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.

Gorebyss Weakness

Good

Gorebyss 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.

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.

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 can't be caught in FireRed & LeafGreen. Transfer Clamperl from Ruby, Emerald, or Brilliant Diamond and evolve through the 2-stage line to get it. The step cards below map the full chain.

Trade Evolution Required — Requires trading with another player

How to Obtain Gorebyss in FireRed & LeafGreen

  1. Clamperl
    Step 1Obtain Clamperl

    Catch in the wild in:

    Then trade to FireRed & LeafGreen to continue the evolution chain.

    Also found in:

  2. Gorebyss
    Step 2Gorebyss
  • Gorebyss looks average on paper at 485 BST. But Swift Swim is why it sees play — build around that and it pulls its weight. C-Tier attacker on our tier list.

  • Gorebyss's biggest threats include Manectric (Electric) and Venusaur (Grass), all carrying super-effective STAB moves. Only 2 weaknesses means fewer dedicated counters to worry about.

  • Clamperl evolves into Gorebyss while holding a Deep Sea Scale. Gorebyss is the final evolution in a 3-stage line starting from Clamperl. At 485 BST, it's got solid stats to work with.

  • 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.
