Hiponea resemble a cross between horses and fish, similar to the mythical Hippocampus. They are light blue, with a horse-like head and flipper-like front limbs. They have fins on their heads and necks instead of manes, and fish-like tails with fan-shaped fins. They also have four shingle-like scales on their undersides.
Because of their powerful fins and tails, Hiponea can swim very fast in any direction, even backwards. They can also store water in a special swim bladder located in their chests, and shoot it with incredible force. Their ability, Torrent, gives them a boost in power when health is low.
Iron and Copper = "This little Pokemon lives near the water's surface, where the water is clear. His tail and fins allow him to move in almost any direction while swimming, even backward. He is very docile and smart, but a very good fighter too."
