you first have to finish the problems in olivine city (medicine for amphardos) and the problem in goldenrod city at the radio tower, and after you finish, you get to battle claire. once you defeat her she will tell you to go to dragon's den pass the test that her grandfather gives you and and she will give you her badge. (:
Beat the other Gym Leaders in Johto, then WALK YOURSELF to Blackthorn City and battle Claire. You have to go through the Icy Path, which is annoying w/o patience because of the slippery floors.
Beat the other seven gyms and then surf to it in blackthorn city
the fith gym leader in crystal is on an Island in the southwest of Johto. use surf to get to him
Gym Leader Jasmine of Johto will give it to you. She is located at the shore in the northeast part of Sunyshore City.
Claire is the Blackthorn City gym leader who uses Dragon-type Pokemon.
In order to activate the time travel event that involves Giovanni and your Rival, your Celebi needs to be a Fateful Encounter Celebi that was given out at U.S. Gamestop stores across the country and you also need to have stopped Team Rocket's takeover of the Goldenrod City Radio Tower. The takeover will not happen until after you have 7 Gym Badges meaning you have to defeat Falkner the Violet City Gym Leader, Bugsy the Gym Leader of Azalea Town, Whitney the Goldenrod Gym Leader, Morty the Ecruteak Gym Leader, Jasmine the Olivine City Gym Leader, Chuck the Cianwood Gym Leader and Pryce, the Gym Leader of Mahogany Town.
That's never going to happen, since in Pokemon diamond and pearl there arent any gym leaders from johto and kanto you can battle. there is only one from johto jasmine and she only participates in pkmn contests. So if you want to beat all gym leaders from johto and kanto get a fire red and a crystal, lol or just create your own Pokemon game, XD!!
The 5th gym leader in Johto is Chuck. He is located in Cianwood City.
you battle them in the dance center after you defeat Claire, the last gym leader in johto
If its for Johto... Go through Ice Cave to Blackthorn City and Claire will be in her gym... If for Kanto then you have to beat the first seven gym leaders then go to Cinnabar Island and Blue the sixteenth and final gym leader will be waiting to tell you that you can now challenge him in his gym in Viridian City.
The gym is in blackthorn city go west then north
Bugsy in Azaelea town!
The eighth gym leader is Claire in Blackthorn City
claire
the fith gym leader in crystal is on an Island in the southwest of Johto. use surf to get to him
Whitney at Goldenrod city.
You have to enter the Pokemon League.
Falkner is the first gym leader in the Johto region. He uses a Lvl 9 pidgey and a Lvl 13 Pidgeotto, so he's not as much of a pushover as he was in G/S/C.
go to vilet city.
