After their leader died in The Ultimate Punishment, most of the members followed her example and committed suicide. The ones who survived became known as the Remnants of Despair and hacked up Junko's body and attached many of her body parts onto themselves.
They did various things for the sake of despair and Junko Enoshima: starved themself, offering up their parents to Enoshima to use for experiments on murder, slaughtering innocent civilians and forcing them to kill themselves as a tribute to their dead leader, and one member who wanted to bear Junko's children so they took an unspecified body part from her. They also started The Tragedy and kept it ongoing even after their leader's death.
Eventually the Future Foundation captured the Remnants of Despair and used New World Program to bring the Remnants of Despair to Jabberwock Island where their memories were reset to before they were manipulated by Junko. The plan was to overwrite the Remnants of Despair's memories with good ones to undo all the damage Junko had done to them, but unfortunently the plan ended in failure due to Junko's interference as a virus AI that was uploaded into the program by the Remnants of Despair, namely, Izuru Kamukura before they were put into the program..
Though the plan ended in failure the ending of the Danganronpa 2: Goodbye Despair implys that even though the plan didn't succed the surviving Remnants of Despair may have kept their memories and were able to recant their status as Ultimate Despair. The surviving Remnants of Despair currently reside on Jabberwock Island and are attempting to find a way to awaken their comatose friends, while the Future Foundation is still cleaning up the world and putting an end to The Tragedy.
