Some people say that in the grass section of route 21 you can very rarely find a bulbasuar however I've tried that and it was proven false.They also said that you could find a carmander in Pokemon mansion on cinnabar island and squirtle in seafoam islands these are also false.
P.S. I've tried
Only by trading them from FireRed or LeafGreen.
You need to trade charmander from leafgreen or firered, after you complete what needs to be done in those two games to inable trading between the two.
you can get them by trading with your friend,but i don't think that there will be anyone so foolish to give his/her charmander, squirtle or bulbasaur.You have to choose just one Pokemon in starting and there is no place where you can catch one of these.
You can get Charmander in Pokemon Sapphire by obtaining it in Pokemon FireRed or LeafGreen and trading it to Sapphire. To have Charmander registered in the Sapphire PokeDex, you must defeat the Elite Four. You may have the Charmander before that, but it won't register in the PokeDex.
Unless cheats are used, Charmander can't be caught in Pokemon Diamond. Charmander, however can be obtained with other methods: -Trading with a friend -Transferring it from FireRed or LeafGreen -Obtaining it from Mystery Gift -Obtaining it in either HeartGold or SoulSilver, and then trading it over.
Charizard is the late evolved form of Charmander which is a starter pokemon at the start of Pokemon Firered you can only get this pokemon through the beginning or by trading one from another Firered or even Leafgreen.
you can't find a Charmander, you have to get a Charmander by trading a pokemon to a person that has a Charmander.
There is no way to get Bulbasaur in Platinum without trading or Pal Parking.
generally speaking? trading. just like if you chose charmander you trade for bulbasor and squirtle.
the only way to get charmander in emerald is by trading that's the only way i know
Then you're only hope is trading for a Charmander.
No, other than trading the only way to get a charmander in Pokemon gold is to use a gameshark/other cheat device.
