Our Pokemon Blue, is Japan's Pocket Monsters Green. Our Pokemon Red, is Japan's Pocket Monsters Red. Our Pokemon Yellow, is Japan's Pocket Monsters Pikachu. Meaning, that Japan's Pocket Monsters Blue, has no American equivalent, correct?
So, let me get this straight. I've technically been playing Pokemon Green ALL THESE YEARS, and never knew it? --- My Systems: Turbografx-16; NES; SNES; Sega Genesis (Model 2); Genmobile; N64; Gamecube; Wii; GB; GBC; GBA; GBA SP; DS Lite; DSi; PSX; PS1; PS2; PS3
American Red and Blue are sort of a hybrid of Japanese Red, Green, and Blue. They use the Pokemon graphics and code from Blue, but their Pokemon locations are the ones from Red and Green. That is what caused one of the mistakes in American Red and Blue: the one where a guy says that the Raichu (which was a Graveler in Japanese Blue) you traded him evolved. That's because they used the Pokemon from Red/Green but translated the text from Blue.
