Swift Swim doubles its Speed in rain, adding real value on top of Gorebyss's already solid stats. Water typing means only weak to Electric and Grass. Known as the South Sea Pokemon. Its damage comes from the special side.
Nothing fancy in Gorebyss's spread. It leans special with Sp. Atk out front. And you'll get 2 Sp. Atk EVs per KO for it. Follows a standard growth curve.
Its swimming form is exquisitely elegant. With its thin mouth, it feeds on seaweed that grows between rocks.
Gorebyss Weakness
GoodGorebyss is weak to Electric and Grass-type moves. The Water typing picks up 4 resistances to work with. Gorebyss's physical bulk (base 105 Def) helps cushion physical weakness hits, but special attackers are the bigger threat.
- Dark and Steel types added — Fairy does not exist yet
- Moves are Physical or Special based on type, not per move
Clamperl's line splits into 2 evolutions, and Gorebyss is the trade route. Each sibling form needs a different method to obtain. Breed through Clamperl to get eggs. Gorebyss and Huntail share the same 485 total stats, but they're distributed differently. Check the comparison below to see where each one specializes.
How to Evolve
Breed with Gorebyss to get Clamperl eggs easily using 58 partners from the Water1 egg group. Notable egg moves include Barrier, Body Slam, Confuse Ray and 3 more.
Modest nature gives Gorebyss the special lean it needs to trade hits effectively. Leftovers adds passive recovery each turn, max Sp. Atk and Speed EVs split the difference, and the remaining moves punishes anything trying to wall it.

Gorebyss gets Swift Swim and Hydration. But Swift Swim is the one that matters — it's the centerpiece of every viable set. Build around that.
Gorebyss is a special attacker with base 114 Sp. Atk. Enough bulk to take a hit or two, too. But the speed tells the real story — at base 52 Speed, it won't be moving first often. Fits the attacker role.
Gorebyss appears in 13 games, including Ruby & Sapphire, FireRed & LeafGreen, and Emerald.
Since Ruby & Sapphire, Gorebyss has been in 13 games. Requiring a trade evolution to obtain means it's consistently available but requires more effort than simply catching it in the wild.
