It's a long and VERY infurinating process, but I promise you Heatran is worth it when you're done:
When you get to the survival area, go to the house west of the Pokemon center. Talk to the old man then go to stark mountain. You'll meet Buck, and he askes you if you can go with him. He'll steal the magma stone, and run away.
Go out of Stark Mountain and go back to the old man's house. Buck is the old guy's grandson. He tells Buck to return the Magma Stone. So you go back to Stark Mountain again. Go to where Buck stole the stone. You'll see him return it.
Go out of Stark Moutain again.
Go back to Stark Mountain to where the Magma stone is. Heatran will be there.
stark mountain
Stark mountain. its on level 70
to stark mountain to catch hetran
go into stark mountain and pick up the rock and heatran will be there, but you have to have the national pokedex and have beat the pokemon leauge.
you go to the core and battle a hetran just like you normally do
you need to all ready beat the champion then go to the Pokemon league once u have seen all the Pokemon and have the national dex u have to help some one through stark mountain... then she will leave and u have 2 go to her house and talk 2 her... then go back to stark mountain and go in to the end... there will be hetran and u can battle him! - Hope It Helped! :]
He is in Stark Mountian in the Survival area
first u travel up to stark mountain then get to the top of it then u go bak down and in one of the houses in the survial place or fight area u talk to someone and he should go bak up stark mountain then when u follow him bak up to the top of stark mountain and then u fight hetran
You need to go to stark mountain then you lead the guy through the mountain then you leave and go to a house in the survival area and go back to where the guy got the magma stone and Hetran will be there
you can get a persain by going near stark mountain and they sometimes appear there
there is no stark mountain. stark mountain is only in DPP
In smaller words go to survival area, then talk to Buck and he says he will put the stone away, so then go back to the mountain and you battle Hetran!!!.
