You’re standing in the middle of a used game shop, or maybe just staring at a digital listing, and you have to make a choice. It's the classic 2010 dilemma. Do you want the bird that lives in a whirlpool or the bird that lives in a tower? Honestly, back in the day, most of us just picked based on which box art looked cooler. But if you’re trying to build a specific team or fill a Pokedex in 2026, those HeartGold and SoulSilver exclusive Pokemon are going to dictate your entire playthrough.
It’s not just about Lugia and Ho-Oh anymore.
The differences between these two versions run surprisingly deep, touching everything from the common bugs in the grass to the literal gods of the ocean. If you pick HeartGold, you’re getting a very specific flavor of Johto. SoulSilver feels different. It’s subtle at first, but forty hours in, when you’re hunting for a Teddiursa and realize it literally doesn’t exist in your game, you’ll feel the sting.
The Big Hitters: Legendaries and Mascots
Most people think the version exclusives start and end with the cover stars. That's a mistake. While it’s true that Ho-Oh is the "main" legendary for HeartGold and Lugia is the focus of SoulSilver, you can actually get both in either game. The real difference is when you get them and what level they are.
In HeartGold, you face Ho-Oh at level 40 during the main story at the Bell Tower. Lugia is a post-game treat, tucked away at level 70 in the Whirl Islands. SoulSilver flips this script entirely.
But here is where it gets tricky. The "secondary" legendaries are strictly locked. You cannot catch Kyogre in SoulSilver. It is a HeartGold exclusive found at the Embedded Tower after you beat Red. Similarly, Groudon only appears in SoulSilver. To get Rayquaza, you actually need both of them in your party, which means you’re forced to trade regardless of which version you bought.
The Lati Twins and the Kanto Roamers
Once you cross over into Kanto, the version exclusive hunt ramps up. Steven Stone will eventually pop up and tell you about a wandering dragon. In HeartGold, that’s Latias. In SoulSilver, it’s Latios. Catching them is a nightmare because they roam the map like Entei and Raikou, but they are level 35 and have a nasty habit of disappearing the second you breathe.
Wild Encounters: The Johto Staples
The low-level stuff is what usually catches players off guard. You’re wandering Route 32, looking for a Mareep (which luckily is in both), but if you’re hunting for a Growlithe, I hope you bought HeartGold.

HeartGold Exclusives (The Johto & Kanto Mix):
- Mankey and Primeape: Found early on Route 42.
- Growlithe and Arcanine: Absolute staples for a fire-type slot if you didn't pick Cyndaquil.
- Spinarak and Ariados: The bug choice for the early game.
- Gligar: A fan favorite that you’ll find on Route 45.
- Mantyke and Mantine: The kites of the sea.
- Phanpy and Donphan: Heavy hitters usually found near Blackthorn City.
SoulSilver Exclusives (The Heavy Hitters):
- Meowth and Persian: If you want that Pay Day money, you need this version.
- Vulpix and Ninetales: The elegant alternative to Arcanine.
- Ledyba and Ledian: The "other" early-game bug.
- Delibird: Found in the Ice Path, though mostly for the novelty.
- Skarmory: One of the best physical walls in the game, located on Route 45.
- Teddiursa and Ursaring: If you want a massive bear on your team, SoulSilver is the only way.
Basically, the "rivalry" between Growlithe and Vulpix or Phanpy and Teddiursa is what defines the version choice for most casual players. Do you want the dog or the fox? The elephant or the bear?

The Safari Zone and Swarms: A Hidden Layer
The Johto Safari Zone, located west of Cianwood, is a beast of its own. It uses a "Block" system where you place objects to attract certain species. However, even with the blocks, some Pokemon remain much easier to find in one version than the other through the Radio Swarms.
Every day, Professor Oak’s Talk on the Pokegear radio will announce a "swarm." This is how you get non-native Pokemon like Kanagskhan or Yanma. While many of these are shared, the encounter rates for specific "rare" spawns can feel weighted differently depending on your cart. For instance, finding a wild Chansey on Routes 13, 14, and 15 is technically possible in both, but the version exclusives in the surrounding grass might make the hunt feel more cluttered in one version.
What about the Pokewalker?
If you’re a purist playing on original hardware with the pedometer, the Pokewalker routes actually bypass many version restrictions. You can find a Murkrow or a Magby on certain routes regardless of whether you’re playing HeartGold or SoulSilver. It was Game Freak's way of rewarding people for actually walking around.
Making the Final Call
Choosing between these games usually comes down to your preferred aesthetics and your team's needs. If you want a fast, hard-hitting Fire-type like Arcanine and the sheer power of Groudon in the endgame, HeartGold is the play. If you prefer the defensive utility of Skarmory and the versatility of Latios, SoulSilver wins.

Practical Next Steps for Your Playthrough:
- Check your Starter: If you picked Chikorita, you’re going to have a hard time early on. You’ll definitely want a Growlithe (HG) or a Vulpix (SS) to handle the Bug and Steel gyms.
- Plan for the Embedded Tower: Remember that you can't get Rayquaza alone. If you're playing on an emulator, make sure you have a way to "trade" with a secondary save file.
- Use the Pokegear: Check the radio daily. Swarms are the only way to catch certain exclusives that don't appear in the standard tall grass lists.
- The Master Ball Dilemma: Save your Master Ball for the roaming Lati (Latias/Latios). Lugia and Ho-Oh are stationary; you can save your game in front of them and try a hundred times. You can't do that with a dragon that teleports the second the battle starts.
