The Duke of Weselton, sometimes mockingly referred to as the Duke of Weasel Town, is the secondary antagonist of Disney's 53rd full-length animated feature film Frozen.
He is the conniving, egotistical and manipulative Duke of one of Arendelle's neighboring kingdoms, Weselton, and seeks to exploit Arendelle's goods for his own benefit. He has two guards at his disposal named Erik and Francis, willing to assist him in whatever he needs. However, the Duke ends up being played by a far greater threat, Prince Hans.
He was voiced by Alan Tudyk, who also played Turbo/King Candy in Disney's Wreck-It Ralph, Duke Weaselton in Disney's Zootopia, and Alistair Krei in Disney's Big Hero 6 and Big Hero 6: The Series.
