At some unknown point in his life, Manray found himself in servitude aboard the Flying Dutchman, and gradually took on the appearance of a Manta Ray.
He remained in service to the Dutchman when Lord Cutler Beckett of the East India Trading Company Armada assumed command of the ship and its captain, and when dozens of East India Trading Company soldiers were stationed aboard the ship. Manray was seen holding an axe to a Company soldier's throat aboard the Empress. He looked up as Davy Jones walked past and discovered Ian Mercer in his cabin.
During the battle around Calypso's maelstrom, Manray, Finnegan and Broondjongen stood atop the crow's nest of the Flying Dutchman, yelling at the enemy and waving their weapons in the air. He fought alongside Piper and Finnegan later in the battle, dueling William Turner and Elizabeth Swann in sword combat during their impromptu marriage aboard the Black Pearl. He was eventually pushed far enough back that he began another sword fight with a different enemy. He likely reverted to his human form after Turner assumed command of the Dutchman. Whether he chose to remain in service aboard the vessel or left its crew remains unclear, leaving his final fate unknown.
