Phan AU. Five years after the events of 'Hawk and Dove', the mutants have settled into their lives of protecting those who need it and helping their own become heroes. Naturally, things that are good and easy don't last, and the MGGB receive a distress call from their friends in America. While helping the Trifecta deal with a threat that could potentially be the world's first super villain, their ranks are being rapidly shrunk by a sickness that only seems to be infecting mutants.
