Kenuma of Black Pegasus

Black Pegasus has light hair and eyes. He is similar in physique to his counterpart, Seiya, and wears black clothes. His hair is swept back and he has a thin face. Kenuma is presented as Seiya's identical double, being physically identical to the Bronze Saint but with a dark color scheme. He has jet-black hair and eyes. The clothing he wears under his Cloth is completely black.

He seems to be as impetuous as Seiya. He's also proud of being a Black Saint and very confident in his strength.

After Ikki manages to defeat his master Guilty, he enters the Black Saints' territory to reclaim his Phoenix Cloth. There, the Saint faces the Black Four, including Black Pegasus, and Jango, leader of the Black Saints, whom he easily defeats. After losing their leader, the Black Four offer their loyalty to Ikki and decide to help him in his revenge. At Ikki's request, Black Pegasus and his companions go out to search for Black Swan, who was facing Hyoga of Swan. After finding him, the group retreats.
When they arrive before Ikki, he entrusts them with guarding different parts of the Sagittarius Cloth that he had stolen. Black Pegasus is in charge of guarding the waist part of the Cloth, promising to recover the missing pieces of the Gold Cloth. After this, Ikki sends a letter to the Bronze Saints where he challenges them to present themselves to fight at Mount Fuji*, and each of them must carry a part of the Gold Cloth. The winner of the fight would obtain all the parts of the Cloth. On Mount Fuji, Black Pegasus awaits the Bronze Saints inside a cave. When Pegasus Seiya enters, he appears before the Saint and attacks him with the Black Ryūsei Ken. The Black Saint says that he did not expect to beat so easily someone who was trained in the Sanctuary, but then realizes that Seiya is standing behind him, to his surprise.
Black Pegasus asks him how he managed to dodge all of his attacks, to which Seiya replies that at least five or six of his meteors hit him but that he was able to resist them thanks to the fact that his new Cloth is now more resistant. Seiya attacks with his Pegasus Ryūsei Ken and defeats the Black Saint, who drops the part of the Sagittarius Cloth he was guarding, which is picked up by Seiya.

As Seiya prepares to leave, Black Pegasus tells him that despite having defeated him, he will not be able to reach Ikki, as he has been hit by one of his Black Meteors and will soon suffer the "Terror of the Black Death". Once all the battles are over, an earthquake is caused by Misty of Lizard on Mount Fuji, so Mū teleports the Bronze Saints and the Black Four. He then uses the corpses to trick the Silver Saints, making them believe that the Bronze Saints had died when in reality it was not them but their counterparts.
