>>53937397There is a pattern but theres more than one, Vaporeon/Jolteon/Flareon are Showers/Thunders/Booster Espeon and Umbreon are Elfie and Blackie, Leafeon and Glaceon are Leafia and Glacia, and Sylveon continuted their name pattern with Nymphia. So its all english words with various suffixes, and with the exception of Slyveon they share the suffix with the Pokemon they were introduced with. Booster kinda screws it up because he doesn't have an "s" at the end, not sure why they wouldn't just call him Boosters.
