History

After Magento rescued Dazzler from the island of Madripoor, they returned there with Emma Frost and Magik to search for Mystique due to her impersonating Dazzler since she was a S.H.I.E.L.D. agent but with no luck.[1]
Mystique was mentioned in Professor X's will when all the members of the X-Men were present at the mansion. She-Hulk announced two important secrets that Xavier kept from his students, one being that he got married to Mystique before his death, which angered some of the X-Men,since they were thinking that she was going to inherit the school while Emma thought it was the funniest thing she had ever heard.[2]
