It finishes when you have defeated the Pokemon League and the Mysterious Dungeon which contains MEWTWO which you can catch and that'll be the end of the game pretty much except I'm sure you can catch Pokemon like Mew.
HOPE THIS HELPS
Trade, Train, Evolve, Catch, Breed all the pokemon!
step1:..... go to the ummmm cereulean tonnel do it then finish look on your map lol
You can't.
You need the rainbow pass to get there. That means you must help Celio finish his machine.
All starters, including Bulbasaur, can't be caught in Pokemon LeafGreen.
Trade, Train, Evolve, Catch, Breed all the pokemon!
No but it is essential to trading with other games.
You cannot 'finish' Pokemon LeafGreen and FireRed. You might be thinking about defeating the Elite Four. That is the end point of most trainers, but you can go ahead and capture legendary Pokemon like Mewtwo, Lugia and so-on.
To get Suicune you need to had chosen Charmender for your Starter Pokemon .Then finish the Elite Four .And
You can only get inside when you fight finish the Pokemon league .
you have to trade all of the hoenn-exclusive Pokemon from a Pokemon ruby/sapphire/emerald cartridge
...? umm this question doesnt make sense. you do it by seeing Pokemon! all the Pokemon in the game! (no trade)
You must defeat the elite four and the Pokemon champion then catch all the Pokemon which is only possible with help from friends.
start with bulbasaur an finish the game (includeing n dex) and done
finish the pokedex Dee Dee Dee celebrate! level it up
If you finish the puzzle you can catch the Pokemon unown in the tanoby chambers.
Many people think that after you beat the Pokemon league and your rival, you completed the game. To finish the game totally, get every Pokemon in the kanto and national pokedex and beat the Pokemon league. It's a real challenge!
