After seeing how few some of you have; I really feel like I didn't have a life back in the day. xD
Then again, back then I was friends with Pokemon freaks... so, it's safe to say Pokemon was our life. Haha. I can't remember all of them... but, I can try. I can't even remember which ones were on which games.
R/B/Y
Pigeotto
Gengar
Pikachu (yellow xD)
Raticate (sp?)
Mewtwo
Jigglypuff (never evolved it XD; it was really, really hard but my friend said I couldn't do it without evolving it >>)
Articuno (maybe it was Moltres? [sp?] it was one of the two)
Charizard
Lickitung (I JUST remembered that one xD)
My INFAMOUS Raichu XD
Rapidash
The evolved form of Growlithe... what's it called???
Muk (ugg... another "you can't do it")
Vileplum
Dragonite
And... I think that's it. I might of forgot some. I was big on training when I played the games. My goal was to have all 6 of my favorite Pokemon on each game (every time I played) at Lv 100 before I restarted. Sometimes I made it. Sometimes I got bored and just restarted. Raichu was my favorite. For years, I traded that guy back and forth. He was really my pride and joy. xD It took me forever to get him to Lv 100... but, I succeeded. And I was really proud of myself. I even trusted my friends enough to let them borrow him to cheat and beat the games easier. >> Strangely enough, they always gave him back.
G/S/C
I really can't remember... LOL
I didn't have as many, though. Because, by this point, I wasn't as into the training part of the game as I had been. I was more into the storyline.
