Fitzwilliam P. Dalton III

Fitzwilliam P. Dalton was a pirate who joined Jack Sparrow's crew at the beginning of his hunt for the Sword of Cortés. He became something of a rival for Jack onboard the Barnacle, often disagreeing with the captain.

Joining a crew
Fitzwilliam hailed from a noble family, the Daltons. At the beginning of Jack Sparrow's quest, Fitzwilliam fled his home in order to avoid an arranged marriage. Before Jack and Arabella Smith left Salty Cove aboard the Barnacle, he insisted on coming with them, besting Jack in a sword fight to prove his worth. Dalton was with the crew of the Barnacle when they visited the City of the Dead and defeated Captain Torrents.

Adventures with Jack
When the Barnacle's crew fell under the sway of the Sirens, Dalton demanded that Jack take him to the nearest port, so he could join the British Royal Navy and bring honor to the Dalton name. Eventually, Jack was forced to tie Dalton to the mast, and later negotiated with the mermaids to release his crew from their delusions.

Dalton continued his adventures with Jack. He helped him find the Sword of Cortés as well as the Sun-and-stars amulet.

Ironically, at the end of a few adventures Fitz was the only crewmember to remain with Jack. His pocketwatch was actually the Timekeeper, which Davy Jones strongly desired in order to ensure he and Calypso wound up together. When Jones first forced himself aboard the Barnacle in order to take the timepiece, Jack cleverly used its power to escape safely with Fitz. The two rowed to a nearby island and were captured by unfriendly warriors dressed as Aztecs. Eventually they managed to escape and discovered they were back at the City of the Dead and had traveled back in time.

After traveling back in time, the goddess Chantico appeared to Fitzwilliam and Jack after they had been hurled into her volcano by Captain Torrents. She explained that their use of the Timekeeper has messed up time and gave them twelve hours to set it right. The two of them managed to find Tia Dalma who told them that the Timekeeper must be placed and removed from the grip of someone who doesn't belong to their time. Together, they managed to do this with Stone-Eyed Sam.

Betrayal
After the adventures with the Timekeeper were over, Fitzwilliam revealed that he was really a British Royal Navy spy who used Jack in order to find his father, Teague, intending to ultimately deliver them both to their deaths.

It is unknown of whatever happened to Fitzwilliam.
