History
Mandarin shared a similar history to his Earth-616 counterpart until after Project Communion were kidnapped and Clint Barton and Kate split as partners over a disagreement on rescuing them. 30 years later Project Communion resurfaced, and killed thousands in an explosion in China and made it seem as though the Mandarin was to blame. Clint was recruited by Kate to help fix their mistake from the past and donned a new suit. The pair traveled to China but were captured by the Mandarin and brought to his castle.
While imprisoned Kate realized that S.H.I.E.L.D. set them up to be killed for being the only two people that would know that it was S.H.I.E.L.D. that unleashed Project Communion on China. During a meeting with the Mandarin he revealed he had one of Project Communion captured and wanted the pair to show him how to use it to exact his revenge. Kate, however, called in Marvel Boy who helped them escape, holding off the Mandarin.[1]
