After the events of Sonic Generations, the two Eggmen are stranded and trapped in White Space. Metal Sonic takes it upon himself to rescue them, with help from a familiar but not-so-friendly face, as he revisits his old stomping ground.

The Metal Virus has been eradicated and life returns to normal. Shadow approaches Sonic to tell him his plans of ending Eggman for good after the incident. Sonic disagrees with Shadow on principle, but Shadow won't be convinced otherwise. The two find themselves rallying allies for support, creating a post-Metal Virus world civil war. IDWverse, post-Issue #32.
