* Riolu is a pre-evolutionary Pokemon: Riolu evolves into Lucario, and Lucario is typically obtained later in the game, often through special events or side quests.
* Game progression: The game design often restricts access to certain Pokemon until you reach a certain point in the story to balance the difficulty and experience.
Here are some ways you can get Riolu in Pokemon games:
* Events: Keep an eye out for special events in your game that may distribute Riolu as a gift or through special codes.
* Trading: You can trade with other players online or locally to obtain a Riolu. Make sure the other player has a Riolu to trade.
* Breeding: If you have a Lucario, you can breed it with a compatible Pokemon to obtain a Riolu egg.
Remember: The availability of Riolu and how you can get it depends on the specific Pokemon game you're playing. Make sure to check the game's information or online resources for specific details on obtaining Riolu.
