Brent Cleever

Brent Cleever, better known as Twenty One, was a Senior Special Agent for the Universal Secret Service.

Early life
Cleever was born in Kahra in 2018 to parents who were early colonisers of Mars, having arrived there in the early part of the 21st century. After leaving Kahra University with a degree in commercial management and salesmanship, he began work with the Kahra International Toy Company.

On his first representative trip to Venus, Cleever was involved in the breaking up of the Organisation For Liquidation, Extermination, Terrorism and Arson. As a result of this, he was approached by S, the head of the newly formed Universal Secret Service. (PROSE: This is 2065)

In the USS
News from Washington once indicated that sixty agents from the Marine Commando Division had been dispatched to Triton to give aid to Agent 23, who was searching for the missing Agent 21. (COMIC: Plague of Death)

In December 2046, after the failiure of Senior Special Agent 24, S told Twenty One to go to Great Britain in order to overthrow the Director, the head of a military dictatorship, so that Britain would be permitted to join the World Government. Although he and Agent Tina Palamac were initially forced to swim four miles to Wales when the World Navy submarine they were aboard was attacked, Twenty One and Tina were able to work with the revolutionaries to uncover a traitor within their midsts and blow up the Director's palace in London by using a toy aircraft loaded with atomic bombs.

Two months later, in February 2047, Twenty One was with Dai when World President Nikita Bandranaik officially welcomed Britain to the World Government. (COMIC: Down With The Director)

By 2065, Twenty One was in charge of field agents and the administrative control of the USS. (PROSE: This is 2065)

TV 21 once printed a secret bulletin in their magazine, acting on orders from Twenty One. (COMIC: Duel of the Daleks)

Recieving plans on how to build model Daleks from Agent Howard Whitehead, Twenty One told him that he liked his ideas and that HQ staff had already built some and were planning a mock battle with models of the World Government Army. He further commended him by stating that he had brains and was sure he would be able to devise a means of escape if ever in a tight spot. (PROSE: From Howard Whitehead)

Twenty One informed Agent Peter Ayliffe that Agent 0031, who had been assigned to take Ayliffe's recently-invented Identicode to the Dalek Emperor, had not been heard from since. (PROSE: From Special Agent Peter Ayliffe)

Twenty One explained to aspiring agent Derek Connell how reports from the Stingray and XL5 teams were relayed to Earth so quickly. Working on the same principle as television, radio waves carrying the pictures were fed through a special wave accelerator which boosted their speed to faster than that of light. (PROSE: From D. Connell of Essex)

After obtaining a guarantee of safety from David Corley intended for the Kaplan Minus which invited him to Essex, Twenty One revealed to him that the guarantee had been recieved after Steve Zodiac left for Astra and, as the Minus was now dead, he assured Corley that it would be given to the new Kaplan instead. (PROSE: From D. Corley)

Twenty One replied to Agent R. Miles, who had made a spy game and enclosed it in a letter, suggesting that a similar game be given away as a prize. He gave Miles details about the TV Century 21 Summer Extra which HQ staff did indeed devise a spy game for. (PROSE: From R. Miles)

Philip Bevan sent Twenty One a letter about his theories on the anatomy of the Dalek that also told him about his weekly comic, Thriller. Twenty One replied, telling Bevan that he was interested in seeing a copy of the publication at some point. (PROSE: From Philip Bevan)

When Agent J. Gray wrote in to answer Agent Connell's question about the identity of Lady Penelope, they stated that "by secret detection" they had discovered that she had applied for a job as a part owner of an emergency rescue service. Twenty One confirmed the authenticity of this intelligence, adding that she would be joining the Tracy brothers and "their fantastic crafts" in Thunderbirds later in the year. (PROSE: J. Gray)

Agent E. Oglesby contacted Twenty One with an inventory of the special tools in their possession after Twenty One had done the same. He told Oglesby that they had presented a "good report" and that agents should always take care of their equipment, among which was the Dalekode, because "they never know when they might need it". (PROSE: E. Oglesby)

When Agent 671107 contacted Twenty One concerned that they were being observed by enemy agents, he told them that there were no Senior Agents currently assigned to their area but noted the possibility that these suspected enemies were just some junior agents practising. (PROSE: From Agent 671107)

Responding to a photograph sent in by Agent R. J. Landen of a replica of Dr. Who's time machine that they had created, Twenty One said that it was a "fine piece of work" and was certain that other agents would wish to see it. (PROSE: Agent Inventor)

In 2066, Twenty One complimented Agent Mason on their report about Zeg, which identified the Red Dalek in the week's password, stating that they were "obviously a keen follower" of the Daleks' story. (PROSE: Password Report on Red Dalek)
