Quick Answer: To evolve Eevee into Umbreon in Pokémon GO, you must first evolve Eevee at night while it is set as your buddy Pokémon and you have walked at least 10 kilometers with it. Alternatively, you can rename your Eevee to 'Tamao' before evolving it, but this method only works once per account.

Key Facts

Overview

Eevee is a unique Pokémon known for its remarkable ability to evolve into multiple different forms, often referred to as 'Eeveelutions'. Among these, Umbreon stands out as a powerful Dark-type Pokémon, celebrated for its defensive capabilities. Evolving Eevee into Umbreon requires specific conditions to be met, ensuring that trainers strategically plan their evolution process. This guide will detail the methods for obtaining Umbreon, focusing on the popular mobile game, Pokémon GO.

Understanding Eevee and Umbreon

Eevee, the 'Evolution Pokémon', possesses unstable genetic material that allows it to adapt to its environment and evolve into various forms. Its evolutions are influenced by factors such as friendship levels, evolutionary stones, time of day, and even specific moves learned. Umbreon, its Dark-type evolution, was first introduced in Generation II of the Pokémon franchise and is known for its sleek, dark fur adorned with golden rings that glow. In Pokémon GO, Umbreon's stats lean towards defense, making it a valuable asset in gym battles and trainer duels.

Method 1: The Buddy Walk and Night Evolution

This is the most reliable and repeatable method for evolving Eevee into Umbreon in Pokémon GO. It requires patience and a bit of walking, but it guarantees the desired outcome without relying on a one-time trick.

Step 1: Set Eevee as Your Buddy
First, select the Eevee you wish to evolve and make it your active buddy Pokémon. You can do this from the buddy screen in your trainer profile.

Step 2: Walk 10 Kilometers with Eevee
You need to walk a significant distance with your Eevee buddy. The requirement is to walk at least 10 kilometers. As you walk, Eevee will earn candy. You must earn at least 2 Eevee candies through walking for this method to work. Keep track of your progress in the buddy screen; it shows how far you've walked with your current buddy.

Step 3: Evolve Eevee at Night
Once you have met the walking and candy requirements, the crucial final step is to evolve Eevee during nighttime hours within the game. The game's day/night cycle is synchronized with your real-world location's time. Ensure that the in-game sky appears dark, indicating nighttime. Evolve your Eevee buddy while it is still set as your buddy and the in-game time is night. A silhouette of Umbreon should appear on the evolve button, confirming the evolution will result in Umbreon.

Method 2: The Nickname Trick (One-Time Use)

Pokémon GO developers have implemented a nickname trick that allows players to guarantee specific Eeveelutions. For Umbreon, the designated nickname is 'Tamao'.

Step 1: Rename Your Eevee
Select the Eevee you want to evolve and rename it to 'Tamao'. Ensure the spelling is exact, including capitalization.

Step 2: Evolve Eevee
After renaming, simply tap the evolve button. If done correctly, your Eevee will evolve into Umbreon. The cost remains the standard 25 Eevee candies.

Whether you choose the reliable buddy walk method or utilize the one-time nickname trick, both paths lead to acquiring this formidable Dark-type Pokémon. Remember to check the in-game time and buddy status carefully to ensure a successful evolution.
