This one should be great as well! Kurt Busiek’s SUPERMAN: SECRET IDENTITY series from 2004 is not a true ‘Elseworlds’ story, but it does take place outside of the DCU proper. This follow-up mini-series in the same vein focuses on Bruce Wainwright becoming ‘Batman’ in a world without superheroes.
“Young Bruce Wainwright lost his parents in a violent crime…and in the real world, no superheroes exist to save the day. But as grief and rage builds inside Bruce until he feels he can’t keep it inside anymore, something strange starts taking wing in the Gotham night. Perhaps Bruce’s grief isn’t inside him after all? Modern masters Kurt Busiek and John Paul Leon unite for the spiritual companion to the beloved SUPERMAN: SECRET IDENTITY, putting a new spin you’ve never seen before on the legend of Batman-and the dark emotions that drive him.”
