Gen 1-Gen 9

I am trying to play through every main line game and bring my team through each generation of games. I'm pretty sure I have everything I need, im using a molded 3ds to be able to transfer everything up into home.

I need 6 underutilized pokemon per gen and I want you guys to pick them. I have both versions of each game so version exclusives shouldn't matter. You can pick the pokemon and there names. You can pick starters aswell (as long as it's not chikorita)
