LeChuck is the main antagonist of the Monkey Island series and is depicted as an undead pirate with similiar qualities to villains such as Davy Jones and the Flying Dutchman as well as the generic "ghost pirates" of fiction.
LeChuck is feared by many and is obsessed with the female protagonist of the series, Elaine Marley, as well as gaining revenge on his nemesis (and main hero of the series) Guybrush Threepwood.
LeChuck is an intelligent and powerful villain who frequently uses voodoo magic in his schemes - which are often megalomaniacal in nature. Killing anything and anyone who stands in his way.
