The Life Foundation Venom went through a procedure where multiple "offspring" were created from him—thus Riot, the product of a symbiote spawn and Trevor was born. Unlike the other symbiote hosts, Trevor was extremely aggressive and unsympathetic, far worse than his "siblings" (with the only exception being Carnage).
A doomsday cult called the Life Foundation kidnapped Venom and forced it to produce more spawn. These became the five symbiotes called Scream, Lasher, Riot, Agony, and Phage. Each was bonded to a Life Foundation mercenary and terrorized Venom.
Having bonded with the symbiote, the two became the being known as Venom. During this time, it spawned seven offspring and a clone; its first child later had three of its own, producing the symbiotes known as Carnage, Scream, Lasher, Phage, Agony, and Riot.
Riot is the main antagonist of the 2018 film Venom. was a symbiote originating from Klyntar and an enemy of Venom. At the time of his death, he was bonded with Carlton Drake. He is Venom's older and abusive brother.
The Scream symbiote appears in the Spider-Man series finale "Maximum Venom", voiced by Meg Donnelly. This version is the older sister of the Venom symbiote who was created by Knull to serve as a member of the Symbiote sisters alongside Mania and Scorn.
In the movie, Riot was not a child of Venom but was an alien that arrived on Earth at the same time as Venom. Furthermore, Riot was more equipped for battle and proved to be stronger than Venom every step of the way.
This long-haired offspring of Venom has taken a different path from her siblings, trying to be a hero. However, her origins and journey still include some very villainous moments. Scream was first introduced in 1993 in Venom: Lethal Protector #4 alongside her siblings.
Over time, the symbiote has come to terms with its guilt, which may explain Venom's shift towards the side of good in recent years. Uncle Ben was a prime influence in Spider-man's life–and in turn Spider-Man was Venom's Uncle Ben.
Symbiote consumption: Riot has the ability to absorb any symbiotes, along its host, to bodily achieve much more powerful strength as he was able to absorb Venom and Brock into himself.
Lasher is a largely green and light aqua symbiote. It grants it's host long claws, and instead of boot like feet there are two visible toes. It can manipulate its body into various forms.
Sleeper is another member of the Venom line of symbiotes; the most recent offspring of the Venom symbiote, he is considered siblings with Carnage and the Life Foundation symbiotes (Lasher, Phage, Scream, Agony & Riot).
Venom is also depicted as having spawned several children—Scream, Lasher, Phage, Agony, Riot, Mania, Sleeper, and most notably, Carnage, who becomes Venom's archenemy after being bound to serial killer Cletus Kasady.
Brock later bonds with the Venom symbiote to seek revenge against Spider-Man under the belief that the webslinger ruined his journalism career, only to be defeated and separated.
While we never got to see the original female version of Venom, Eddie Brock's ex Anne Weying did at one point bond with the symbiote to become She-Venom.
Dylan Brock is the son of Eddie Brock, Anne Weying, and the Venom symbiote. When Anne bonded to the Venom symbiote, the will of the Symbiote Hive caused her codex to incarnate into a human form, with the intent of having the ensuing human/symbiote hybrid destroy their god Knull.
Personality. Carnage is a sentient being of pure evil, shown by how moments after the symbiote was born it wreaked havoc in Prison during its escape. Carnage also has a deep hatred for its father, Venom, wanting to kill him so that he could be the only symbiote on the planet and thus unstoppable.
Anne commented on it was nice, only misinterpreted by Eddie about their kiss, but she clarified that it was about the power as Eddie suggested. Anne would also promise Eddie to not tell Dan about their mutual kiss.
Anne Weying first met Eddie Brock while a law student at Empire State University, and fell in love with him after he falsely claimed to have saved her from a group of thugs. Anne and Eddie eventually married, and while he became a journalist for the Daily Globe she became a successful lawyer.
In the present, he attempts to use Eddie Brock to investigate Cletus Kasady, but is seemingly killed during a battle between the Venom and Carnage symbiotes and Barrison. However, he absorbs a piece of one of the symbiotes, which later revives him and causes his eyes to glow blue.
The Toxin symbiote has a long and troubled history in the Marvel universe as both a villain and an anti-hero. Toxin's place in Venom and Carnage's genetic line and its difficulty with hosts have all helped define the symbiote and its ever-expanding place in the Marvel Universe.
The hierarchy of symbiote colors is now established, with red symbiotes being naturally stronger than black ones. The white Anti-Venom is considered one of the strongest symbiotes, further solidifying the hierarchy and establishing its position at the top.
