Sadly, yes. Even though this is the “best” symbiotic human relationship Venom has found, Venom's habitation of a human body is fatal. The only person (or persons) he could habitate in the Marvel universe had to have continual healing factors.
Personality. 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.
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.
While held captive, Eddie was saved by the symbiote and planned to stop Drake, who became bonded with another symbiote, Riot. Once they defeated Riot and expose the Life Foundation for their crimes, Eddie decided to bond with the symbiote, together becoming known as Venom.
Cancer and post-Venom
Brock is left reliant on the suit to live, and pursues Spider-Man out of fear that he will take the symbiote back, rather than for revenge over his lost career. Brock dies after the symbiote leaves him for Spider-Man, not wanting a diseased host.
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.
Venom has the power to heal himself, which makes him a worthy foe, even to Spider-Man. But more than that, he has the power to heal and regenerate his host. This allowed him to heal Flash from being impaled, and for Eddie Brock, it meant he could heal and regenerate to slow or cure his cancer.
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).
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.
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 symbiote loves Eddie. The symbiote has outright stated it's love for Eddie in the curren Venom run, but Eddie doesn't seem to reciprocat the symbiote's feelings to the same extent. Eddie cares for it, but also doesn't completely trust it.
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 leftover symbiote inside Eddie rejected Venom and transformed him to become a stronger force for good. Now calling himself Anti-Venom, Eddie became a hero dedicated to stopping Venom's influence.
They must “bond with a respiratory host” to survive in an oxygen-rich environment like Earth. We learn this from Jenny Slate's lab-scientist character, the late Dr. Dora Skirth. Symbiotes need to infiltrate the body of an oxygen-breathing creature to thrive in our atmosphere.
The original series climaxes with Spider-Man battling Venom in a burning warehouse, with the combination of the collapsing building and flame being enough to kill Venom.
The end scene shows Eddie and Venom in a hotel room, watching a Mexican soap opera, when they are transported to a different universe. In place of the soap opera on the TV screen is J Jonah Jameson's news report that Peter Parker is Spider-Man, as seen at the end of Spider-Man: Far From Home.
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.
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.
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.
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.

The Anti-Venom symbiote is invulnerable to the traditional weaknesses of symbiotes, fire and sonics. However it particularly vulnerable to a poison Osborn made using the Freak, and its abilities can be negated by Mr. Negative's Darkforce powers.
Spider-Man's shown to be resistant to poison and other harmful chemicals on a number of occasions. This might not be a super crucial skill, but it still serves a purpose. Basically, if a villain ever tries to poison Peter Parker, they're going to be out of luck.
