Entity ( The Friendly Place ) The Entity was a Moon - sized telepathic being in a " backwater zone of space " . ARC played the role of the Entity ' s brain . Biology . The Entity was a protoplasmic organism . ( COMIC : " What He Wants . . . " ) It looked like a white amorphous mass that could change form at will . The Eleventh Doctor described the Entity as a mental parasite . It fed off will , ambition , creativity , which were usually tied to the desire to make trouble . Individuals the Entity fed on became docile and ready to accept almost any working and living conditions they were offered . Feeding required direct contact and was more successful if the individual voluntarily invited the Entity into their minds . To achieve this , the Entity created an image of what the individual wanted and could not resist . However , the complexity of this image was limited . For instance , a complex concept from higher - dimensional physics was outside of the Entity ' s capabilities . The absorbed parts of individuals ' minds were digested slowly , making it possible to restore the individuals to their original state if the Entity was sufficiently destabilised . ( COMIC : " The Friendly Place " ) Biography . SERVEYOUinc sent an expedition led by a chief scout to explore the possible uses for the Entity . It wanted to learn , instead it was subjected to an electrocution . Attempting to escape the pain , the brain of the entity , ARC , separated itself from the rest , which he called " mass " . At the same time , the Entity sucked in the Talent Scout . His team towed the Entity to SERVEYOUinc City . ( COMIC : " Four Dimensions " ) A portion of it was separated and sent to Rokhandi . It fed on lifeform ' s creativity , will and desire to cause trouble , which were all interconnected . This was used by SERVEYOUinc to keep customers and employees of Rokhandi World happy and docile . More than a decade after its capture , the Rokhandi portion of the Entity tried to feed on the Doctor ' s desires . When he wished a temporal concept he himself had taken eight years to master in Time Lord Academy , the Entity could not process this wish and got destabilised . The Doctor described this as the Entity vomiting . Most employees and customers were restored to their natural state and staged a revolt against Chief Security Officer of the theme park , August Hart . ( COMIC : " The Friendly Place " ) But the thought of a time machine awoke the Talent Scout in SERVEYOUinc City , who emerged from the Entity and quickly took control of SERVEYOUinc and the Doctor . ( COMIC : " The Rise and Fall " ) They used the Entity to expand the TARDIS ' s matrix to the whole of the city , but the Entity was hurt by this process and required narratives , stories as food . When the Alice Obiefune helped the Doctor to shake off the Scout ' s control , the Entity got free , destroyed the whole city and ran away in fear . ( COMIC : " The Other Doctor " ) It took control of a Cyberman ship to create an army to defend itself . The ship crashed to Earth in Rome in 312 . There the Entity continued using its ability to give people what they wanted to recruit more soldiers into its army . It also took control of John Jones . The Doctor managed to stop the Entity from taking control of the whole planet by getting it into contact with ARC , through himself . ( COMIC : " Conversion " ) Having absorbed Jones , the Entity decided to run again , this time to the time before there was anything . The Doctor managed to contact it again through ARC and asked Jones to help pacify the Entity . Jones sang to it about love and caring . After that , the Entity fashioned itself into a saucer - shaped timeship and brought Jones back to the Doctor and Alice in Rome . Jones was now in a symbiotic contact with the Entity playing the role of its spokesperson . ARC took the equivalent of the captain ' s seat in the Entity and they have finally reunited . The Entity , ARC and Jones brought the Doctor and Alice to London around 2015 , where the TARDIS ran away to . Soon after the Entity returned to being a free celestial body . The Doctor , Alice and Jones brought the Talent Scout and it was reabsorbed into the Entity . After this , the Entity let Jones go . ( COMIC : " The Comfort of the Good " )
