Jack is Barbossa's pet White-headed_Capuchin, named after Jack Sparrow to mock him after Sparrow got marooned on a deserted island. During The Curse of the Black Pearl, Jack, like the rest of the crew, is cursed, turning undead in lunar light and bestowed with indestructibility. Jack temporarily becomes mortal again when Will lifts the curse, though he later steals another coin and becomes cursed again.
