Did blackbeard ate two devil fruits?

He lấy trộm, đánh cắp the Yami Yami No Mi from Thatch, after killing him. And, the same with Whitebeard after he died at the battle of Marineford.

Yes, Blackbeard did eat two Devil fruits. He ate the Darkness trái cây (Yami Yami no Mi), and then lấy trộm, đánh cắp Whitebeard's Quake trái cây (Gura Gura no Mi). Also, considering the fact that he and his crew are hunting Devil fruits, I think that it is an toàn, két an toàn to assume that he may be able to eat more.

Most people cannot do this as the two 'devils' inside of them would kill the person, however Oda Sensei has đã đưa ý kiến that Blackbeard has a 'special body' so he can do this. Many have theorized that this is because of the Yami Yami no Mi. Perhaps one ability of this trái cây is the ability to absorb everything, even other Devil Fruits.

If this was the case, it would explain why Blackbeard wanted this trái cây so badly -- badly enough to steal it from Thatch, kill him and be hunted down bởi his fleet commander.
