A level 60 or up starter Pokemon
dialgua or palkia
and any Pokemon over 60 just not graveler
the best Pokemon for the Pokemon league is definetly latios
Have a good Fire and/or Ground Type...
go to the resort area and find a syther to battle and it will level your Pokemon about 615 points ________________________________________________________________________________________________ What about before the Pokemon league?
Diamond is not a Pokemon but i think Arceus is one of the strongest Pokemon ever.
the best Pokemon on diamond would be arceus but you can only get that from action replay, other than that i think the best Pokemon would be giritina..
Palkia
in my experience its best to do such things after the Pokemon league. that's how i made my golbat into a crobat at lvel 22 and eevee into an espeon at level 18
the best Pokemon in diamond is arceus, but you have to use action replay or wi-fi mystery gift
No Arceus is the best Pokemon in Pokémon Diamond.
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
a lot of legendary Pokemon
