Constituent-Matter Manipulation (Blunt Weapons): Unlike his fellow symbiotes, Riot's symbiote preferred to create large bludgeoning weapons like hammers and maces from his arms. This was presumably caused by Trevor's aggressive mentality.
Trevor was a volunteer/mercenary for the sinister Life Foundation, an organization that was preparing for the M.A.D.(Mutually Assured Destruction) fallout of the Cold War and sought to provide a comfortable life for their wealthy clients after the impending nuclear holocaust. Trevor was picked from the organization's security force made up of cops, soldiers, and mercenaries to take part in an experiment.
Once the Life Foundation had captured Venom, who was in San Francisco at the time, they brought him to their lab in Mojave Desert California. There, they forcibly extracted five ďseedsĒ from Venom and hatched them to give rise to a yellow-and-red symbiote, a green symbiote, a dark grey symbiote, a yellow-and-black symbiote, and a purple symbiote. Trevor played host to the dark grey symbiote. Together the dark grey symbiote and Cole along with the other four hosts, would become the Life Foundation's Guardian Symbiotes. Unlike the other symbiote hosts, Trevor was extremely aggressive and unsympathetic, far worse than his "siblings" (with the only exception being Carnage.)
