Biology

Mareanie is a Pokémon with a purple, stalk-like body and head. It has blue eyes with yellow pupils and sclerae, and three pointed teeth. The body consists of two sections; the top section is slightly smaller and overlaps the lower. On top of its head is a starfish-like collection of ten tentacles. All of the tentacles reach the ground, except for the one directly in front, which is shorter and leaves its face exposed. The tentacles are light blue and covered in purple spines. On top of its head is a purple area with a collection of spikes with a larger, yellow spine in the center. Mareanie is able to regenerate any body part overnight, except its head.

Bruxish feeds on Mareanie, which in turn eats the branches of Corsola - except in Galar, where it has not yet learned about eating them. It uses the spike on top of its head to poison its prey and uses its tentacles to either trap its prey or deal the final blow. In the anime, it has also been seen attaching itself with all of its tentacles and releasing poison through its spines.

Differently colored Mareanie in the anime

James's Mareanie

A female Mareanie debuted in The Sun, the Scare, the Secret Lair!, where she was caught by James. She has a very strong affection for James.

Other

A differently colored Mareanie appeared in Fighting Back the Tears!, where he evolved into a Toxapex. He used to have a crush on James's Mareanie. This one has purple tentacles, and green irises, which gives it a slight resemblance to James.

Minor appearances

Multiple Mareanie debuted in The Sun, the Scare, the Secret Lair!, where they scared off a group of Corsola that Ash was hoping to catch. Kiawe warned Ash that they were dangerous, causing them to flee.

Generation VII Alola

This Pokémon has no Pokédex entries in Let's Go, Pikachu! and Let's Go, Eevee!‎.
Sun It plunges the poison spike on its head into its prey. When the prey has weakened, Mareanie deals the finishing blow with its 10 tentacles.
Moon It's found crawling on beaches and seafloors. The coral that grows on Corsola's head is as good as a five-star banquet to this Pokémon.
Ultra Sun They eat Corsola branches, so Mareanie are hated by craftsmen who work with Corsola branches that have naturally fallen off.
Ultra Moon Aside from its head, its body parts regenerate quickly if they're cut off. After a good night's sleep, Mareanie is back to normal.

Sword The first symptom of its sting is numbness. The next is an itching sensation so intense that it's impossible to resist the urge to claw at your skin.
Shield Unlike their Alolan counterparts, the Mareanie of the Galar region have not yet figured out that the branches of Corsola are delicious.

Trivia
  • When encountered in an SOS Battle as an ally called by Corsola, it will attack the wild Corsola instead of attacking the player's Pokémon.

Origin

Mareanie appears to be based on a crown-of-thorns starfish, a venomous starfish that preys on coral polyps (similar to how Mareanie preys on Corsola).

Name origin

Mareanie may be a combination of marine and meanie.

Hidoide may be a combination of 酷い hidoi (cruel) and 海星 hitode (sea star).
