The Life Foundation symbiotes: Scream, Lasher, Phage, Riot, Agony
With Marvel Comics riding high and multiple Spider-Man titles going strong, they decided to give Venom a shot at his own limited series. When Venom: Lethal Protector debuted in 1993, it was Venom's first non-villain role, with Eddie Brock and Peter Parker coming to a truce in New York, leading Brock to high-tail it to San Francisco where he falls in with a bunch of cheery homeless squatters living underneath a park.
That park becomes the target of The Life Foundation, led by Carlton Drake (played by Riz Ahmed in the 2018 film), with an ultimate goal of building high-priced doomsday bunkers for the rich and famous, then selling them to make profit and to control whatever society survives the apocalypse. In looking for a police force to work at this utopia, the foundation has decided volunteers in symbiote costumes would make the best security guards. Already having heard of Carnage, Drake and co. capture Venom and forcibly take five "seeds" from the alien. They rapidly age the symbiotes and pair them to people: Scream (yellow, female), Agony (pink, female), Lasher (green, male), Riot (grey, male) and Phage (orange, male). Venom defeats his lab offspring in their first encounter, and the The Life Foundation revives the five only to have them quit and go rogue. They end up in New York where they seek out Eddie Brock, asking him to help them learn how to control their symbiotes' powers. Brock refuses, and Scream has a psychotic break, seemingly killing the others.
This particular episode is relevant to the Venom film because we know Drake would eventually get to wear the Riot symbiote and fight Venom as the main antagonist in Venom. The other symbiotes seen in the various Venom trailers have distinct colorings that seem to match the line-up of the comic book's symbiote children, but we don't know if Scream, Phage, Lasher, and Agony will eventually make full appearances down the line in other movies, or even get one of their own.
