Hello, I'm a Pokémon enthusiast with extensive knowledge of the game mechanics and breeding process. Let's dive into your question about breeding with Riolu.

In the Pokémon games, Riolu is a single-type Fighting Pokémon that cannot breed with itself to produce more Riolu. However, Riolu is part of the Field Egg Group, which means it can breed with other Pokémon in the Field group to produce Field Eggs. Additionally, Riolu is also in the Human-Like Egg Group, so it can breed with other Pokémon in that group as well.

When you breed a Riolu with a compatible Pokémon from either the Field or Human-Like Egg Group, there are a few factors to consider:


1. Masuda Method: If you use a Riolu from a game with the same language as the parent, the chance of getting a Shiny Riolu is increased, but it's still relatively low.


2. Destiny Knot: If you want to pass down an IV (Individual Value) from the parent to the offspring, you can use a Destiny Knot, which will also increase the chances of passing down five IVs instead of the usual three.


3. Everstone: If you want to ensure that the offspring will have the same nature as the parent, you can give the parent an Everstone.


4. Breeding with a Ditto: If you're having trouble finding a compatible Pokémon, you can breed Riolu with a Ditto, as Ditto can breed with any Pokémon that is not in the Undiscovered, Baby-Only, or Mythical Egg Groups.


5. Daycare: Place Riolu and the compatible Pokémon in the Pokémon Daycare and collect the eggs they produce.

Remember that the offspring's species will always be the one that is not in the first slot, so if you want a Riolu, make sure to place the compatible Pokémon in the first slot and Riolu in the second.

no. You need to evolve the Riolu to Lucario before breeding. so how do i get a riolu with psychic and modest nature? Breed a Lucario with a Modest Ditto holding an everstone and the offspring will have 50% chance of being Modest.read more >>
