Dialga is a dark-blue, sauropod-like Pokémon with some gray metallic portions and light blue stripes. It has a chest plate on its torso, which has a deep blue diamond-like crystal embedded in the center. Dialga has a fin-like structure on its back, three spines on the back of its neck, and a crest on its head, resembling a dinosaur. It also has two structures on the sides of its head that extend outward and resemble horns and fangs. It has three claws on each foot, of the same metallic look as its chest plate. Faint cracks exist across its body. The fin-like structure on its back can be used to focus the flow of time, as seen in Explorers of Time, Darkness, and Sky. (Source: Bulbagarden.net, CC BY-NC-SA)
