Unfortunately Not a Real Pony

Disney's Aladdin has no facial hair, despite being too poor to afford razors or trips to the barber. (I think Muslim law forbids men from shaving too, so assuming he's devout he likely wouldn't even if he could.)

Since other men in the cartoon, such as the sultan and Jafar, have facial hair, one can assume that Aladdin doesn't grow any for some reason.

Conclusion: he's trans.
