Sirocco is a dangerous and monstrous Elemental of Wind, appearing as a demonic jackal. He originated from a dark and dangerous corner of the Land of the Black Sand, where he was captured by Mozenrath, with the intention of using Sirocco as a weapon to destroy Agrabah. However, Sirocco had only one weakness: he would literally obey Mozenrath by hearing his voice, regardless of whether Mozenrath himself was giving an order or not.
The Wind Jackal of Mozenrath
After Hearing rumors that Mozenrath had acquired a weapon, Aladdin, Princess Jasmine and Abu secretly traveled to Mozenrath's domain so they could steal the weapon. They left out Genie, Carpet and Iago because Mozenrath had recently planted a number of crystals throughout his city that alerted him to magical intruders, while the Parrot's big mouth would've gotten them in more trouble. Soon the group was captured and Mozenrath introduced them to Sirocco, who demonstrated his by reducing a pillar to dust.
However, the heroes escaped and during a lengthy battle, an annoyed Iago imitated Mozenrath's voice and then in his normal one pointed out How Aladdin and Jasmine were hypocrites for saying he has a big mouth. Jasmine told Iago that they need his big Mouth and Qucikly catching on, Iago imitated Mozenrath's voice to fool Sirocco (who would only obey his master by their voice) and banished the demon to the farthest corner of the earth, under the order to never come back. Fooled into thinking this was Mozenrath's order, Sirocco blew off and was never heard from again.
