Chaos is the spirit of mayhem in the Aladdin universe. While not technically a villain, Chaos is exceedingly powerful and does not adhere to any system of reality or morality. He is a minor player in the second Disney Vs Non Disney Villains War.
Disney Vs Non Disney Villains - Part Two
Saving Pain and Panic
Chaos interrupts a battle between Hades's sidekicks, Pain and Panic, and Demongo. Chaos stops Demongo from killing the hapless imps, freeing all of Demongo's trapped souls and leaving him defenseless. But Chaos doesn't stoop to killing his enemy. He has bigger business to attend to. Along with Loki and Nemesis, Chaos pledges his aid to Hades for the events of the war; they, too, want to see the demise of Eris, Hades's mortal enemy.
The Battle of the Underworld
During the Battle of the Underworld, Chaos transforms into a tornado and turns Discord back into a statue. Later, when Eris is about to destroy Hades, Chaos interrupts her attack. In her rage, she destroys him instead.
Cartoon Villains War
Having been freed from his stone prison, Discord was welcomed back to the world of the living by his brother Aku. As the two brothers caught up, Discord discovered just how long he had been gone, and learned that in his absence, another creature of chaos had risen to take his place. Wanting to stretch his legs and remind the mortals of his power, Discord went to confront this new deity at his temple, where he challenged him to a battle of chaos. The creature, known only as Chaos, accepted this challenge, thinking it might be amusing. Discord began by transforming nearby woodland creatures into fearsome beasts to fight on his behalf. However, Chaos found himself in the strange position of restoring order for once, and transformed Discord's monsters back into harmless critters. Angered that Discord had pushed him to go against his nature in such a manner, Chaos pulled out all the stops and began to unleash a chaotic storm upon his rival. Terrified by this display and surprised by Chaos's power, Discord begged for mercy. Amused by how quickly Discord had been defeated, Chaos let his guard down for a moment. This turned out to be a mistake, as Discord had merely been feigning weakness, and took the opporunity to unleash his full power on Chaos, erasing him from existence.
