He shot the keyblade through the middle section of him at the end of Kingdom hearts 2, but you never saw the direct blast, so there's no way to tell if it severed the spine. however, as irrelevant as it seems, Riku may have had his back broken during the fight by xemnas. you might be confusing Riku's dire blow with Xemnas' death.
When you fight Xemnas Sora will get captured at some point and Xemnas will drain his HP. You'll have to be Riku to save him.
i think that sora would beat any body's butt in anything that he did (maybe even riku) and i think xemnas and Darth Vader wouldn't even fight cuz it would be all like... Darth"xemnas i.. am... your father..." xemnas" NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO..... but you... you killed my mother.." Darth.."ummm.. no that was my twin brother"xemnas"o.. DADDYY!!!!"
when sora gets trapped by final xemnas you have to use riku to free him, that copy that xemnas does is quite frustrating you need to attack him or he will push you back to the start and you will not be able to save sora,when you get close to the real xemnas a RC(reaction command) will appear on the command box JUST PRESS IT and done
Its kinda complicated but most would say in Kingdom Hearts 2 after you beat 1000 Heartsless and you see Xemnas in the dark depths when Sora demands to know if he knows where Kairi is. But it turns out that in Kingdom Hearts Final Mix you fight Xemnas in the place in where you fought Dragon Maleficent in Hollow Bastion plus Xemnas kinda talks about Sora being incomplete to him. In other word he telling him about Roxas without saying his name.
He is Xemnas, who had battled Sora to gauge his strength.
Kingdom Hearts most likely receded back from whence it came; scattered through the hearts that summoned it.
If Xemnas continued existing, he'd release Kingdom Hearts, and everyone would disappear because a heart can't be shared.
No, not at all. Sora is the only playable character. In the final battle, however, you get to play as Riku when Xemnas's HP bar gets down to halfway gone, in order to save Sora. But after that, it's back to playing Sora again.
No. Terra and Ventus' hearts are both inside of Sora.
You can not phisically use Riku's "Way to the Dawn", but in the final battle with Xemnas Riku lends Sora his keyblade to finish Xemnas off.
Unfortuantely, no. But you can use it while playing as Riku while trying to save Sora from Xemnas's clutches in the last battle of the game. At the end of the game after Sora and Riku deflect the fire beams, Riku will be attacked and Xemnas will try to kill Sora, but Riku pushes Sora out of the way and gets hit instead and as he's flying he calls for Sora to grab his keyblade, and Sora will jump and grab Riku's keyblade and use it to perform one of Sora's best finishing moves, Omnislash.
You can only play him once, and that's when you and Riku are fighting Xemnas for the last time. Sora get's captured by Xemnas and you have to use Riku to save him
