Strong Sad from Homestar Runner, whose two brothers Strong Mad and Strong Bad enjoy heaping physical and psychological abuse on him.
Also from Homestar Runner, almost everyone in Strong Bad's comic book Teen Girl Squad.
Nebulon, Rumble Red, the King of Town, Cartoon Mary Palaroncini, Coach Z, and 1-Up are also frequently abused. There's only one person who does like Nebulon's style... and she's an enormous alien cow. However, it's justified in Red, Mary's and 1-Up's cases, in that they're parodies of annoying cartoon sidekicks.
Homestar Runner himself can also qualify, considering how many times Strong Bad has insulted, assaulted and tricked Homestar for the sake of his own enjoyment. That and Marzipan keeps breaking up with him. Bubs also squeezes Homestar for all the money he can get, but Bubs does that to EVERYBODY.

She recently shaved her hair and gained more weight as a desperate attempt to get men to stop hitting on her. It doesn't.
Red vs. Blue. Pretty much all the characters get their turn, but Grif probably qualifies the most, getting yelled at, insulted, threatened, beat up and even shot on occasion, all because he didn't want to risk his life in a war. Oh and because he's snarky.
Washington sort of strays into the territory when you consider his speech at the end of Recreation, leading to a possible case of The Dog Bites Back:
Chairman: Agent Washington, when you find these blue soldiers that you're talking about, what makes you think that they are just going to give you the Epsilon unit when you ask for it?Washington: Heh heh. For as long as I can remember, I've been lied to, taken advantage of, shot in the back and left for dead. And now, I have a way out of all of this. What in the hell makes you think that I'm going to ask for it?
The title character in the Charlie the Unicorn videos. The blue and pink unicorns apparently come up with extremely convoluted and surreal plans just to make Charlie miserable. This is pro
