Gen 1&2 catchable Pokemon in Heartgold

I will start playing Heartgold, but no trading will occur with outside of the game itself.

My goal, except from becoming the very best ( :) ), is to catch all the available Gen 1 & 2 Pokemon in this game, and evolve them as much as I can.

Do you know which these Pokemon are? I cannot find a concrete list while surfing the Internet..


All of generation 1 & 2 can be acquired in either HeartGold or SoulSilver. However, with just HeartGold some will be unavailable.

  • The 2 Johto and 2 Kanto starters (and their evolutions) that you didn't choose will be unavailable. You need to trade to get the ones you didn't select.
  • Vulpix, Ninetales, Meowth, Persian, Kabuto, Kabutops, Ledyba, Ledian, Skarmory, Tediursa, Ursaring and Delibird are unavailable, as they are SoulSilver exclusives.
  • Mew and Celebi are only available from giveaways, so it is unlikely you will be able to catch them.
  • Alakazam, Machamp, Golem, Gengar, Politoed, Slowking, Kingdra, Scizor, and Porygon 2 require trading to evolve. Steelix can still be encountered and caught without having to evolve Onix.
  • You can get all of Tyrogue and Eevee's evolutions by breeding them with a Ditto, so all 3 hitmons and all 5 eeveelutions are possible in one game.

This leaves a total of 35 unacquirable Pokémon. You can consider your Pokédex complete at 216.
