Heatran

Heatran is not a hard pokemon to catch. In order to catch heatran, you have to beat the elite for, and get the national pokedex. then, go to the survival area. Go across route 226, then head up 227. go into stark mountan. get to the very end of stark mountain

I would recomend using giratina for this battle. heatran's stats are: HP:152

Lv.: 50

Report on moves: Metal Sound. Power: ---, Accuracy:85. A horrible sound like scraping metal is emitted to sharply reduce the foe's Sp. Def stat.

I would recomend using dusk balls. it only took me a couple of ultra balls/timer balls. he is very easy to catch.
