Ryder Sundry is the daughter of one of the late Marine captains stationed in the Grand Line. Her goal is to prevent any pirate from finding the legendary One Piece and if they do manage to find it, she will capture the next Pirate King/Queen and be known as a hero. Due to the loss of her father at an early age, she became a cross-dresser so that she can continue in his footsteps as the "son" he never had. Sundry is the leader of a World Government secret assassination group much like the rumored Cipher Pol number 9. She is also the user of the Onibi Onibi no Mi.
