Void (Marvel)

Allegedly due to covering up his past as a thief and addict, Robert Reynolds projects an entity as a dark side effect of his powers. It has been claimed that for every benevolent act the Sentry performs, the Void corresponds with attempting an act of malevolence. He was formerly unaware that the Void was a false personality, but has since been informed otherwise.

Several reasons for the existence of the Void have been given: the innate division between good and evil in any nominally normal person; a "mind virus" put into place by the mutant Mastermind by order of the crazed General; the idea that the Void is in fact the true personality of Rob Reynolds, and the Sentry is the false one; as mentioned above, the result of covering up his past; and, according to Norman Osborn the Sentry's superhumanity eroded his humanity, leading to a 'void' in his life. During the Siege story line, the Void exhibits a more demonic form, capable of nearly slaughtering Thor, bringing down the entire city of Asgard, and striking down every immortal and mortal hero set against it simultaneously, as well later destroying the Norn Stone-powered Loki in seconds. Norman Osborn claims that it is the Angel of Death, undefinedtying into an earlier prelude which showed the Void's presence in biblical times.

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 super strength 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 almost every single bone in his body in moments.
