"One Eye" is a traveling thief within the Seven Deserts.
True to his nickname, he is a one-eyed thief, whose right eye is perpetually closed presumably due to losing it under unknown circumstances. He appears to be quite aged and frail-looking, but is quite agile for his age and usually wields either a scimitar or a wooden club as a weapon.
When Aladdin, Jasmine and their friends are traveling across the deserts searching for the Tree of Renewal in order to cure Jasmine of her Naga curse, they are confronted by a band of three thieves, with One Eye now in their ranks. Theses thieves control a deadly Gypuuk which they used to constrict Aladdin and the rest in order to surrender their valuables, however Jasmine (using her new monstrous form) is able to intimidate the thieves and force them to call off their gypuuk and flee.
At an unknown point after his last encounter, One Eye was recruited into the infamous Forty Thieves by Cassim. He would then aid his comrades in the raid on the Sultan's Palace in order to obtain The Oracle's Scythe for Cassim. He and the rest of the Forty Thieves later happily welcomed Aladdin to their order after his initiation. However One Eye's time in the Forty Thieves would not last, as he and the majority of the thieves were later betrayed by Sa'Luk and imprisoned in Agrabah's dungeon.
