Manaphy is a small, blue, aquatic Pokemon with stubby feet and club-like arms that are longer than its body. It has a red gem on its chest and a yellow dot below the gem. Its onion-shaped head has a pair of long blue antennae, which have small spheres on the ends. Its irises are dark blue with yellow sclera, and there are two yellow dots of "eyelash" markings extending from the eyes. Eighty percent of Manaphy's body is made of water. It is highly susceptible to its environment, and swims long distances to return to its birthplace. It is born with a special power that allows it to bond with any Pokemon. Manaphy can switch the perspective of people, and Pokemon, with each other using its signature move, Heart Swap.
