Red Guy

The Red Guy is the main villain of the Cartoon Network cartoon series Cow and Chicken - he is a demon heavily implied to be the Devil himself and has a very bizarre, illogical mind (even for a cartoon villain): he is often defeated by "Super-Cow" a superhero persona taken by Cow when The Red Guy's evil plans require foiling - in some ways this makes The Red Guy the archenemy of Cow herself though he is never much of a threat to her, always being beaten with ease by "Super-Cow".

The Red Guy has a habit of disguising himself as many different people ranging from cops to random people on the street - in all forms he enjoys causing mischief, mayhem and general nastiness: he is probably best described as a mean-natured trickster in terms of villaint - not seeming to want much in the way of conquest or ruin but rather taking a perverse joy out of being a general nuisance and bully.
