Eevee Day Celebration!

Eevee Day Celebration! (Japanese: イーブイの日記念！ Eevee Day Celebration!) is a type of limited-time event in Pokémon Masters EX in honor of Eevee Day, a holiday established in Japan in 2018 to celebrate Eevee^[1].

Eevee Tales

This event was focused on various sync pairs formed between player characters and Eevee's evolutions. Variety scouts ran for the duration of the event that allowed players to recruit these sync pairs.

During this event, players could earn event vouchers from battles that could be redeemed in the shop. All battles could be challenged an unlimited number of times except Daily Extreme Battle 1, which could only be challenged once per day. Extra vouchers were automatically exchanged with coins once the event was finished. Players could battle using sync pairs formed with Eevee or its evolutions to earn bonus vouchers.

This event featured a series of Full-Force Battles against Trainers who use Eevee and its evolutions. Similar to the Legendary Arena, players could use multiple teams with a limited number of total sync pairs, with the opponents' health carrying over between rounds and with previously used pairs unable to be used again until the challenge was reset.

First run

The event first ran from November 21 to December 5, 2022, under the name "Three Eevee Tales". It introduced the sync pairs Lyra & Vaporeon, Lucas & Flareon, and Kris & Jolteon.

The "Triple Feature Variety Scout" gave players an increased chance of recruiting Lyra & Vaporeon, Lucas & Flareon, and Kris & Jolteon for the duration of the event.

In this run, the type of voucher that players could earn was the Normal-themed Event Voucher K. The player could battle using Lucas & Flareon, Kris & Jolteon, or Lyra & Vaporeon to obtain +0.6× bonus vouchers; Leaf & Eevee, Sygna Suit Misty & Vaporeon, or Sygna Suit Erika & Leafeon to obtain +0.4× bonus vouchers; and Karen & Umbreon, Valerie & Sylveon, Scottie/Bettie & Pikachu, or Scottie/Bettie & Torchic to obtain +0.2× bonus vouchers.

Additionally, the music that played during the extreme battles was Battle! (Region's Best).

Second run

The event reran from November 21 to December 8, 2023, under the name "Eevee Tales". It introduced the sync pairs Elio & Espeon and Selene & Umbreon. An additional story area was made available after the initial one, which featured these new sync pairs.

The "Double Feature Variety Scout" gave players an increased chance of recruiting Elio & Espeon and Selene & Umbreon for the duration of the event, and the "Triple Feature Variety Scout" gave players an increased chance of recruiting Lyra & Vaporeon, Lucas & Flareon, and Kris & Jolteon for the duration of the event. The "Eevee Day Celebration Tiered Scout", which could only be used with paid Gems, gave players an increased chance of recruiting all five of these pairs.

In this run, the type of voucher that players could earn was the themeless Event Voucher U. The player could battle using Elio & Espeon, Selene & Umbreon, Lucas & Flareon, Kris & Jolteon, or Lyra & Vaporeon to obtain +0.6× bonus vouchers; Elaine & Eevee, Adaman & Leafeon, Irida & Glaceon, Penny & Sylveon, Leaf & Eevee, Sygna Suit Misty & Vaporeon, Sygna Suit Erika & Leafeon, Tina & Flareon, or Rachel & Umbreon to obtain +0.4× bonus vouchers; and Karen & Umbreon, Valerie & Sylveon, Irida & Flareon, Adaman & Vaporeon, Eve & Eevee, Scottie/Bettie & Pikachu, or Scottie/Bettie & Torchic to obtain +0.2× bonus vouchers.

Additionally, the music that played during the extreme battles was changed to a remix of the Pokémon: Let's Go, Pikachu! and Let's Go, Eevee! Trainer battle theme.

Plot

Professor Oak is holding a lecture on Eevee for Trainers who have one as a partner Pokémon. Kris, Lyra, and Lucas attend with their Jolteon, Vaporeon, and Flareon, respectively, to demonstrate some of the ways Eevee can evolve. After the lecture, Professor Oak asks them why they chose to evolve their Eevee the way they did. Lucas and Lyra say that they each evolved their Eevee into the Evolution that matched the type of a teammate they admired, while Kris says that she wanted a fast Pokémon to help her take on other speedy Pokémon she encountered on her journey. Professor Oak then comments that there's always an interesting history behind people and Pokémon.

Elsewhere, the team of Elio and Espeon, the player character and Solgaleo, and Tate and Solrock are battling the team of Selene and Umbreon, Lillie and Lunala, and Liza and Lunatone. Elio's team wins, which Selene hypothesizes could be because they were battling at sunset, so their Pokémon were powered up by the sun. They decide to have another battle when the moon comes out. In the meantime, Lillie asks where Elio and Selene got their Espeon and Umbreon. Selene says that they both met them as Eevee near Paniola Town, and Elio gets nostalgic about the Tauros raised on Paniola Ranch. The sun finally sets, so the teams have another battle, with the Pokémon on Selene's team powered up by the moon.
