Seaking punches above its weight class thanks to Swift Swim. It doubles its Speed in rain, which is enough to make up for stats that don't impress on their own. Only weak to Electric and Grass. Known as the Goldfish Pokemon.
Nothing fancy in Seaking's spread. It leans physical with Attack out front. And you'll get 2 Attack EVs per KO for it. Follows a medium-fast 1M XP curve.
It is the male’s job to make a nest by carving out boulders in a stream using the horn on its head.
Seaking Weakness
GoodSeaking's Water typing leaves it vulnerable to Electric and Grass moves. The Water typing picks up 4 resistances to work with. Lightning Rod grants an additional Electric immunity, reshaping the matchup chart. With 80 HP and balanced defenses, Seaking can afford to eat a neutral hit or two.
Seaking is what Goldeen becomes. Breed it for Goldeen eggs (average hatch time). No compatible partners for breeding via one egg group. Eggs are average hatch time. The evolution from Goldeen pushed Seaking to 450 total stats. HP saw the largest single gain at +35.
How to Evolve
Breed with Seaking to get Goldeen eggs easily from the Water2 egg group.
Most things take neutral or super-effective damage from this set. Seaking runs Ice and Normal coverage backed by Life Orb for extra damage on every hit for a health trade. Flexible EVs EVs and Lightningrod make the coverage actually threatening.
