Seel is technically a pre-evolution of Dewgong, but it holds its own in formats where Eviolite is allowed. Thick Fat halves incoming Fire and Ice damage, adding extra value. Part of the Gen 1 roster. Only weak to Electric and Grass.
You won't find a real weakness in Seel's stat line. It's well-rounded for the Sea Lion Pokemon, and what it does with that depends on moveset and items. Yields 1 Sp. Def EV, on a medium-fast 1M XP curve.
Loves freezing-cold conditions. Relishes swimming in a frigid climate of around 14 degrees Fahrenheit.
