This character is almost never one of the main cast. Exceptions to that rule include Mimi, Drew's nemesis from ''Series/TheDrewCareyShow'', who is the second main character of the series; and Marcy from ''Series/MarriedWithChildren'', who started out as just an ultra-nice neighbour but wound up as Al's cackling nemesis. An all-purpose {{jerkass}} along the lines of Frank Burns from ''Series/{{Mash}}'' doesn't count, since he's hated by everyone equally.
