Iago is the secondary antagonist of Disney's 1992 animated feature film, Aladdin. He is a sarcastic, loud-mouthed and short-tempered parrot that served as Jafar's henchman during the latter's attempt to rule Agrabah. Iago's primary obsessions are riches and fame, which—coupled with his disdain for the Sultan's crackers—motivated his villainous deeds. Iago's role expanded significantly over the course of the saga, the most notable example being the 1994 direct-to-video sequel The Return of Jafar, in which Iago reformed and joined Aladdin and Jasmine as an anti-hero.
