Mitchell Carson attempted to strike a deal with the then CEO of Pym Technologies, Darren Cross, in order to obtain the Yellowjacket Suit. The suit would provide access to the shrinking technology he 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. This was interrupted by Hope van Dyne and the new Ant-Man, Scott Lang. During the confusion, the HYDRA operative was knocked out by Ant-Man and was killed in the explosion of Pym Technologies Headquarters.
- Heckler & Koch P7: The HYDRA Buyer drew this handgun against Hope van Dyne when she managed to take a gun from a security guard during the sell-out of the Yellowjacket Suit, but he was knocked out by Ant-Man before he could use the gun.
- Although a HYDRA operative, the HYDRA Buyer also works for the terrorist group known as the Ten Rings, indicated by the organization's symbol as a tattoo on his neck, just like Jackson Norriss who has one on his wrist.
