Swanna is a swan-like Pokémon with primarily white plumage. Its beak is long and yellow, topped with a black cere, with several white-colored feathery features adorning its head. The more rounded of the features are to the sides of its head, and the more pointed feature is atop. As distinctive among swans, Swanna possesses a long, curving neck. Two light-blue feathery features, like those on the sides of Swanna's head, are present on Swanna's underside, and Swanna's large wings are positioned in a way unconventional for birds. Swanna's legs are small, and its webbed feet dark in coloration.
