Thiima

The Thiima is the villainous force from G-Darius. They are a mechanical alien race that exists for the sole purpose of protecting the peace in the entire universe, staying dormant in a different dimension.

The inhabitants of the planet Amnelia, a very advanced civilization, waged a long war that ended with the destruction of an entire planet. This prompted the awaken of the Thiima, which sensed Amnelia as a threath to the peace in the universe, immediately attacking Amnelia and easily crushing their resistance. The Amnelian managed to get a piece of a Thiima battleship and, using it's technology, they created the Silver Hawk, a spacecraft capable of wielding multiple weapons. Two pilots are sent to fight the Thiima, tracking them to their origin, a planet that later became known as Darius. The two pilots, Sameluck Raida and Lutia Fenn, sacrificed themselves to defeat the Thiima, but a portion of a Thiima battleship is retrieved by a malevolent army known as Belser, which used their forbidden technology on it's own battleships.
