Gorebyss is a very attractive Pokémon, said to resemble a mix between both a chimera and possibly even a mermaid. Its body is a peachy pink which is said to turn a much more vivid shade after eating and during springtime. Gorebyss' mouth is a thin tube which is used to sip on fluids out of its prey. It has a pair of narrow fins, as well as two purple sea shells in the chest area, similar to a mermaid's attire. Another notable characteristic of the creature is two white stripes right before the tail, a whip-like structure with a purple disc attached to the end of it. Gorebyss also has a thin dorsal fin which is tipped with purple. It is a considerably feminine Pokémon due to its color and eyelashes, however, it is not uncommon to see male versions.
Gorebyss evolves from Clamperl by trade while holding a Deep Sea Scale.
