Kingdom Hearts II From now on...

Ok, so.. I've been wondering, what are the three island-keybladers able to do now?? I mean, how will Sora & Roxas co-exist, or Kairi & Namine'? Does Sora have any new abilities now that he's 100% completely combined with Roxas now? What about Kairi? She just reunited with her Nobody at the end of the game, so has she gained any new powers maybe? Can she continue to wield that Keyblade that Riku gave to her? And what of Riku? The darkness between the 3 seems to not be dangerous anymore... Sora has his Anti-Form to keep his darkness in check, Kairi is a princess of heart, and Riku has pretty much exhausted his powers of darkness throughout the games... He can't even open Corridors of Darkness anymore, but for whatever reason, he can still use Dark Firaga and Dark Shield...

 

Riku probably can use those, cuz they won't affect him by draining dark powers from him...

 

How so? They still stem from the darkness... He was unable to use any of them until he acquired his Dark Riku form in Hollow Bastion...

 

Yeah, but don't forget that darkness lingers in every heart, and Riku's body was taken over by Ansem, so that might help him use those powers.. Besides those don't seem to drain much darkness from him..
