Ghost Wake Pirates

The Ghost Wake Pirates is a small pirate crew that currently consists of four very different people. The captain being Rena D. Stryder is a former Marine Captain who has become disillusioned with the Marines and the World Government. Chrysalia Mnemosyne is a former Celestial Dragon slave, Kaiji Shun is a pacifistic doctor, and Xenon is a cyborg (human/robot) who has had his memories repressed by an evil scientist when he was kidnapped as a child. The crew as a whole is known as the Ghost Wake Pirates due to the ghost-like apparitions that seem to follow Rena when she's in battle under her hybrid transformation as a side-effect of her devil fruit.
