Hatterene is a small humanoid Pokémon with a thin, white body. Its head is round and has a small mouth, narrow black eyes with white pupils, and elliptical pink markings over its eyes resembling eyelashes. It also has extremely long hair, far longer than its body is tall; it conceals much of its true body and gives it a much taller figure resembling a long robe or dress. The hair colored in a gradient of pastel-blue, pink, and white from its upper portions down. The hair above Hatterene's head is shaped like a pointed witch's hat with a single long appendage extending from the point, ending in a pink bulb resembling a bangle and a claw with three digits. Hatterene is a female-only species.
Hatterene has a solitary nature, emitting psychic power strong enough to cause headaches to deter others from approaching. It also dislikes loud noises, tearing apart perpetrators with claws on its tentacle as a result. Due to its long hair, Hatterene's main forms of locomotion are levitation and short-distance teleportation. This Pokémon is also known as the Forest Witch. Hatterene is the only known Pokémon capable of using the move Magic Powder.
Gigantamax Hatterene has four openings in the hair around its main body, and its hair tentacle splits near its base into three tentacles. Known as the Raging Goddess, Gigantamax Hatterene has the ability to sense the emotions of creatures over 30 miles away, and it will become enraged and attack if it senses any hostility. Its tentacles are capable of firing energy beams like lightning. Gigantamax Hatterene is the only known Pokémon capable of using the exclusive G-Max Move G-Max Smite.
- Hatterene, Grimmsnarl, and their evolutionary relatives can be considered counterparts. Both are Generation VIII Pokémon evolving once at level 32 then at level 42. Hatterene and its evolutionary relatives are female only, while Grimmsnarl and its evolutionary relatives are male only. Their final evolved forms are both Fairy-type Pokémon with identical base experience and catch rates, and each Pokémon in each evolution line have the same base stat total as their counterpart (e.g. Hatterene and Grimmsnarl both have a base stat total of 510). Both Pokémon also have a Gigantamax form, a signature G-Max move, and use their body hair as their primary weapon. In addition, both Pokémon are based on mythical beings from European folklore and mythology: Hatterene resembles witches, and Grimmsnarl resembles trolls and ogres. Lastly, both are the signature Pokémon of one of the rivals from Pokémon Sword and Shield: Bede for Hatterene and Marnie for Grimmsnarl.
Origin
Due to its connection with Grimmsnarl, the name of its exclusive G-Max Move that alludes to discipline and full female gender ratio, Hatterene may be inspired by the Cuca, the female counterpart of a shapeshifting bugbear, depicted as a forest witch, both mentioned in lullabies and used in some cultures to frighten children that do not want to sleep or stay quiet. Hatterene's face and actual body also appear to bear a strong resemblance to a Roswell grey alien, an archetypal depiction of extraterrestrial life in popular culture.
Given its title as the forest witch, it also seems to be based on the hag from the Hansel and Gretel fairytale by the Brothers Grimm, that kidnap children with the intent to devour them. Its appearance may be inspired by Harionago, a female ghoul from Japanese folklore described as a beautiful woman that uses its extremely long hair tipped with thorn-like barbs to attack. Hatterene's relatively small body, as well as the "windows" in its hair in its Gigantamax form, may be based on the common fairy tale motif of a girl locked away in a tower; in particular, it may reference Rapunzel, whose hair was long enough to reach the ground from the top of her tower.
