Zombieman

Zombieman is the S-Class Rank 6 professional hero of the Hero Association and a product of the House of Evolution, gifted with regenerative abilities that make him functionally immortal.

Visibly bothered by the uncooperative attitudes at Hero Association meetings, Zombieman is nihilistic and notably sensitive to human death, a disposition likely shaped by his own countless deaths and years of experimentation at the House of Evolution. He prefers operating independently, dislikes gatherings, and rarely discusses his past, yet still maintains real respect for common courtesy. Despite his grim outlook, he's surprisingly forgiving, letting go of grudges that serve no purpose, and shows genuine fondness for children — including his camaraderie with Child Emperor. His sharp, almost detective-like reasoning lets him recognize an unwinnable fight before it costs him everything.
