Cotton, Pintel, Ragetti and the many unnamed Chinese pirates in the Motley crew under Captain Hector Barbossa at the end of Pirates of the Caribbean: At World's End are never seen after the films' end. Marty, Murtogg and Mullroy all left the crew, we know that. Murtogg and Mullroy joined the Crew of the Queen Anne's Revenge, and Marty joined the Crew of the Dying Gull. But, we have no idea what happened to the others. Did they die in Blackbeard's capture of the Black Pearl? Did they escape? Or did they simply resign beforehand? We now know that they weren't inside the bottle with the Black Pearl, as they weren't seen when it was released.
But then, Cotton's Parrot was seen inside the bottle in Pirates of the Caribbean: On Stranger Tides, but did not get released along with the Pearl like Jack the Monkey did. It may be possible they starved inside the bottle (the monkey didn't because he is undead), but there aren't any bodies in Pirates of the Caribbean: Dead Men Tell No Tales. Personally, I don't think that Disney would kill them off, especially Pintel, Ragetti and the Parrot. Post whatever you think in the comments!
