You can't
Diamond.
you have to evolve aron to a aggron
Aron will evolve into Lairon at level 32, then into Aggron at level 42.
at level 42
get to a certain level above aron and lairon
In Pokémon Sapphire you cannot find Aggron however you can find Aron in Granite Cave and in the Victory Road and then you can evolve it at Level 32 into Lairon and then you can evolve Lairon at Level 42 into Aggron additionally you can find wild Lairon in three areas within Victory Road in Pokémon Sapphire and then you can evolve it into Aggron.
You have to evolve it from an Aron. Arons can be found at the Fuego Ironworks with a PokeRadar. Then you level it up to 32 and you get a Lairon. If you want to evolve into a Aggron as well, level it up to 42.
You cant capture an aggron..though u can raise an aron to become an aggron..go to dewford island..and there head to the north west side ..and enter the cave..in the cave u will find plenty of aron..:)
You cannot just go out and catch an Aggron but you can get a Lairon to evolve when it is a somewhere between lv.40 and lv.45.
aggron
Yes but i would change Flareon to a different type fire pokemon. I would also change Victreebell Bronzong. But Empoleon Dragonite and Aggron are good.
You have to evolve it from Lairon which you have to evolve from Aron. Aron can be caught in the grass patches by Fuego Fireworks by using the PokeRadar.
