Beaming with the power of one million exploding suns, Bob Reynolds was once the shining paragon known as the Sentry. A drug addict who stumbled into an experimental super-soldier formula called the Golden Sentry Serum that gave him inmeasurable powers,[26] Bob used his new-found abilities to become an exemplary and beloved member of the blooming super hero community with his own sidekick named Scout. Reynolds was eventually pushed beyond his limits by the Void, a dark entity that manifested from the hero's fractured psyche; his nemesis and the counterbalance of all the good Bob did as the Sentry. With the help of Mister Fantastic and Doctor Strange, Bob erased the memory of the Sentry's existence from the entire world—even himself—to prevent the Void from resurfacing.[27]
Despite previous attempts to rebury the Sentry when it surfaced as he lived a mundane life,[7] Reynolds eventually came to the attention of the New Avengers. Fully recovering his memories and driving away the Void, the Sentry came back to light once and for all.[28] After the ascension of Norman Osborn as the head of the super hero community, he drafted the Sentry into his own twisted Avengers.[29] Osborn's manipulations caused the Void to return and possess the Sentry in a catastrophic fashion during the Siege of Asgard, resulting in both of their deaths.[30] Through a Life Seed and a Death Seed, Bob would later be returned to life as a Horsemen of Death by the Apocalypse Twins.[22]
With the help of Doctor Strange, Bob set up a pocket dimension inside his own mind called Sentry World, where he could become the Sentry once a day to keep the Void at bay in the real world. A resentful Scout broke into Sentry World in an attempt to steal his old mentor's power, but the Sentry emerged triumphant, in the process absorbing the Void into himself.[31] The Sentry met his end again at the hands of Knull, the God of the Symbiotes, in an ill-fated attempt to stop his invasion of Earth.[23] With the help of Valkyrie, the Sentry's spirit moved on to the afterlife,[32] leaving his powers to manifest in six people back on Earth, one of whom—Mallory Gibbs—became their sole possessor as Solarus.[33]
