Riolu / Lucario

Riolu is a small, blue, canine Pokémon. It has a black torso and legs, a blue tail, and a yellow collar. It has rounded bumps on the backs of its forepaws. It has a black "mask" and red eyes. It stands on its toes instead of its entire foot. It is sensitive to a special type of energy called Aura; however, it cannot fully use these powers, although it can still emanate these waves to communicate and sense them, albeit only in ripples. It has developed two black appendages that hang down from its head, which rise when Riolu reads or manipulates aura. It has even been seen that Riolu can sense and react to Aura before they even hatch. The aura emitting from Riolu's body grows even stronger when it is frightened or sad.
Like most Fighting-type Pokémon, Riolu naturally has superhuman strength, stamina, and endurance. It is capable of making long journeys on foot in a short amount of time. It is a playful, energetic, and loyal Pokémon. It is also known to be tough and hard-working. Riolu will read the minds of humans to assure whether or not they are pure of heart. As mentioned in the Sleep Style Dex, Riolu tends to sleep in a unusual position. This position is sitting up while not lying down, similar to Lucario. It is believed that Riolu is pushing itself hard and dreaming of the day it evolves into Lucario.

They communicate with one another using their auras. They are able to run all through the night.

Lucario is a bipedal, canine-like Pokémon with predominantly blue and black fur. It possesses a short, round spike on the back of each forepaw, in addition to a third on its chest. It has red eyes, a long snout, and ears. When its mouth is open, two pairs of pointed teeth, one in the upper jaw and one in the lower, can be seen. It possesses cream-coloured fur on its torso and blue fur on its thighs that resemble shorts. It has a medium-length tail of the same blue colour as well. It stands on its toes rather than on its entire foot. It has developed four black appendages that hang down from its head, which rise when Lucario reads or manipulates aura, a special energy that it senses. Lucario can use its powers to create a staff in form a bone and use it to fight.
Lucario can study auras to predict the movements of its opponents and track their quarry. With sufficient training, a Lucario can read auras to understand how living beings are feeling from more than half a mile (1 kilometre) away. However, it sometimes ends up learning information that it would not like to know, causing it to get stressed out easily. It also has the power to manipulate this energy offensively, in the form of explosive spheres of energy. Lucario can understand human speech and has been reported to communicate with humans through telepathy.
Lucario is considered to be prideful and is extremely loyal. It is an exceptionally rare Pokémon that usually lives deep in mountains very far from people to improve their skills. Lucario are primarily carnivores, hunting their prey in packs, though one Lucario was seen eating Berries and plants like roses. It has also been seen eating chocolate, even though chocolate is not part of its natural diet. Lucario never lowers its guard, even when sleeping. It is believed Lucario's reading the aura of others is similar to when it's awake.

Lucario

It’s said that no foe can remain invisible to Lucario, since it can detect auras—even those of foes it could not otherwise see.
