From Bulbapedia, the community-driven Pokémon encyclopedia.
Hey, I'm Dex. I've played each generation of Pokémon other than the third one, though I will probably get it at some point in time. I don't like all the competative battling stuff, so I just play through the stories of each game and then store the Pokémon that I used in that story in the Stadiums or Battle Revolution for Diamond. This way I can always look back and see the Pokémon that I used and even battle with them some more outside of the Game Boy games.
