Welcome to the club AlexOzzyCake! Lucario tends to be on everyones mind after watching Lucario and the Mystery of Mew.
To answer my own topic:
If you could have Lucario, Riolu, or both star in any video game of your choice, what would it be and why?
I still can't think of any game that would be perfect for Lucario or Riolu to star in, but I did think of a random Digimon x Pokemon or Pokemon x Digimon crossover game. I know it doesn't exist, but if it did, I would love to have Lucario star in the Pokemon x Digimon game. I would not mind Lucario also being a character in the SoulCalibur series, just because he seems appropriate in fighting games. I would suggest an RPG, but I can't think of any that would make sense other than the crossover idea I mentioned.
