Pridefull, but sometimes stuborn
Lucario is pretty prideful. He can sometimes be stuborn. He's willing to sacrifice himself to keep a friend safe.
He has no equipment. Though the two spikes on the top of his wrists turn into 3 white claws.
A 11 year old girl named Samantha found Lucario as an egg outside the castle she lived in. The girl she lived with would not allow her to keep the egg, though she kept it anyway. When he hatched as a Riolu the girl Samantha lived with found out she kept the egg, and Smantha's gaurdian was going to kill Riolu[Lucario] So Samantha and Riolu[Lucario] ran away into the forest. And they lived their.
When Riolu[Lucario] evolved into Lucario, Lucario trained her in pysical fighting, and Samantha taught Lucario how to cook and heal people. One dark stormy night, they where outside training, a Black Dragon came out of the clouds and attacked them. Lucario let is gaurd down for one second and was knocked out. The ragon killed Samantha.
Lucario traveled around, alone and depressed ever since.
