Eevee is a Normal-type Pokémon introduced in Generation I. It evolves into one of eight different Pokémon through various methods. Eevee has a Gigantamax form.
It is the game mascot and starter Pokémon in Pokémon: Let's Go, Eevee!, as well as for the main characters of Pokémon XD: Gale of Darkness and Pokémon Conquest. It is the starting Pokémon and first Pokémon employee of the player in Pokémon Café Mix. It is also the rival's starter Pokémon in Pokémon Yellow, although Professor Oak originally intended to give it to the player.
In Pokémon: Let's Go, Eevee!, the player starts with a special Eevee known as a Partner Eevee. The Partner Eevee has purple eyes and a lighter shade of fur. These design elements were likely taken from the anime, which implemented similar traits starting in Pokémon the Series: Ruby and Sapphire. Partner Eevee has higher base stats and access to moves that normal Eevee do not. Partner Eevee is the only Pokémon capable of performing Bouncy Bubble, Buzzy Buzz, Sizzly Slide, Glitzy Glow, Baddy Bad, Sappy Seed, Freezy Frost, Sparkly Swirl, and the Partner Power, Veevee Volley. The marking on the tip of a female Partner Eevee's tail is heart-shaped. Before Pokémon Sword and Shield, this trait was unique and wasn't found on other female Eevee. In Pokémon Sword and Shield and later Pokémon GO updates, the unique tail pattern is present on all female Eevee as a true gender difference.
