if it is the first time you are fighting elite 4, the strongest is lvl 63, your rival's starter pokemon. Hope ive helped
If you mean "what levels should your Pokemon be to defeat the elite four" then I suggest all of them be at least level 50.
it's the same in Pokemon ruby sapphire and emerald
he stays in the elite four as champion
You need to beat the elite four and get the national dex.
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 :)
beat the elite four 100 times to get fire, ice, and thunder punch all at once
No, it does not. you can challenge the Elite four as much as you like.
You beat all the gym leaders then the elite four
with skills :>)
he stays in the elite four as champion
i had all mine over lvl 50...except for a lvl 49 pidgeot
