But I don't know what to say about his eye, it reminds me of Guts' eye from Berserk, since Oda has something with the left side its the left eye, it might be the results of his training(I mean an accident happened and he lost his left eye), but it might be something else, the eye of the demon or something, his haoshoku haki, only Oda can tell us what it is:)))
