In the video games In the
Red,
Blue,
Yellow versions, the player receives one Eevee in Celadon City. In
Pokémon Yellow, the player was to receive an Eevee from
Professor Oak at the beginning of the game as the player's starter. However, the player's rival decides to take the Eevee before the player can obtain it. Due to this, the player is forced to choose the wild
Pikachu that Professor Oak had caught earlier as a starter. The player's rival meanwhile evolves his Eevee into any of the three evolutions available, depending on the outcomes of the player's encounters with him in the early parts of the game. Eevee went on to reappear in nearly every subsequent installment of the main series. In
Pokémon Sun and Moon, Eevee gained the ability to use a special "Z-Crystal" item known as Eevium Z. This allowed it to use a special "Z-Move," a one time use powerful attack, known as Extreme Evoboost. In
Pokémon Sword and Shield, Eevee gained the ability to use a unique "Gigantamax Form," which could be used when Eevee utilized the game's "Dynamax" mechanic, which exponentially increased the Pokémon's size and changed its appearance. The transformation allowed it access to a unique attack known as G-Max Cuddle, which deals damage and infatuates opponents of the opposite gender. In 2018, remakes of
Pokémon Yellow, ''Pokémon: Let's Go, Eevee! and Pokémon: Let's Go, Pikachu! were released. Unlike in the original Pokémon Yellow
game in which Pikachu was the only Pokémon able to walk around with the player outside its Pokéball, in Let's Go, Eevee!'' the player's partner and starter Pokémon Eevee refuses a Pokéball and stays with the player in the overworld. The partner Eevee is able to wear accessories and clothes and "hairstyles" which are visible in the overworld. Like Pikachu, in ''Let's Go, Eevee!'', the partner Eevee refuses to evolve, but is able to learn special moves not available in other games, with eight possible moves each based on one of Eevee's evolutions. Game developer
Junichi Masuda said that Eevee was chosen for the remake because of its popularity in
fan art, although
Psyduck was also considered before it was decided its coloring was too similar to Pikachu. Outside of the main series, Eevee has appeared in a variety of spin-offs. In
Pokémon Stadium 2, Eevee stars in its own minigame called "Eager Eevee". Players have to run around in circles while Aipom raises and lowers a cover on berries. The object is to be among the first to grab some of the berries. It also appeared in a variety of other games, such as the
Pokémon Mystery Dungeon series,
Pokémon Conquest,
Pokémon Go,
Pokémon Unite and
New Pokémon Snap. It also acts as the first Pokémon available to the player in
Conquest, and also does so in
Pokémon XD: Gale of Darkness.
In other media In the
anime, Eevee first appeared in
The Battling Eevee Brothers. A little boy named Mikey was hiding the Evolution Pokémon from his three older brothers because they wanted him to evolve it. However, when Mikey's Eevee single-handedly defeated
Team Rocket, they were able to accept the fact that Mikey wanted to keep his Eevee just the way it is. Ash's longtime rival
Gary Oak uses an Eevee that eventually evolves into
Umbreon. The Kimono Girls who first appeared in the
Pokémon Gold and Silver games, later make an appearance with their Eeveelutions. The youngest of the Kimono girls had an unevolved Eevee, though it evolved into an Espeon later on in the series.
May has an Eevee that hatched from an Egg, which she used in Pokémon Contests all across the Kanto region. When May traveled to
Sinnoh, it evolved into
Glaceon. Later in the anime, another Eevee owned by the character Chloe Cerize is shown to be incapable of evolving. While the reason is unknown, the other characters theorize it is due to indecisiveness on what to evolve into. In
Pokémon Adventures,
Red is in possession of an Eevee which had been experimented on by
Team Rocket. As a result, it could transform back and forth from the three evolutions
Vaporeon,
Jolteon, and
Flareon along with its base form, allowing it greater tactical ability in fighting other Pokémon. Eventually, it evolved into an
Espeon, losing its special ability to interchange abilities. Eevee and its evolutions have appeared in the
Pokémon Trading Card Game. It has also appeared in
Animal Crossing: Pocket Camp and the
Super Smash Bros. series. ==Promotion and reception==
