HIM is a powerful, red-skinned demon and one of the series’ main antagonists. His gender is often something of confusion, as his voice, clothes, and mannerisms often contradict each other, but his name strongly suggests that he is male. He is also mentioned as being male multiple times, for example: “this king of darkness”, “sir” and “father”. It is implied that he is the devil himself, or at least some form of demon, in The Powerpuff Girls series, he is said to be “so sinister, so evil, so scary, so horribly vile that his real name can never be said, lest fear be struck into the very hearts of men.”
He is voiced by Tom Kane.
Him has a very androgynous appearance. He has large lobster-like claws, pointed ears, black widow’s peak hair, lime green eyes, a hooked nose and a long, curled beard. He has three long eyelashes on each eyelid, rosy pink cheeks and black lips, very often in a wide smile. A lady’s red jacket and skirt with pink tulle at the collar and hemline, a black leather belt with a bronze buckle, and black, thigh-high, spike-heeled boots complete his look.
He has been shown in numerous satanic forms as well. Most of which are revealed in apocalyptic, hellish situations or realms. These forms often enhance his power and cause him to grow an enormous size. When engaged in battle, he is an entity to be reckoned with; one example of his true form was witnessed in Speed Demon, when he became a giant muscular demon with red skin and black thigh, high spiked boots with a scale pattern and a pink garment made of fur.
