At first, I never got around hatching the egg. I figured it cool later on, so on my training-for-elite-four run, I decided to give the egg a little piggyback. It took sooo long to hatch IMO.
Then I was like, cool. A Riolu. Obviously evolving into that ever-so-awesome-god Lucario who everyone talks about. I thought, what the heck. I trained it to level 8, and it evolved into Lucario. Nice. End of story, you go to PC now. And I forgot about it.
Later on I was like what the shizz Lucario is this awesome? Amazing stats! And so from then on I make it a point to consider using it.
