well, there isn't any, just the eight gym leaders
They are the same levels as the previous Elite 4, well i am currently just about to enter Mt Silver (After winning the 8 Kanto Badges) and so far the Elite 4 have the same leveled Pokemon.
i am pretty sure you can in the kanto region in soul silver after you defeat the elite 4
you start out in the johto region if you mean kanto you have to beat all the gym leaders and the elite 4
the elite 4 is in kanto
yes you can but you have to beat the elite 4 first
There are at the Indigo Plateau in Kanto but 1st you have to go through the Victory Road and beat all 8 gyms and catch lugia in Johto.
After you beat the 8 Kanto Gyms, if you return to the indigo plateau you go through the same elite 4 and champion, but their levels are now between 60s and 70s and they have different pokemon, some from sinnoh and hoenn as well.
No but you can catch many of the Pokemon in Sinnoh after you beat the Elite 4
go into veridian forest in kanto (after the elite 4) and the 2nd to last patch of grass has pikachus. They are very hard to find, so be patient. Hope i helped!
yeh to get kanto legends beat the kanto elite 4 and its champion. do the same as the others
Once you have beaten the elite 4 and the jhoto league champion go to Kanto and when you are in Saffron city head to the far right and go through the bridge and then you will be in lavender town
To get the Rainbow wing you must beat the Elite 4 and when you do you will have access to go to the Kanto region and when you get to Pewter City talk to the man closest to route 3 and he will give you the rainbow wing
