You can not. you may be able to with gts or with another ds and game, but this method is not good for happiness Pokemon because it requires trading from one game (and ds) to the other.
there is a glitch to get all the starters here is how you do it.
first start a game and get to at least the first Pokemon center you can be anywhere though so no need to restart if you already have a game going. next start a new game picking a starter that you want then go until you have beaten your rival and receive the pokeballs next you catch a Pokemon doesnt matter which. finally you go to a PC and put your starter into the PC switch boxes from box one to box 2 when it is saving turn the gameboy off turn it back on and load your original file check your PC and the starter from the other game should be there you can do this as much as you want. Good luck :) i have only tried this with crystal version so i cant say for sure if it will work on any other version
if u dont have a action replay its impossible the only way to get all three without action replay is trading if u do have a action replay this is the site: http://www.supercheats.com/gameboyadvance/pokemonfireredcodes.htm
You don't.
no sorry
The only way is to trade with someone who has one of the other starters and can trade with firered. I know that leafgreen can and so can another firered
The only way to obtain a Golem is to trade a Graveler. Sorry. :c
First make sure that when you start your game that you save before you get your Pokemon then get it trade your starter away then turn off your game system then when you turn it back on pick a different starter then repeat until you have all of them or more. Note:Does not work with Pokemon leafgreen or firered because you must get to far in the game so don't try that.
You can not get slowbro in fire red at all.
no sorry
It is not possible to get all three starters in Pokemon LeafGreen without trading. This was an intended mechanic to encourage interaction between players.
No, you can only get all starters without trading in Pokemon yellow, but Leaf Green is a newer version of Pokemon green, so it's impossible.
The only way is to trade with someone who has one of the other starters and can trade with firered. I know that leafgreen can and so can another firered
That's impossible.
NO,you will have to trade it to evolve it.
you can't.you must trade

cheats
You can't. You only get one without trading it from another Pokemon game.
Not possible unless you use a cheating device.
Celebi cannot be obtained in Pokemon FireRed or LeafGreen legitimately without trading. There are no events for Celebi currently and an GameShark may be required.
