any level you just need to beat magma boss 4. TRUST ME IT TOOK ME UNTIL LEVEL 79 TO FIGURE IT OUT. IT JUST EVOLVED.
You must raise Riolu's happiness to the maximum then level it in order for it to evolve into Lucario.
Make sure your Riolu is happy. When it is happy level it up and it will evolve into a Lucario!!!
Riolu evolves into Lucario at level 14. (But if evolution is skipped, it will try to evolve at every level up after that as well.)
Riolu evolves when it is at max happiness. After that, level it. Then you will have a Lucario.
Riolu evolves into lucario and lucario doesn't evolve.
You make riolu have max happiness and then level it up
lucario evolves at level 26
he evolves into lucario at level 45 and up.
At this point in time, Lucario is its final form. It does evolve from riolu.
(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
Riolu will envolve when riolu's level has reached to the required level. to level him up battle people or battle wild Pokemon
You must first evolve it to Lucario, then level it up.
