Yes, because it is more powerful when it evolves into a Lucario than just staying a Riolu.
You gotta have high friendship at day time ;)
No Lucario does not evolve in any version of Pokemon. Lucario is the fully evolved form of its preceding evolution, Riolu.
Riolu will envolve when riolu's level has reached to the required level. to level him up battle people or battle wild Pokemon
you can not evolve a riolu if its level100 I'm sorry
it evolves by care, happiness you better not let it faint. it can evolve at lvl 2-99 most riolu evolve at 30-40. GOOD LUCK! HOPE I HELPED ;)
Riolu evolves through friends ship evoution between 4:00 am and 8:00pm.
there isn't really a level, it elvoles when it reaches max freindship
Catch a Riolu and evolve Riolu.
Riolu is a Fighting type pokemon.
