Nightin

Nightin is the doctor of the World Pirates.

Abilities and Powers
As a member of the World Pirates, she can be assumed to be a very skilled doctor. She is also a skilled user of Kampa Kenpo, she was used to be called the "Goddess of Kampa Kempo". She was skilled enough to fight on par with a member of the Shichibukai, Boa Hancock, but was defeated when she succumbed to Hancock's charms.

History
Her past before joining the World pirates is unknown. She was one of the main members of the World pirates. She and her crewmembers were seen fighting and winning against navy and pirates alike. When the World Government finally found a way of defeating them, she is present when their captain is betrayed and shot multiple times by his own crew members. She and the others were commanded by Byojack to escape and survive.

After Byrndi Wolrd escaped, she and her fellow crew members were present and fetched their captain with their dream ship.

When Boa Hancock and Monkey D Luffy entered their ship, she was in her room and she told Byojack that she will take care of Boa Hancock. She then fought the Pirate Empress, seemingly having a way of countering the power of Mero Mero no Mi by eating her bitter herbs so she wouldn't turn to stone. She then used a technique which gave her a youthful appearance and greater fighting abilities. However, she eventually could not eat any more of her bitter herbs and thus could no longer resist Hancock's beauty and was quickly turned to stone.

After the climatic battle between their captain and Monkey D Luffy, the Marines led by Sakazuki attacked and made their ship explode. She is assumed to be killed with her fellow crew members.
