Much like their "father" Venom, Carnage produced offspring: a third symbiote. Carnage felt only dislike and hatred towards his new spawn, even before he "gave birth" to it, both fearing that it could become much stronger than himself, and being generally disgusted at the thought of giving birth (due to Carnage's host, Cletus Kasady, being male). At the same time, Carnage's rival and "father" Venom became aware that Carnage was "pregnant" and sought out Carnage to talk about this new symbiote. Carnage had resolved to kill his spawn as soon as it was born. Venom was doing his best to protect the new symbiote, with the intention of raising it to become his new partner. Venom was also concerned that, as the 1,000th symbiote of their line, the new symbiote could potentially become psychotic and violent because of genetic breakdown.
After the birth of his "son", Carnage felt too weak to kill his newborn (due in no small part to his attempt to repress the birth after burying himself). Since he could not kill his newborn, he implanted it into Patrick Mulligan and fled, intending to kill him later and destroy the new symbiote when he was up to strength.
Prior to being implanted with the alien symbiote, Patrick Mulligan was one of New York City's finest cops, yet he was also troubled with various personal problems. His stressful job, along with the strain of his new family (his wife, Gina, was pregnant with their first son, Edward) were taking their toll on him. One night, while on duty, he came across the site where Carnage was giving birth to the new symbiote. Carnage, needing a host to hide the symbiote to keep it from Venom, bonded it to Patrick. Carnage resolved to kill both Pat and the symbiote currently hiding in his body since Toxin wasn't yet strong enough to manifest into a super-powered costume like the Venom and Carnage symbiotes. Venom was still hopeful that he'd be able to use this new symbiote as a partner and fought Carnage to a standstill to protect Pat and the symbiote whom he christened Toxin, after himself.
At first, Patrick didn't realize quite what had happened to him, but before long, the Toxin symbiote had matured enough to gain both conscious thought, and the strength to form a symbiote costume on Pat's body. After Carnage attacked Gina and Edward at his home, he realized the symbiote was a danger to both himself and his family. During a future confrontation among Venom, Carnage, and Toxin, Venom realized Patrick was dedicated to a life of virtue, or as close as he could come bearing the symbiote in him. Venom and Carnage formed a temporary pact to destroy Toxin, as it was clear by now that he was easily as strong as either of his predecessors, and was still growing.
Spider-Man stumbled into the final confrontation among the symbiote trio, and helped Toxin. After they fended off Venom and Carnage, Toxin had a conversation with Spider-Man, filling him in on what had happened to him. Spider-Man gave him a kind of superhero heart-to-heart, and Toxin resigned himself to a life of battling his base symbiote urges to indulge in violence and destruction, while trying to harness his power for good. He walked out on his wife and child, and left the police force to try to come to terms with his new life and Symbiote.
powers:
Toxin possesses the special abilities of his two symbiote predecessors: he can stick to walls (which originally came from when Spider-Man was a host of the Venom symbiote)
can change his identity to that of a completely different person,
has unlimited webbing.
Toxin can also blend in with his surroundings and become undetectable, an ability he gained from his grandfather
He can form solid weapons from his limbs, an ability first seen in his father.
Toxin also seems to have some sort of quick-healing ability like his predecessors
Unlike the others, Toxin can track anyone — not just other symbiotes or symbiote hosts — within the entire city of New York and possibly farther, as long as he has something to begin from.
Unlike many of the other symbiotes, Toxin does not try to take over the mind of his human host. Instead, the symbiote actually thinks and voices its opinions to the human host. The symbiote usually speaks when the host is in his "human form", and acts very immature and childlike because of its nascent existence.
In addition, he seems to have a stronger resistance to sonics and intense heat compared to Carnage, though this does not mean that Toxin is more resistant to violent urges: it can get carried away with violence and fighting crime, even if it's a petty crime. When he's not angry or fighting, Toxin is slim and smooth-lined, although still well muscled, closely resembling Carnage or Spider-Man in his symbiote costume. When he becomes upset or aggressive, he grows into his much bigger and stronger form (like Venom), with vicious fangs and long curving claws.
