(well first let me tell you this don,t trade Riolu because if you get him back or not he or she will not evolve)but anyway Riolu evolve at Lv.16 or 24
A Riolu, which can evolve into a Lucario.
you get a riolu which can evolve into lucario
from Riley he gives you a Riolu egg and you can evolve it at high friendship
You must raise Riolu's happiness to the maximum then level it in order for it to evolve into Lucario.
No, but Lucario can.
No Lucario does not evolve in any version of Pokemon. Lucario is the fully evolved form of its preceding evolution, Riolu.
Go to iron island and help this dude called riley and he will give you an egg which contains riolu and give the riolu happiness and it will evolve into a lucario.
IN POKEMON PLATINUM, MY LUCARIO HAD TO WAIT UNTIL LEVEL 37 TO LEARN AURA SPHERE. YOU MAY BE ABLE TO LEARN IT EARLIER IF YOU WAIT TO EVOLVE YOUR RIOLU =)
You can have an egg with a ditto at the Pokemon daycare center with your riolu and evolve that Pokemon into a Lucario.
lucario evolves at level 26
Riolu evolves into lucario and lucario doesn't evolve.
no
