Hybrid's History
Hybrid is the amalgamation of four of the Life Foundation Symbiotes (Riot, Phage, Lasher, and Agony), whose hosts were killed by Scream, into a single symbiote entity. The fused symbiote then sought out Scott Washington, who was a Guardsman at the Vault (the prison for supervillains) lab facility. While guarding the symbiotes, they escaped their containment field and temporarily bonded with him. It was then that he realized that they were not evil, not a threat, and the experiments were causing them terrible pain, so he let them go when he had the chance. When the Hybrid symbiote located and bonded with him, he regained the ability to walk, and more. Scott has a lot of anger, so often the symbiote would hold him back from acts of violence, not the other way around. Since his symbiote was originally four different entities, Scott had to contend with four different voices / personalities in his head besides his own.
When Eddie Brock started his hunt for symbiotes, he first targeted Hybrid. While Washington was patrolling the streets of his neighborhood, Brock paralyzed him with an electric discharge. A confused Hybrid asked why Brock was attacking him, and although he knew Scott was a hero, Brock shot and killed him. Hybrid was found by the U.S. Army, who separated it into the original four symbiotes and bonded them to each one of the Mercury Team in order to fight Carnage.
After the human members of Mercury Team were killed by Carnage, the four symbiotes bonded to Deadpool in order to take revenge on their "brother." After Carnage and his ally Shriek were defeated, Deadpool passed the amalgamated symbiotes to the dog Lasher.
The dog started wandering the state until it came across a young girl named Sadie, who was crying over her family. The dog comforted her and Sadie invited it inside where, in response to Sadie's wish for a way for her family to stay together, the symbiotes separated and took over Sadie's parents, her brother Billy, and finally Sadie herself. After the family members were separated from the symbiotes by the Maker, they were being kept in the test tubes. They broke out and bonded to the Maker, who then begun attacking Dylan Brock.
While Hybrid was distracted by the arrival of Spider-Man, Captain America, and the Thing, Dylan freed the Sleeper symbiote and seized control of it using his symbiote-powers. Doused in napalm by Sleeper, Hybrid was subsequently set ablaze by Hawkeye; though the Maker managed to escape the inferno and flee into the sewers.
The four Life Foundation symbiotes survived and recovered, still in the thrall of Knull, and when he arrived on Earth they were once again sent to hunt for Dylan Brock. Coming across Scream, now bonded to Andi Benton, the four symbiotes merged into Hybrid and attempted to assimilate their estranged sister, but were blown apart by Scream's Hell-Mark. While Andi assumed she'd killed Hybrid, the gestalt symbiote surreptitiously reformed and escaped into the sewers.
