Quote:
Pokémon Green (ポケットモンスター 緑 ,Poketto Monsutā Midori?, "Pocket Monsters Green"), featuring Venusaur as its mascot, was brought out alongside Red in the initial Japanese release of the games. It never reached other regions; instead being replaced by Pokémon Blue, which was a mail-order-only special edition in Japan.[43]
But it was the first one to be made so that's way it was remade and not blue, but I still since they should of done blue and not green due to green being Japanese release only.
