Unlike the overwhelming majority of its kind, the Venom symbiote developed an attachment to organic life beyond using them as chattel -- with its favorite host having been Eddie Brock, who it kept alive for five-hundred years.
Does Venom make his host immortal? Eddie was able to stay alive as a codex due to the bond he and his symbiote shared, proving that he achieved immortality granted to him by the source of his superhuman abilities, exactly like the Hulk.
He may have been burned and believed he would die, but he was mistaken. Venom only feeds on Eddie's organs when he doesn't get the food he needs (i.e., living things).
Venom is destroyed, but its death is in and of itself an act of creation of the highest magnitude. As Venom's consciousness flickers out, the last thing we see is a memory of Eddie and the other people Venom loved and was willing to destroy itself to preserve.
This rather alarming news is swept under the rug during the finale and by the end of the movie, Venom and Eddie are back together in human-Symbiote bliss, with everyone rather conveniently forgetting that hosting Venom is slowly killing Eddie.
Shortly after, the Gargan version of Venom stumbled across Eddie and the symbiote attempted to bond with Brock again. The leftover symbiote inside Eddie rejected Venom and transformed him to become a stronger force for good.
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.
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.
Eddie Brock is easily the best Venom host, both in the comics and in the mind of Venom itself. Through the years, Venom has proven that he will jump out of a host without a second thought if he has a chance to get back to Eddie Brock (or Peter Parker for that matter).
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.
No, though on a small scale the symbiote can kinda slow the aging process slightly, NOT by ANY means imortally.
Though Venom at first enjoyed his newfound immunities, he left after being abandoned during a dangerous mission. After receiving a head wound, Eddie suffers amnesia. He is later separated from the symbiote, which is presumed killed by the government Overreach Committee.
Venom sacrificed himself to protect his human host from Drake's exploding rocket ship, sending Eddie safely into the San Francisco Bay. The closing moments reveal that Venom survived the blast and is once again bonded with Eddie.
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.
While captive, the Venom symbiote was forced to give birth to five offspring - Riot, Lasher, Phage, Agony, and Scream - who were bonded to PMCs hired by the Life Foundation. When corrupt corporation Scarmore Inc.
Having bonded with the symbiote, the two became the being known as Venom. During this time, it spawned seven offspring and a clone; its first child later had three of its own, producing the symbiotes known as Carnage, Scream, Lasher, Phage, Agony, and Riot.
In the comics, Anne Weying was bonded with Venom, which led her into becoming She-Venom. She was also married to Eddie Brock.
While captive, the Venom symbiote was forced to give birth to five offspring - Riot, Lasher, Phage, Agony, and Scream - who were bonded to PMCs hired by the Life Foundation.
Originating as an offspring of Venom, Carnage is much more powerful than its parent symbiote because of the symbiotes' biology, and is in many ways a darker version of him.
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.
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.
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.
The webbing is pretty strong, but eventually evaporates into dust. But that's not what makes this one of Venom's weakest powers. The fact is, the webbing is a part of Venom and every time he leaves a dusty strand behind, he leaves part of himself behind and depletes his abilities and strength.

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.
