Komala is a gray Pokémon similar to a koala. It has large, rounded ears with light orange fur on the inside. Its large, ovoid black nose extends up between its fluffy white eyebrows, and there are additional white puffs of fur on each cheek. There is a small ruff of longer, gray fur around its neck. Each hand is black with five short fingers, and it has three black claws and a black paw pad on each foot. Its underbelly is white, as is its short fluffy tail. Komala is usually seen holding a short wooden log, which it is given at birth. The log is typically a light brown with darker, oval markings all over it. The ends of the log are tan with the growth rings visible.
This Pokémon stays asleep from birth to death, staying this way because of its diet of certain leaves containing poison only Komala can break down, which induces sedative properties. While its expression sometimes changes as if it is aware of its surroundings, this appears to be a result of its dreams instead. It is able to eat, travel, and even battle without waking. If the log pillow it clings to is removed, it will be unable to sleep well and thrash wildly. However, it will sometimes cling to the arm of a Trainer it trusts. During a deep sleep, it stops moving altogether. According to ancient people, if a small amount of the saliva created when it eats leaves is watered down and ingested, one will be able to sleep well. This diluted saliva was also historically used as an anaesthetic for surgeries. Hypno has been known to hunt this Pokémon in Alola, appearing to prefer them over humans.
Komala is the only known Pokémon with the Ability of Comatose.
- Komala shares its category name with Musharna. They are both known as the Drowsing Pokémon.
Komala appears to be based on a koala and their tendency of sleeping up to twenty hours a day. Given its constant sleep, the log it holds is likely meant to represent a body pillow or dakimakura. The log held by a Shiny Komala closely resembles a forest red gum, a common habitat for koalas.
Komala may be a combination of coma and koala.
Nekkoara may be a combination of 根っ子 nekko (root; tree stump), 寝 ne (sleep), 子 ko (young animal), and koala.
