Yes, Riolu cannot breed. This is a fundamental rule within the Pokémon universe. Riolu, the pre-evolution of the powerful Lucario, is classified as a “baby Pokémon,” and these Pokémon have a specific restriction that prevents them from breeding. This rule applies regardless of whether you pair Riolu with another Riolu, a Ditto, or any other breedable Pokémon. The inability to breed is a defining characteristic of baby Pokémon within the core Pokémon games. Understanding why requires a deeper dive into the mechanics of breeding within the Pokémon world.
Why Can’t Riolu Breed? The Mechanics of Pokémon Breeding
The core reason Riolu can’t breed boils down to its classification as a baby Pokémon. This status isn’t just arbitrary; it’s intrinsically tied to the game’s breeding mechanics.
Baby Pokémon Status
- Definition: Baby Pokémon are typically the first stage in a two- or three-stage evolution line. Examples include Pichu (pre-evolution of Pikachu), Magby (pre-evolution of Magmar), and, of course, Riolu (pre-evolution of Lucario).
- Breeding Restriction: These Pokémon are inherently restricted from breeding. The game’s code prevents them from generating eggs.
Egg Groups and Compatibility
- Egg Groups: Every breedable Pokémon belongs to one or two “Egg Groups.” These groups dictate which Pokémon can breed with each other. For example, Pokémon in the “Field” egg group can breed with other Pokémon in the “Field” group.
- Ditto’s Role: Ditto is a unique Pokémon that can breed with nearly any Pokémon, regardless of Egg Group, except for those in the “No Eggs Discovered” group.
- No Eggs Discovered Group: This group is a catch-all for Pokémon that cannot breed, including baby Pokémon, most Legendary Pokémon, and certain special form Pokémon. Riolu is part of this group.
The Evolutionary Requirement
The design of breeding within the Pokémon universe encourages evolution as a prerequisite for breeding certain Pokémon. This means that players must evolve Riolu into Lucario before they can begin breeding and attempting to influence factors like Individual Values (IVs), nature, and egg moves. This system adds an extra layer of gameplay, requiring players to invest time and effort into raising and evolving their Pokémon before optimizing their offspring.
Gameplay Implications
The inability of Riolu to breed impacts gameplay in several ways:
- Acquisition Difficulty: It often makes Riolu harder to obtain in the first place. In some games, Riolu is only available through specific in-game events or by evolving a Lucario and breeding it.
- Breeding Strategy: It forces players to focus on friendship and evolution mechanics. To get a Riolu egg, you need a Lucario, and breeding a Lucario to get a Riolu is the only option.
- Shiny Hunting: It can make shiny hunting more challenging, as you can’t simply breed a bunch of Riolu eggs until you get a shiny one.
Frequently Asked Questions (FAQs) about Riolu and Breeding
Here are some frequently asked questions related to Riolu and breeding in the Pokémon games:
1. Why won’t my Riolu and Ditto breed?
Riolu is a baby Pokémon and is therefore unable to breed. Ditto can breed with almost any Pokémon, but it cannot breed with those in the “No Eggs Discovered” group, which includes Riolu.
2. Can Riolu breed with another Riolu of the opposite gender?
No. Riolu’s inability to breed isn’t just about Ditto; it cannot breed with any Pokémon, including another Riolu.
3. How do I get a Riolu egg?
You need to evolve a Riolu into Lucario and then breed Lucario with a compatible Pokémon (like Ditto) or another Lucario. This is the only way to obtain Riolu eggs.
4. What are the steps to breed a Riolu?
- Evolve a Riolu into a Lucario.
- Place Lucario in the Day Care or Nursery with a compatible Pokémon (Ditto or another Lucario).
- Wait for an egg to be produced.
- Hatch the egg to obtain Riolu.
5. What Egg Group does Lucario belong to?
Lucario belongs to the Human-Like egg group and, in some games, the Field egg group.
6. Can you breed two Lucarios together?
Yes. If you breed two Lucarios together, the resulting egg will contain a Riolu. The Day Care or Nursery will provide you with an egg after you’ve traveled a certain number of steps.
7. Does the gender of the Lucario matter when breeding with Ditto?
No, the gender of Lucario does not matter when breeding with Ditto. Ditto can breed with Pokémon of any gender, or even genderless Pokémon.
8. Can I influence the IVs of the Riolu I get from breeding?
Yes. You can use items like the Destiny Knot (to pass down IVs from the parents) and Everstone (to pass down the nature) to influence the IVs and nature of the Riolu offspring.
9. What is the best nature for a Riolu or Lucario?
The best nature depends on how you plan to use Lucario. Common choices are Adamant (attack up, special attack down) for physical attackers, Timid (speed up, attack down) or Modest (special attack up, attack down) for special attackers, and Jolly (speed up, special attack down) for mixed attackers.
10. Is it possible to get a Shiny Riolu through breeding?
Yes. You can get a Shiny Riolu through breeding if you are lucky. The odds of hatching a Shiny Pokémon are influenced by the Shiny Charm and the Masuda method (breeding Pokémon from different regions).
11. What are Egg Moves, and how do they relate to Riolu breeding?
Egg Moves are moves that a Pokémon can inherit from its parents when hatched from an egg. If one of Lucario’s parents knows a specific move that Riolu can learn as an egg move, the hatched Riolu will know that move.
12. Can Zygarde Breed with Ditto?
Yes, Zygarde can breed with Ditto. They always produce Zygarde Cell eggs, irrespective of their form.
13. Is Riolu Based on a Dog?
Yes, Riolu is a black and blue, dog-like Pokémon nearing two and a half feet. Its appearance is similar to its evolved form Lucario, though there are some differences. Lucario’s appearance is based on Egyptian god Anubis. It resembles either a type of dog (Dobermann) or a jackal.
14. Is there a Female Riolu?
Yes, there is a female Riolu. Gender ratio is 1:7 female:male. That is a smaller chance of obtaining a female Riolu but it is possible.
15. What Pokemon Cannot breed with Ditto?
Ditto has the unique ability to breed with any Pokémon in the game, except those that belong in the No Eggs Discovered Group. This group contains baby Pokémon, certain special form Pokémon (like Cosplay Pikachu), and nearly all of the Mythical and Legendary Pokémon from throughout the series.
Concluding Thoughts
The inability of Riolu to breed is a specific characteristic, as it adds another layer of depth to the mechanics of raising and optimizing Pokémon teams. While this restriction might seem inconvenient at first, understanding the nuances of breeding and evolution within the Pokémon world will help. Players must learn how to take advantage of these mechanics to obtain the Pokémon they desire. So, while you can’t directly breed Riolu, evolving one to Lucario opens up a world of possibilities for creating the perfect Riolu offspring.
