I have had a thought, which stemmed from a One Piece conversation. I don't know if this is known, o not, but a friend mentioned to me that Blackbeard's Darkness frutta powers contribute to his eagerness to ingoiare, inghiottire più than one Devil's Fruit, which, as it is widely known, is impossible for other Fruit-users, as the Devils inside the fruits will fight and the user will be destroyed in the aftermath. However, I am thinking that Blackbeard's Devil's frutta powers must allow him to absorb these Devils, to the point where he has already swallowed two and could potentially ingoiare, inghiottire more. I find this incredibly intriguing. If anyone has any thoughts, then please share, as I will be only to happen to listen.
