In my opinion, they are are Eevees (Pansage, Panpur, and Pansear) and when they evolve they become like Leafeon, Vaporeon, and Flareon (Yanakki, Hiyakki, and Baokki respectively) Since Eevee wasn't comming along for this Generation, they where made for Grass, Water, Fire coverage. (Keep in mind, I am exculding the other Eeveelutions for this summary.
