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
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)

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)
