Carnage was once a serial killer known as
Like Venom, Carnage has had multiple hosts over the years, but its most infamous one remains its first - killer Cletus Kasady, whose sadistic personality perfectly matches that of the symbiote.
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.
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.
By eating Carnage, Venom is effectively returning his spawn back to his former "unborn" state within Venom's mass, not taking anything he didn't already have into his cells.
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.
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.
Carnage is “born” when Cletus' execution fails, rushing to protect his host from death. Later in the film at Cletus and Frances' wedding, Venom arrives and Carnage recognizes him as his father.
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.
Carl Brock's appearance in Amazing Spider-Man #375 depicts him with a full head of hair, but Venom: Dark Origin and subsequent appearances depict him as a balding man with a moustache. Venom Vol. 4 shows him as balding in the present, but with a full head of hair in flashbacks to Eddie's youth.
Dylan Brock is the son of Eddie Brock and Anne Weying. When Anne bonded to the Venom symbiote, she somehow became pregnant with Dylan. He was created by the symbiotes in order to destroy their god Knull and sever him from the hive-mind.
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.
One of the most tragic and weirdest Venom stories is how the symbiote made Eddie Brock pregnant, and this pregnancy created more chaos than Carange.

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.
Marvel Comics' new version of Venom has become the most powerful symbiote ever. Dylan Brock, the son of the original Venom host, Eddie, has unlocked a new power that allows him to sever a symbiote's connection to the hive mind, which makes him a threat even for the all-powerful Kings in Black.
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.
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.
Eddie Brock and Venom's next adventure has now been confirmed. Prepare for the return of washed-up journalist Eddie Brock (Tom Hardy) and his symbiote bestie on the big screen: Venom 3 is hurtling towards a 2024 release date.
Venom went through a procedure where multiple "offspring" were created from him—thus Riot, the product of a symbiote spawn and Trevor was born. Unlike the other symbiote hosts, Trevor was extremely aggressive and unsympathetic, far worse than his "siblings" (with the only exception being Carnage).
Venom's most recent and current host is Brock's biological son, Dylan. Venom is also depicted as having spawned several children—Scream, Lasher, Phage, Agony, Riot, Mania, Sleeper, and most notably, Carnage, who becomes Venom's archenemy after being bound to serial killer Cletus Kasady.
they can reproduce asexually with a limited number of seeds inside their mass. For example, Venom gave birth to seven "children", and its first child Carnage had three. senses that extend over its entire surface, enabling hosts to "see" what is behind them or otherwise not in their line of sight (like a Spider-Sense).
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.
Carnage Has Superior Abilities
The character is actually a lot stronger than Venom, despite having been born from him. In fact, Carnage's strength is more forceful than both Venom and Spider-Man's. Carnage can lift more, punch harder and jump higher than his competition.
Woody Harrelson portrays Cletus Kasady in the live-action Sony's Spider-Man Universe (SSU) films Venom (2018) and Venom: Let There Be Carnage (2021), bonding with Carnage in the latter film. In 2009, the Cletus Kasady version of Carnage was ranked as IGN's 90th-greatest comic book villain of all time.
