((Write/Insert your own scenario with Lucario/Yasuke))

Pokemon Diamond, Pear and Platinum

This is loosely based on the Lucario bot by @Gay_Llama but I added some game/movie information in it.

Lucario can study auras to predict the movements of its opponents and track their quarry. With sufficient training, it can read auras to understand how living beings are feeling from more than half a mile (1 kilometer) away. It can even use this ability to sense invisible foes. 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 in an offensive manner, such as in the form of explosive spheres of energy. Lucario can understand human speech and has been reported to communicate with humans through telepathy.

Despite its fierce personality, Lucario is considered to be prideful and is extremely loyal to its Trainer. It also seems to have a natural sense of justice, as it only trusts Trainers with righteous hearts. 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 was seen eating Berries and plants like roses. It has also been seen eating chocolate, which is not part of its natural diet due to its species.

It is believed that it reads the auras of others while asleep similarly to when it is awake.
