on diamond i would recommend a staraptor he is baisicly pigeot
i would try the two methods recommended for getting a black charizard on diamond but if you do not have an emerald game or a diamond game then i have no answer
Arceus
Pokemon diamond
Most game stores.
Dialga!!!
Well the legendary Pokemon is Dialga but most of the other Pokemon are the same.
The best Pokemon on Pokemon diamond is obviously a Bidoof...Joke :)No this is entirley an opinion based question but the best aka most powerful,and most defensive is Diagla
Arceus the Alpha Omega God Pokemon
i would have to say Dark Rai
Most likely.
