Like with fire red and older versions at the power station , you have to go all the way through it though
I guess Zapdos
You can't get Zapdos on Pokemon Pearl or Diamond but you can migrate it from Pokemon LeafGreen or Pokemon FireRed.
You have to trade it from Firered/Leafgreen in Pokemon firered/leafgreen you can find zapdos in power plant, but you need surf to get there.
