Libra Genbu

Libra Genbu (天秤座（ライブラ）の玄武 Raibura no Genbu) The Libra Gold Saint in the era of Omega, governing the Balance and the Harmony. He can use the element of water.

Background
Genbu is revealed to be Libra Dōko's final apprentice, taken under Dōko's care as a child between the years of Libra Shiryu's completion of training and Dōko's death in The Hades Arc. Genbu was a late bloomer in terms of controlling his cosmos and the martial arts training, therefore Genbu showed a more lack of interest in Sainthood compared to  Shiryu. Yet Libra Dōko knows his potential as a successful Saint and hasn't gave up on Genbu, therefore Dōko continues to enlighten Genbu with the cosmos training, the Lushan Martial Arts skills, the words of wisdom, and have Genbu inherit his ideal of righteousness. But due to the lack of confidence, Genbu eventually left Dōko's training and the path of Sainthood all together and lived a low-profile normal human life, for which Libra Shiryu distastes. Until the breakout of the war between the Martians and Athena's Saints affecting the life and death of the Earth that made Genbu recollecting Libra Dōko's words, remembering it shall be his duty to rise up as a Saint when it's deemed absolutely necessary. Now powerful, confident and determinded, judging the majority of the Golden Cloths and Saints are affiliated with the Martians, along with Libra Shiryu's inability to serve as a Gold Saint, Genbu privately set out the search for the Libra Cloth to inherit before the enemies obtain it. It's is found that Libra Shiryu has been hiding it, but with the scar between them, it is impossible for Genbu to locate and inherit the Cloth unless Shiryu voluntarily releases it. And it was not until Shiryu's son, Dragon Ryuhou needed the Libra Cloth to reach for the water element generator that Genbu was able to find it. When the Libra Cloth showed up, it turns out the Cloth indeed agrees with Genbu's values and his preparedness to be a Gold Saint and therefore let Genbu inherit it. In order to go undercover as a Martian-affiliated Gold Saint, Genbu reserved his true intentions from the Bronze Saints, leaving the impression that he was a powerful Saint who stole the Golden Cloth.

Obtaining the Libra Cloth
Genbu first appears on the outskirts of the Lushan waterfall shortly after Aria and Dragon Ryūhō destroy the water element generator and had a brief exchange with the young Saints (Aquila Yuna, Wolf Haruto, Pegasus Kōga, Dragon Ryūhō and Aria), where he intended to suppress them and retrieve the Libra Gold Cloth, at that moment Dragon Shiryu had released for the young saints' mission. However, upon feeling the cosmos of Dragon Shiryu, he took the option to retreat, but not without taking with him the Gold Cloth. The Bronze Saints considered this as theft; but the Cloth Stone voluntarily came to his hand. Genbu then says that the armor has chosen him as its rightful owner and leaves. He was a Saint filled with mysteries, and was a potential suspect who might be serving Mars. His Cosmos during that encounter had an overwhelming aura and apparently has a dark, blueish energy that radiates.

Versus Aquarius Tokisada


Before Aquarius Tokisada can do anything more to the young bronze saints, Libra Genbu teleported all of them to his Libra Temple and directly challenges Tokidasa. Genbu holds nothing back as Tokidasa prepares to slow down time. Even so, Genbu is still too fast for the Aquarius Saint and Tokidasa is punched. The bronze saints watch in awe as the gold saints raise their cosmos and fought so fast as if they were appearing and dissapearing. Tokidasa fought and fought but is still no match for the Libra saint. Tokidasa then proceeds to use his ultimate attack, the Chrono Execution. As Libra vanishes into the blast ,Tokidasa thought that he was triumph and aimed for the bronze saints. Suddenly, Genbu appeared from the blast and use his greatest move. It was revealed that Libra Genbu was the final apprentice to Libra Dōko, who was also Libra Shiryu's master, and that he has sworn loyalty to the true Athena, and is upholding to the final commands of Libra Dōko to inherit the the Libra Golden Cloth of Balance and Harmony from the now disabled Libra Shiryu. Genbu also noted that his relationship with Libra Shiryu has been estranged, since Genbu did not continue with the path of Sainthood for a long period of time prior to him obtaining the Libra Cloth. When Tokidasa was finally beaten, Libra Genbu provided the bronze saints the location of Athena, which he obtained from undercover and bids the bronze saints to move on as fast as they can. Medea, watching all of the actions from her crystals, took note of Libra Genbu's loyalty towards Athena and starts to break the Twelve Temples down, forcing Genbu to occupy all of his Cosmos to maintain the stability of the Temples and unable to aid the bronze saints further down the road.

Weapons
Libra Weapons: These are  12 golden weapons enclosed into  Libra Gold Cloth, and they are composed by 6 pairs of Swords, Tridents, Nunchaku, Tonfars, Triple Rods and Shields. The Libra Saint is voted to protect and carry the 12 weapons, each of which is for each one of the Gold Saints, whose power is said could destroy a star. Athena, who hates the battle and the use of weapons, forbade his Saints to use the Libra Sword these, with one exception: if the Libra Gold Saint considers necessary to use weapons, for example in order to face an extreme situation (as the Wailing Wall or the Oceanic Pillars) then the Saints can use them. For his difficult role, the Libra Saint is often considered the holder of the balance of power in fight between good and evil. On Omega the Libra weapon can teleport the Saints.

 * Rozan Shō Ten Ha (廬山昇天覇) : Doing the same movements that Shiryu and Ryuhou, Genbu frees his hands a gigantic blast of energy at the enemy.

Abilities
Genbu has a powerful and overwhelming Cosmo, as he was capable of threatening the life of the Bronze Saints, while in his mission to retrieve the Libra Cloth. His cosmo is so powerfull that he managed to prevent the destruction of the Twelve Houses. Genbu has also shown that he can move faster than the speed of light by elevating his cosmo, this technique was used to defeate Aquarius Tokisada's technique by compensating the velocity. Genbu also has the ability to teleport people using the weapons of the Libra Cloth. Genbu has control over the Water Element.

Cloth
Genbu wears the new Libra Gold Cloth, previously worn by Shiryu. This version is no longer stored in the famous Pandora boxes, but in crystals called Cloth Stones.

The Cloth has a similar structure compared to its original version, but has a more simplified format. The shells are now engaged in both right shoulder which now is prolonged to the forearm.

Constellation
Libra (the scales, symbol Unicode ♎) is the seventh zodiac constellation in the sky.Pretty quiet, no first magnitude stars, lying between Virgo and Scorpio west east, notably more striking. As evidenced by the names of its brightest stars, was once part of the pincers of the scorpion: well, Zubenelgenubi (α Librae) means "southern claw" and Zubeneschamali (β Librae) "northern claw". Α and β are visually studs equilibrium in the balance, while γ and σ are the cymbals.

Trivia

 * On Saint Omega Ultimate Cosmo, Genbu can use the Libra weapons, but on the anime the Libra weapons were not used.
 * Before chapter 39, there was a speculation of a possible relation of Genbu being a descendant of Dohko because Genbu resembles his master Dohko, but the anime never stated that.
 * Genbu is a mythological Chinese animal half-turtle half-snake suggesting a duality of equilibrium as the sign of Libra represents, same as the balance that Dohko and Shiryu represented as tiger and dragon.
