Pepper Potts
During his kidnapping and soon to be live execution of President Ellis, he and his Extremis-soldiers were defeated by James Rhodes and Stark using his remote controlled armors. The injured Killaim proclaimed himself "The Mandarin" before getting incinerated by Pepper Potts using a gauntlet and an explosive bullet. His characterization is an amalgamation of Simon Krieger and the character Mallen from the "Extremis" comic miniseries.
