As the years passed Maya's breakthrough research afforded her the ability to work on the development of the next Super-Soldier formula, which a generation ago had created Captain America. Her approach was to exploit the genetic potential of man through nano-tech and in this vain she eventually developed Extremis.
Extremis was meant to "hack" into the body's repair center and recode the human genes with a more advanced version, leaving the host with improved organs and super powers.
When she learned that she was going to lose funding, Maya came up with the idea that if she could get a test subject to fight and conquer Iron Man, she would be able to prove it's potential. It was with this logic that she stole Extremis and put it into the hands of terrorists, who quickly injected, Mallen one of their own. As the next step in her plan, she contacted Tony Stark feigning distress to ultimately maneuver him into a confrontation with the Extremis-enhanced terrorist."
Iron Man 3 was released May 3rd, 2013 and stars Robert Downey Jr., Gwyneth Paltrow, Don Cheadle, Guy Pearce, Rebecca Hall, Jon Favreau, Ben Kingsley, James Badge Dale. The film is directed by Shane Black.
