Mareanie (Japanese: ヒドイデ Hidoide) is a dual-type Poison/Water Pokémon introduced in Generation VII.
It evolves into Toxapex starting at level 38.
Unlike their Alolan counterparts, the Mareanie of the Galar region have not yet figured out that the branches of Corsola are delicious.
The first symptom of Mareanie's sting is numbness. The next is an itching sensation so intense that it’s impossible to resist the urge to claw at your skin.
