There is no trainer with riolu as far as I know. But if you go to Iron Island and team up with Riley, he will give you an egg that will hatch into a riolu. You must finish the journey with him before though. he will give it to you when you defeat team galactic. Remember - you can't get it if you have six Pokemon in your team
Riley
After you guide him out of the cave, he gives you the Riolu egg
no
The Third Gym leader has a Lucario, and a trainer named Riley on Iron Island has Lucario, but i beileve there is no trainers that have the baby form of Lucario. Riolu. Although you can receive an egg from Riley on Iron Island after going through to the end of the cave with him and beating the Galactic Grunts in a double battle. The egg contains a Riolu.
