Zapdos has the form of a large bird with black and yellow plumage. Its spiky feathers make it appear to be made of lightning. Its tail feathers stick out in several directions, furthering this illusion. A large crest of feathers decorates its head, and distinctive black rings encircle its eyes. Its beak is very long and thin. While Zapdos is the smallest and lightest of the legendary birds, it is still a large Pokémon.
