If you don't have it in Leaf green or Fire Red trade one.And if you don't you can't get one!
You need pokemon emerald. once you compete the hoenn dex(see all 200/202 pokemon) then prof. oak will call you on your poke'nav and say he has a surprise for you. you go to his lab and you can choose, totodile, cyndaquil or chikorita, this is the only way besides hacking and cheating or trading with someone who has done that, to get the gold & silver(johto) starters.
