Evil pirate captain from Peter Pan. Captain James Hook is a fictional character, the antagonist of J. M. Barrie’s play Peter Pan; or, the Boy Who Wouldn’t Grow Up and its various adaptations, in which he is Peter Pan’s archenemy. The character is a pirate captain of the brig Jolly Roger; Barrie describes him as Blackbeard’s former bo’sun. His two principal fears are the sight of his own blood (supposedly an unnatural colour) and the crocodile who pursues him after eating the hand cut off by Pan. An iron hook replaced his severed hand, which gave the pirate his name. After getting a taste of Hook, the crocodile pursues him relentlessly, but the ticking clock it has swallowed warns Hook of its presence.
