The Gamilons are a race of blue-skinned aliens that exist in the Star Blazers Universe. They live on their home world of Gamilon (planet), but they were originally colonists from the planet Galman. When their world starts to fail them, they search the nearby Milky Way galaxy, and find Earth. Using their unusual but effective method of terraforming, they launch hundreds of planet-bombs at earth, which are full of radiation. They are not able to breathe in primarily oxygen-filled atmospheres, only in radiation permeated gas, although they appear to have adapted to breathe in radiation free atmospheres during or before the Bolar War.
