Sorry, I didn't actually have a Jolly Riolu (Naive and Timid were readily available), but mistook your message as saying that you would prefer it, so... yeah sorry.
I'm almost done though, so I'll have you added to my FC and be ready for trade whenever.
EDIT: This is pretty much what Riolu looks like:
IVs: 31-31-31-xx-31-31
Nature: Jolly
Ability: Prankster (Justified on Lucario)
Egg Moves: Crunch/High Jump Kick/Vacuum Wave/Bullet Punch
Gender: Male
