Robin Nico

Robin is the seventh member of Straw Hat's Crew. She had a bounty of 79 million beri since she was eight years old, during an incident in which she supposedly destroyed six Buster Call ships through the use of the powers she gained by eating the Hana Hana no Mi (Flower Flower or Blooming Blooming Fruit). The fruit's power enables her to conjure up multiple replicas of her body parts (most often her arms) upon any surface she is able to see making her very powerful and dexterous as a result. Robin joined the Straw Hat Pirates after Luffy saved her life, or (how she states it) Luffy forced her to live when she wanted to die. To atone for his crime, Robin demands that Luffy allow her to join his crew, to which he complies leaving every other crew member except Sanji in shock. Although feared at first, she is quickly accepted and viewed as a comrade by the crew.
