Venom: Let There Be Carnage finally brings the red bloodthirsty symbiote to the big screen, positioning him as an even more violent villain than the bloodthirsty titular anti-hero. Venom, of course, had his origin slightly changed in the previous movie to accommodate the absence of Spider-Man, but Carnage doesn't exactly have this same problem.

Despite this lack of needing the Webslinger, Carnage's origin will be changed a decent bit compared to his debut in the comics 20 years ago. A cellmate of Eddie Brock's who bonded with a leftover symbiote in the comics, Cletus Kasady gains his powers in a much more hands-on way in Venom 2. Here's how the symbiote serial killer becomes Carnage in the bloodiest way possible.

Carnage's Origin in the Comics

Debuting in The Amazing Spider-Man #344 by David Michelinie and future Image Comics founder Erik Larsen, Carnage was created in anticipation of Eddie Brock/Venom being killed off and was meant to replace him. With that character's growing popularity, however, Marvel decided to keep Eddie around and opted to have Venom become an anti-hero while Carnage was introduced as an unquestionably evil villain with no moral compass.

Carnage's introduction in the comics had him characterized as a sadistic serial killer who was brought to Ryker's Island after being caught following his most recent killing spree. His cellmate was none other than Eddie Brock, who had been brought there following his own recent tenure in villainy. Sometime later, the Venom symbiote returned to bond with Eddie again, allowing him to easily escape. Unknown to Eddie, however, the symbiote leaves behind a small part of itself as an offspring.

The Venom symbiote disregards this offspring, seeing it as useless and insignificant. This turns out to be far from the truth, however, as the red symbiote merges with Cletus Kasady to become Carnage. The duo of Carnage and Kasady is a bond far stronger than that of Eddie and Venom, making the new villain far more powerful than the symbiote's progenitor.

Carnage's Origin in Let There Be Carnage

Woody Harrelson as Cletus Kasady in Venom: Let There Be Carnage

As shown at the end of the first film, Cletus Kasady, like most of his incarnations and adaptations, is a vile serial killer whose loose grip on his homicidal tendencies landed him in the Ravencrofr Institute. Eddie interviews him in an attempt to get his career as a journalist back on track, a feat which the Venom symbiote ironically doesn't make any easier.

Now, in the trailer for Let There Be Carnage, a scene is shown where Kasady bites Brock on the hand, drawing blood out of the unsuspecting journalist. Kasady then states that, while he's sampled many types of blood, Brock's doesn't taste anything like what it should taste like. It would seem that this bloodletting scene is where the symbiote comes into contact with the madman, uniting with him secretly and finally making its presence known when Kasady is to be put to death.

A question is raised, however, in terms of how Kasady could bite Brock without Venom reacting. It will more than likely be explained as Venom actually listening to Brock and not showing up in public without his permission, but it also suggests that Venom is scared of his future red rival even before he gains a symbiote of his own.

To see how Carnage forms, Venom: Let There Be Carnage arrives in theaters Sept. 24.
