This is a list of fictional creatures and aliens from the universe of the long-running BBC science fiction television series Doctor Who, including Torchwood, The Sarah Jane Adventures, K-9 and K-9 and Company. It covers alien races and other fictional creatures, but not specific characters. Individual characters are listed in separate articles.
Note that some information on the page is taken from spin-off media.
The Raak was a sea monster experimented on by Crozier in Mindwarp.
The Racnoss appeared in the Tenth Doctor story "The Runaway Bride" in 2006.
The Racnoss are described by the Tenth Doctor as an ancient race of aliens from the Dark Times of the universe. Half-humanoid, half-arachnid in appearance, they were an invasion force who consumed everything on the planets they conquered. Their race was wiped out by the Fledgling Empires, over 4.6 billion years ago. Although the Time Lords are not specified as being a part of the Empires, the Doctor acknowledges that his people unravelled their power source, Huon particles, and upon hearing the name of the Doctor's planet, Gallifrey, the Empress claims that they "murdered" the Racnoss. The Doctor and Donna Noble are shown witnessing nearly all of the survivors of the race escape in their ship 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 their Empress. The Doctor notes that because the Huon particles ceased to exist, the surviving Racnoss are stuck in hibernation. The Empress is seen coming to Earth in her ship, the Webstar in this episode, seeking to use the Huon particles which had been recreated by the Torchwood Institute using the water of the River Thames as a means of reviving her "children" before feasting on the human population of Earth. The last Racnoss are presumed wiped out when the Doctor drains the waters of the Thames down the shaft leading to their ship; the Empress is killed when her own ship is destroyed by the British army at the order of "Mr Saxon".
