[4] During a battling with the gods, he crashed on a desolate planet where All-Black left him and went to Gorr, drawn to his murderous hate, who tried to kill Knull.

The symbiotes subsequently rebelled against their god, imprisoning him at the heart of an artificial planet in the Andromeda Galaxy they called Klyntar, from which they derived the name of their species.

Ashamed of their dark past, the symbiotes desired to spread and maintain peace throughout the Cosmos by seeking out worthy hosts from various species to create an organization of noble warriors.

[6] The corrupted Klyntar became more widespread than their benevolent counterparts, establishing a spacefaring culture dedicated to infecting and overtaking whole planets and reestablishing the Imperium.

These symbiotes forced their hosts to perform death-defying feats to feed off of the resulting surges of hormones, like adrenaline and phenethylamine.

[9] ZZZXX, a symbiote with a predilection for eating brains, was also captured by the Shi'ar, and imprisoned and studied for years until it was released and employed as a Praetorian Guard by Gabriel Summers.

[12] During the Kree-Skrull War, the Kree wanted to replicate the Skrull's shapeshifting abilities; they acquired a newborn symbiote which had been outcast from its species on the planet where Knull had created them.

[17] Spider-Man returned to Earth with the symbiote, where, after discovering that it was an alien lifeform that wanted to bond with him, he managed to separate himself from it by using sound waves to hurt the creature, which took refuge in a church's bell tower.

[18] 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.

[23] When the body of Grendel, the dragon-like composite symbiote defeated by Thor, is discovered on Earth,[24] this reawakens Knull enough to allow him to control the creature.

It is subsequently stopped by the combined efforts of Venom and Miles Morales,[25] and is later incinerated by Eddie, denying Knull the chance to escape Klyntar.

[26] After some months, a cult had gotten hold of Cletus's damaged body inside a chamber and had planned to revive him by using the Grendel's remnants, which they stole from Maker.

In the Ultimate Marvel universe, the Venom suit is a man-made creation born of an experiment by Richard Parker and Edward Brock Sr., who were hoping to develop a protoplasmic cure for severe illnesses.

When bonded with a host and forcibly removed, the suit leaves trace amounts of itself in their bloodstream, which attracts other samples of Venom and allows it to overload Peter's spider-sense.

In the video game Ultimate Spider-Man, absorbing the trace amounts in Peter's blood allowed Eddie to take complete control of the suit, giving him a greater ability to talk and adorning him with a spider symbol on his chest.

[107] The Carnage symbiote also appears in the Ultimate universe as a parasite genetically engineered by Curt Conners and Ben Reilly from Peter's DNA based on Richard's research.

[110] In the Amalgam Comics universe, the Project Cadmus facility which created Spider-Boy started experimenting on a substance that they obtained from an alien spaceship.

[111] In the alternate universe of the Marvel Comics 2, or MC2 imprint, Norman Osborn obtained Eddie's blood (he was still bonded to Venom at the time) and extracted the symbiote codex.

The government, in an attempt to stop her, used pieces of the dead Carnage symbiote (after it had been killed by Mayday) to create living weapons dubbed Bio-Predators.

Mayhem, seeing the error of her ways, went back in time and sacrificed herself to stop her past self from killing Spider-Girl, ensuring the events that led to the Biopreds' creation never occurred, even though she may have survived.

[114] During the 2018 "Spider-Geddon" storyline, in the universe of Peni Parker, aka SP//dr, VEN#m is a giant mech-suit, powered by a Sym Engine and created to serve as back-up in case the SP//dr failed.

Some time afterward, the Venom symbiote leaves its current host Mac Gargan and merges with Peter, who was inside a cocoon to become Poison.

The last images reveals Poison watching over a new cocoon like his own, as it bursts forth showing a hand similar to Carnage's, even though the normal symbiotes are unable to bond with dead hosts.

[117] In Spider-Man: India, the symbiotes are parasitic demons with outward tusk-like fangs, who had ruled the world in the past but got trapped inside an amulet.

In the 2016 Contest of Champions series, where Maestro and Collector use the heroes of different worlds to battle with each other, when this version of Venom was killed by Punisher 2099, the remnants fused with the remains of the Void, creating the Symbioids.

[120] In the universe of Earth-9997 / Earth X, the symbiotes, like all sentient life, were created by the Celestials as "antibodies" to protect the embryos which resided in the core of the planets.

Like the Asgardians and Mephisto, the symbiotes eventually reached the third stage of metamorphosis and apotheosized into metaphysical entities, given physical form by what others believed them to be and required of them.

Unfortunately, the symbiote is able to escape captivity and bond with Reed Richards, allowing its subsequent spawn to be altered so that they are immune to most of its traditional weaknesses.

[125] In the Marvel Adventures continuity, primarily aimed at younger readers, this universe's Spider-Man comes into contact with the Black Suit at the Tinkerer's junkyard.

While trying to take down the combined efforts of Stilt-Man, Rocket Racer, and Leap Frog, Spider-Man comes into contact with a "stealth fabric", a liquid alloy that can quickly adapt to the user's body.
