The concept of the story I have in mind is rooted in another, a small story of a vampire hunter, in the story, it's not too important, but it is the chronological beginning of the setting. The gist of the story (Which I drew it up in sophomore year, I have no idea where it is now,) is; the bastard son of a Spanish aristocrat and a peasant woman in 1800's Mexico discovers that vampires are present in the town he lives in when a weak vampire attacks him in his sleep, to his surprise after getting bit, the vampire began burn alive, as his blood is completely caustic to vampires. He takes up vampire hunting, and eventually discovers more oddities in the world, all a result of a strange material that distorts and bends reality when various things are done to it, such as running a current through it. The comic never really got too far into it, as it was just an excuse to have theses weird occurrences in an otherwise normal earth. There was enough present on earth to cause such strange creatures to exist, but come the 1900s, A massive explosion rocks Siberia, bringing in thousands of tonnes of the stuff, this has the effect you'd expect, it wasn't world ending, but things where stranger from that point on. WWII comes around, and the axis powers comes to attain a large quantity of the stuff, they manufacture a weapon of mass destruction with it, and bomb London, The US had just developed its own WMD, the nuke, then they nuke japan, thus ending the war in a stalemate.
Now for the cyberpunk story
I haven't really nailed down the setting, but it has to take place in a mega city with an intense Asian influence, think Hong Kong.
The previous war had left the area the city was in a political gray area, as such it became a haven for just about anyone, gangsters, political fugitives, multinational corporations, and secret societies. Law is loose in this town, and the levels of violence are sky rocketing, the cities council (Made up of businessmen, and various aristocrats) hires multiple paramilitary factions to act as a form of law reinforcement. These Companies are ridiculously competitive, fighting for territory and funds, just like a bunch of glorified gangs. Not to be confused with actual gangs, who control the massive slums of the cities, massive structures of retched squalor and misery. One of these gangs was home to a man named Macready, and he adopted an orphan, a son. His son lived quite comfortably with him and his family, but as a figure head of a large gang, he was a constant target for gangs, and police. One day the cops manage to nab him, and through him in the slammer, one practically run from the inside by a rival gang. The rival gang contacts his son, and hold the life of his adopted father hostage. The ultimatum they give him: Make hits for us, or your father dies. Not wanting to see his father killed, he accepts, now a soldier for men that would like to see him dead, he's forced to run head first in situations so dangerous they'd be the end of the average man.
