Diamond is not a Pokemon but i think Arceus is one of the strongest Pokemon ever.
The Pokemon center on victory road. for Pokemon levels around 20 go to the diner in the beach city.
The best place to train a lv 30 fire type in Pokemon diamond would be next to snow point city because there are lv 30 Pokemon there that ice and grass but run away from the sneasel.
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..
route 205 for Pokemon diamond, pearl and platinum. the trainers have Pokemon from level 10 to level 17
the best Pokemon for the Pokemon league is definetly latios
Palkia
