Muzan is a major antagonist in the original Devilman anime. He serves as the second of the three mighty Demon Generals under the demon lord Zennon. In appearance, Muzan is a towering bipedal demon with feline features, covered in pink fur and sporting several tails that spread across the lower part of his body. He has a spiked white mane, drooped yellow eyes, and a pair of long blue antenna. His role in the story is primarily that of a strategist; he spends most of his time observing events from a distance and commanding his demon soldiers through various schemes rather than engaging in direct combat. When he is finally called to battle, he proves to be a deadly threat. His personality is defined by patience, cunning, and a tactical mind, making him a dangerous opponent who prefers to manipulate situations rather than act impulsively. His motivations align with the Demon Tribe's goal of conquering the human world and defeating Devilman. He takes over after the failure of the first general, Zannin, and intensifies the assault. In terms of key relationships, Muzan answers directly to Zennon and serves as a field commander, with Devilman as his primary adversary. His development is limited, but he eventually abandons his indirect approach and personally attacks Nakado Academy, holding its students captive in an alternate dimension in a final attempt to eliminate Devilman. Notable abilities include his strategic acumen, the capacity to command lesser demons, and his powerful physical form, which he employs in direct confrontation. He remains a formidable and calculating force within the demon hierarchy until his defeat.
