Cramorant is a blue avian Pokémon resembling a cormorant. It has bright green, large, circular eyes with small pupils and a large, thin yellow beak. It has a ruff of light gray feathers that goes around its torso and sticks out at the back, making them resemble a bib. Its tail feathers have a small dot-shaped marking of this same shade of gray. It has a ruff of feathers on its head, with the largest clump pointing backward and being surrounded by small singular feathers. Its feet are black, webbed, and have three toes. Its wings seem to be perpetually extended.
Cramorant is a gluttonous Pokémon that can swallow other Pokémon whole. Its preferred prey are Arrokuda, but sometimes it swallows other Pokémon such as Pikachu, attempting to spit them out if they realize their mistake. Cramorant are quite strong, to the point where they can knock some opponents out in one hit. They are rather unintelligent as they can't remember which Pokémon they fight in mid-battle, but never forget Trainers that they trust. However, they try to attack their Trainers if they steal food from them.
Cramorant's Japanese name, ウッウ Uu, is a palindrome.
Cramorant is tied with Cleffa for the shortest Japanese Pokémon name in trademarked romaji, with only two letters each. However, Cleffa's name is shorter in kana (ピィ).
