With eight official Eeveelutions, fans of the beloved normal-type Pokémon aren't hurting for options — yet paradoxically, they're also one of the most neglected segments of the fandom. After all, it's been 13 years since Game Freak introduced a new Eevee monster in Pokémon X and Pokémon Y. With 18 standard Pokémon types in the games, that means we haven't seen even half of the possible Eeveelution concepts. Never mind the number of Eeveelutions that would be possible if Pokémon's developers ever started combining Eeveelution types.
