Garth Reynolds, also known the Zombie-Sentry in his light-form and the Necro-Void in his dark-form, is a clone of Sentry (Robert Reynolds) created by the Dark-Beast (Henry McCoy of Marvel Earth-295). He is a clone of Sentry spliced with the DNA of Zombie (Simon Garth) to make him totally loyal and easily controllable. Zombie-Sentry was a member of Apocalypse's Black Legion, apparently cobbled together in the genetic soup used to created Infinites and other agents of Celestial Evolution. He was led by Blob in confronting what remained of the X-Men.
