Scream

Scream was one of the five Life Foundation Symbiotes that were forcefully spawned from the Venom symbiote. Unlike her "brothers", she wasn't merged into the Hybrid symbiote, ultimately defeated separately by Eddie Brock.

Years later, Scream was resurrected by Knull, still bonded to her original host Donna Diego's corpse. When Patricia Robertson - a soldier who had formerly hosted a clone of the Venom symbiote - attacked it, Scream abandoned Donna's skeleton and bonded to her. Initially having assimilated Donna's personality, Scream succumbed to Knull's control and attacked Andi Benton, who it recognized its host bore a grudge against for having bonded to and lost the cloned symbiote.

Later entrapped and imprisoned by Advanced Idea Mechanics, Scream's prison was unknowingly breached by Inhuman operative Heather Mason, who was attacked by and bonded to the symbiote. Their balance of power remains a delicate one.
