Gamilon

Description
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 Galmon. 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.

Ships
There are many types of Gamilon ships, but most of these are one-of-a-kind or made in small numbers. The Gamilons also are very adaptive, and they will make new types of ships to battle new enemies. The most used ship is the Gamilon Destroyer, and it is seen in the picture below.

Movie Version
A movie was made in Japan in 2010 based on the animated series, using the Japanese name for the series. In Space Battleship Yamato, the Gamilons are not individual, but share one consciousness. They are also much less human like, as 70s era aliens tended to be more human in appearance.
