Nothing about Dewgong screams competitive powerhouse, and that's fine. Water/Ice means only weak to Electric, Grass, Fighting, and Rock. Needs some investment to avoid getting outsped. Known as the Sea Lion Pokemon.
Dewgong's spread favors balanced defenses over offense. Sp. Def leads the defensive side, Attack eats the cost. Yields 2 Sp. Def EVs per defeat. Medium-fast 1M XP curve to level.
Its entire body is a snowy-white. Unharmed by even intense cold, it swims powerfully in icy waters.

- Special stat governs both offense and defense — no Sp.Atk / Sp.Def split
