He tried to kill couple helpless civilians who were there to meet another inmate called Sentry. Who then intervened and flew Carnage outside of the Earth's atmosphere, where he ripped him apart. Kasady was presumably killed and has not been seen since.
In desperation, Spider-Man made a truce with Venom to fight Carnage. The Carnage symbiote was defeated and apparently destroyed with sonic weaponry, but unbeknownst to them the symbiote's deeper equilibrium with its host helped to save it.
Though Venom ultimately kills Carnage at the end of the story, he's too slow to stop Carnage from awakening Knull and luring the dark god to Earth. That's the foundation for the sequel, 2020's King in Black.
Weaknesses. Like most other Symbiotes, it is vulnerable to sound and fire. However Carnage doesn't mind heat as long as it's the one making it.
In order to defeat the mad symbiote, Spidey usually has to enlist the help of his greatest allies — whether that be the Fantastic Four or his on-again-off-again ally in Venom. Spider-Man does what it takes to stop Carnage, even if it means compromising with villains like Venom.
While Eddie Brock's Venom may not be the strongest here, he is recognizable and the most resilient Symbiote compared to many others. Even though he started out as a pure villain, Brock's Venom showed many heroic traits.
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.
As for the less-likely to return, unfortunately, we can't see a way for Woody Harrelson to return as Cletus Kasady/Carnage, given that the film ended with Venom biting his head off.
Originating as an offspring of Venom, Carnage is much more powerful than its parent symbiote because of the symbiotes' biology, and is in many ways a darker version of him.
He tried to kill couple helpless civilians who were there to meet another inmate called Sentry. Who then intervened and flew Carnage outside of the Earth's atmosphere, where he ripped him apart. Kasady was presumably killed and has not been seen since.
Venom is overpowered by Carnage but provokes Barrison into using her powers to separate Carnage and Kasady. Venom devours Carnage and kills Kasady while the collapsing cathedral crushes Barrison. Later, an alive Mulligan's eyes flash blue, revealing that he somehow absorbed a part of Carnage.
This is the moment at which Eddie and Venom realize that Cletus and Carnage are not bonded; thus, Carnage will be easier to defeat than they initially realized. With assists from Anne and her fiancé, Dan (Reid Scott), Eddie and Venom successfully destroy Cletus and Carnage.
The Venom/Spider-Man feud began years ago due to bad journalism, Spider-Man's heroism, and the mutual hatred of one angry symbiote. Though the Lethal Protector has become an anti-hero since the '90s, Venom is still widely regarded as one of Spider-Man's most well-known and iconic villains.
Dylan Brock is the son of Eddie Brock and Anne Weying. When Anne bonded to the Venom symbiote, she somehow became pregnant with Dylan.
The son of Carnage, Toxin, was believed to be the most powerful symbiote ever created. The raw power of Toxin was so great that he was feared even by the King in Black, Knull, creator and leader of the symbiotes.
Blue Symbiote (2) (Agony): In the comics Agony was one of the symbiotes forcibly spawned from Venom alongside several others by the Life Foundation.
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.
The bond between the Carnage symbiote and Kasady was stronger than the bond between Brock and the Venom symbiote. Cletus Kasady was also a serial killer and thought of as insane. As a result, Carnage is far more violent, powerful, and deadly than Venom.
Likely stemming from his loneliness in prison, Cletus desired Eddie's friendship to make his separation from Shriek (his lover) bearable.
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.
Early on in his career as a "lethal protector," Venom was captured by Carlton Drake's Life Foundation and had five samples of his costume taken and turned into new symbiotes. Four of those symbiotes - Riot, Lasher, Phage and Agony - are grouped together here.
Marvel just rewrote Spider-Man history, revealing that the Venom symbiote was never evil - and it was Peter Parker who played the villain. Venom is one of Spider-Man's most infamous villains, but the original story claiming the alien symbiote was inherently evil isn't the truth.
Some people are completely immune to his Spider-Sense. Venom is known to act without setting off his Spider-Sense. This is because the symbiote acquired all knowledge of Peter's Spider-Sense and adapted to combat it. This immunity extended to Venom's "son" Carnage.
