Anyone paying half attention to Pokémon these days probably knows who Lucario is, the Anubis-like Fighting Pokémon and star of the most recent Pokémon movie. After helping a mysterious adventurer rid Iron Island of Team Galactic with his Lucario, he'll give you an egg containing Riolu. This cute little jackal isn't bad by any means, but you'll still want to evolve him into Lucario as fast as humanly possible.

Evolves into Lucario when happy during the day.
