Blackbeard is now considered one of the strongest characters in the series so far, but despite having two powerful Devil Fruits, there are some characters who can match him and beat him.
Shanks is one of the most fearless and most powerful characters. He’s fought with Whitebeard and Kaido, and he also protected Coby by holding off Admiral Akainu with one arm. Shanks and Blackbeard have also fought before. The result is unknown, but Shanks did get a scar on his left eye.
The Darkness fruit’s oppressive powers wouldn’t work on Shanks, as he has no Devil Fruit. Also, Shanks can use all three of the Hakis. I think Shanks would have a bit of an edge over Blackbeard.
3. Kaido Of The Beasts
Blackbeard is one of the strongest men, and Kaido is the strongest creature in the series, An classic battle between a man with two Devil Fruits and an unkillable monster.
Since Kaido wants to die so badly, he might try to fight Blackbeard because Teach is strong And Kaido is known for fighting with other Yonko’s like Shanks and Whitebeard.
2. Monkey D. Dragon
Dragon is strong, but Blackbeard has already picked a fight with him, so this battle is most likely to happen sooner or later. Dragon’s Powers has not been revealed yet, though we’ve seen him destroy an island with the wind.
Blackbeard was declaring war against the Revolutionary Army; it would be a good guess if they are going to battle against each other. Who will win is questionable as we yet have to see Dragon’s abilities but seeing Sabo the No 2. In the organization defeating Burgess the Captain of the First Ship of Blackbeard Pirates, they might have the chance to beat Blackbeard.
1. Fleet Admiral Akainu
The Fleet Admiral Sakazuki is one of the strongest characters in One Piece with his devil fruit power Magu Magu no Mi which allows him to control, create and transform into magma, makes one difficult opponent.
Akainu has a grudge against the powerful figures such has Dragon and Whitebeard, so Blackbeard is probably on top of Akainu’s list.
Blackbeard wants to trade Jewelry Bonney for a warship. His whole crew is present, But then Van Augur sees that admiral Akainu is commanding the marine’s ship and they run away rather than risking to get caught by him.
