Aidan from Black Andromeda

He has short, light-colored hair, thin eyebrows, and black clothing, but with a dark color palette.

Aidan is the most sadistic and boastful of the Black Saints. He takes great pleasure in torturing his enemies with his blood-sucking chains.

After Ikki defeats his master Guilty, he enters the Black Saints' territory to reclaim his Phoenix Cloth. There, the Saint faces the Black Four, including Black Andromeda and Jango, leader of the Black Saints, and easily defeats them all. Later, the Black Four, having lost their leader to someone more powerful, offer their loyalty to Ikki and decide to help him in his revenge. At Ikki's call, Black Andromeda, along with her companions Black Pegasus and Black Dragon, set out in search of Black Swan, who was fighting with Hyōga of Cygnus. When they find them fighting, Aidan saves his companion from certain death at the hands of Hyōga by using his black chains to stop the Bronze Saint. After saving his life, Black Swan rejoins them and the four disappear to answer their leader's call. When they arrive in Ikki's presence, he entrusts them with guarding different parts of the Sagittarius Cloth that he had stolen. Aidan is in charge of saving the body part of the Cloth, and then they all promise to recover the missing pieces of the Gold Cloth. After this, Ikki sends a letter to the Bronze Saints challenging them to come and fight on Mount Fuji, and they all must carry a piece of the Gold Cloth. The winner of the fight would obtain all the parts of the Cloth. On Mount Fuji, while the Bronze Saint Shun of Andromeda was trying to rescue his teammate Pegasus Seiya from the abyss into which he had fallen due to the pain inflicted by Black Pegasus's Black Meteors, Aidan attacks the Saint of Andromeda with his black chains, while asking him why he is so stubborn in rescuing someone who is a dead man, in order to make him forget the idea of ​​​​rescuing his partner and finally fight him face to face.

After repeatedly trying to get the Saint of Andromeda to abandon his companion, Black Dragon appears, who tells Aidan to stop torturing Shun, since he is the younger brother of his leader, and he should finish him off once and for all, so Aidan proceeds to attack the Bronze Saint with his Black Fang Nebula, absorbing the Saint's life. While Shun was being affected by the Black Fang Nebula, the Saint of Pegasus cuts Andromeda's chains, falling into the abyss. The Saint of Andromeda begins to cry, and in a fit of rage, breaks Aidan's black chains and then uses his Nebula Chain, ending Aidan's life. Once all the fighting is over, an earthquake is caused by Misty of Lizard on Mount Fuji, so Mu teleports the Bronze Saints but also the corpses of the Black Four since he considered that it would have been regrettable to let them die like that. He then uses the corpses to trick the Silver Saints into believing that the Bronze Saints had died when in fact it was not them but their counterparts.

•Black Fang Nebula: This technique involves transforming the Black Chains into a multitude of bloodthirsty snakes that completely surround and trap the enemy, slowly sucking their blood. When the chain is broken, the snakes disappear, returning the chain to its original form.
•Black Rolling Defense: This is a simple but effective defensive technique, using the black circular end protection chain on the left arm, the saint creates this special movement during combat.
•Ankoku Storm: is a technique that consists of generating a swirling air current, which turns into a violent storm that destroys the opponent.
