trade or hack i think?^^
Chikorita, Totodile, Cyndaquil.
The only way to get the Johto starters in FireRed and LeafGreen is to obtain them in Colosseum (Mt. Battle 1-100 Challenge) and trade them to the Gen III games Ruby/Sapphire/Emerald. I am unsure if FR/LG can communicate with Colo. directly.
you go back to professor oaks lab and he gives you the choice of either cyndaquil chikorita and totodile
You can't. You can get Cyndaquil in XD or Colloseum (one of those 2), and Emerald (only if you completed the Hoenn Dex; can choose between Cyndaquil, Totodile and Chikorita)
FireRed And Leafgreen: Squirtle,Charmander, BulbasaurRuby Saphire and emarald: Mudkip, Torchic, TreekoDiamond, Pearl, and Platinum: Piplup, Chimchar, TurtwigHeart Gold, Soul Silver: Totodile, Cyndaquil, Chikorita
You need to complete the kanto pokedex, after this Prof. Oak give you one of this pokemon's: Chikorita, Totodile (evolves into croconaw) or Cyndaquil.
You cant.
Transfer the Pokemon from FireRed or LeafGreen, after you have beaten the Elite Four in it, or you can get some from the expanded area of the Safari Zone and catch some, but not all of the Johto Pokemon. To get one of the three starters, Chikorita, Totodile or Cyndaquil, you have to complete the Hoenn pokedex.
You can get Totodile In Pokemon FireRed(Johto Starters).In GBC You cant get IN Pokemon Gold,Silver,Crystal.Not sure if in Ruby,Sapphire Emerald.
The starter Pokémon for HG and SS will be the same as they were in Gold/Silver/Crystal - Cyndaquil (fire), Totodile (water) and Chikorita (grass). HeartGold and SoulSilver are remakes; not reinventions of the same regions, just like with LeafGreen and FireRed; the Pokémon are all the same, just with updated versions.
First Gen: Bulbasaur, Charmander, or Squirtle (or Pikachu in Pokemon Yellow) Second Gen: Chikorita, Cyndaquil, or Totodile Third Gen: Treecko, Torchic, or Mudkip (or Bulbasaur, Charmander, or Squirtle in the FireRed and LeafGreen remakes)
To get a Totodile in FireRed you must trade it over from Emerald version. To get the Totodile in Emerald you must first complete the Hoenn PokeDex and you will be given a choice of three Pokemon: Totodile, Cindiquil and Chikorita.
