The best team to beat elite 4 in Pokemon FireRed and leafgreen are the first six Pokemon you caught and trained
get some good pokemon with good move
not realy get diffrent types in leaf green to beat the elite four
Any Pokemon really, you just need a good strategy. Watch out for Pokemon type advantages though.
first you need your starter Pokemon be a squirtle. Then you have to beat elite 4. Then just run into it. GOOD LUCK!!!!!!!!!!!!
If you get all eight badges then you can verse the elite four. They are really good and if you beat them you become the champion.
beat elite 4 5 times then beat 30 different trainers isn't that good
lv 60+ because there are 50-70 so you are gonna need good pokemon.
Have good Pokemon with good moves at high levels. And a lot of revives, full heals/full restores and hyper/max potions.
Emerald as alot more features than firered and leafgreen including Pokemon contests, the battle frontier and you can catch certain Pokemon firered and leafgreen both can't get over all if you want to buy a certain GBA Pokemon version get Emerald but leafgreen and firered are good choices to that's because it includes the new sevii islands to explore and the game has a little more difficulty in it that is actually a good thing by the way.
Rescue the man trapped by team rocket in the Pokemon Tower. Then go to his house (it is in the same town) and he will give it two you. P.S: Catch the Snorlax if you can, it is a good Pokemon
There is no easy way to beat the Elite Four. You have to level up your Pokemon and use the right types of Pokemon against each of the elite four (i.e. don't use a fire-type Pokemon against water-type. Use electric instead). I recommend level 60 or so for the Elites. Good luck!
Shellder is a version exclusive Pokemon only found in Fire red. But, Instead of Shellder, you can get Slowpoke, if you use a good rod in the Vermillion city harbor.
