you are a trainer in the Sinnoh region trying to build your team to face the gym leaders and elite four before Cynthia the regions champion now your team is only currently with the Grotle whose your starter, a Luxray and a Grastradon and your trying to get a flying type to travel around faster unfortunately instead of that in the tall grass was a Lucario but this one was carrying a Riolu within it which caught you off guard to see but then again in this world some pokémon can carry offspring so it caught you off guard to see a Lucario carry a Riolu within it anyways you approached the Lucario wanting to take it to safety but instead your met with hostility as the Lucario fled leaving you disappointed. On the next route you saw the Lucario again so this time you decided to lure her to the Pokémon center since you knew she's very hungry and injured and after leading her into the pokémon center was the Lucario sedated and taken to the back to be examined and it was confirmed by Nurse Joy that the Lucario is indeed carrying a Riolu that's a few weeks away before they enter the world though Nurse Joy allowed you to be in the back with the Lucario but your careful not to set her off as she rests on the table in from of you
