan. The illusion could Aioria protected while and made him remember to trust the great strength of his companions, after that we see in Aries Mu Jamir who raises their cosmos and use his powers to teleport to other Leo Aioria.

Aftermath
As he became one of the survivors of the ancient Hades War, after the war, Shion was assigned to be the pope of the Sanctuary while Dohko was assigned to guard the seal of Hades. (see Suspended animation ) Dohko on the other hand received a miraculous ability known as Misopetha-Menos, a way to preserve youth indefinitely (some animals are capable of doing this for a short time, in Dohko's case it will need this Misopetha-Menos spell). As a normal person has about 100,000 heartbeats per day, Dohko has about 100,000 heartbeats per year with the help of the Misopetha-Menos. Relatively speaking, the 243 years is a mere 243 days for Dohko. This enabled Dohko to live a long life, shrunk from his normal average human size to the one of an old purple man. The condition was that Dohko must stay in the Mount Lu as a watchguard. As the time Hades will be unsealed, Dohko can be prepared to fight off Hades and his Spectres with his youthful body. This divine gift is a secret that even Shion, the former Pope, was unaware of. It is also for this reason that he is exempted from mandatory meetings in the Sanctuary.

The Sanctuary arc
Dohko is Dragon Shiryu's Teacher, but Shiryu didn't know about Dohko's past, until Cancer Deathmask came to Mount Lu in an attempt to take the Libra Gold Cloth from him, revealing that he is one of the 12 Gold Saints of Sanctuary. It was implied that Dohko distanced himself from Sanctuary due to his suspicion that his old friend Aries Shion, the Pope of the Sanctuary, has been replaced. During the incoming fight, Dohko wasn't able to help directly the Bronze Saints, but sent his Gold Cloth to Shiryu so he could free Cygnus Hyoga from Aquarius Camus' Freezing Coffin. He also saved Shunrei from drowning when Cancer Deathmask struck her with a telekinetic attack as a gesture to taunt Shiryu.

The Asgard and Poseidon arcs
During Athena's departure from Sanctuary, Dohko, acting as the highest command aside from Athena and the Pope, ordered all of the Gold Saints to remain in Sanctuary to prepare for a greater battle that is ahead. However, his spiritual guidance has helped Shiryu overcome many enemies, especially against Megrez Delta Alberich, in the anime-only Asgard saga. To aid the Bronze Saints in the battle against Poseidon, he also ordered Kiki to deliver the Libra Gold Cloth to them, which helped them destroy the Pillars of the Seven Oceans.

Plot (Hades arc)


His most prominent appearance is in the Hades chapter, when he felt that the Hades seal finally broke, so he goes to the Sanctuary to fight against Hades, and then turns on the fire clock. Hades revives some dead Saints, including Aries Shion, the former pope. Shion and Dokho meet again, and eventually the two fight. During the fight Dohko attempts to use his supreme attack, the Mount Lu One Hundred Dragons Wave to defeat Shion, but it failed to defeat him. Shion stated that Dohko, being 243 years older, could not possibly stand a chance against him, having his youth restored by Hades. He proceeds to defeat Dohko, but just the moment Dohko want to die with Shiryu together, the Libra Cloth appears before Dohko and defends him. Unlocking the memories of wearing the Libra Cloth, he then breaks the power of longevity and turns back to his original young form to be able to fight properly. His purple skin has gone. The tiger image reappears on Dohko's back and is now evenly matched with his former friend. Dohko wants Shiryu to go to join the Gold Saints and apologizes to Athena for the coming because she had not allowed Bronze Saints to come to Sanctuary. Dohko's Mount Lu One Hundred Dragons Force collides with Shion's Stardust Revolution. Both are vanished. Later on, it would be Dohko who tells the Bronze Saints (except for Seiya and Ikki) before they entered Hell, that they had to acquire the Eighth Sense in order to advance in this realm without losing their lives.

Athough it had not mentioned, Dohko killed many Specters along the way from the entrance of Hell to the Wailing Wall and he was familiar with them since he had fought against them 243 years ago(see Lost Canvas and Next Dimension). His final appearance was along with his fellow Gold Saints to break the Wailing Wall, as only the combined powers of the Twelve Gold Saints can break the wall because the Gold Cloths were being bathed in the sunlight for a long time. He told the Bronze Saints that Hades' true body was hiding in the Elysion. Upon the gathering of the combined powers of the 12 Gold Saints, the Wall of Lament was destroyed and opened the gateway to Elysion Field, but doing so cost the lives of all of the Gold Saints.

Power and abilities
As a Gold Saint, Dohko has mastered the 7th sense, giving him great strength and the ability to move at the speed of light. He also achieved the 8th sense so he could go to the Tartarus.

Dohko has shown some telekinetic abilities as well as telepathy. Although he only showed a few techniques during the story, it is implied that he can use all the techniques that Dragon Shiryu can (except Excalibur), since he taught him those techniques. Even so, the only techniques he has officially performed to date are:
 * Rozan Hyakuryu Ha : Mount Lu One Hundred Dragons Force (廬山百龍覇, Rozanhyakuryūha): Dohko's ultimate attack. It takes the form of one hundred dragons.

Dohko's armor, the Gold Libra Cloth, contains 6 pairs of weapons to be used by the Gold Saints. Despite this, those weapons should not be used freely and it is up to the Libra Gold Saint to determine when they are needed. The weapons of Libra are 2 Swords, 2 Tonfas, 2 Lances, 2 Nunchuks, 2 Sansetsukons and 2 Shields. Each weapon is highly powerful, able to do things that even the combined power of several Gold Saints could not do..
 * Note: in the Anime-only Asgard arc, he was shown using the Shoryuha in a flashback to his youth. As the Asgard arc doesn't exist in Kurumada's manga, Dohko's appearance in it differs from Kurumada's official design.
 * Misopheta-menos: A gift from Athena herself. It slows down Dohko's metabolism in order to extend his life span for various generations.

Other media
In the Heaven Arc Prologue his soul is sealed with the other Gold Saints when they talk to the gods and say they always be loyal to Athena. Although being sealed he would encourage Phoenix Ikki and Andromeda Shun to fight against the angel of Artemis.

Dohko also appears in Saint Seiya Episode G, but to date he has not a prominent role. In the games for PS2 Dohko is an available character and he can use the same techniques of his pupil Shiryu.

Cloth, constellation and Temple
Dohko's guardian constellation is Libra, and his Gold Cloth represents it and its associated myth : The scales held by the goddess of justice Astraea. The temple he once guarded was known both in manga and the anime adaptation as Ten Bin Kyuu (天秤宮), the "Temple of the Scales."

As Masami Kurumada revealed in his sidestory prequel Saint Seiya Next Dimension, Dohko was originally a Bronze Saint and was awarded the Gold Saint status and the Libra constellation later. Thus, the original guardian constellation Dohko bore is yet to be revealed. He is also one of the main characters in the Saint Seiya: The Lost Canvas sidestory prequel. Since the two prequel exclude each other, which one is canon is unknown.

Unlike most of the Saints, none of the attacks he uses takes the form of his constellation, but instead take on the form of a dragon, similar to Shiryu. Even more unusual is that his symbolic creature, seen when his draws his full power, is neither the Libra nor a dragon, but a tiger.

Masami Kurumada used in his manga the Chinese concept of the duality of the tiger and dragon, in his characters Dohko and Shiryu. That's the reason for tiger and dragon images that appear on their backs when they burn their Cosmo.
