Palkia looks dinosaur-like, similar to Dialga, though it seems to be based on a theropod, the bipedal carnivorous dinosaurs. Palkia's body is mainly a shade of light purple, although it has stripes and markings of a darker shade and a grayish-colored arm underside and waist. It has round purple-striped plates on its shoulder area, where two pink pearls lie encrusted with a grey rim encircling them and fins in their back. Palkia's arms have somewhat gauntlet-like extended formations and a purple band of coloration at the wrist. Palkia has a long neck, a pointed white crest on the top of its head that extends to its wings, two strong horn-like tusks on the sides of its jaw, and a powerful tail.
