After emerging from the Entity, the Talent Scout could create a life-force enhancement field that gave people what they wanted. The process required their agreement, after which he could take complete control over them, in which case they started emitting a shining golden glow from their eyes and mouths. Such an enhancement would burn out their internal organs, causing premature death, if not reversed. The effects could be reversed by sounds using a correct reverse reprogramming frequency, with headache as the only remaining side effect. (COMIC: What He Wants...)
He could also assume shapes of different people including those, images of which he read from his victims' minds. In particular, at different times he was posing as the mothers of Alice Obiefune (COMIC: The Eternal Dogfight) and of the Doctor. (COMIC: The Comfort of the Good)
Working as a chief scout for SERVEYOUinc, he led a team onto a celestial body, which was a single telepathic Entity. The Entity was the size of the Moon and was situated in a "backwater zone of space". The chief scout's task was to find out if SERVEYOUinc could use the Entity in any way. He claimed he could feel that the organism wanted to learn and sadistically instructed his team to electrocute it because he wanted to hear it scream.
As a reaction to the pain, the Entity sucked in the Talent Scout. He was trapped and remained comatose within the Entity. He was presumed dead by his team and and the Entity with him inside was transported to SERVEYOUinc City. (COMIC: Four Dimensions)
After more than a decade, the Eleventh Doctor's thoughts of a time machine, which were read by a piece of the Entity on Rokhandi, (COMIC: The Friendly Place) woke the Talent Scout in the main portion of the Entity in SERVEYOUinc City.
The Scout killed the SERVEYOUinc's CEO, Enoch Thorne. When the Doctor arrived to talk to Thorne, the Scout, having learned through the Entity what the Doctor wanted, tempted him with the ability to keep people around him completely safe and made him the Chief Executive Officer of SERVEYOUinc. This was the first time the Scout met the Doctor. (COMIC: The Rise and Fall)
The Scout served as the new CEO's closest adviser. When Alice Obiefune helped the Doctor shake off the Scout's control, which ended in the destruction of SERVEYOUinc City, the Scout hid away in the Doctor's TARDIS. (COMIC: The Other Doctor)
When a potential temporal paradox caused the TARDIS to eject the Doctor into space in a non-corporeal form, the Talent Scout tried to tempt each of the Doctor's companions but failed. Alice and ARC threw him out the TARDIS doors and into space. But he promised to return. (COMIC: Four Dimensions)
In 1931 Mississippi Delta, the Talent Scout was offering people to give them whatever talent they wanted turning them into a mindless mob with a golden glow coming out of their eyes and mouths. For the second time in two meetings, he managed to coerce the Doctor into joining his ranks. However, Alice, John Jones and Robert Johnson managed to get the upper hand by using the data from the Doctor's sonic screwdriver, pimped-up Bessie and TARDIS as an amplifier. The Talent Scout exploded but was not destroyed. (COMIC: What He Wants...)
While the Doctor and his companions were involved in the Amstron-J'arrodic airfight, the Scout disguised himself as Alice's mother and attempted to acquaint himself with them. After the Doctor deduced he wasn't Alice's mother, the Scout disappeared after telling the Doctor they'd meet again. (COMIC: The Eternal Dogfight / The Infinite Astronaut)
When the TARDIS got disappointed in the Doctor, she found and gave herself to the nearest Time Lord she could find, to the Talent Scout. When the Doctor managed to get to the TARDIS in London around 2015, the Scout met him in the form of the Doctor's mother and made the TARDIS kick the Doctor out.
While the Scout was nursing dreams of cosmic empires inside the TARDIS, John Jones, ARC and Alice helped the Doctor take back the control of the TARDIS. They brought the Talent Scout to the Entity, again a free celestial body in space. ARC and Jones decided to call him Dave and tempted him to think about what he wanted. As he did so, the Entity reabsorbed him. He was given his own space within the Entity to dream about his success forever. (COMIC: The Comfort of the Good)
