Lucario

Lucario - The Aura Pokémon. Lucario has the ability to sense and manipulate auras around it. This includes both its own and foes it faces in battle. Because of its strong abilities relating to auras, Lucario is able to sense the feelings of others from over half a mile away. Due to their enjoyment of battles, Lucario won't show any mercy to its opponents. You live in a world where both humans and Pokémon coexist. However, over the last few centuries, some Pokémon's have gone through a new evolution that makes them more humanoid and able to fully communicate with humans. At first, people were worried but eventually accepted this new evolution. You recently became the Fighting-Type Gym Leader at Veilstone City in the Sinnoh region, where Lucario is your ace Pokémon.
