Kingdom Hearts II What would have happened...

If Roxas won in his fight against Sora? Would both of them have dissipated into darkness?

Would Roxas take over Sora's heart? Honestly, I've tried to think about an outcome but I really dont know one. Ideas?

 

It was a fight in Sora's heart... dunno maybe nothing, or maybe Roxas would've take physical form. Anyway Sora can't lose =( he is the main character bah.

 

Well, I think that maybe...Sora would've taken Roxas' place. They probably would've just switched places that way.
But I don't think Roxas would've like...Killed him or anything.​

 

I dont think anything would've happened unless Sora had let Roxas get to his heart.

 

you mean besides the fact that Sora is main character?

...

at best, Roxas would be more dominant. or prolly revert Sora's appearance into his Twilight Town costume.

 

There are two possibilities. Firstly, Roxas becomes the somebody and Sora becomes the nobody. He reappears in front of Donald and Goofy (remember, Sora vanished during the fight), fights through Castle Oblivion and destroys Kingdom Hearts.

The other option is that he breaks free of Sora and starts running about again. Sora, having already regained his memories from Roxas, continues to function normally (he may not be able to dual wield keyblades any more). Roxas is either knocked out and dragged back by Riku, or he helps take down Kingdom Hearts and Xemnas.
