Rilou Evolves Into Lucario At Level Thirty With Happyniess PEACE,OUT!!
You can have an egg with a ditto at the Pokemon daycare center with your riolu and evolve that Pokemon into a Lucario.
Riolu is a fourth generation baby Pokemon. It will evolve into Lucario when its happiness is maxed and it is leveled up during the day.

Lucario
In order to evolve Rilou you have to become great friends with it.
You can't, Lucario isn't included in Red/Blue Rescue Team. There are only mentions of him, and that's about it. ^^^^^^^^^^^^^Actually you can because, i have done it and what you have to do is get a Nintendo cheat system its the only 1 that does is and get a rilou and evolve into Lucario and there you have hope i helped :)
you cant. on iron island team up with riley till you get to the end of the cave then he'll give you a rilou egg.when the egg haches level him up. "friendship evolve". or if you have a exp share you can give it to rilou "make sure rilou is in your pary" get one of you strongest Pokemon and battle Pokemon that it's level are higher than rilou and he will get some points and rilou's level goes up . hope this helped.
Lucario will not evolve.
Riolu evolves into lucario and lucario doesn't evolve.
level it up to 30-50th level. ANd yr rilou is spelled wrongly, it is riolu.
Well, to be honest, it can evolve once its happy enough.Yep this is one of those evolutions that can evolve at anytime. Mine evolved at level 56 or 59. It was level 36 when I transferred it from Pokemon pearl onto my Pokemon white game. I'm nine and I beat the entire game in a week with the help of my Lucario.
