You don't find it, the mans name is Riley, he has a lucario and other rare pokemon. Riley gives you an egg that is rilu.
Riley is a character in Pokemon. He is found in Diamond, Platinum and Pearl versions. http://pokemon.wikia.com/wiki/Riley
he is in the island when u get to canalave city
You find him on iron island in the cave
you get an egg from Riley which hatches then evoles to a Lucio when happy! Riley is in Iron Island in Canavel city :)
In Iron Island. Get there by sailing from canalave city
You have to have the egg with you and walk several thousand steps.
riley is located on iron island if you need help visit youtube and follow marriland or superskamorys walkthruoghs to help you through.
riley gives you an egg and it hatches into riolu it evolves into lucario with friendship you find riley on iron ball island.
The coolest Pokemon in diamond would be Lucario, a fighting and sttel type Pokemon. To get one, you have to help Riley on Iron Island and he will give you a riolu egg. Hatch it and evolve it (by happiness) to get a Lucario.
You don't see it. You have to hatch it from the Egg you received from Riley on Iron Mountain.
