Chloe Blake was born in 1981 and was born in Dover, Kent. She is a middle size person and has brown hair. She is an ex-CHERUB.

During 'The Killing' she is an assistant mission controller of John Jones, but later gets turned into a mission controller herself during 'The Killing', ( due to an outstanding performance during an extremely complex mission.) and is given an assistant, who was also an ex-CHERUB, called Maureen.

However, in 'Mad Dogs' She is criticised for her performance as a mission controller when Gabrielle gets stabbed by a Runt, nearly killing her. But she later improves the overall view of the mission when James and Bruce join, along with the fact that the mission turns out to be an overall success.
