Great Old One

The Old Ones, sometimes known as the Great Old Ones, were beings from before the universe, according to the Doctor. (NA: White Darkness, All-Consuming Fire, MA: Millennial Rites)

Folowing the demise of the last universe, they passed on into this one in which they discovered they had god-like powers with which they manipulated the universe. (MA: Millennial Rites)


 * The appearance and powers of the Old Ones vary from entity to entity. They all have, in Human terms, immense powers.

Behind the Scenes
The Old Ones originated out of the Cthulhu Mythos, a shared universe based on the writing of H.P. Lovcraft and to an extent, some of his contemporaries. A few characters and concepts in televised Doctor Who, such as Sutekh (though based on an actual ancient Egyptian god) and the Fendahl, had shown the apparent influence of the Mythos. However, not until the novels White Darkness, All-Consuming Fire and Millennial Rites did beings explicitly referred to as Old Ones appear in fiction set in the Doctor Who Universe.

The latter two books took known Doctor Who enemies, such as the Animus and retconned them into having links to the Mythos. The Taking of Planet 5 revealed that the Cthulhu Mythos also existed in the form of fiction in the Doctor Who Universe. Though the established Cthulhu Mythos and the Doctor Who version have some differences (the idea of the Old Ones originating before the universe originates in Doctor Who novels, for example), stories set in the Mythos frequently contradicts itself.
