Ok so I know in both anime and manga they referred to his fruit as a paramecia type but I've been thinking they call him a rubber man, and he can't get hurt by most things and his whole body is rubber like other logia users. We have also seen another fruit ( the yami yami fruit) that even though its a logia type he can't fully turn into his element. Also what other power was luffy given expect just becoming rubber and in some way that could be his "element". Idk what do you guys think?
