Dæmon The Dæmons were a race of powerful humanoid s who profoundly affected human kind . Biology . Dæmons could use their technology to change their size ( TV : " The Dæmons " ) and shape . ( PROSE : " " ) Some appeared as satyr - like humanoid s with reddish skin ( HOMEVID : " Dæmos Rising " ) or thick fur . These often had sharp fangs , pointed ears , thick beards and long horns . Their legs were goat - like , with cloven hooves . ( TV : " The Dæmons " ) During war , Dæmons would manifest in spatiodynamic bodies with vast wings , sweptback horns , and long necks , allowing them to glide through hyperspace with minimal effort . ( PROSE : " Interference - Book Two " ) Some Dæmons wore long , forked tails . ( COMIC : " Voyage to the Edge of the Universe " ) Culture . Like a million other worlds " right across the universe " , Dæmos had " the representation of the horned beast " in its myths and legends . The Beast claimed to be this " devil " , along with all of the others in every religion which had such a figure . ( TV : " The Satan Pit " ) The Third Doctor seemed to initially regard them as not evil , but coldly logical and amoral , without sentiment , which Azal ' s actions would bear out . ( TV : " The Dæmons " ) They did only what they wished ; self - sacrifice would have destroyed them . ( PROSE : " " ) However , they also seemed to organise according to the nuclear family structure and care for their mates and children . ( COMIC : " Voyage to the Edge of the Universe " ) At a later stage of his life the Seventh Doctor had made the acquaintance of a friendly Dæmon known as Bonjaxx and attended a birthday party in honour of him . ( COMIC : " Party Animals " ) Technology . The Dæmons had technology indistinguishable from magic . They possessed matter - energy conversion technology which allowed them to shrink and grow things at will . They used this both to reduce the size of their ships and to manipulate their own size . They also had the ability to set up heat force field s which could disintegrate anything that moved into it . They could animate stone statues , as with the living gargoyle known as Bok . They could also discharge bolts of electricity . A Dæmon could be psychically summoned by a special ritual , three of which were performed by . The ceremony required negative emotions such as fear , which could be provided by frightened human s . The more people that were involved and the more impressive the ritual , the more effective it was . Though these negative emotions could power the Dæmon , it also meant positive emotions could be dangerous . A Dæmon would only appear three times in response to these rituals . Azal offered his powers to the Third Doctor when the Master , who desired them , had proved himself unworthy . This would suggest that they could give their powers if they chose to . ( TV : " The Dæmons " ) Like their peers of the Osirian Court , their technology level qualified them for diplomatic and scientific relations with the Great Houses of the Homeworld . ( PROSE : " " ) History . The Dæmons were an ancient race from Dæmos ( TV : " The Dæmons " ) who were powerful 150 million years BC . They were involved in the Millennium War and were one of the first species to strike back against the Mad Mind of Bophemeral stopping it from using a dark - matter cloud in the Rift of Perseus . ( PROSE : " The Quantum Archangel " ) A Dæmon was one of the only beings to successfully travel to the edge of the physical universe . ( COMIC : " Voyage to the Edge of the Universe " ) The Dæmons studied other races , treating the universe as their laboratory . ( TV : " The Dæmons " ) The Third Doctor said that , circa 100 , 000 years BC , the Dæmons arrived on Earth and helped the human s to overcome the Neanderthal s before trying to lead their evolution and development ( TV : " The Dæmons " ) in exchange for allegiance , as they often did with lesser species throughout the cosmos . Successful experiments were brought to be further cultivated in the Infernal Sphere , ( PROSE : " " ) but failed experiments like Atlantis were dispassionately destroyed . ( TV : " The Dæmons " , PROSE : " " ) According to one account , the Dæmons gave the Atlantean s the Crystal of Kronos , which later indirectly caused the destruction of Atlantis . ( PROSE : " The Quantum Archangel " , TV : " The Time Monster " ) The Third Doctor said the Dæmons inspired myths of god s and demon s and the image of powerful beings with horns , including the Egypt ian god Khnum . They had been " coming and going ever since " . Miss Hawthorne identified Azal as " the Devil " .

( TV : " The Dæmons " ) Wesley Sparks claimed to have duelled Dæmons as one of his many achievements . ( COMIC : " Mortal Beloved " ) In the 20th century , Azal called himself the last of the Dæmons . ( TV : " The Dæmons " ) Near the time of the War , the Dæmons were completely wiped out by some sort of massive cataclysmic event . It was believed to be a battle , as the Dæmon corpses were found in their battle form . Faction Paradox used the skeletal remains of the Dæmons as warships . ( PROSE : " Interference - Book Two " ) After Baphomet and Byzo tried to obtain metagenic field technology from the Great Houses in exchange for information about a crashed timeship on Earth , Lady Thelema used a hand bell , an ancient book , and a candle to kill them .
