M.O.D.A.M. appeared to have been the A.I.M. agent S.O.D.A.M. (once believed to have been Maria Trovaya, first wife of Henry Pym) in an upgraded form.[2][3]
M.O.D.A.M. failed at this mission, and was later assigned to retrieve Diamondback, Asp, Anaconda, and Black Mamba for another of A.I.M.'s clients, Superia. M.O.D.A.M. succeeded this time but Superia's plans were thwarted and M.O.D.A.M. was defeated by Captain America.[5]
Later when A.I.M. Island was invaded by Captain America, Falcon and Diamondback, M.O.D.A.M. failed to prevent former client Superia from destroying a Life-Model Decoy of the ruler of A.I.M.[6]
