Piper was a crew member of the Flying Dutchman, serving Captain Davy Jones around the time Lord Cutler Beckett assumed control of the Flying Dutchman and its crew.. His body was almost entirely covered in tube coral.
At some unknown point in his life, Piper found himself in servitude aboard the Flying Dutchman under Captain Davy Jones, and his body was gradually covered in Tube coral.
During the battle of Calypso's maelstrom, he fought Will Turner and Elizabeth Swann, but was defeated. He jumped at Elizabeth, but Will cut him down. When they were married during the battle, Piper could be seen killing a Chinese pirate as they kissed.
It was likely that he reverted to his human form when Turner became captain of the Dutchman. In battle, he was known to use an Arabic scimitar and war hammer.
