Biography
Mar-Vell was a female scientist and a white-skinned member of the alien Kree race. Originally based on the Imperial throneworld of Hala, she was active in the ages-long war between the Kree Empire and the Skrulls. Mar-Vell eventually realized that she had chosen the wrong side in the war, and began taking measures to facilitate the end of the conflict.

Mar-Vell traveled to the planet Earth (Kree designation C-54) where she adopted the human name of Doctor Wendy Lawson. She became involved in a top-secret program for the United States Air Force known as Project Pegasus. Through the military's connections to S.H.I.E.L.D., Lawson acquired the Tesseract, which she kept secured on board her space ship, which she kept cloaked in geonsyncrhonous orbit above Earth. The ship-laboratory, also served as a temporary sanctuary for dozens of Skrull refugees. The Tesseract played a vital role in helping Lawson develop light-speed technology. When the Kree learned of this, they sent Starforce commander Yon-Rogg to Earth to acquire it.
