Raising a Pokémon like Riolu is both rewarding and a bit tricky. If you’re wondering how to evolve Riolu, this guide breaks it down into simple, clear steps. Whether you’re new to Pokémon or just want to be sure, follow along.
What is Riolu and Why Its Evolution Matters
Riolu is a Fighting-type “baby” Pokémon introduced in Generation IV. It isn’t fully powerful in its base form, but when evolved into Lucario, it unlocks stronger stats, more moves, and better performance in battles. To evolve Riolu, you can’t just level it up anywhere or at any time — certain conditions must be met first.
Core Requirement: High Friendship (Happiness)
The key to evolving Riolu is its friendship (sometimes called happiness). Riolu must reach a high level of friendship with you before it can evolve. In most games, this is not “just above average” — you need something close to the maximum.
Ways to raise friendship:
- Let Riolu walk in your party (just having it with you on your adventure).
- Use items that boost friendship (for example, certain berries or vitamins).
- Avoid letting it faint in battles.
- Use it in battles (winning tends to help).
- Give it things like massages (where available in some games) or other in-game interaction features.
Once friendship is high enough, evolving becomes possible — but there’s an extra catch.
When Must Riolu Level Up? (Time of Day Constraint)
Even if friendship is maxed, Riolu will only evolve if it levels up during daytime. In most Pokémon games, “daytime” is a specific range of hours (for example, roughly 10:00 AM to 8:00 PM, though this can vary). If Riolu levels up at night or outside the allowed hours, evolution won’t trigger until the next appropriate time.
So the two conditions are:
- High friendship (near maximum)
- Level up during daytime
Both must be met in the same moment.
Game Variations & Evolving in Different Titles
Different Pokémon games may have slight tweaks, but the basic method is consistent:
- In modern games like Scarlet & Violet, Riolu still evolves with a very high friendship value and a level up during daytime.
- In titles like Brilliant Diamond and Shining Pearl, the same rule applies: friendship + daytime level up.
- In older games, you might see references to “happiness,” which is effectively the same.
- Some games offer bonus tools (like a Sooth Bell) that help friendship grow faster.
Always check the internal friendship score if the game offers that, to see how close Riolu is to evolving.
Tips to Speed Up Evolution
To make the process smoother, use some of these strategies:
- Use a friendship‐boosting held item, if the game allows (for example, a Sooth Bell or equivalent).
- Battle routinely with Riolu so it gains experience naturally.
- Avoid letting Riolu faint, because that often reduces friendship.
- Feed it friendship or experience items (if available).
- Perform any in-game features like massages or grooming, if the game includes them.
- Choose daytime training sessions so that when it levels up, evolution can trigger immediately.
With persistence, Riolu will finally evolve into Lucario.
Troubleshooting Why It’s Not Evolving
If Riolu refuses to evolve, check:
- Is friendship not high enough? It might seem close, but not quite there.
- Did the level up happen outside daytime hours?
- Did it faint recently, which lowered friendship?
- Is there a bug or quirk in that specific game version?
Once you correct the condition (e.g. wait till daytime, restore its friendship), level it up again and it should evolve.
