The weakest Pokemon in diamond is a magikarp. It is also the weakest of all the Pokemon existed. Magikarp is weak but it will evolve to a mighty gyarados.
fury cutter .
Nope. the weakest pokemon would actually be sunkurn. It has the lowest defense stats out of any pokemon, really low base attack and very few decent moves. it is by far the worst competitive pokemon.
The charcoal item in Pokemon Diamond powers up your attack by 20%.
The meteors in Pokemon Diamond can change Deoxes's Form. (Attack, Defence, Speed, and Normal.)
you don't
This is a matter of opinion. MAGIKARP he's the weakest Pokemon of all but he evolves into an awesome garadose(suckish spelling I know)
yes
blast burn
The expert belt in Pokemon diamond and pearl increases the power of a super effective attack.
The weakest Pokemon move is splash it doesn't do anything
The weakest in the whole entire game is magikarp
