I understand the cartoon, but to me it's all but recognizable. I don't "main" a character in a fighter game. Granted, I rarely play fighters to begin with, but even so I understand that they somewhat rely on a more complicated version of "rock-paper-scissors". Characters aren't necessarily strong (or OP) by themselves, but unless you're playing a game not worth playing, they are strong against a certain character (fast versus slow, ranged versus close range...attributes like that).
So in the end, rather than specializing, I goof off with most or all of the fighters. I often have no time to even come up with the idea that one is considered overpowered, as I've already played (and lost) with it.
Erm...I hope it doesn't come off as condescending (if so, I'm sorry), but perhaps you should try switching characters more often. I'm not sure what the mindset is among players, but I honestly don't believe that the creators attempted to put one (or more) characters in their games for the purpose of having people not using them.
