shaymin
NO, it's not shaymin.
It is torterra, let me prove it. Torterra has awesome defense, and it learns a very powerful move, earthquake, and it learns frenzy plant. Shaymin, is weak, and i killed a level 100 shaymin with a level 100 torterra.
Torterra is the strongest Grass Pokemon in Diamona and Pearl.

The strongest Grass Pokemon is usually considered to be Mega Venusaur. With its high defensive stats and access to powerful moves such as Giga Drain and Sludge Bomb, Mega Venusaur can be a formidable opponent in battles.
You use the Pokeradar in tall grass in Pokemon Pearl version. The grass will shake and show you the location of rarer Pokemon.
Arcues Any of them it depends how you train them.
