first fly to the survival arear and head to stark mountain and then the ppl over there will tell you more :)
in Pokemon platnium you need to go to the servival area and then go in the top far left house then you can remach the gym leaders again.
Sorry, there is no other ways, exept if you use GTS or if you have Pokemon Platnium. If yyou have Pokemon Platnium, instert ur platnium game and migrate your Pokemon. Catch your the same legendary u have in diamond or pearl, but the legendaries have to be oppisate genders. trade ur heatran, heatran i descovered only is has a gender.Save when ur about to catch heatren in platnium, if its the same gender turn off ur game but save it before u catch heatren, and it will be another gender.trade to ur diamond game, and put the two heatrens in daycare.wate for about 100 minutes and u have two eggs or so.otherwise u cant clone srry.
Heatran is a Fire and Steel type pokemon.
You can't find Registeel in Pokemon Platnium. You just migrate it in Pokemon Ruby, Pokemon Sapphire, and Pokemon Emerald.
There is no 'platnium', but you can find it on wild pokemon.
you cant catch it in platnium but you can trade it
aggron is weaker than heatran by a mile simply because heatran is a legendary Pokemon
