Yo can't catch wild Lucario, but if you go to Iron Island there will be a guy in the cave and he will follow you through the cave until you reach a bunch of Team Galactic Grunts who you will battle. When you've beaten them all, he will thank you a give you an egg. Make sure you have only five pokemon in your party so you can carry it, other wise you'll have to get out of the cave make some room and go through the cave and get the egg. The egg will hatch over time and you'll get a Riolu. When you get Riolu, give him the soothe bell and keep leveling him up and eventually he will evolve into Lucario a Fighting and Steel Type. My Lucario evolved at level 28, but my other one evolved at level 32, so I guess it just depends. Good luck!
