This may seem like an odd topic but I recently found my old Game Boy Color, but cannot find my old Red version anywhere. My girlfriend found an old Gold version for me to use but I have never played gold or silver, have no idea which pokemon to use, or to try and collect in order to beat the game's gyms. Any advice on which pokemon to use or any other strategies would be most helpful 
UPDATE: I went with Cyndaquil which seemed to be the majority's choice. It is freakin' awesome! May not look as cool as the original fire type starter charmander but coupled with a level 13 Pidgey, my level 14 evolved Cyndaquil (can't remember evolved name) has blitzed through the first gym and "bellsprout tower". Now I just need a pokemon capable of flash to get through the cave; HELP!
