you make a good point about Wheeler and his redeeming qualities, but I just feel that they could have done a bit better with writing when it came to his character sometimes.Ok, I feel the need to defend Wheeler. Yes he was generally lazy/apathetic most of the time, and the only reason he seemed to stay was to try to score with Linka. In spite of all that, I think he really proved himself enough to deserve to be on the team. IIRC He even saved a kid from being beaten up right before he got his ring. Plus his power was fire and that was the best one of them all (at least better then Ma-Ti's Heart which was useless except when they needed a convenient plot device). Besides every character on that show was a stereotype (I'm surprised there wasn't a defamation lawsuit filed by every ethnic group in the world). This isn't to say you can't be annoyed by him for whatever reason or no reason at all, but I just felt like I had to defend him.

Live Action:
Flava Flav: from... Flava Flav LOL, I know this guy isn't really a character but an actual person who happens to have his own TV show, but man I can't stand him. He is such a grimy sweaty looking ugly old guy who looks like a drug addict you would find stumbling around in an alley. If it weren't for the fact that he was rich, no girl would touch his nasty self with a ten and a half foot pole with a condom on it. i don't want to think of how many girls he's been with through out the season. Makes me want to puke just thinking about it.
Winnie Cooper: from the Wonder Years. God I wanted to just slap the shit out of this girl. This girl was the epitome of emo! Nothing Kevin ever said was the right thing and she always got offended and hurt by everything, half the time I thought she just acted that way to get Kevin to chase after her more, manipulative bitch she knew what she was doing. Man I so wanted Kevin to stop chasing after her, she wasn't worth the aggravation. And what got me was even when they did hook up Winnie always ended up cheating on Kevin and acted like he was a jerk for getting angry at her and acted like what she did with other boys was none of his business--even when they where going out.

Kimmy Gibler: from Full house. She was just annoying
Budd: from Married with Children. he was funny for the most part but they made his character pathetic at times that i couldn't really find him to funny unless he was with Kelly. Thankfully he got better as the series went on and he got older.
Crystal : from Roseanne. She was sooo emo and and she ever seemed able to do was bitch and moan about how miserable her life was and was constantly having a melt down that Roseanne or Jackie had to help her deal with. She was just weak ling as an adult and she always made it seem like she would shack up with Dan given the chance, but since she could have him she married his Dad. And then she bitched and moaned about how he wasn't around even though she was told he was a hands off kind of husband. I was so glad they drop her character from the show as the series went on.
