Who are all the people who die in Kingdom Hearts?

Answer 1

Are you talking about the first one only? If so then don't read the rest, but I will tell you who dies in KH1, Re: Chain of Memories, 358/2 Days, and KH2. You are about to see so many spoilers if you are reading this sorry!

Kingdom Hearts 1- No one really you kill a lot of bosses + Maleficent, but in the second one Maleficent comes back to life and brings back the Disney bosses with her. And Ansem you think dies too.

Kingdom Hearts Re: Chain of Memories- Sora Mode- Vexen, Larxene, Axel ( who you think dies but doesn't he just teleports back to the Castle that never was.) and Marluxia. Reverse/ Rebirth Mode ( Riku)- Lexaeus, Zexion and Ansem.

Kingdom Hearts 358/2 Days- Alot of Heartless just like all the others. Mostly Heartless bosses( No Disney Bosses) , you get to fight Saix( he doesn't die yet), and Xion dies.

Kingdom Hearts 2- I'm not sure if any Disney bosses actually die or not. Okay there is the rest of Organization XIII so i will list them out. Demyx, Axel ( he basically kills himself if you play the game you'll see but he's not suicidal or anything.) , Luxord, Saix, Xigbar, Xaldin and Xemnas.

I don't have a PSP so I haven't played Birth by Sleep yet sorry!
