>>39894169Jap fans hated that design and called him "Fire". Even the Pocket Monsters manga made fun of the change.
>>39893296Color names originally came from PokeSpe and got retxonned into games after GSC came out.
JapPokespe had the cut girl character present as "Blue". Gary was "Green", since that was the main companion game to Pokemon Red in Japan.
American "Pokemon Adventures" translated the girl as "Green", since Gary was "Blue" (the main companion game to Pokemon Red in the US), and the Green game was absent.
"Leaf" was the name used for her new design after LeafGreen came out. They went back to the color name (dependent on language) in LGPE, but she'll apparently be Leaf again in Masters.
