hey do you guys think that meliodas has possessed someone like how fraudrin did with dreyfus? i mean, just look at fraudrins original appearance and compare it to his shadow and the rumor said about him, even when he activates his demon mark his eye colour changes like dreyfus' eyes, maybe after he comes out of his cocoon of darkness we'll see his original appearance
EDIT: hell maybe even all the demons are like that, maybe well have to wait and see
