Some Pokémon in Pokémon GO are so hard to find that veteran players have gone years without ever encountering one. While casual players are busy catching Pidgeys and Rattatas, a small group of ultra-rare Pokémon sits at the very top of the difficulty ladder — creatures that require specific events, regional travel, or an almost impossible stroke of luck to obtain.
Whether you’re trying to complete your Pokédex or just curious about what’s genuinely hard to get, understanding which Pokémon are the rarest — and exactly how to catch them — can save you a lot of wasted effort. Here’s what you need to know.
Why Rarity Works Differently in Pokémon GO
Rarity in Pokémon GO isn’t always about how powerful a Pokémon is. Some of the rarest creatures in the game are locked behind specific mechanics that have nothing to do with combat strength. Regional exclusives can only be caught in certain parts of the world. Others only appear during limited-time events that Niantic may not bring back for months — or ever.
There are also Pokémon that technically exist in the game but have such vanishingly low spawn rates that even dedicated players in high-traffic urban areas almost never see them in the wild. A few can only be obtained through research tasks, specific egg hatches, or as rewards tied to particular seasons.
Understanding the category a rare Pokémon falls into is the first step toward actually getting one.
The Rarest Pokémon in Pokémon GO and How to Get Them
Based on general gameplay knowledge and community consensus among long-term Pokémon GO players, the following Pokémon consistently rank among the hardest to obtain in the game. Their rarity stems from a combination of regional locks, event exclusivity, and extremely low encounter rates.
| Pokémon | Primary Reason for Rarity | How to Obtain |
|---|---|---|
| Unown | Extremely low wild spawn rate; letter variants rarely appear | Wild encounters near specific events; event-exclusive research |
| Tirtouga | Rare 7km egg hatch only | Hatch from 7km eggs during specific periods |
| Archen | Rare 7km egg hatch only | Hatch from 7km eggs during specific periods |
| Goomy | Very low wild spawn; event-dependent appearances | Wild encounters during rain weather boost or special events |
| Noibat | Low spawn rate; slow candy accumulation | Wild encounters; 2km eggs |
| Sandile | Limited availability; event-locked appearances | Event-specific spawns and research tasks |
| Axew | Extremely rare wild spawn and egg hatch | 10km eggs; rare wild encounters |
| Deino | Very low spawn rate; limited egg availability | 12km Strange Eggs; rare wild spawns during events |
| Jangmo-o | Event-locked; rarely available outside specific windows | Special research and limited event spawns |
| Carbink | Low base spawn rate | Wild encounters; occasional research tasks |
Regional exclusives add another layer of difficulty entirely. Pokémon locked to specific geographic zones cannot be obtained without either traveling to that region or trading with someone who has.
The Pokémon That Require the Most Effort to Catch
Axew is widely considered one of the hardest non-legendary Pokémon to obtain in the entire game. It can hatch from 10km eggs, but the odds are low, and it appears in the wild so infrequently that many players have never seen one outside of a dedicated event. Getting enough candy to evolve it into Haxorus is a separate challenge altogether.
Deino follows a similar pattern. It’s available from 12km Strange Eggs — which themselves require defeating Team GO Rocket Leaders to obtain — but the hatch rate is low enough that players can go through dozens of eggs without seeing one. Wild Deino spawns are essentially event-only at this point.
Unown holds a special place in the rare Pokémon conversation because it comes in 28 different letter forms, and completing the full alphabet is a long-term project that has occupied serious collectors for years. Individual letters appear near specific real-world events or during Pokémon GO Fest, making a complete Unown collection one of the most impressive flex moves in the game.
Goomy has become more accessible over time but still requires specific weather conditions — rainy weather boosts its spawn rate — or event participation to encounter reliably. Its evolution line into Goodra is powerful enough that demand stays high even when supply is limited.
What Regional Exclusives Mean for Most Players
For players who don’t travel internationally, regional exclusives represent a permanent gap in the Pokédex unless trading is an option. Certain Pokémon are locked to specific continents or even specific countries, and Niantic only occasionally rotates them during global events.
Trading with other players is the most realistic path for most people. Remote trading through friends lists is possible, but ultra-rare and regional Pokémon require high friendship levels and cost significant amounts of Stardust to trade. For the rarest Pokémon, that Stardust cost can run into the hundreds of thousands.
Community events, Pokémon GO Fest, and Safari Zone events have historically offered temporary access to otherwise regional or event-locked Pokémon, making those events particularly valuable for completionists.
How to Improve Your Odds Without Getting Lucky
There are practical steps players can take to increase their chances of encountering rare Pokémon without relying entirely on luck:
- Participate in every Pokémon GO Fest and major seasonal event — rare spawns are almost always elevated during these windows
- Walk eggs consistently, prioritizing 10km and 12km eggs for the highest chance at rare hatches like Axew and Deino
- Build high-friendship levels with as many players as possible to reduce the Stardust cost of trading rare and regional Pokémon
- Use weather boosts strategically — rainy weather increases the spawn rate of Water and Dragon types, which includes several rare Pokémon
- Check community resources like local Discord groups and Pokémon GO subreddits, where players often share real-time sighting locations
- Complete Special Research tasks during events, as these frequently reward rare Pokémon encounters that aren’t available any other way
Patience matters more than almost anything else in this game. Rare Pokémon rotate back into availability more often than players expect — the key is being ready when they do.
Frequently Asked Questions
What is the single rarest Pokémon in Pokémon GO?
Axew and Deino are consistently cited among the rarest non-legendary Pokémon, due to their extremely low hatch rates and near-absent wild spawn rates outside of events.
Can you get regional exclusive Pokémon without traveling?
Yes — trading with other players is the primary method, though it requires high friendship levels and a significant Stardust investment for the rarest regional Pokémon.
Do rare Pokémon ever become easier to catch over time?
Some do. Niantic periodically boosts spawn rates or adds previously rare Pokémon to egg pools and event research tasks, making them temporarily more accessible.
What are Strange Eggs and why do they matter for rare Pokémon?
Strange Eggs are 12km eggs obtained by defeating Team GO Rocket Leaders. They have a chance to hatch rare Pokémon like Deino, making them a key target for collectors.
Does weather affect the chances of finding rare Pokémon?
Yes. Weather boosts increase the spawn rates of Pokémon matching certain types — rainy weather, for example, boosts Dragon and Water types, which includes several hard-to-find species like Goomy.
Is completing the full Unown alphabet actually possible?
It’s possible but extremely difficult. Most letters only appear near specific real-world events or during Pokémon GO Fest, making a complete Unown collection one of the longest-term goals in the game.
