you re-battle the elite four i think
there are 8 bages=8 gim leaders
I think it's about 32. ITS 16. 8 FROM JHOTO AND 8 FROM KANTO
get all 8 gym bages
Get all 8 johto badges and go to kanto and beat the elite four. Then go to kanto and get badges 9-16 and then catch all the pokemon and then get the kanto starter from oak and go to mt silver and have atleast lvl 85 pokemon and beat red. That's it.
well you beat all 8 johnto gym leaders and then get to kanto and go to lavender town idiot
after you beat all 8 kanto gym leaders
you beat all 8 kanto gyms then go to prof oak
beat all 7 gym leaders and go to viridayan city gym
Beat all 8 gym leaders in the Kanto and professor oak will give you it
You collect all 8 Kanto badges.
If you mean Kanto, then you have to collect all the 8 gym badges in Johto and then beat the elite four. You will then be given a ticket to the ship, which will take you to vermillion city in Kanto.
In Kanto.
