Duosion is a pale green Pokémon with a large head, stubby arms, and a body that tapers to a point at the bottom. It has oval, black eyes, and a red, diamond-shaped mouth. It is encased in a darker green, gelatinous substance that forms small, round bumps on the lower sides and over Duosion's head. A small circular piece of matter floats inside this substance over this Pokémon's head. It has two brains, which think independently, causing it to attempt two different actions at once. However, it exhibits greater psychic powers when the brains think alike, it exhibits greater psychic powers, which are said to be able to travel half a mile away.
