Gregory Bryan had been turned into the new Sidewinder by the Brand Corporation under the orders of Hugh Jones and was a member of the Serpent Society. After Gregory left, Cobra used the Brand Corporation's equipment (which had been long stolen by the Serpent Society) to create more Sidewinders. Upon being improved, Sidewinder later sprung the other Serpent Society members from their cells. After the group had captured and chained Captain America and Diamondback (who was really an L.M.D.) in this underground New York headquarters, the pair escaped. Sidewinder was knocked out by "Diamondback". S.H.I.E.L.D. subsequently took Sidewinder and the rest of the Society into custody.
