After You Get All The Badges, You Can Either, Go back to the elite four, ( they have new Pokemon ) or what your realy meant to do is go to mount silver, climb to the top and fight "Red" the best person in game, once you do it will say the end.
i think so because my heart gold connected with platinum he has his 16 badges but when pplatinum looked at heart gold case it showed 8 sinnow badge slots!!
go to pallet town after you have 16 badges and go to professor oak's lab
you have to get 16 badges and go to the end of the cerulean cave and mewtwo will be waiting there
There are 8 badges in each and every Pokemon region except for the Gold and Heart Gold versions/Silver and Soul Silver. (there are 16) (if that wasnt known..)
Professor Oak gives it too you when you have obtained all 16 badges.
You are in jhoto first then when you have all the 8 gym badges you can go to kanto and get 8 more badges which will be all 16 badges then you can challenge the pokemon league. Hope that helped.
U need to get all 16 badges then go pallet town in kanto
Your next objective is to get the other four. There are a total of 16 gym badges. You can only get the sixteenth gym badge if you have the other fifteen.
I assume you have either Heart Gold or Soul Silver. These are the only Pokémon games that have the ability for your player to get 16 badges. Every other game has 8 badges. If you mean specifically how do you obtain badges, beat the gym leaders in the different towns. If you want a complete walkthrough of how to get every badge, just search "[game] walkthrough".
Get all 16 badges and visit the Professor in his Pallet Town lab. He'll give you the HM.
Yes you can get Zapdos in Pokemon Heart Gold. After you get all 16 badges go to the power plant and Zapdos will be waiting there for you. He is at lvl 50.
HM08 Rock Climb is given to you by Prof. Oak after you get all 16 badges.
