Based on the Geoff Johns/Gary Frank 2008 release “Superman: Brainiac,” Superman: Unbound finds the Man of Steel aptly handling day-to-day crime while helping acclimate Supergirl to Earth’s customs and managing Lois Lane’s expectations for their relationship. Personal issues take a back seat when the horrific force responsible for the destruction of Krypton – Brainiac – begins his descent upon Earth. Brainiac has crossed the universe, collecting cities from interesting planets – including Supergirl’s home city of Kandor – and now the all-knowing, ever-improving android has his sights fixed on Metropolis. Superman must summon all of his physical and intellectual resources to protect his city, the love of his life and his newly-arrived cousin.
