#I could go on FOREVER about eeveelution variations

[indepthpokemonheadcanons]

Eeveeution morphs are way more diverse than what we see! The specifics of eevee's environment and experience are hugely important to its final appearance. A Flareon that's been exposed to a volcano is going to look a lot different than a Flareon that's only been exposed to camp fires!

Completely agree with this. Vaporeon sees some of the most variation - freshwater vaporeons and saltwater ones differ quite considerably. Arctic vaporeons are known for their thick layers of blubber, while the ones found in warmer oceans are small and lithe and spend very little time on land. Trainers favour lake and riverside vaporeons the most, as they hunt both in and out of water and have the most versatility on the battlefield.
