Cresselia

Cresselia has a blue, swan-like body with a yellow underside. It has pink eyes, a dark pink, round tuft on its head, and a pointed, beak-like snout. There are yellow, crescent-shaped ornaments on the sides of its head. Cresselia has glowing, pink, ring-like wings on its sides and back with paw like protrusions resting on its chest. These wings release shining particles and undulate beautifully around the quarter moon. Cresselia has the power to dispel nightmares, and holding one of its feathers is said to bring happy dreams. However, as seen in the anime, it can be quite hostile towards its counterpart, Darkrai. Cresselia is the only known Pokémon able to learn Lunar Dance. Cresselia is a female-only species.
