Screameon

About a quarter of the way through Day 1, the chat decided to try to obtain a Leafeon for the party, as they'd already used each of the other 7 Eeveelutions on at least one final team and the trigger for its location-based evolution was early in the game. With that goal, they deposited everyone but their starter in the PC. With only one empty spot remaining in the party, they captured a male Eevee, and an hour and a half later, he became the first Pokémon of the run to evolve but not into a Leafeon.
