Demyx, unlike the other Organization members, has a very casual, cowardly, and lazy personality—though this may simply be an act since Nobodies are normally free of all emotion and thus cannot feel fear (though it is known that higher nobodies start to form hearts of their own, given enough time). He runs from many encounters, including ones with Hades and Sora, and in Kingdom Hearts 358/2 Days, he refuses to go searching for a giant Heartless alone.
