(Note, this story takes place in the few years gap between Venom: Part 2 and The Amazing Spider-Man: Sins Past)
Two years before now, Edward Brock Jr. bonded with a polymer-based, symbiotic life form from the planet Gakaia and tried to kill the man who ruined his life, Peter Parker, despite him being one of the only friends he ever had. They later agreed that Peter would stay out of his life and Brock would stay out of his. However, the influence of the alien instilled an uncontrollable bloodlust, to which Brock was strongly opposed, but if he gets rid of it, he'll die as the suit sucked out vital hormones to survive. After years of deliberation, he decided that the possibility of committing cold-blood murder wasn't worth it, one life lost is fine if it saves countless others. So one day, he went to a rock concert at Central Park, preying on the symbiote's weakness for loud noises. After a few minutes, the suit became more malleable, after a few more, it was loosening its grip, finally, after a few more minutes, Brock could, agonizingly, tear it off, but his screams of pain were attracting some attention from spectators, and by the time he was unconscious, symbiote off, they called an ambulance.
Eddie Brock lay in a bed at the hospital, still unconscious. Peter and Mary Jane were visiting him.
"How is he, doc?" said Peter.
"Not very good." said the doctor, "His adrenaline and phenethylamine levels are dangerously low. We've been doing everything we can to replenish him, we've even been feeding him chocolate in the hopes of replacing the lost phenethylamine, but we didn't expect it to work very well. There's nothing we can do." MJ was crying.
"I think it's best that you leave." said the doctor, "We want Eddie to be as comfortable as possible."
"Okay." said Peter, but before he and his wife left, he whispered, "I'm sorry, Eddie. I'm sorry my actions ruined your life."
That same day, Central Park was visited by a couple men in uniform.
"Who the hell are you?" said the gatekeeper.
"I'm MacDonald Gargan, animal control." said the first man in uniform as he flashed his badge, "This is my partner, Farley Stillwell. We've received reports of a mild scorpion infestation on these premises, may we investigate?"
"Sure." the gatekeeper opened the gate, "I've heard these rumors, never occurred to me to have it checked out." Gargan searched the area, but during his sweep, he felt something stab the back of his leg. He turned and saw a black scorpion with a wide tail had stung him. He recognized the species as very deadly.
"Farley," he said over his radio communicator, "I've been stung. It appears to be a black fat-tailed scorpion."
"That's not good." said Stillwell, "Where are you?"
"I'm under the tall tree in the nearest corner to the entrance. Can you get here with the antivenom in time?"
"'Fraid not. I'm pretty far from there." While Mac was talking to Stillwell, he was being watched by the Venom symbiote. The symbiote recognized that he didn't have long to live. It wanted to ignore him, but was low on sustenance, and something about him made the symbiote feel strange, and before it knew it, the symbiote was starting to bond with him. However, something wasn't right, for it was beginning to take on animalistic characteristics. The new combination wanted to lash out and kill without any reason. It wanted to destroy, it wanted to kill. It didn't care about the consequences, it just wanted to do whatever it wanted. It broke out of the park and began a mad rampage.
