It's fairly easy to beat the Elite Four in Leaf Green if you have the right attacks, Pokemon, and Pokemon levels. My team for the Elite Four are all (legit) Level 100's. Here's my recommended team:
Alakazam:
Psybeam
Psychic
Metronome
Shadow Ball
Hitmonchan:
Brick Break
Seismic Toss
Metronome (you can also have another Fighting attack, such as Mega Punch)
Sky Uppercut
Blastoise:
Waterfall
Earthquake
Strength
Surf
(yes, I know, 3/4 of the attacks are HM's. But it works for me!)
Nidoking:
Mega Punch
Thunderbolt
Ice Beam
Earthquake
Okay! Now, for battling the Elite Four.
The first Elite Four member you will be fighting will be Lorelei. She uses Ice-type Pokemon. I will display the list of her Pokemon when you have the National Pokedex, along with the other Elite Four members.
Dewgong, Level 64
Lapras, Level 66
Jynx, Level 66
Cloyster, Level 63
Piloswine, Level 63
Fighting-type Pokemon are extremely effective against Lorelei's Pokemon, so I would suggest a Hitmonchan or a Hitmonlee.
The second Elite Four member is Bruno, who uses Fighting and Steel-type Pokemon. He will have these Pokemon.
Steelix, Level 65
Hitmonlee, Level 65
Hitmonchan, Level 65
Machamp, Level 68
Steelix, Level 66
I would recommend using a Fighting-type Pokemon on both of his Steelix's, and a strong Psychic Pokemon, such as Kadabra OR Alakazam, on his Fighting Pokemon.
Next is Agatha, the third Elite Four member. She uses Poison and Ghost-type Pokemon. These are the Pokemon she uses.
Gengar, Level 66
Crobat, Level 66
Gengar, Level 70
Misdreavus, Level 65
Arbok, Level 68
You've come so far, but there are two battles left. Next is Lance the Dragon Trainer, who, of course, uses Dragon-type Pokemon. These are the Pokemon he uses.
Gyarados, 68
Kingdra, 66
Dragonite, 68
Aerodactyl, 70
Dragonite, 72
This is where Nidoking comes in. Using Thunderbolt on his Gyarados and Kingdra sure does a lot of damage. On his remaining Dragonite's and Aerodactyl, use Ice Beam, which will be very effective.
Last but not least is your Rival, or, to be exact, the Elite Four Champion! Since you're this far, I'd suggest saving, so if you lose, you can start over. I'm going to provide a list of his Pokemon when he chose Charmander as his starter.
Heracross, Level 72 - use a Psychic Pokemon, such a Alakazam or Kadabra. Psybeam or Psychic (preferred) will be very effective.
Alakazam, Level 73 - keep your Alakazam or whichever Psychic Pokemon you have out, making sure you have Shadow Ball as one of your moves. It will be very effective on his Alakazam.
Tyranitar, Level 72 - a Water-type Pokemon, such as Blastoise, will be perfect to beat Tyranitar.
Exeggutor, Level 73 - using your Nidoking's Ice Beam, or one of your other Pokemon's Ice Beam, will be sure to bring success in defeating this tricky Exeggutor.
Gyarados, Level 73 - a nice Thunderbolt will bring this Gyarados down.
Charizard, Level 75 - three words: a Water-type Pokemon!
And . . . congratulations! You've defeated this long journey of defeating the Elite Four.
I'd suggest that your Pokemon be Level 75 when you have the National Pokedex. Then, soon enough, they'll be the golden level, Level 100.
Good luck! Hope this helped.

I think by beating the Elite Four
after beating the elite four you'd get rainbow pass
Prof oak after beating the elite four.
yes but first you need to get the national pokedex from oak after beating the elite four.
After beating the elite four and getting the national dex.
you breed them on four islands after beating the elite four but you need a boy and a girl or any gender and a diddo answered by ..::Seth::..
After beating the elite four and obtaining the rainbow ticket, heracross can be found in the forest north-east of six island.
after beating the elite four, it would be wild in kanto ONLY if u chose squirtle as ur starter pokemon.
You can go back to Cerulean cave and catch Mewtwo, or simply try to "Catch 'em all"
No its not an HM in leafgreen.
well for me get all three kanto starters a pidgeot a dragonite and golem hope this helps
