Not every Pokemon made the cut in Pokemon HeartGold Generations. This guide lists all the non-included Pokemon—those unavailable to catch, evolve, or trade within the game. Whether you’re planning a living Dex, a themed team, or just curious about what’s missing, this list helps you avoid dead ends and focus on what’s truly obtainable in your journey.
Pokemon HeartGold Generations Non-Included Pokemon
Hg-engine is not fully completed, which means a number of pokemon do not have sprites implemented, or their abilities are not implemented. Heartgold can only store 255 abilities anyways, so even if I had added all pokemon, many abilities would have to be culled due to the sheer amount of niche signature abilities.
In the end, I had to make calls on who to cut, so I’m sorry if your favorite didn’t make it!

Final Note
While HeartGold Generations expands on the original experience, a few Pokemon were left behind for balance or design reasons. Knowing which ones aren’t included can save time and guide better team-building decisions. Keep this list handy as you explore—some favorites may need to sit this one out.
