Can you evolve Kanto Pokemon into Non-Kanto Pokemon?
Yes, you can evolve Kanto Pokemon such as Chansey into Non-Kanto Pokemon such as Blissey when you reach the new Islands at the end of the game. This includes Chansey, Golbat, and all the RBY Pokemon that evolved through trades with attached items. However, Eevee will not evolve through happiness into Umbreon or Espeon as Fire Red and Leaf Green do not use a clock system. You need to trade Eevee to Ruby, Sapphire, Emerald or Pokemon XD to evolve it.
