Riolu was introduced in gen IV of Pokémon — just like its evolution, unusually! Here"s everything you need to know.

There are very few Baby Pokémon that were introduced in the same generation as another member of their evolutionary family. One of these is Riolu, which will evolve into Lucario. Both were introduced in Generation IV, with Lucario later receiving a Mega Evolution in Generation VI.

As a fan-favorite Pokémon, many Sword and Shield players will be looking to find and evolve a Riolu. It can be caught in Giant"s Cap in a blizzard, albeit with low odds of appearing. Here is how you can evolve that Riolu, plus a few more interesting things you might not have known about the Emanation Pokémon.

Like many Baby Pokémon, Riolu will evolve when leveled up with high enough friendship. However, there"s a catch. This evolution will only trigger during the day, so make sure you"re not trying at night. There are many ways to level up your friendship with a Pokémon, including giving it a Soothe Bell to hold, catching it in a Friend Ball or Luxury Ball, and much more.

If you don"t feel like going through the work to evolve a Riolu, Lucario can also be caught in the wild in rare instances, or found in Max Raid Battles.

Riolu has a few different abilities, including Steadfast and Inner Focus, which are actually almost-useless in the Mystery Dungeon series when combined. Due to the fact that Pokémon have both abilities in the Mystery Dungeon games, Riolu"s secondary ability will cancel out its first.

Steadfast is an ability that increases Riolu"s speed by one point when flinched. But, its second ability, Inner Focus, prevents it from flinching. Inner Focus will then prevent Steadfast from ever triggering unless Riolu is fighting an opponent with Mold Breaker or becomes cross-eyed.

Many Pokémon, especially Babies, will have huge stat boosts when they evolve, especially in specific stats. Riolu is a great example of this, as its special attack stats significantly increases when it becomes a Lucario.

Riolu"s base special attack stat is 35, which is paltry. However, Lucario"s base special attack is a fantastic 115. This is a huge increase upon evolution, taking Riolu from being feisty but terrible to a powerful and intimidating battler. It"ll come in handy for its signature move, Aura Sphere.

Speaking of Aura Sphere, it"s known for being Lucario"s signature move and is heavily associated with Lucario"s lore and design. Many people don"t realize that Riolu won"t actually be able to learn this special move before evolving.

However, there are some Riolu floating around out there that know this move. Inspired by the Aura Sphere Riolu from the anime, Kyle"s Riolu can be found in the Pokémon Ranger series. If a player captures this special Riolu in the Pokémon Ranger: Shadows of Almia game, they can then transfer it to the Generation IV games.

According to lore and the Pokédex entries for Riolu, it has an insane level of stamina. It"s said that it is a small but very powerful creature, with the ability to run for a very long time. Apparently, Riolu can run basically non-stop through the night, cresting three mountains and crossing two canyons in a single night.

The Pokédex states that this little guy is tough and hardworking, and that has exceedingly bountiful levels of energy. It humorously adds that taking it for a walk can be "challenging."

If you"re training Riolu to use as a permanent addition to your Pokémon team, you"ll have to make an adjustment after evolving it in terms of type matchups. Riolu has completely different weaknesses than its evolution Lucario, thanks to the addition of the Steel-type as it evolves.

Riolu is weak to Psychic, Flying, and Fairy. Lucario is not weak to any of these types and is instead weak to Fire, Ground, and Fighting. It"s interesting that it completely swaps weaknesses, having none in common with its evolution.

There is a legendary pantheon in the world of Starter Pokémon. The three Grass, Fire, and Water starters of each generation, plus some one-off starters like Espeon, Umbreon, and Pikachu. But, did you know that Riolu has actually been a starter Pokémon, too?

In the Pokémon Mystery Dungeon series, specifically Explorers of Sky, Riolu is available as a new starter Pokémon alongside Shinx, Phanpy, and Vulpix. Granted, it is a side game, but it"s still cool to see such a great and loveable Pokémon available from the start of a game in some capacity.

There have been a ton of Baby Pokémon introduced over the years, and a ton of Mega Evolutions (though not enough, as many believe). What you might not have noticed is that Riolu is the only Baby Pokémon that is part of an evolutionary family with a Mega Evolution.

The sheer stat difference between Riolu (base stat total: 285) and Mega Lucario (base stat total: 625) is staggering, and one of the sheerest jumps from the first stage to final stage.

As shown in the Pokédex, Riolu is a tough Pokémon with a ton of stamina. However, it also has a softer side. Riolu"s Pokédex entires state that it can see emotions in the form of aura. Multiple Riolu are capable of communicating with one another through this aura, and they can see "waves" of emotions emanating from humans and other Pokémon.

It can use this power to avoid dangerous foes, being able to read their vibe through their aura. Perhaps this is why it"s called the Emanation Pokémon.

There are very few Pokémon that can boast being available in every regional Pokédex, especially considering so many of them were cut during the Dexit scandal that plagues Sword and Shield.

However, Riolu and Lucario are some of the lucky Pokémon that can claim this status, being available in every regional "dex since their debut in the Sinnoh region. It shares this status with only a few other families. The other Sinnoh residents that meet these criteria are the Drifloon line, Mantyke, Weavile, and Leafeon and Glaceon.
