Bright Smile

Bright Smiles are extremely rare enemies encountered on the Highway in Mother 3. They look like a sphere with bright teeth. They can only be fought in tunnel sections of the highway. They are known for their use of many PSI attacks such as PK Fire β, Counter, PK Flash and PSI Shield. They are weak against thunder and drop a large amount of DPs after their defeat.
