after beating this amazing game, i found out about re-fighting the bosses and they have a ton better stats and such. however, is it possible to re-fight the 5 final bosses with riku and the 1 with sora? they would be a lot of fun with maxed out stats and such.

To get the Secret Ending if you beat the game already you have to re-fight the final bosses and do all that other stuff, so yes you can re-fight them just like in any KH game. Where are you leveling?

Of course you can, just go to where you're supposed to fight them. Even after you beat the game, it basically gets stuck to pre-final boss fight, so you can re-do it as many times as you want.

are you sure? i go to the place where you fight red eye but nothing happens. nor can i find a secret portal to re-fight him. i can only fight young xaenort (spell fail) and the ventus...armor...thing. and they dont have buffed stats.

 

my question was can i re-fight all of them and THEY have buffed stats.

I don't think you can re-fight the final bosses with improved stats.

There are no buffed final boss fights. Once you beat, you can only refight the finals (xemnas and xehanort) normally as in every game.
