u should use the Poke Raidar to search for rare POkemon. For example, Larvitarar knows the best moves.
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..
the best Pokemon for the Pokemon league is definetly latios
Palkia
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
swampert miltic
Chimchar
in my opinion Pokemon diamond is the best; i have both games but i don't play them.i have played both of them before, but diamond is the best- and its my birth stone =)
the best Pokemon to pick at the start is PIPLUP or CHIMCHAR
