History
Mystique and Freedom Force were ordered to go after Captain America after he refused to relinquish his title. They burst into the Avengers' base, demanding Cap's location. A fight broke that was eventually quelled by Henry Gyrich. When Freedom Force learned that the Avengers didn't know where Cap was, they left.[1]
Notes
- Taking the existence of Destiny into account, it's unknown whether Mystique might've gone by the alias of Sherlock Holmes during the 1880's, like in the main timeline.
