In the Pokmon video game series, Riolu is a Fighting-type Pokmon that can evolve into Lucario. To evolve Riolu into Lucario, the player must increase Riolu’s friendship level to a certain point and then level it up during the day. Friendship level can be increased by battling with Riolu, using it in Pokjobs, and giving it certain items.
Evolving Riolu into Lucario is important because Lucario is a much stronger Pokmon than Riolu. Lucario has higher stats, learns more powerful moves, and can Mega Evolve into Mega Lucario. Mega Lucario is one of the most powerful Pokmon in the game, so evolving Riolu into Lucario is a worthwhile goal for any Pokmon trainer.
