Riolu is Emile's un-nicknamed Riolu in Pokémon Platinum.
Emile had constantly carried the Egg around with him until Riolu hatched. During the time he went back and forth between Celestic Town and Mt. Coronet while trying to find Feebas, Riolu unexpectedly hatched while Emile was making a point, prompting him to shout, "Now is not the time to be born Riolu!"
Riolu was one of several Pokémon to appear, and Emile showed him, due to half of the his Pokémon that he caught in the LP were supporting characters.
