Prologue:
New York City:
The block lay in ruins. The battle had been fierce and heavily armored cops hauled the insane being known as Carnage was hauled away. Unbeknownst to the cops a small piece of the Carnage symbiote lay on the smashed pavement. It began to rise and crawl towards the helicopter where Carnage was now being secured. But before it could reach it a man stepped out into the street and closed a vial over it. It was trapped.
The man looked into the vial and smiled
The man worked for a company known only as Fisk Industries. Wilson Fisk, the Kingpin of crime had hired these scientists to create another symbiote in order for them to sell on the black market. The scientist took that small sample and pumped it full of mutant growth hormone to nurture it into a powerful independent symbiote.
However they came upon a problem.
With all the mutant growth hormone they pumped into the symbiote, their data showed that it could not sustain itself for much longer without a constant infusion of human DNA. They tried to inject it into themselves, but were immediately rejected by the fledgling symbiote. For this to work, they needed someone younger.
They're guinea pig came in the form of a young black girl, Tonika Cairo. She was on the run and in need of cash. They injected the symbiote into her and it fused with her own DNA to create a child, half human/half symbiote
They called it The Immaculate Conception. As Tonika bore the child the scientists watched with anticipation. Unfortunately, they were discovered. A costumed hero named Daredevil got word of their activities and hunted them down. They only managed to wipe their data before their entire facility was destroyed.
As for the child…
Without Fisk Industries funding her, Tonika could no longer afford to care for him. Her child was born Devon Alexander Cairo. He was completely healthy baby and it broke her heart to give him up for adoption. He went off into to the world unaware of the incredible power, and evil that lay within his body. The last time she saw her child she wished that Devon would have a normal life despite his unusual birth.
Of course it was because of his unusual birth, that a normal life wasn't going to be possible….
