The Void possesses the ability to shape-shift, and through its control over the weather and darkness it can create destructive storms and deadly "infini-tendrils" that attack the mind. Victims impaled on the tendrils experience traumatic visions of the past, present, and future. Its regular appearance varies between a shadowy, trench-coat-wearing villain to a massive hurricane of darkness. It can also assume powers dependent on shape, like a flame form that breathes fire, alternately an armored monster with superstrength and toughness. It is at its strongest during the night and in the Negative Zone, where it has shown itself capable of easily overpowering the Hulk by breaking every single bone in his body in moments. Coincidentally, Sentry is at his weakest in the Negative Zone. A mere physical assault required much effort to hold off, even with the combined force fields of Iron Man, Doctor Strange, and the Invisible Woman, while the united forces of the New Avengers, Fantastic Four, X-Men, Inhumans, Illuminati, and heavily armed S.H.I.E.L.D. agents simultaneously attacked it.
