Margaret "Maggie" Powers, a graduate of Oxford University , joined MI6. After some time spent as a researcher, she became a full agent with authority over other departments. According to reports, Maggie was working at the British Embassy, tracking terrorists, including theProvitional Irish Republican Army.
As one of the trusted partners of Gabe Logan, Maggie agreed to help him find a Syphon Filter traffic in Ireland. They were able to sink the SS Lorelei in transit to their destination, but half of Maggie's MI6 team was killed, and Logan killed spy named Nigel Cummings. Later, Agent Powers helped Lian Xing in Australia, in which both captured Dr. Elsa Weissenger.
Logan called her again after outbreaks of The Omega Strain, as he needed the help of European intelligence agencies to monitor the activities of Nikolai Jandran. Eventually, Maggie asked for help from the IPCA when Jandran left his laboratory to extract the virus from the wreckage of SS Lorelei. She provided the Agency personnel with weapons as well as audio-visual equipment, the latter of which was supposed to be planted inside Jandran's labs. Later, video footage showed proof that the virus was being extracted from the North Atlantic.
Later, she would be trying to acquire the X-Z-2 bomb for Great Britain, encountering Logan in the process and helping escape from a Russian gulag. However, Robert Cordell had her arrested after deciding that she was interfering in his pursuit of the same device.
