by trade
Both the game and the TCG have any Pokemon that can use all 17 move types. Go Xerneas. (My opinion)
No. You have to trade from another game.
migrate all your Pokemon except for an egg or a level 1 Pokemon and then start new game with another starter.
You can't catch a starter Pokemon. But to get all of the starters you can trade the Pokemon to another game and restart the game you were playing and get a different starter.
All u have to do is talk to him and he want u to get a coin case
get all the Pokemon on diamondcatch them or trade off another Pokemon game
not possible unless you are willing to trade all your pokemon onto another game and trade them back once you have reset the game...
Maybe Pokemon mystery Dungeon? Or it may be a cheat/hack
You have to trade with friends to get them, or trading with someone else (it can be by using GTS too) or by having another compatible Pokemon game (another LeafGreen, or a FireRed for instance), where you can restart the game and trade the starters.
you get either Pokemon sapphire or ruby and you link and restart the whole game on ruby or sapphire pick out a Pokemon and get to a Pokemon center and link to the other gba and trade for another Pokemon and repeat like twice
First you have need to explore all the place in the game,. After exploring you move forward to the Pokemon league.
you can't you can, but only by trading all your Pokemon to another game before restarting, then trading them back after you have gained the ability to.
