This is a very old theory. Almost everyone I know who is a fan of One Piece believes in the Blackbeard Cerberus theory to some extent. At the very least it's agree that Blackbeard will get 3 devil fruits, the strongest of each type: Parameica(Quake), Logia(Darkness), and Zoan(???, most likely whatever Kaido has).
