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.
In autumn, its body becomes more fatty in preparing to propose to a mate. It takes on beautiful colors.
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.
- Fairy type does not exist — Dragon has fewer checks
- Physical / Special split now per-move (introduced Gen IV)
Seaking is what Goldeen becomes. Breed it for Goldeen eggs (average hatch time). A decent partner pool 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 using 19 partners from the Water2 egg group. Notable egg moves include Aqua Tail, Haze, Hydro Pump and 4 more.

The natural movepool does the job, but Aqua Tail and Haze from the egg pool give Seaking something extra. Pair those with Hydro Pump and Surf for STAB and coverage across 8 types for reach, and the kit fills out nicely.

Seaking looks average on paper at 450 BST. But Swift Swim is why it sees play — build around that and it pulls its weight. D-Tier on our tier list.
Goldeen evolves into Seaking at level 33. Seaking is the fully evolved form. It sits at 450 BST in its evolved form.
Seaking gets Swift Swim, Water Veil, and Lightning Rod. But Swift Swim is the one that matters — it's the centerpiece of every viable set. Build around that.
