Venom decided that, in order to completely remove the threat of Carnage from the world, he would have to devour and absorb Carnage completely. Venom managed to remove the Carnage
After saving Kasady, Carnage forms an alliance with him to kill Brock and Venom. Due to their bond being incomplete however, Carnage and Kasady are defeated, with the former being eaten by Venom.
Did Venom gain anything from eating Carnage? Carnage barely put up a fight. Pieces of the symbiote were on him, but he didn't fully transform or try to defend himself. Venom simply pulled the symbiote off of him and ate it, becoming stronger.
Briefly retracting Venom from his face, Eddie apologized to Cletus before Venom angrily devoured the serial killer's head and contemptuously tossed his corpse aside.
Carnage is a psychopath. Venom also, at times, does not want the symbiote to spread, and has actively hunted down other symbiotes. And to build on what you are saying, Venom also feels responsible for Carnage. That's why Venom always tries to be an active character when Carnage is on the loose.
In addition, Venom has come out on top as the victor in many battles with Symbiotes like Carnage, Hybrid, and Scream (all of which are arguably more powerful than he is).
In the trailer, the Venom symbiote expressed reluctance about fighting him after noticing that Carnage is a “red one,” which suggests that red symbiotes are naturally more powerful than all other members of his species.
When a symbiote offspring of Eddie Brock, AKA Venom, merges with serial killer Cletus Kasady, the result is the nightmarish murdering menace known as Carnage! Reborn from an alien creature, he's a more psychotic and dangerous being that spawns a family of symbiotes.
During the last interview with Brock, Kasady started mocking the reporter by wishing him a heartbreak for uncovering his secrets. Venom wasn't satisfied with his actions and attacked the prisoner, which resulted in Cletus bitting Eddie's hand. Right after the bite, Carnage was born and bonded with its host.
Who would win in a fight between carnage and riot? 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.
During the fight, Mulligan is apparently killed by Barrison, but absorbs a piece of one of the symbiotes, which later revives him and causes his eyes to glow blue.
Without a doubt, "The Nativity" arc (by Mike Costa and Mark Bagley) is among Venom's most unusual stories, featuring the alien symbiote becoming "pregnant" (while Eddie Brock was his host) and giving birth to the Sleeper symbiote.
Carnage is Venom's son. Like most organic beings, Venom's race known as the Klyntar also reproduces and creates other symbiotes. Venom spawned an offspring while he was rescuing Eddie Brock from prison. The newborn symbiote bonded with Eddie's cellmate Cletus Kasady and became Carnage.
When it comes to sheer brute strength, Carnage is very much stronger than his sire Venom. The primary reason for this is that each evolution of the symbiote is stronger than the last and also because Carnage bonded with a human whose psychotic and unhinged personality traits were amplified.
Feeling shunned, the symbiote bonds with Eddie Brock, as the pair become Venom through their shared hatred of both Peter Parker and Spider-Man. In simple terms, Venom hates Spider-man because Peter Parker rejects the Symbiote.
The spawn of the Venom symbiote then attached itself to Kasady through his bloodstream. Carnage achieves this by entering Kasady's body through a cut on his hand. This is the reason why Carnage appears as the colour red, as he entered through the bloodstream, which is of course red.
As you may recall from the first Venom movie, the symbiote was unable to bond with numerous people and left each of its test hosts dead. It wasn't until Venom formed a special bond with Eddie that both the host and symbiote were able to survive.
In Venom 2, Carnage addresses Venom as “father” at the beginning of their climactic final showdown.
The 2003 story "The Hunger" introduced new elements to Brock's origin, revealing that Brock had cancer before joining with the symbiote, and that it chose to bond with Brock not only for his hatred towards Spider-Man, but also because the cancer causes the release of adrenaline, which feeds the symbiote.
The original Carnage symbiote was the first offspring of the Venom symbiote, spawned when it broke Eddie Brock out of prison. The newborn symbiote bonded to serial killer Cletus Kasady, merging with his blood to become nigh-inseparable from him, and Carnage was born.
Because Kasady is a deranged serial killer, they share a sadistic personality and their bond is stronger than that between Venom and Eddie, and Carnage increases Kasady's violent tendencies. Carnage, then, is more powerful, violent, and thus deadly than Venom, and became his archenemy in the comics.
Dylan Brock is the son of Eddie Brock and Anne Weying. When Anne bonded to the Venom symbiote, she somehow became pregnant with Dylan.
Blue Symbiote (2) (Agony): In the comics Agony was one of the symbiotes forcibly spawned from Venom alongside several others by the Life Foundation.
Venom 3 was originally expected to arrive sometime in October 2024, but the fact that Sony has moved it up on the schedule suggests that they are confident about delivering the film despite the impact of the WGA and SAG-AFTRA strikes on the production (more on that below).
Part of establishing this is portraying Venom himself as being as afraid of Carnage as audiences may be. When Eddie and Venom first see the symbiote-covered Kasady, Venom for some reason immediately turns tail and flees in fear.
