Eevee is arguably one of the most popular critters in the Pokemon franchise, becoming somewhat of a secondary mascot behind Pikachu and even starring in its own game. Although Pokemon Let's Go Pikachu and Eevee put this mon in the spotlight, one of the biggest reasons for Eevee's popularity is the fact that it can evolve into one of eight different Eeveelutions, each representing a different type. However, despite the popularity of Eevee and its evolutions, it's unlikely that the Pokemon series will introduce another new Eeveelution in the future, much to the dismay of Eevee fans.
