Adamant is +Atk/-Sp. Atk. A speed boosting nature is wasted on Torterra as no matter what he's going to be slow as molasses. --- Pearl Info Name: Stephen FC: 4124 1481 8967 Shinies with Pokeradar in Quote SSBB Info Name: FROST FC: 0903 2408 3455
Adamant boosts your attack base stat and lowers the sp. attack one because you will never use the special attack stat with your Torterra. The best one in my opinion is Impish, like I suggested before, it boosts your Defense stat and lowers the special attack one.
