Captain Cook (クック船長) is a character in DEAD RED HOOD. He has the appearance of a stereotypical pirate.
He’s most likely based on Captain Hook from J. M. Barrie’s 1904 play “Peter Pan; or, the Boy Who Wouldn’t Grow Up”. He may be also related to James Cook (who was also a famous captain) since he’s called Captain Cook.
Disclaimer: DEAD RED HOOD isn’t out and it’s not in English yet, I had to put things through translation tools to obtain information for the post.
