am i the only one who remembers that MX's keyblade was a keyblade of people's hearts? thats the kind of keyblade riku obtained in kh1. now, who remembers what happened when sora stabbed himself with that? it created two nobodies: roxas and namine, whereas, when for instance sora defeats someone with his keyblade, he cannot destroy them, or really do any permanent damage at all. His keyblade is meant to destroy incomplete creatures, whereas MX's and Dark Riku's appear to be for destroying complete beings.
