"Veevee" was introduced with the Japanese name of the Eon Mail (Japanese: ブイブイメール Veevee Mail) in Generation II. The term was first used in English as the name of Y's Eevee in the Pokémon Adventures manga. In the core series, the first English usage was for the move Veevee Volley in Pokémon: Let's Go, Pikachu! and Let's Go, Eevee!. In the Battle Tower from Pokémon Sword and Shield, Poké Kid Alex, who is dressed as an Eevee, mentions her "Veevee power".[8] In Pokémon Scarlet and Violet and Pokémon Masters EX, Penny affectionately uses the term "Veevees" to refer to her team of six Eeveelutions.

She is very correct to refer to her team of Veevees like that
