Meeting Venom
However, after the collapse of S.H.I.E.L.D. he needed Agent Venom’s help because his former allies lost control and became completely bonded with their symbiotes; because of this, the U.S. government was going to dispose of them. He sought out Flash Thompson’s help, but ran into Eddie Brock instead. Strickland offered Brock more knowledge of symbiote history and capabilities in exchange for help finding his former allies.
