The HYDRA Buyer was an operative of HYDRA and the Ten Rings. His attempt to buy the Yellowjacket Suit with Mitchell Carson was thwarted when Ant-Man intervened, the buyer was knocked out and later died when Pym Technologies Headquarters was destroyed.
As a member of both HYDRA and the Ten Rings, HYDRA Buyer was contacted by Mitchell Carson who attempted to strike a deal with Darren Cross, in order to obtain the Yellowjacket Suit. The suit, created by Cross Technologies, would provide access to the shrinking technology Carson wanted from Hank Pym decades before. Cross, deranged due to the neurotoxic effects of the Pym Particles, made a deal with Carson and his HYDRA agents: they would kill Pym and pay Cross double for the suit, however, they were interrupted by Hope van Dyne and Scott Lang. He would later die when Pym Technologies Headquarters imploded.
