It’s no secret that the Blackbeard Pirates are on a mission to gather devil fruits, thus why Burgess was even on Dressrosa in the first place – in order to gain the Mera Mera no Mi.
Blackbeard himself has shown knowledge of how to steal a devil fruit when he did the unthinkable and murdered a nakama when serving under Whitebeard all those years ago.
Let’s see who are the devil fruit users in the Blackbeard Pirates crew and especially which devil fruits could already own or obtain the other members.
CONFIRMED DEVIL FRUIT USERS:
#1-Marshall D. Teach “Blackbeard” has become the first and, so far, only user to wield the powers of two Devil Fruits at the same time. With the power of darkness (Yami Yami no Mi), which “reduces anything to nothingness”, and the power of quakes (Gura Gura no Mi), which “brings destruction to everything”, Blackbeard claims himself to be truly invincible and the strongest of them all.
Since Blackbeard has both the most powerful Paramecia devil fruit and the most powerful Logia devil fruit, many speculated thet he will get a third Devil Fruit, which should be a Zoan-type devil fruit. Most people agree that the most powerful Zoan type fruit at this moment is Kaido’s Uo Uo no Mi, Model: Seiryu or Marco’s Tori Tori no Mi, Model: Phoenix.
#2-Shiryu of the Rain has the powers of the Suke Suke no Mi, a Paramecia-class Devil Fruit allowing him to turn himself and whatever he is holding invisible.
