I'm not sure trying to find out myself, sorry.
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
victory road but is rare
You can catch Lairon in the Safari Zone, but you need to arrange the blocks and he'll most likely be in the Peak area in the Safari Zone.
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.
Lairon is a Rock and Steel type pokemon.
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
