Blackbeard Pirates

The Blackbeard pirates (黒ひげ海賊団, Kurohige Kaizokudan) are fictional pirates from the anime and manga One Piece, led by Marshall D. Teach, better known as "Blackbeard".

Their captain, Blackbeard, was originally a member of Whitebeard's band of pirates (and Ace's subordinate), until he killed one of his crewmates and defected, heading out on his own and forming his own crew. Blackbeard is Crocodile's replacement among the Shichibukai, having turned in Firefist Ace to gain this positon.

Part in the Story
Blackbeard's flag is that of three skulls--one looking left, one looking forward, and one looking right. The first time the crew is mentioned, they are said to have ransacked the kingdom of Drum. Upon seeing their immense power, the cruel and cowardly king, Wapol, fled without even fighting back. In Arabasta, when the Straw Hats meet up with Portgas D. Ace, it is revealed that Ace is hunting him down for what he did to his crewmates.

Laffite marks the first visual appearance of the crew by appearing at Mariejoa to recommend Blackbeard to replace Crocodile as one of the Seven Warlords of the Sea. The other crewmembers are first seen in Mock Town of the island Jaya, playing several "games" to see how fate works out. When Luffy meets Blackbeard himself in a bar, they at first seem to have the exact opposite opinions. While Luffy hates the bar's pie, Blackbeard loves it, and while Luffy loves one of the bar's drinks, Blackbeard hates it, which leads to them challenging each other to a fight, but they decide not to go through with it when Nami points out that they are fighting for no reason. Later on, after the Bellamy Pirates taunt them for believing in Sky Island, Blackbeard assures the Straw Hats that it does exist and in response to the notion of the "New Age", states that people will never stop dreaming. Because of this, it is not yet known whether Blackbeard is truly evil or whether he is just misguided. When Blackbeard finds out about Luffy's high bounty, he and his crew try to capture him, but the Straw Hats are launched into the sky by Knock-Up Stream before they can make an attempt.

After the incident at Enies Lobby, Blackbeard decided to capture Luffy, who now has a bounty of 300,000,000. However, Ace finally caught up with Blackbeard at Banaro Island, and the two fought fiercely, with Blackbeard victorious. Blackbeard then turned Ace in to acquire his position for the Shichibukai. This event also triggered the start of the war with Whitebeard, as the Marines publicly announced Ace's execution.

During the preparations for the war, Blackbeard was seen sitting along with his fellow Shichbukai. However, roughly five hours before the execution, he and his crew stole a Marine's ship from Marineford and set off to Impel Down, and broke in for reasons yet unknown.

Crew Strength
The Blackbeard Pirates are much stronger than normal pirates depicted so far in the story. Van Auger shot a flock of seagulls from a distance so far the Straw Hats couldn't even see the island he was on. He is able to predict where a bullet is going to hit, and can run at an amazing speed to avoid it. Jesus Burgess is a wrestling champion and won every fight while he was in Mock Town. He is also able to throw buildings with much ease and at impressive distances. Laffite was able to sneak into the World Government headquarters of Mariejoa during a meeting between several high-ranking Navy officials and three Shichibukai members completely undetected until he spoke up, a feat made even greater by his wearing tap shoes. Doc Q and his horse Stronger has yet to show any abilities, and for the matter appears to be weak with their sickness. However, it is doubted Blackbeard would accept a weakling into his crew. The crew captain, Blackbeard himself inflicted a permanent scar on the face of Red-Haired Shanks - one of the Four Emperors and one the strongest pirates in the world and effortlessly, even casually defeated Sarquiss and finally he was able to defeat Firefist Ace and Thatch, the Second and Fourth Division Commanders of the Whitebeard Pirate Crew, respectively. Due to his eating the Yami Yami no Mi, he might be able to defeat any devil fruit user in the world as most Devil Fruit users tend to rely heavily on them. Their attack on Drum Island was overwhelming to the point that it forced its king Wapol to flee the country entirely. And lastly, the fact they took a direct attack from Ace and managed to get up after it shows they are stronger then normal.

Other Information
They believe heavily in fate and luck, using often cruel measures to see how destiny plays out. One example is Van Auger, who shot a group of seagulls just to see the ones destined to die slow and painful deaths. Another example is demonstrated by Jesus Burgess, who challenges random people to a fight to see who wins. Doc Q also handed out apples in Mock Town to see who was unlucky enough to get ones that exploded after one bite and who did not. Even when they chase after Luffy to the Knock-Up Stream, his escape was put down to fate.

While it has never been stated by Oda where the influence of their flag comes from, the image of the 3 heads appears as a classic depiction of Cerberus. The three heads of Cerberus are suppose to see the past, the present and the future and Cerberus was also the guardian of the gates of Hades. This happens to tie in with the crews views of fate and destiny as well as their often deadly methods for seeing how fate plays out and may be the reason behind the three skulls. It may also be a depiction of the Moirae, the three goddesses of Fate.

All members of the crew appear to be massive humans, not unlike Aokiji or Whitebeard. Teach, Burgess, and Doc Q are big characters, while Van Auger and Laffite are quite tall as well.

Trivia

 * At least four of the crew are apparently named after four real life pirates (Blackbeard, Van Auger, Jesus Burgess, Laffite).
