Major Shepard is First Officer of The Phoenix, and sister to Colonel John Shepard (Military COmmander, Atlantis Expedition). Mikhayla was born to a wealthy family and was the daughter of Patrick Sheppard, a utilities mogul. From the age of six, Mikhayla wanted to follow in the footstpes of her older brother and join the United States Air Force. After her education at Princeton, she entered the Air Force Academy and upon graduation, participated in several top secret missions, particularly in Operation Enduring
Freedom in Afghanistan, but also visited every continent, apart from Antarctica. She trained to become a pilot, primarily the F-16 fighter, F-15 Fighter, and F-22 Fighter. Dedicated (and some say married) to her career, Mikhayla rose through the ranks, and eventually was assigned to Stargate Command, as a fighter pilot. Mikhayla distinguished herself as a pilot during the attempted invasion of the System Lord, Anubis, and earned herself Ace status for shooting down 5 Death Gliders in the air battle over Antarctica. Shortly after, she was assigned to the USS Prometheus, where she continued to serve with distinction. Upon its commissioning, Mikhayla was assigned to the USS Daedalus, as it’s CAG (Commander Air Group), which allowed her to make multiple visits to her brother, John, when the Daedalus was detached to Atlantis. She continued to serve in that position aboard Daedalus up through the formation of the Grand Alliance and the Unification of Earth and it’s militaries into the Earth Defense Directorate.
It was her brother who recommended she apply for a position among the crew of the Phoenix, and Mikhayla was surprised not only to be chosen as one of the Phoenix’s officers, but as the ships First Officer.
