Only emerald can get a johto starter however you can trade the johto shadow Pokemon from Pokemon colosseum then breed them in sapphire to get the johto starters you can also trade the johto starters directly from Pokemon xd gale of darkness.
No way you can't get a johto starter Pokemon in Pokemon leafgreen. The only way is to trade with someone to get it.
Cyndaquil, Chikorita, Totodile
The only 2 ways to get johto starters is to see all Pokemon in emerald, and beat mt.battle in Pokemon XD and then send them to ur gameboy adv.
Obtain 200 Pokemon in Pokemon ruby, sapphire or emerald, then go to professor birch and you get to choose one of the johto starters, then you migrate the starter you chose to Pokemon, diamond, pearl, or platinum.
you get them by catching all 200 Pokemon
You can never find the starters in the wild you can though find johto pokemon.
no you cant unless you have an action replay to catch trainers Pokemon but other then that you cant catch johto starters in the wild
catch....... BUT ONLY on emerald
not originally, but if you migrate them then yes.
The Johto starters, Tododile the Water Pokemon, Chikorita the Grass Pokemon, and Cyndaquil the Fire Pokemon
You can only get the Johto starters by trading from Emerald or XD.
