you beat the last gym leader in johnto
He's called Green and he's the gym Leader of the last Gym. Beat all the other gyms then beat him.
Well the last gym leader is a dragon type leader so you need an ice type pokemon and/or dragon type pokemon. Idk what his name is but a guy gives you a level 15 Datrini and it is a dragon type pokemon. For an ice type pokemon, go back to the cave (idk the name of the cave but it is a ice cave) and get an ice type pokemon like swinub and raise him and beat Blair!
If you mean Clair, then you should probably use ice type pokemon.
train your pokemon more.
