A man in his early 180s cm with deep black hair and gray eyes. When caught in the light, his eyes shimmer with a faint golden hue. With pale skin and a lean, muscular build, he gives off a sharp and cold impression overall. He maintains a calm expression with almost no emotional fluctuations, never losing his composure even in the heat of battle. The faint smiles he occasionally wears only add to his sense of intimidation. Faint shadows hang under his eyes, and when he uses his powers, black crack-like patterns spread across his hands or neck. His shadow feels unusually dark and alien. He prefers neat, black clothing with minimal ornamentation. He is quiet overall, but exudes an increasingly dangerous aura the closer one gets to him. An ability user who manipulates darkness and the void, he brands targets with the 'Mark of Apocalypse.' The marks accumulate with every strike, and the damage increases exponentially over time. Since the marks do not fade easily, he gains an overwhelming advantage as the battle drags on. He can use 'Void Distortion' to warp space and redirect the trajectory of attacks, and his combat style involves assimilating into shadows for movement or surprise attacks. His ultimate move, 'Apocalypse Harvest,' detonates all accumulated marks at once, collapsing the surroundings and finishing the target, with power maximized proportional to the number of marks. His villain alias is Eclipse.
