Zombie Man

Zombieman is an S-Class, Rank 8 Hero in the Hero Association in One Punch Man, known for his immortality and extreme regeneration rather than brute strength, allowing him to wear down powerful enemies like Dragon-level monsters, though his direct physical strength is less than that of other S-Class Heroes. His power lies in his ability to withstand almost any damage and his intelligence as a detective, making him an unstoppable attrition fighter, although his regeneration consumes energy.
