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.
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.
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).
Venom's most recent and current host is Brock's biological son, Dylan. 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.
Riot is stated by Venom to be the strongest and most brutal Symbiote. Through Venom, he had humiliated weaker symbiotes including Venom himself in combat.
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.
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.
However, Riot and Drake host were ultimately thwarted and killed by fellow symbiote Venom and the latter's host, Eddie Brock, who destroyed the rocket the pair intended to use to bring more Symbiotes to take over Earth, incinerating them in the resulting explosion.
Carnage does have more abilities, but was like a rampaging kid and Venom ate it to kill it. Riot was cunning, and was even able to rip Venom from Brock and would have eaten him if Brock didn't rebond with it.
Venom came to empathize with Eddie's status as a "loser", eventually deciding to turn on its own kind and save the Earth from being invaded. The symbiote ultimately agreed to work alongside Eddie as a vigilante, to only hurt bad people despite its own confusion of how it can tell the difference of who is good or bad.
As Eddie lays dying, Venom is able to get back to Eddie and heal him. They then get to the rocket and are able to destroy it. The resulting explosion causes them to fall. Realizing that the explosion will kill Eddie, Venom says goodbye to Eddie and uses himself as shield.
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.
Before that though, he describes Riot as the most brutal and strongest symbiote, and there's plenty of evidence to support this claim in both the comic books and the 2018 movie.
With the help of his symbiotic partner Venom, he discovered that he was pregnant. Venom took it upon himself to protect Eddie and the child growing within him, becoming more cautious and even more protective. Over time, Eddie's belly started to round and expand, giving away his pregnancy to the world.
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.
The Marvel Universe can be a hard place to grow up—especially for kids like Dylan Brock, the son of Eddie Brock. Even though he didn't know his dad for the first half of his life, Dylan endured the horror and chaos of Eddie's adventures as Venom before he reached high school.
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.
In the comics, Anne Weying was bonded with Venom, which led her into becoming She-Venom. She was also married to Eddie Brock, unlike the the movies, where she was engaged with him before breaking up later on.
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.
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.
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.
In the comics, Riot was bonded with a mercenary known as Trevor Cole with the intention of making a team of super soldiers. It was initially considered one of the weaker spawns of Venom but it's physically faster and stronger than its siblings.
