Ryker's Island
During the "Shadowland" storyline, Nightshade organized Flashmob, a group of former Luke Cage enemies, in order to take on the new Power Man, Victor Alvarez. Although Flashmob was defeated and incarcerated at Ryker's Island, Nightshade's lawyer Big Ben Donovan mentions that he has plans to have them released from Ryker's Island. Donovan was able to secure the release of some of the members, but others had to remain incarcerated due to the warrants and/or parole violations.
