You need the secret key found in Pokemon mansion.
The 7th leader is Blaine. He uses fire pokemon.
The seventh gym leader in Pokemon Diamond is located in Snowpoint City. Her specialty is Ice type Pokemon, so make sure and have a powerful Fire type. Good luck!
The 8th Gym Leader is Giovani (sp?) a.k.a. the leader of Team Rocket. He lives in Viridian City. You have to beat Team Rocket in every place they are (the Pokemon tower, silph co., game corner) and then of course battle the 7th leader/the fire leader (haha forgot his name). The gym in Viridian City then should be unlocked and you can go inside.
I taught my Blaziken these moves: Hyper Beam which should be great against any Pokemon that the Mossdeep Gym Leaders, Blaze Kick which could knock the crap out of Xatu and Claydol, Fire Blast, the most powerful Fire type move in Pokemon history.and Rock Tomb which should take down Xatu, Solrock and Lunatone. Good Luck!
there is none. You will be stuck in sinnoh region. just an advice, don't play hacks again.
The 7th leader is Blaine. He uses fire pokemon.

The 7th gym leader is Blaine. He the gym leader of Cinnabar Island gym. He uses Fire type Pokemon and he will give you the TM that contains Fire Blast when you defeat him.
the best way to beat the 7th gym leader is with a fire type Pokemon
Get a fast fire pokemon, go to the mall and buy the TM fire blast. Then go to snowpoint city, challenge the gym leader and you should do fine :)
This TM is given to you by the 7th gym leader Blaine after defeating him.
Use a fire, fighting, or steel type.
It is in Viridian City. After you have beten the 7th gym leader it is open
It should be really strong on the 7th gym leader in Pokemon fire red i tired it and i won the 7thgym badge and now you can do it. the weakness of fire Pokemon is electricity and water and fighting lv 45 - 50

Tou have to turn on all of the switches and then go to where you started (the entance door) and then you take the pointy arrow pad on the left and fite the gym leader
