how to evolve eevee into umbreon

To evolve Eevee into Umbreon, you generally need two things: high friendship/happiness with Eevee and a nighttime evolution. Exact steps vary a bit by game, so I’ll cover the main ones.

Core idea (most mainline games)

In most core Pokémon games (like X/Y, Scarlet/Violet, etc.), Umbreon evolution works like this:

  1. Raise Eevee’s friendship/happiness to a high value.
  2. Make sure it does not know a Fairy-type move in games where that matters (e.g., Scarlet/Violet).
  1. Level it up (battle or Rare Candy) at night.
  2. When it tries to evolve, accept the evolution to get Umbreon.

If it evolves with high friendship during the day , you usually get Espeon instead.

How to raise Eevee’s friendship

Common friendship-boosting methods across games:

  • Keep Eevee in your party and walk/run around with it a lot.
  • Win battles with Eevee (avoid letting it faint).
  • Use items that increase happiness, like vitamins and healing items (Potions, etc.).
  • Give it a Soothe Bell if your game has one, to boost friendship gains.
  • In some games, use massages or similar services (e.g., certain NPCs who raise happiness).

In X/Y specifically, once a happiness checker NPC says something like “It looks really happy! It must love you a lot.” you know you’re at or near max friendship; then level up at night to get Umbreon.

Example: Pokémon Scarlet & Violet

For Scarlet/Violet, players commonly report this pattern:

  1. Raise friendship (Soothe Bell, walking, battles without fainting).
  2. Make sure Eevee is at least around level 20+.
  3. Ensure Eevee has no Fairy-type moves (otherwise you may get Sylveon instead).
  1. Level it up at night to trigger Umbreon’s evolution.

If it starts to evolve during the day, or it knows a Fairy move and you get the wrong evolution, cancel the evolution and try again at night after fixing the moveset.

Pokémon GO version (if that’s your game)

In Pokémon GO, the method is different:

  • Set Eevee as your Buddy.
  • Walk 10 km with it as your Buddy, making sure you earn 2 candies with it as Buddy in that time.
  • While it is still your Buddy, evolve it at night to get Umbreon (evolving in the day gives Espeon).

There is also a one-time-only naming trick with specific nicknames for some Eeveelutions, but after using that, the 10 km + Buddy + night method is what players rely on.

Mini story example

Imagine you catch an Eevee early in your adventure and give it a Soothe Bell.
You keep it in your party, let it win easy battles, heal it when needed, and visit a massage NPC once per day.
After a while, the happiness checker tells you it “really loves you,” so you wait until in-game night, feed it a Rare Candy, and watch it glow as it evolves into a sleek, dark Umbreon that’s ready to tank hits for your team.

TL;DR: Max out Eevee’s friendship and evolve it at night (plus “no Fairy moves” in some newer games), or in Pokémon GO, walk 10 km with it as Buddy and evolve at night to get Umbreon.
