I believe the worst thing that had a possibility of happening would be in the final Xemnas fight; if Riku just died during the part where Xemnas was quite literally beating the crap out of him.
Hello peeps, I'm a huge KH fan ((duh)), and I'm a newb here ((duh...again XD)). I've been a fan of Kingdom Hearts since roughly 04. I got 100 percent on Kingdom Hearts 1, then my friend deleted my file. Not a fun story =/. But I've joined here to keep track of all the latest news involving the infamous "Keyblade wars" and such. Of course, making new friends here wouldn't be bad, now would it? ;D
