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 overarching 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.
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.
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).
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.
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.
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 has 7 offspring all together. First it was Carnage, then the Life Foundation Symbiotes. Scream, Phage, Lasher, Riot, and Agony. Finally there is the Symbiote Sleeper who was the last spawned.
Riot after recombining with Carlton Drake and immediately stabbing Eddie Brock. You are NOTHING!!! Riot's last words to Venom before being killed alongside Drake by the rocket's explosion when Venom uses Riot's arm blade (which Riot immediately stabbed him earlier) to puncture the fuel tanks of the rocket.
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.
Riot was sliced to pieces by Sleeper, incapacitating the symbiote and killing its host, and was subsequently placed into containment at Alchemax's astrobiology lab alongside Phage, Lasher, and the other captured symbiotes.
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.
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.
According to symbiote biology it would be The All-Black, also known as The Necrosword. Due to being the first symbiote knull ever made, it's already weak as it is, only granting the basic suit and itself as a weapon.
"The Nativity" arc in Venom #164 features the alien symbiote becoming "pregnant" and giving birth to the Sleeper symbiote, resulting in Eddie Brock having vivid nightmares and experiencing symptoms similar to an expectant parent.
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.
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.
Extremely loud sounds (or extremely high frequency sound waves) can shock the symbiote, and even cause him to separate from his host. Spider-Man discovered this not long after meeting Venom.
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).
The Riot Symbiote eventually bonded with Life Foundation CEO Carlton Drake with the goal of bringing more Symbiotes to Earth to bond with humans and then take over the planet. Riot and Drake were defeated by Eddie Brock and Venom.
