Luffy~

I have had a thought, which stemmed from a One Piece conversation. I don't know if this is known, or not, but a friend mentioned to me that Blackbeard's Darkness fruit powers contribute to his eagerness to swallow more 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 Fruit powers must allow him to absorb these Devils, to the point where he has already swallowed two and could potentially swallow more. I find this incredibly intriguing. If anyone has any thoughts, then please share, as I will be only to happen to listen.
