Brent Cleever

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)

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)
