Hatenna is a small Pokémon with a round pink body and a pair of small feet. Most of its body is covered by a blue wig-like feature with a pink, hat-like erect tail. This tail is decorated with a white spot and has a blue bulbous growth on its tip. The flaps on the side of its head appear to be able to function like limbs. It is a female-only species with no male counterpart.
The tail protrusion on Hatenna's head constantly senses and captures other creatures' emotions. As such, Hatenna is a reclusive Pokémon, preferring to live in uninhabited areas. It tends to run away as fast as possible when it senses strong emotions, as exposure to it for too long will make Hatenna tired. It never warms up to anyone that does not have a calm disposition.
Hatenna, Impidimp, and their evolved forms can be considered counterparts.
Both are Generation VIII Pokémon evolving once at level 32, then at level 42.
Hatenna and its evolved forms are female-only, while Impidimp and its evolved forms are male-only.
Each Pokémon in each evolutionary line has the same base stat total, base experience yield and catch rate as their counterpart (e.g. Hatenna and Impidimp both have a base stat total of 265), except for Hatenna and Impidimp's catch rate.
Both evolutionary lines share similarities with mythical beings from European folklore and mythology: Hatenna's family shares traits with witches, and Impidimp's family shares traits with goblins.
Both final evolutions are Fairy-type Pokémon based around long hair that have their Speed drop upon evolution.
