The Devil: Him versus Red Guy

HIM
Him is a mysterious, supernatural, red-skinned, effeminate, immortal, devilish entity. His physical appearance is an amalgamation of sorts with crab-like claws, red skin, pointed ears, a hooked nose, yellow/green eyes and a long, curled beard, wearing makeup, a woman's red jacket and skirt with pink tulle at the collar and hemline, and black, thigh-high, spike-heeled hooker boots. His voice ranges from a high-pitched falsetto to a deep, booming basso profondo.According to the narrator in Him's first appearance, he is "so evil, so sinister, so horribly vile, that even the utterance of his name strikes fear into the hearts of men." He is shown to feed off the negative emotions of human beings and become powerless when there is little or no negativity in the air.
 
RED GUY
The Red Guy is a red creature of an unknown species resembling a demon, and in the pilot "No Smoking" episode he was shown as Satan. In later cartoons, he is no longer shown as that character, but instead as a being who is known for masquerading as different people with different occupations in order to harm, torture or scam Cow and Chicken for reasons never established in the series. Often, these characters are given pun names related to the Red Guy's bare posterior and lack of pants, and sometimes he has been known to disguise himself as more than one character in the same episode in order to continue bothering Cow and Chicken, and sometimes I.R. Baboon and Weasel.
