10 Characters That Deserve The 'Spider-Verse' Treatment
3. Batman
Grant Morrison introduced the concept of Batman Incorporated some years ago, a team which brought together all of the Batman-esque/inspired heroes from across the globe.
Then, last year Scott Snyder wrote the absolutely bonkers epic of Dark Nights Metal, a story that saw a team of Batmen from the 'Dark Multiverse' join forces under the bat lord Barbatos and invade DC's Prime Earth.
Combine these two concepts and you have a perfect Bat-Verse story: the Prime universe Batman putting together a team of normal multiverse Batmen (as well as members from the Bat-Family) to battle against an army of 'Dark Multiverse' ones. Who wouldn't read that?
Snyder is supposedly working on a sequel to Dark Nights Metal, so perhaps a story such as the one mentioned above could be it?
