All known Pokemon have a weakness. But there is only one knoen Pokemon that does not have a weakness and that is Spiritomb he is found in both Pearl and Diamond but it is hard to catch. My reccomendation is get it from a trade in Wi-Fi or a friend.
Dark Pokemon are Psychic Pokemon's weakness.
all you need is a ground type, but for octillery, maybe use an electric Pokemon or grass one, or it will slaughter your ground one otherwise
use Pokemon diamond/peral/platinum's effect calculator and find out what the gym leaders weakness is
Pokemon diamond
Pokemon diamond Pokemon diamond Pokemon diamond
you cant be a Pokemon in Pokemon diamond
The weakness of electric type Pokemon is ground type Pokemon.
Rock Pokemon's weakness is water types so in the game choose the water starter
