The Crew Continued
Doc Q (ドクQ Doku Kyū) is the crew's doctor, though ironically, he has a weak body and needs his horse, Stronger (who is just as sick) to get around. His nickname is 'Shinigami' which literally means God of Death. Most fans however refer to him as the 'Grim Reaper'. He meets Luffy, Zoro, and Nami during the Jaya arc, while in Mock Town. After the Straw Hats help him get back on his horse, he offers Luffy an apple from the basket he is carrying. Unbeknownst to Luffy, Doc Q had been offering explosive apples to other pirates in Mock Town, who would then explode once they ate it. Luckily for Luffy, he picks a dud, and Doc Q tells him he is very lucky before riding off. Strangely, he is seen rowing on Blackbeard's ship, even though his body is supposedly sick and weak. Also, in the manga, both him and Stronger are seen swiftly running away from Blackbeard's and Ace's climatic fight, with the rest of Blackbeard's crew. While he didn't fight Ace, Doc Q (and Stronger) easily shrugged off one of Ace's attacks.
Lafitte (ラフィット, Rafitto) first appeared when he joined, unannounced and uninvited, at the meeting of the Shichibukai and the Marines to determine the replacement for Sir Crocodile in order to recommend his captain. He used to be a policeman in West Blue, but he became a pirate after being exiled from the police force and West Blue for being excessively violent and cruel. He is incredibly pale and sickly looking, and is usually tap-dancing, even when walking or running. Despite these impediments Lafitte is shown to be very stealthy and agile, as not even "Hawkeye" Mihawk noticed him before he spoke up (a remarkable task, for he wears tap-dancing shoes).
His name may have been inspired by Jean Lafitte, a famous real-life pirate. He may have also been inspired by the inhumanly fast Berthold from the 1988 The Adventures of Baron Munchausen, as he was able to get to the Marine Headquarters without the crew and back to Barano Island in what may have been a short time. He may also be a reference to Alex DeLarge from A Clockwork Orange, given his style of dress and stated "ultra-violent" habits.
In the English version of the PS2 and Gamecube game, One Piece Pirates' Carnival, Lafitte is named Raffit.
The Ship and the Flag
Blackbeard's flag is that of three skulls--one looking left, one looking forward, and one looking right.
The crew's ship is a giant raft with no extras except a number of cannons in the center of the logs. During the Jaya arc the ship was torn apart by Knock Up Stream, But considering it was made of logs and the fact Blackbeard and his crew are on the move it's possible the ship was repaired.
