Kari Frost, quite a unique name, was born in Leipzig, Germany. She grew up in a boring life being a basic person, as she claims, like a "nobody" or a "grunt". Taking student exchange programs to have schooling in America, Kari was one a few lucky people to try this out, and was dissatisfied by America's lethargy and lack of care of other countries. Instead of doing too much into college, Kari wanted to support her country militantly. Though being a police officer at a questionably young age, she experienced an event which greatly presented her "mind over matter" mindset to an interested few individuals. Eventually, she made her way into Grenzschutzgruppe 9 (GSG-9). Doing so forced her to move to the Federal City of Bonn. While being in GSG-9, she has earned permanent scars of a knife to the left shoulder and a slash down her right arm from a reckless knife fight. When the nasties hit Europe, she and two other operatives lasted a year in the remnants of Germany. Later to be found by Nate, The Anger , and Scully (in that order) Kari set on a plan of escape, which in a pyrrhic victory she had lost her colleagues Marius and Dominic to The Anger's ignorant bloodlust. Ignorant of American life other than the unpleasant life she had in the exchange program, she was left to decide which state to reside in when she and Nate had taken refuge in America. Kari had chosen Florida for it's fairly warm weather and paradise hearsay, to which hesitantly agreed. While living there, Nate had also taken refuge from Aaron due to his immoral actions against Kari.
