AGGRON! Rampardos's Attack is higher but his defenses are absolutely horrible.
aggron is better than rampardos because steel type moves are stronger than rock Pokemon.Aggron is a steel type and rampardos is a rock type.good luck. Well to my experience with both Pokemon Aggron is a very good defence type but rampardos has good attack. Happy to help! :)
Sorry but you can't catch one. You can get an aron and evolve it at level 16 into lairon and then level 42 into aggron. Hope it helped
You have to migrate a lairon or Aggron from ruby once you have lairon you must get it to level 42 then it evolves same with Aggron.
I personally like Emerald better, but Pearl has better graphics.
You train them
diamond
its not
neither of them is better, they are both the same, but in diamond, you catch dialga, and in pearl, you catch palkia, and you can catch different Pokemon in each game for example: you can catch this Pokemon in diamond, but not pearl but: you can catch this different Pokemon in pearl, but not diamond
The Pokemon exclusive to Pokemon Diamond are: Seel, Dewgong, Scyther, Scizor, Murkrow, Honchkrow, Larvitar, Pupitar, Tyranitar, Poochyena, Mightyena, Aron, Lairon, Aggron, Kecleon, Cranidos, Rampardos, Stunky, Skuntank, and Dialga.
i reckon PLatinum. it has all the new features but doesnt allow some Pokemon to appear in the wild that do in Diamond/ pearl. but platinum also has even rarer Pokemon that don't appear in pearl/diamond. I have all three. YAY
they are all worth time
Pokemon diamond n pearl it has the recentest Pokemon on and its better graphix
