Publisher's Synopsis
The Blackbeard Pirates are an extremely infamous and powerful pirate fleet led by Emperor Marshall D. Teach, better known as "Blackbeard", and one of the main antagonist groups of the series.
Blackbeard was originally a member of the Whitebeard Pirates (and Portgas D. Ace's subordinate), until he murdered one of his crewmates over a Devil Fruit and defected, heading out on his own and forming his own crew. Blackbeard was Crocodile's replacement among the Seven Warlords of the Sea, having captured the wanted pirate Ace to obtain this position, but resigned after forfeiting the privilege by raiding Impel Down and recruiting notorious prisoners for his crew from Level 6.
During the timeskip, after clashing with the remnants of the Whitebeard Pirates led by Marco the Phoenix and emerging victorious, Blackbeard usurped the status of the deceased Whitebeard as one of the Four Emperors.
