I say AGGRON because it is a steel type and steel have the least weakness.
that depends on your personal preference i personally think tyranitar over aggron
AGGRON! Rampardos's Attack is higher but his defenses are absolutely horrible.
I say aggron because it has much better defense and in mega evolution it has ultimate defense
aggron is weaker than heatran by a mile simply because heatran is a legendary Pokemon
that's a evolved rydon in Pokemon pearl, diamond or platinum
Aggron is better because of his type(steel). Steel has very little things that are O.K. or even super effective while most things are not very effective
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! :)
aggron
Aggron is a steel type Pokemon
You can't catch aggron but you can catch a lairon at victory road to get aggron train Lairon to level 42.
Aggron is number 306 in the pokedex.
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.
