It is later revealed that Doctor Strange created a device called the Confluctor that created a pocket dimension where Robert Reynolds can go to once every 24 hours to be the Sentry and fight the Void with Scout and Watchdog. This will prevent him from turning into the Void in the real world. Robert confides in Billy Turner (formerly The Scout) about the pocket dimension. Unbeknownst to him, Billy devises a plot with one of Sentry's oldest enemies Cranio to duplicate the Sentry formula and trap Robert Reynolds in the pocket dimension, so Cranio can rule there and Billy will be the new Sentry. The plan is foiled when S.H.I.E.L.D. and Iron Man arrest Robert Reynolds for not checking in on his "parole", but he unleashes the Sentry and escapes. Billy takes the Sentry formula and battles Reynolds. They are evenly matched until Reynolds while in his subconscious thoughts decides to stop fighting the Void and become one with him, creating the newly-merged Sentry. An inexperienced Billy is unable to properly use the full powers of the Sentry and is killed by the Sentry. Then the Sentry removes Cranio from the pocket dimension. Iron Man returns with the Avengers, but they are unable to stop the new Sentry. Realizing they can't stop him, Iron Man asks if he'll do the right thing. Reynolds replies "You don't have a choice" and flies off into space.
