Cancer Death Mask is one of the Gold Saints in Saint Seiya, serving as the guardian of the Cancer Temple in the Sanctuary. He is a cruel and sadistic warrior who takes pride in killing his enemies and collecting their faces as trophies. Aligned with the darker side of the Sanctuary’s power structure, he acts as an antagonist to the Bronze Saints during their climb through the Twelve Temples. His character represents corruption, brutality, and the misuse of sacred power.
