Introduction
Eevee, the Evolution Pokémon, is a fan favorite in Pokémon GO thanks to its unique ability to evolve into eight different forms—each with its own type and strategic value. Whether you’re a new trainer or a seasoned collector, mastering the methods to obtain every Eeveelution is essential for filling your Pokédex and building a versatile team. This comprehensive guide, updated for 2025, combines the best advice from multiple sources to help you evolve Eevee into all its forms.
For a broader look at the ever-expanding Pokémon roster, check out the total number of Pokémon available in Pokémon GO as of 2025.
The Eeveelutions in Pokémon GO
As of May 2025, Eevee can evolve into the following forms:
- Vaporeon (Water)
- Jolteon (Electric)
- Flareon (Fire)
- Espeon (Psychic)
- Umbreon (Dark)
- Leafeon (Grass)
- Glaceon (Ice)
- Sylveon (Fairy)
Each evolution requires 25 Eevee Candy, but the method for each form varies.
The Nickname Trick: One-Time Guaranteed Evolution
The easiest way to guarantee a specific Eeveelution is by using the nickname trick. This method works once per evolution type per account. Rename your Eevee to the corresponding nickname before evolving:
| Eeveelution | Nickname |
|---|---|
| Vaporeon | Rainer |
| Jolteon | Sparky |
| Flareon | Pyro |
| Espeon | Sakura |
| Umbreon | Tamao |
| Leafeon | Linnea |
| Glaceon | Rea |
| Sylveon | Kira |
How to use the nickname trick:
- Rename your Eevee to the desired nickname.
- Confirm the silhouette of the evolution appears on the evolve button.
- Evolve your Eevee.
Note: This trick only works once per evolution per account. After that, you must use the standard methods.
For more details, see Pokémon GO Hub's nickname trick guide.
Standard Evolution Methods
Vaporeon, Jolteon, and Flareon (Gen 1)
After using the nickname trick, evolving Eevee with 25 candies will randomly result in one of these three forms. There’s no way to control the outcome beyond the one-time nickname trick.
- Random Evolution: 25 Eevee Candy
- Outcome: Vaporeon, Jolteon, or Flareon (each with ~33% chance)
Espeon and Umbreon (Gen 2)
To evolve Eevee into Espeon or Umbreon after using the nickname trick:
- Set Eevee as your Buddy.
- Walk 10 km with Eevee as your buddy (earning at least two candies).
- Evolve during the day for Espeon, or at night for Umbreon.
Tip: Make sure Eevee is still your buddy when you evolve it. The in-game sky will indicate day or night.
For more on the buddy system, see the official Pokémon GO Buddy System Guide.
Leafeon and Glaceon (Gen 4)
After the nickname trick, these evolutions require special Lure Modules:
- Leafeon: Use a Mossy Lure Module at a PokéStop and evolve Eevee while within range.
- Glaceon: Use a Glacial Lure Module at a PokéStop and evolve Eevee while within range.
You can purchase these Lure Modules from the in-game shop or earn them through special research. For more, see Pokémon GO's Lure Module Guide.
Sylveon (Gen 6)
Sylveon requires building a strong friendship:
- Set Eevee as your Buddy.
- Earn 70 Buddy Hearts with that specific Eevee.
- Once you have 70 hearts, the evolve button will display Sylveon’s silhouette.
Pro Tip: Use Poffins to speed up heart-earning. For more on Buddy Hearts, see Pokémon GO Hub's Buddy Adventure Guide.

Special Events and Limited-Time Opportunities
Niantic frequently hosts events that can make evolving Eevee easier or grant exclusive moves. During Community Days, for example, evolution requirements may be reduced, or special moves may be available. Always check the in-game News tab or the official Pokémon GO blog for the latest updates.
Troubleshooting and Final Checks
- Verify the silhouette on the evolve button before evolving—if it’s a question mark, the conditions aren’t met.
- Ensure a strong GPS signal for accurate tracking of walking distance and time of day.
- Restart the app if the correct silhouette doesn’t appear after meeting all requirements.
- Double-check buddy status for Espeon, Umbreon, and Sylveon evolutions.
