Arthur 3: The War of the Two Worlds (2010)

Picking up the events after the second film, Maltazard has assumed human size, and left Arthur in miniature. Accompanied by Princess Selenia and her brother, Prince Betameche, Arthur attempts to retrieve an enlarging potion from his house, which Maltazard seizes to enlarge his followers, whereafter Arthur returns to human form using an Elixir of Life given by a queen bee. Archibald convinces Darkos, Maltazard’s son, to change sides, and enlarges him with a second potion. Arthur and Darkos then confront Maltazard, until Selenia and Betameche shrink Maltazard back to his Minimoy size and Arthur captures him, while the U.S. Army overcome Maltazard’s forces. Maltazard thereafter remains a prisoner of Arthur’s family.
