At the beginning of the film when it accidentally flashed back too far into Kuzco's past, it was also revealed that he had a stuffed doll as a treasured toy, and eventually threw a fit as a baby when he accidentally broke it while hugging it, only to cheer up when what were presumably his caretakers promptly replaced it with several just like it (an early hint at how he had been spoiled-rotten). It is revealed that Kuzco and his father share two things: a llama birthmark and the same necklace. Since Yzma claims to have raised Kuzco, it is possible that his mother passed away as well, rendering him an orphan.
According to Kuzco and Yzma, he was lost at sea on a trip when Kuzco was just a baby thereby granting the throne to Kuzco.
He is a strong, muscular man, and was emperor before Kuzco. Not much is known about his past except in The Emperor's New School episode ' Father O' Mine', where Kuzco's real father appears in a flashback.
