lucario is a pokemon (no he's not stupid just because he's from pokemon), but to tell you the trueth i've never seen him in an ep before....u know....not that i watch or anything. he's able to use his own aura as a power sorce, and his aura gets strong as he gets weaker ( it dident make sense to me ether, so i'll explain), as he get beaten up more, his aura gets stronger, therefor, he gets more power, so he gets stronger, and he can read minds and tell people's feelings just by there arua. the only way i know this guy, is from super smash bros brawl ( witch is one of the best games ever), and obviosly, i kick ass with lucario.
