Hatterene is a small humanoid Pokémon with a thin, white body. Its head is round, has a small mouth, narrow black eyes with white pupils, and two elliptical pink markings over each of its eyes resembling eyelashes or eyebrows. It has extremely long, layered, symmetrical hair, far longer than its body is tall; much like a cloak, the hair on its head drapes to the ground and swathes around it to conceal much of its true body, which is adorned by a pink semi-translucent dress that gives it a much taller silhouette, resembling that of a stereotypical sorceress or witch. This hair is colored in a gradient of baby-blue, pale pink, and white from its upper portions downwards. The hair above Hatterene's head is shaped like a wide-brimmed witch's hat with a conical shape serving as the crown of the hat formation. Extending from the pointed end of the hat is a single tentacle that ends in a pink bulb and a consecutive baby-blue bulb that has a trio of sharp claws, which can articulate in a manner similar to fingers, jutting out of it. Hatterene is a female-only species.
Hatterene has a solitary and reclusive nature, emitting psychic powers strong enough to cause headaches as a method to deter others from approaching and disturbing it. It has also been observed that it dislikes loud noises, tearing apart perpetrators with the claws on its tentacle as a result. Due to its long hair obstructing its floating body, Hatterene's main forms of locomotion are levitation and short-distance teleportation. This Pokémon is also known as the Forest Witch.
Thanks to powerful Dynamax energy that allowed it to assume a Gigantamax form, Gigantamax Hatterene has grown to a colossal size. While its physiology remains vastly the same, its black eyes are now blue with white pupils. In addition to this, its hair has grown and increased in volume, forming a chamber of sorts that its body sits in. On both sides of this chamber are a pair of teardrop-shaped openings. The hat-like formation on its head has also changed, with the brim being thinner and draping around it and the crown ending in a pink bulb. Attached to the said bulb is a larger baby-blue bulb that has three, long tentacles tapering from it. As seen with all Dynamax and Gigantamax Pokémon, three red clouds loom and swirl above the hat of Gigantamax Hatterene.
Known as the Raging Goddess, Gigantamax Hatterene has the ability to sense the emotions of creatures from over 30 miles away, and it will become enraged and attack if it senses any hostility. Its tentacles are capable of firing off energy beams akin to lightning.
Hatterene is the only known Pokémon capable of using the move Magic Powder and the exclusive G-Max Move G-Max Smite.
- Hatterene, Grimmsnarl, and their evolutionary families can be considered counterparts. Both are Generation VIII Pokémon evolving once at level 32 then at level 42. Hatterene and its pre-evolved forms are female only, while Grimmsnarl and its pre-evolved forms 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, ogres, and goblins. Lastly, both are the signature Pokémon of one of the rivals from Pokémon Sword and Shield: Bede for Hatterene and Marnie for Grimmsnarl.
Origin
Hatterene may be inspired by forest witches from European folklore that are used to frighten children that do not want to sleep or stay quiet, such as Baba Yaga, the hag from the Hansel and Gretel fairy tale, and especially Cuca due to its connection with Grimmsnarl. 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. Its tentacle(s) and aversion to offensive behavior may also be a reference to the sea witch. The hat-like hair on its head seems to represent a stereotypical witch's hat mixed with a hennin.
Hatterene's relatively small body, as well as the "windows" in its hair-like tentacles 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 by the Brothers Grimm, whose hair was long enough to reach the ground from the top of her tower.
Name origin
Hatterene may be a combination of hatter and serene.
Brimuon may be a combination of brim and 無音 muon (silence).
