LeChuck is the main antagonist of the Monkey Island video game series.

He is an undead, ghostly pirate captain who 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 protagonist 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.
