However Carnage doesn't mind heat as long as it's the one making it. After being exposed to the eldritch power of the Darkhold, the symbiote has lost its vulnerability to sonics, though it is still vulnerable to heat and has gained a vulnerability to Chthonic magic.
After Adrian Toomes injects Peter Parker with a makeshift symbiote sample, he transforms into Carnage and breaks free, going on a rampage throughout the Trask building until he is defeated by Venom, who absorbs the symbiote from Peter's body.
The realization helps lift Venom's spirits, and Eddie's confirmation that the two of them indeed are lethal protectors gives them the strength to lift the rubble and fight Carnage one last time. Venom takes a metal bar and climbs the church, stabbing Carnage in the head and freeing Anne.
Sonic Immunity: Though it used to be weakened by them, Carnage has become immune to sound-based attacks after he came into contact with the Darkhold.
3/15 Toxin
Toxin has the same powers and abilities as Venom and Carnage, but is stronger than both combined.
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.
While teaming up with Spider-Man often leads to the Carnage's defeat, Venom doesn't really stand a chance on his own. Carnage was born from Venom's symbiote, and he is simply stronger, faster and more durable than his "father." Venom nevertheless tries to fight Carnage time and time again.
The reason for this is that Carnage is a "red one," as Venom states, which is apparently quite concerning. Venom refuses to emerge from Eddie's body again, clearly scared of his vermilion enemy.
After a massive showdown at the end of Venom: Let There Be Carnage, Venom defeats Carnage and eats him - but some viewers have wondered if the consumption will have any impact on Venom's strength. Comic book enthusiasts were clamoring for the on-screen face-off between the symbiotes, and the movie didn't disappoint.
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.
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.
Cletus was enraged upon learning that Eddie's exposé had gotten him sentenced for execution and Eddie was his first target after he bonded with Carnage. Eddie was also remorseful for the way he hurt Cletus, as he apologized to him in the climax for disregarding his inner pain.
Blue Symbiote (2) (Agony): In the comics Agony was one of the symbiotes forcibly spawned from Venom alongside several others by the Life Foundation.
Both Venom and Carnage feared the potential power of Toxin, establishing him as a force to be reckoned with. The character was created by writer Peter Milligan and artist Clayton Crain.
The Venom symbiote eventually found Eddie and reunited with him, unknowingly leaving behind its offspring. This offspring eventually bonded to Kasady's blood through a small cut, making the Carnage symbiote have its red appearance, which resulted in Carnage being more powerful than Venom.
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.
The Carnage Symbiote is the fourth Pure Evil villain to appear in a Spider-Man film, following Carlton Drake, Riot and Mysterio.
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.
Knull, also known as the God of the Symbiotes, is one of the overarching antagonists in the Marvel Comics universe, serving as the main antagonist of the Venom comic book series.
These were cultured and bonded to five of the Life Foundation's best security personnel to form the Guardians: Donna Diego (Scream), Carl Mach (Phage), Leslie Gesneria (Agony), Trevor Cole (Riot), and Ramon Hernandez (Lasher). In the comics none of the five symbiotes were originally given names.
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.
