The Venom symbiote has two major weaknesses - sound and fire. Loud noises cause the symbiote to writhe in pain. That's how Peter Parker originally freed himself of the symbiote. A tolling church bell drove the two apart and sent the fleeing symbiote straight into the arms of an unsuspecting Eddie Brock.
A symbiote is only as strong as the bond that it shares with its host. With that in mind, Venom is the clear winner, having formed a number of strong bonds since making its debut back in issue 252 of The Amazing Spider-Man.
Symbiotes like Venom are immensely powerful, possessed of great strength and endurance, but they also have two extremely common weaknesses: fire and sound. Numerous foes have used these to best Venom and other symbiotes, and Peter Parker even originally repelled the symbiote suit by exposing it to a tolling bell.
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.
The other Celestials then banished Knull, along with the severed Celestial head, deeper into space. After that, he started using the head's cosmic energies as a forge for the symbiotes, which is how they developed the weaknesses to sound and fire.
Venom is a villain in Marvel's Spiderman. He also known as Eddie Brock. He hates Spiderman because he thinks he is the cause of all the bad luck in his life. Venom is bigger and stronger then Spiderman.
The Hybrid Symbiote was considered the strongest of the Venom-spawn created at the Life Foundation. It was created after the Symbiote Scream destroyed the other four Life Foundation creations Phage, Riot, Lasher, and Agony.
It could be that in the universe of the Venom movies, this type of strong bond is already known among the symbiotes to result in stronger specimens. This could explain why Venom is so fearful of facing an enemy with a ruddy hue.
Venom later decided to absorb the Carnage symbiote "for good", during which Kasady retained the Carnage persona by costuming himself in red paint and continuing his killing sprees (albeit as a powerless human).
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.
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.
Venom is completely bulletproof, but he doesn't just deflect the shots like steel. That pliable gel is very reactive and bursts before reshaping to its body. That is probably the reason that the symbiote can heal Brock's human body so quickly.
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.

Venom can't beat Tony Stark. The Iron Man armor is equipped with Venom's two fatal weaknesses; sonic and fire/heat attacks.
Carnage is Venom's offspring and with Klyntar/Symbiotes their offsprings are more powerful than the parent. But Venom bonded himself to Eddie's body down to the cellular level. That way if Eddie gets hurt or something Venom can essentially heal Eddie's injures faster.

Carnage's Symbiote Powers
The symbiote learned from its time bonded with Peter, and it replicates many of his genetic gifts once it bonds with Eddie. That's also why Venom is immune to Peter's Spider-Sense. As you might expect, that makes Carnage stronger than both Spider-Man and Venom.
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.
Blue Symbiote (2) (Agony): In the comics Agony was one of the symbiotes forcibly spawned from Venom alongside several others by the Life Foundation.
In nearly every iteration of Carnage's character, he is the offspring of Venom. The Klyntar, the race of aliens that the symbiotes belong to, reproduce asexually and can transmit their offspring to other hosts.
However, as per the latest update, Venom 3 is set to start production in June 2023. That's somewhat surprising considering the ongoing WGA writers' strike, but presumably, the team is confident about not needing any rewrites.
They rapidly age the symbiotes and pair them to people: Scream (yellow, female), Agony (pink, female), Lasher (green, male), Riot (grey, male) and Phage (orange, male).
Just as Venom is a step beyond Spider-Man in terms of strength, Carnage surpasses Venom in terms of both power and potential for destruction. Carnage was created when Eddie Brock and psychopathic murderer Cletus Kasady were cellmates. When Eddie escaped and left a trace of his symbiote behind, it fused with Kasady.
Venom's origins can be traced to a race of symbiotes from the planet Klyntar. These beings merge with hosts, and the combined entity tends to have a personality based on both the symbiote and the host itself, though sometimes one side or the other tends to dominate.
