Is that even a serious question?
Because I'm the only Batman to win tournaments (and yes, KiT I used Batman and nobody else), I'm the only Batman to place top 8 around fifteen times, I'm the only Batman to do alot of things. I'm the only Batman to ever beat certain people that other Batman players can't, for example I'm the only Batman to ever beat WoundCowboy/Playing2win, I'm the only Batman who ever beat M2Dave, I'm the only Batman who ever beat Noobe/Whiteboi, I'm the only Batman that beat Jupiter in a major, I'm the only Batman who is undefeated in the mirror, I'm the only Batman who has took more than 20 games off Theo in a set, I'm the only Batman who has beaten Max/Biohazard, I'm the only Batman who has beaten 16bit, I'm the only Batman who has beaten Saltface, I'm the only Batman who has beaten Deg, I'm the only Batman who has defeated Blind Ducky, I'm the only Batman who has beaten Chris G, I'm the only Batman who has beaten Emperor Murk, I'm the only Batman who has beaten A foxy grampa/filipinoman.
My Batman has done many things that other Batmen have tried and failed. My Batman has proven itself tournament after tournament again over and over and over. Just because I like using alot of characters and get bored using the same character for a long period of time, doesn't take away from all the accomplishments one of my characters has. I don't understand your logic. If there is a better Batman then mine, then who is it? And why?
