It relies on the level mostly which decides the players abillities.
I almost defeated Firesword in Distopia but I lost coz i wasn't trying in the beginning (I'm not saying i WOULD win, I say there might have been a chance).
Firesword beat Dizzy once in BBlair, would that make him better than dizzy?
I beat Unhit once in Distopia (I was crying of joyness) but that doesn't make me better coz I still like to eat suxes in other levels like BBlair. So it relies on the levels as well.
