nothing
beat the other 7 gyms in kanto and talk to the 8th gym leader on cinnabar island. he will leave and go back to the gym
The final gym is the Viridian City Gym. Blue is the Gym leader.
Blackthorn city, in kanto you find him at cinnibar island show him your 7 kanto badges to make him go back to the gym then you can battle him.
face him, click on him, then have courage and believe!
Not enough info: which gym leader?
the last gym leader is Blue.When you go to the seventh gym leader Blaine you should see Blue and asks you if you have 7 badges then you beat Blaine and go to Blue and he says to meet him at his gym
cinnabar island. he will go to the gym after getting all the 7 kanto gym badges
I think you need to beat 7 kanto gym leaders to fight him.
hes on cinnabar island.you cant battle him unless you got 7 kanto badges
Blaine.
cinnabar island need 7 kanto badges
