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 pink body becomes more vivid with the rise of water temperatures in the springtime.
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.

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.
