I need every single one except easily caught one's from Platinum, so here we go:
Bulbasaur
Charmander
Squirtle
Caterpie
Weedle
Paras
Meowth
Growlithe
Farfetch'd
Seel
Drowzee
Krabby
Exeggcute
Cubone
Tangela
Kangaskhan
Jynx
Pinsir
Lapras
Omanyte
Kabuto
Aerodactyl
Snorlax
Dratini
Mewtwo
Evolutions of any of these Pokemon are fine, because I'll just breed them.
