Irene Addler, also known as Destiny is Rogue's Foster mother and a close confidante of Mystique's. Destiny seems to truly care for both Mystique and Rogue and usually only shows up when one or both of them are in trouble. The history of the relationship between Mystique and Destiny has yet to be revealed, so how Rogue (Mystique's adopted daughter) came to be in her care is still unknown.
