He is a white male horse with a grey brown mane.
Previously Sahara belonged to Sultana and she was the only one who could tame Sahara, even though many have tried and failed. Sahara doesn't even allow the Sultan to come near him unless he has an apple for him. The Sultan states that Sahara was Jasmine's Mother's favorite horse and he visits Sahara every day to be reminded of her beauty, courage and strength.
Sahara is not very friendly, easily angered, very fiesty and haughty. He has no problem being aggressive and violent to anyone who tries to tame him or gets to close to him.
A dizzy Abu accidently lets Sahara out of his stable. Jasmine, Abu, Carpet and Iago go in search of him in order to prevent Hakeem from getting fired. After searching for some time, they find Sahara at an Oasis in the middle of the desert and tames him, returning in time to save Hakeem from losing his job.
