Wooper is primarily a blue, amphibious Pokémon that looks like an upright, armless axolotl. Its head is large in comparison to its body and it has small, round, black eyes. The Pokémon features purple, branching gills on either side of its head; males have more branches than females. Wooper stands on two small, round feet and possesses a large, thick tail. Dark blue curved markings adorn its belly.
In the anime, it's suggested that Wooper is rather dim-witted and oblivious to its surroundings. This Pokémon mostly resides in cold water. When sleeping, it partially buries itself in the mud at the bottom. Occasionally, when the air cools in the evening, it leaves the water to search for food along the shore. While on land, it covers its body with a slimy, toxic film to prevent dehydration and insulate against the cold. Touching this film barehanded results in a sharp pain. Wooper is timid and tends to stay close to Quagsire. Arbok is a natural predator of Wooper.
Forms
Wooper has a regional form: Paldean Wooper.
Paldean Wooper from the Paldea region has brown coloration, with two pairs of bone-shaped gills extending from its head, as well as an eight-pronged pattern on its stomach. These Pokémon once lived in water during ancient times but were forced out of their territory. Consequently, they adapted to living on land, particularly in marshes. Paldean Wooper uses two adaptations to survive on land: its gills have hardened, and it coats its body with a poisonous film to avoid drying out. However, these changes resulted in Paldean Wooper having heavy bodies and being able to move only very slowly. To defend itself, Paldean Wooper can use its gills to release a potent poisonous liquid. They travel and work in groups of three or four and enlist the help of their evolutionary relative, Clodsire, to cross water. Despite these adaptations, Paldean Wooper can still float or swim in water.
