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
AGGRON! Rampardos's Attack is higher but his defenses are absolutely horrible.
NO you cant catch syther in Pokemon pearl
You can't catch a charizard in pokemon pearl.
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
you can certainly catch Dioxies in the game Pokemon pearl
It's impossible to catch Jiratchi in Pokemon Pearl version.
You can't catch aggron but you can catch a lairon at victory road to get aggron train Lairon to level 42.
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.
In Pokemon Diamond and Pokemon Pearl, there is no possible way to catch a Giritina. You can, however, either catch one in Pokemon Platinum or trade with someone who does have one. In Pokemon Pearl, you catch Palkia at Spear Pillar. In Pokemon Diamond, you catch Dialga at Spear Pillar.
You can't catch it in Pokemon pearl unless you have an action replay. But if you did catch it in Pokemon emerald, sapphire, or ruby, then you can migrate it
NO!!!!! YOU CAN ONLY CATCH PALKIA ON PEARL you can't catch dialga on Pokemon pearl but you CAN trade it you only get both in Pokemon platinum
the best Pokemon you can catch in Pokemon pearl is heatran
