Eevee positions itself as one of the most popular Pokémon in the franchise due to its plethora of unique and colorful evolutions. Eevee’s evolutionary path can depend on its environment, encounters, and relationship with its trainer.
For players looking to evolve their Eevee into an Umbreon – the Dark-type evolution – in Pokémon GO, there are three ways to do accomplish this.
To evolve an Eevee in the first place, you need to feed it 25 Eevee candy, which can be obtained by catching or transferring Eevee. Once you’ve collected enough Eevee candy to evolve your Eevee, you can leave it to chance and see what Eevee will randomly evolve into.
However, if you want to guarantee your Eevee evolves into Umbreon in Pokémon GO, there are two other methods you can use to guarantee it.
How to use the Buddy System to evolve Eevee into Umbreon
Pokemon GO’s Buddy system allows players to have one of their Pokemon follow their trainer character around on the map, which provides beneficial interactions and mechanics with that Pokemon. Normally, Eevee evolves into Umbreon after achieving a strong friendship with its trainer, so making an Eevee your buddy in Pokemon GO is a surefire way to evolve it into an Umbreon.
Unlike other Pokemon who evolve using the Buddy mechanic, Umbreon does not require its trainer to accumulate hearts. Walk 10 kilometers with Eevee as your buddy and evolve the Eevee at night to obtain Umbreon.
How to evolve Umbreon in Pokemon GO using a Nickname
Each potential evolutionary path for Eevee has a nickname that will immediately evolve your Eevee into the associated evolution. Change the nickname of the Eevee that you’d like to evolve to “Tamao,” then evolve it for a guaranteed Umbreon. One thing to keep in mind that this method can only works once per player for each of Eevee’s evolutions.
