You hatch it just like any egg, keep on walking.However, if you action replay, the code, well idk the cod.
to get rilou go to iron island and a man will follow you through a maze and when you finish he will give you lucarios egg which has rilou in side.walk 500 steps and itll hatch (only if its in you Pokemon team).it cannot be caught in the sinnoh
go to where the 6th gym leader is, there is a boat there, get on it and travel to iron island. Once there, team up with a man called riley and defeat team galactic, after this he'll give you a egg, hatch it, it will be a rilou
6630 steps. By the way, the egg is a Rilou, which evolves into Lucario via happiness.
just go on ur bike to any city and go back and forward for ages
The answer is put Rilou into the poke'walker before you enter and then when you get in put Rilou back into your game.
It can take between 6630 to 6884 steps to hatch a Riolu egg. The number of steps needed will be halved if you have a Pokemon with the ability Flame Body or Magma Armor in your team with the egg.
In order to evolve Rilou you have to become great friends with it.
