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.
While being in Peter's presence, Venom grew attached to him and did everything in his power to bond with Peter. Despite everything Peter has gone through to get rid of the symbiote, it still considers Peter the perfect host.
In Mike Costa and Mark Bagley's once aptly titled 2018 comic book series, Venom: First Host, it is revealed that the symbiote was once a captive of the Kree and bonded to soldier Tel-Kar for use as a super-soldier in the Kree-Skrull War.
Eddie Brock may have started life as a disgraced journalist, but he's gone to become Venom's longest-standing and most powerful host. Marvel tends to shy away from redeeming villains. However, Brock is the exception. He's taken on nearly as many foes as Spider-Man, trouncing them all.
The Scream symbiote appears in the Spider-Man series finale "Maximum Venom", voiced by Meg Donnelly. This version is the older sister of the Venom symbiote who was created by Knull to serve as a member of the Symbiote sisters alongside Mania and Scorn.
Venom came to empathize with Eddie's status as a "loser", eventually deciding to turn on its own kind and save the Earth from being invaded. The symbiote ultimately agreed to work alongside Eddie as a vigilante, to only hurt bad people despite its own confusion of how it can tell the difference of who is good or bad.
The Venom symbiote's animosity toward Spider-Man stems from its initial bond with him. In the comics, Spider-Man rejected the symbiote when he realized it was trying to permanently bond with him, and he removed it. This rejection left the symbiote with a strong sense of betrayal and anger.
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.
Basically, the symbiote didn't attempted to talk with Peter because it wanted to remain loyal and obedient like a servant. It didn't felt the need to talk to him, only to serve him.
The symbiote in turn would develop a hatred for both Kraven and Miles Morales for separating it from Peter as well. Likewise, when both the symbiote and Harry reunite and bond with each other, their inner wrath and hatred allowed them to perfectly fuse together into the being known as Venom.
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.
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 a flashback, it is revealed that she got pregnant with Eddie's child after bonding to Venom. After giving birth to their son Dylan, she left him in the care of Carl Brock, with the promise that she would return eventually. She instead committed suicide, after which Carl raised Dylan.
As you may recall from the first Venom movie, the symbiote was unable to bond with numerous people and left each of its test hosts dead. It wasn't until Venom formed a special bond with Eddie that both the host and symbiote were able to survive.
This long-haired offspring of Venom has taken a different path from her siblings, trying to be a hero. However, her origins and journey still include some very villainous moments. Scream was first introduced in 1993 in Venom: Lethal Protector #4 alongside her siblings.
While we never got to see the original female version of Venom, Eddie Brock's ex Anne Weying did at one point bond with the symbiote to become She-Venom.
Carnage. Easily the most ruthless and dangerous of all of Marvel's Earth-based symbiotes, Carnage has been plagued since its inception by the evil of its first host, notorious serial killer Cletus Kasady.
Perhaps the Marvel Universe's deadliest symbiote, Carnage debuted in AMAZING SPIDER-MAN (1963) #345. Shortly after spawning from Venom, the Carnage symbiote bonded to a serial killer named Cletus Kasady.
The hierarchy of symbiote colors is now established, with red symbiotes being naturally stronger than black ones. The white Anti-Venom is considered one of the strongest symbiotes, further solidifying the hierarchy and establishing its position at the top.
