His symbiote is corrupted and evolved, making Carnage even stronger than both Venom and Spider-Man.
Cletus Kasady
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 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.
Venom's most dangerous offspring became one of Marvel's most vicious villains after bonding with serial killer Cletus Kasady. Carnage is more violent, unpredictable, and some would say more powerful than 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.

The idea that he would become stronger after eating Carnage seems to come from an idea that he would be absorbing Carnage's symbiote powers and properties into himself, therefore becoming stronger. However, unlike the mutant powers of Rogue, Venom is not absorbing Carnage but consuming him.
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.
While in prison, Venom produces an offspring named Carnage. (He reproduces asexually, in case you were wondering.) Venom doesn't tell Eddie about it, and Venom and Eddie escape prison. Once they're gone, Carnage bonds with Cletus.
Symbiotes tend to become more powerful with each generation, and that is why Venom and Carnage were both so fearful of Toxin's potential power.
Riot can transform at an extremely fast speed. He can morph his hands into large weapons of mass destruction and is physically stronger then Venom. That is how he beat Venom in a one on one fight.
After suffering a beatdown at the hands of Shriek, we see Mulligan's eyes glow blue. One likely reason for this, is that a symbiote has been implanted in him…. somehow. In the comics, Detective Patrick Mulligan is host to the third symbiote introduced in Spider-Man lore, Toxin.
And when the Avengers came to stop him, Carnage took over their bodies too. In that way, CARNAGE, U.S.A. seems like a direct forerunner of ABSOLUTE CARNAGE. It was the first time that Carnage was truly a threat on the Avengers' level.
Why is Carnage so powerful? 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.
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.
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.
Blue Symbiote (2) (Agony): In the comics Agony was one of the symbiotes forcibly spawned from Venom alongside several others by the Life Foundation.
Why is a red Venom worse? 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. The reason Carnage is red is because he bonded with Cletus' blood directly just like how it happened in the comics.
Birth. Born from Carnage as the 1000th symbiote in its lineage, "Toxin" was feared to be the strongest and most dangerous of their race by both Carnage and Venom besides Knull. Shortly after being born, the symbiote united with police officer Pat Mulligan.
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.
The first and most well-known symbiote is Venom, who originally attached itself to Spider-Man during the 1985 Secret Wars miniseries. After Spider-Man rejected it upon discovering its true evil nature, the symbiote bonded with his rival, Eddie Brock, with whom it first became Venom.
Carnage was once a serial killer known as Cletus Kasady, and became Carnage after merging with the offspring of the alien symbiote called Venom during a prison breakout. The symbiote amplified his psychotic nature making him even less mentally stable than he had been previously, and therefore even more dangerous.
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.
