A quick rundown of the NYC organized crime scene:

As has been stated multiple times, the Maggia has been the dominant force for a century. They have multiple families within the Maggia, all of whom fell under the control of Silvermane. With his death, the heads of these families are scrambling for control behind one anothers' backs, while also trying to strategize as a whole how to confront the growing vigilante problem in their city. They have utilized very classic means in their operations throughout the years, and have prior to the start of the RP not entered into the superhuman arms race. 

The Tinkerer is a black market provider of highly advanced technology. He is infamous among the underground and is an incredibly paranoid individual who ensures the location of his organization is never revealed. While he has in the past been seemingly been in the game only for the money, he has begun to make moves indicating his intentions to play a more commanding role in the NYC underbelly. 

The Big Man. An unknown entity and newcomer who has only entered the scene following the death of Silvermane. The Big Man works in the shadows, never revealing their identity. They have spent the last month organizing the various street gangs and small-time criminals under his singular leadership with surprising speed and success.

The Kingpin. I'm not declaring any canon for Fisk, as I'm choosing to leave that entirely in the hands of those who intend to NPC him. However, he's obviously going to be a big player in the coming NYC gang war.
