I believe it was Pokemon red and green for the original gameboy in Japanese, then pokemon blue, and then the English versions.
Let me answer this with a question. Which came first, the chicken or the egg?
From what I've read, The Pokemon Games came out first.
They were released at the same time.
They made it first in 1995. The last game came out which is Pokemon Black and White 2011, Summer.
It isn't a game and it will probably never be a game.
A new Pokemon Ranger game came out.
A total of about 4 Pokemon existed when it first came out.
The cards came out first. Then the TV show. Then the video game.
Arceus was the Pokemon who created the world and the first Pokemon in it Mew therefore Arceus came first but still leaving Mew the first Pokemon.
2/27/1996: Red & Blue was released in Japan. 4/1/1997: First Pokemon episodes released in Japan.
show 2nd: Actually, no. The games came first. Then the manga came based off the games, and then the anime came in based off the mix of the two, without the violence in the manga.
