Charmander,
lol, first time i played pokemon blue, i was so ignorant, didnt know i had pokeballs, went through most of the game just with Charizad, which i had before i even fought misty, fainted everything i saw. when charizad was on level 81 i think, i caught my first pokemon XD. ofcourse i used flareon aswell, but only coz i picked up eevee, ended the game with charizad, flareon, and can't remember the others. but since then every generation i pick fire starter and have a flareon, =( except in emerald.
Charmander = Blue
Cyndaquil = silver
Torchic = Emerald
The monkey = Pearl
dont like him, dont use him.
