Satan

Satan has a pinkish-red skin, yellow eyes and teeth, big horns, a tail, wings and a black crown. He is also an overweight with a big butt. His legs are black and bent backwards, resembling those of goat.

Satan is quite plump as a demon. He is magenta in skin tone, while he has conjoined black eyeballs with yellow pupils, black horns, small wings, and a stubby tail. His outfit consists of a floating crown atop of his head and black bottoms.

Satan first appears in a cutscene, where he asks his red magical mirror, who is the most reddest guy than Satan himself. In which mirror reveals Dynamite Anton as the reddest individual. Enraged and envious, Satan sends his huge army of Ballbusters to steal all of Anton's spirit collection.

Satan is a leader who desires to be known as the most reddest being ever to exist, and grows envious of Anton after find out about his more crimson skin than his, retaliating against the destruction worker by stealing his entire collection of spirits. Being wrathful as he is, he knowingly strategizes this plan with stealing Anton's spirits to lure him over to him and confront him physically.

Another of Satan's notable traits is his excessive extravaganza and bombastic personality, as since he talks snobbish to the magic mirror to shine the most red, and soon screams in complete ham upon the realization about Anton instead being the reddest of them all.

Giga Satan is a special transformation seen in Antonblast. It is a powerful form of Satan that was achieved by harnessing the power of Anton's red skin pigmentation, who serves as the true final boss of the game. Giga Satan was ultimately defeated by Anton, who had undergone the all-powerful transformation into Oni Anton using the power of his Spirits.

Giga Satan appears relatively similar to his base form, with the main takeaway being Satan having finally obtained the red skin pigmentation from Anton that he had always thirsted. Satan is also considerably less obese in his Giga form, now becoming extremely muscular whilst still maintaining a prominently exaggerated posterior. During the last three phases of his boss fight, Giga Satan is suddenly changed to be extremely gigantic in size, towering over Oni Anton as the size of a skyscraper and being able to hold him in the palm of his hands.
