Lucario

Lucario are very reserved, prideful, and very serious Pokémon and also extremely loyal to their trainers, but they can be also friendly and cooperative with strangers and their Pokémon. In the wild, Lucario live in packs and they are primarily carnivores, though domesticated ones can be seen eating plant-based foods as well as other human food such as chocolate. Lucario are sensitive to a special type of energy called Aura. The black appendages on the back of their heads are used to detect the Auras of creatures and objects around them. With their ability to sense the Auras in all things around them, they can navigate and track through telepathic methods. They can also guide the waves of an Aura offensively to create small balls of energy such as Aura Spheres. Lucario is also able to understand human speech. Lucario can use aura to communicate or sense its surrounding environment as well. Aura is also useful for them to detect the strength and capabilities of their faraway foes.
