Osiris is an Egyptian sun deity.
Osiris was seemingly invited to the wedding of Aladdin and Jasmine. Genie tried to get an interview with him, but Genie's cameras only angered him. However as many of the other ancient guests (such as Caesar, Cleopatra, Moses, etc) were just poofed up by Genie on the spot or Genie in disguise, it is never made clear if Osiris was actually there or not.
- This character is actually either Ra or Horus, the falcon-headed sun deities of ancient Egypt, while Osiris was an overseer of the Underworld who had a human head.
