well, i used swampert, pikachu, groudon, gardevoir and medicham and swellow all level 47-52 :)
beat the elite four get the pokedex and collect all pokemons
u must have the right pokemons yeah ;)
The Elite Four becomes stronger by itself once you beat them. All their pokemons become about 20 levels stronger after the first time you beat them :)
you can go and catch rare pokemons,go to different places,and yea
You have to use your best Pokemon and you have to buy lots of revives and hyper potions to help you when your pokemons hp. The elite four is strong but try your best.
you simply have to beat the elite four and go to mr pokemons house and he will give you it
Well you must first beat the elite four and enter the hall of fame. After you have at least beat them once battle them again. There pokemons levels will be even higher than before. The highest level that they will have will be a level 77 Garchomp. I hope that i helped!
You can use a strong Pokemon to hit all the Elite four's Pokemon and champion Lance's Pokemon (in HeartGold). It depends on your Pokemon level but you can use ice types to beat Lance's Pokemons so it's easy to beat Lance.
Fire and water are the best combination to beat the elite 4.
red or the elite four if you beat red the elite four Pokemon will be jacked up or red again after you beat the elite four his Pokemon are the same levels as before
In Ruby and Sapphire yes you need to beat the Elite Four first, but in Emerald you can catch Raquazza before or after you beat the Elite Four.
Yes. You must beat the Elite Four to get anywhere in Kanto.
