Powers: Seismic powers, able to create earthquakes on a large scale.
Bio: Although she is often thought to be a mutant with seismic (earthquake-producing) ability, her powers come from her status as the illegitimate daughter of Calvin Zabo, the supervillain known as Mister Hyde (like certain other progeny of Marvel mutants, her genetics changed post-conception). Taken in by S.H.I.E.L.D. she is under the direct supervision of its longtime executive director, Nick Fury, even after the latter's defection from the agency during the events of the "Secret War" intracompany crossover event. She possesses a "Level 10" security clearance, the only known agent aside from Fury and the Black Widow (Natasha Romanova) to do so.
In her most visible action, Johnson has helped to defeat the powerful mutant rebel leader Magneto by inducing a vibration in his brain that made him lose consciousness. She states in this appearance that if the superhero team the Avengers let her join, she would adopt the moniker "Quake".
Notes: Received her official codename in Secret Invasion #4.
