|First Appearance||No Smoking|
The Red Guy serves as Cow and Chicken's rather incompetent arch-nemesis throughout the series. Originally portrayed as the Devil in the pilot (where he attempted to lure Chicken down to Hell by getting him to smoke cigarettes), he spends his time trying to either scam, torment, physically harm, or (in the earliest episodes) kill Cow and Chicken. He often disguises himself as an authority figure (principals, kings, lunch ladies, police officers, etc.). In some episodes, multiple and seemingly distinct Red Guys are present, usually working together. His catch phrases are, "Hello, it's me, the Red Guy" , "Sue me", "Ooh", "Fetching", "Ahh", "Oh", and "Is that a crime?" (Pronounced "cra-yim", like his "nine" is pronounced "na-yin"). Like the other characters in the show, Red will refer to everyone else as ladies, girls, gals, or men regardless of their actual gender.
A running joke throughout the series deals with the fact that the Red Guy does not wear pants (or underwear) and seems to take pride in his buttocks and his nudity. He often introduces himself with fake names exaggerating this fact (i.e. Dr. Laxslax, Ben Panced, Dr. Bottoms, Seymour Butts, Mr. Lackapants, Lance Sackless. Mrs. Bare Derierre, Officer Pantsoffski, Officer O'Fannyhee, Rear Admiral Floyd, Ivan Panced, Dr. I.C. High-knee, Mr. Breezybum, etc.).
Strangely, despite the long history of animosity between them, Cow, Chicken, and the Red Guy are actually portrayed as friends in some of the episodes. Because there have been multiple Red Guys in some episodes, it is unknown whether the Red Guy that always tries to make life difficult for Cow and Chicken is the same Red Guy that befriends them, or if it is a different one each time.
