you know ive decided to drop this, sorry, i just cant think of something interesting
Ideas for everyone
Vigilante Inc - Vigilante Incorporated, a group that promotes home justice and tries to train the common people for their own protection as well as training the more gifted to act as the shadowy guardians of the city
The Family - A religious cult, focusing on blood play and BDSM, they run strip clubs and/or prostitution rings above ground while arranging play dates for the darker citizens.
Hackerz (Anonymous) - A anarchistic group of young people who's skills revolve around computers and cyber warfare. The have arcades and clubs and even a pirate tv show, however unless stirred they mostly stick to the shadows. It is rumoured that they keep track of the more violent denizens of the City.
Suppliers - The underground providers of all that is illegal. They stay out of the crime wars by selling to each group equally. Products consist of drugs, slaves and information.
The Forgotten - A group that organises the homeless and those that suffered from the crime wave the city is suffering. Hiding in sewer systems and underground railways. These people are a force that could be focused in any manner.
Mayor Family - A family that has a long history of politics and the new head of the family is determined to rise once more to the height of mayor of the city. Holdings include lots of things to improve public opinion, like homeless shelters, orphanages, golf clubs etc.
Mastermind Inc - A business organization that focuses on advanced science and robotics, it then uses these powerful objects to try to rule the streets via proxy. It can also unleash items for specific purposes, to create chaos that it can show itself a "hero". It also has a army of lawyers and hackers to take out the competition.
Single Female Lawyer (if you get the joke, good for you

) - A lawyer group profiting from all the violence and crime in the city, it would be up to the owner whether they would be mob lawyers, helping the crime continue, or valiant protectors of the peace trying to put away the bad guys.
Asylum & Prison - With so much crime one could make a business out of running the local prison and mental portion of it. You could also arrange a revolving door service to get people back out, or arrange accidents in prison. The political position as protector of the captured evil could help one run for a political position.
