After Clint Barton made the decision not to eliminate KGB assassin Natasha Romanoff, but rather recruit her for S.H.I.E.L.D., the two formed a partnership due to their unique and incredible skill set. They would then proceed to go on a mission to Abidjan, Ivory Coast called the Abidjan Operation, as well as various other missions, including at least another to Budapest, Hungary.
