Iago is the secondary antagonist in the musical adapation of Aladdin, based on the character of the same name. Instead of being a parrot, he is featured as Jafar's human assistant in the musical. He also sings, taking part in Jafar's song "Diamond in the Rough", unlike the original film, where he does not sing at all.
Iago's fate also differs in the musical; whereas in the film, Iago is dragged by Jafar into the lamp, in the musical, Iago is arrested for treason and his role as royal adviser is taken by Babkak, Omar, and Kassim (three friends of Aladdin) subsequently.
