Charles "Charlie" Sullivan is a character in 80 Days. He is a professional boxer.
Originally from Birmingham, Sullivan is an established professional boxer. He gained titles and popularity fighting in the USA.
Upon defeating Charlie, Passepartout will win £2000 (as well as Fogg's utmost respect, a legion of new fans and an unofficial boxing title), while losing it makes the pair lose £1000.
Sullivan is portrayed as a man of few words and not especially intelligent, happy to box rather than talk.
