Racnoss

The Racnoss were an ancient race of aliens from the Dark Times of the universe. (DW: The Runaway Bride)

Appearance
The Racnoss looked like massive half-humanoid half-arachnid beings, with blood-red skin and a crested skull. (DW: The Runaway Bride)

Personality
The Racnoss were insatiably hungry, even at birth, and so invaded planets to feed off all life on them. This led to several advanced races coming together to destroy them later on, and their reasons for trying to destroy Earth. (see History section below). (DW: The Runaway Bride)

Life Cycle
The Empress of the Racnoss was no different from other Racnoss physically, but she apparently was the only one who had the duty of laying eggs which hatched into other Racnoss, meaning that the entire Racnoss race were the children of the Empress. (DW: The Runaway Bride)

Technology
Most of Racnoss technology was made of a fine, silk-like substance, strengthened and protected by Huon energy, including their spacecraft, amongst other things. (DW: The Runaway Bride)

History
The Racnoss evolved in the Dark Times of the universe and were wiped out by the Fledgling Empires over 4.6 billion years ago. Nearly all of the survivors of the race escaped in their spacecraft to where the Earth would later form, serving in place of a planetesimal as its core, hibernating for billions of years, with the exception of the Empress who would later come to Earth in her ship, the Webstar, seeking to use the Huon particles which had been recreated by the Torchwood Institute as a means of resurrecting her people and destroying Humankind for her race to feed on.
