Doc Q

Doc Q (ドクQ, Doku Kyū) is the Blackbeard pirate crew's doctor, though, ironically, he has a sick body and needs his horse, Stronger (who is just as sick) to get around. His nickname is Shinigami (死神, "god of death" or "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.
