Theory Time: Earth 23 Token White Guy is…
"Not a "Race Swap" Earth, a Ratio Swap Earth.” - literally everyone.
It does work, the “black versions” of certain heroes as well as other black heroes such as Vixen and Steel make up the Justice League lead by a Last Son of Krypton who happened to be from Vathlo Island. Wonder Woman is explicitly stated to be Nubia (Diana’s “twin” made from “darker clay” from the pre-crisis era when comics could get away with shit like that) and John Stewart is the primary Green Lantern. Although there is a “race swapped” Zatanna the current theory is she is actually Conjura, who is basically to Zatanna what Nubia is to Wonder Woman. Of course Bruce Wayne is still white, still Batman, or is he?
If you haven’t picked up on the social commentary on the comic book industry yet go reread Multiversity #1 until you do (NO DON’T THAT IS WHAT THE GENTRY WANTS, MORE DOORS INTO OUR WORLD. STOP)
It should be noted that the Earth-23 Bruce Wayne is never referred to as Batman on panel, nor is he even referred to as Bruce Wayne, he is just the Justice League’s token white. On the official map of the multiverse entry for Earth 23 Batman is not even mentioned as one of the Earth’s heroes. Diana, Hal and Zatanna have been superseded in popularity by their black counterparts why would Batman be any different. What if David Zavimbe was the first to take up the mantle of the Bat andhad been active as Batman for YEARS in Africa. After a successful career protecting a whole continent by himself he establishes an international corporation to assist other vigilantes. What if Bruce Wayne is just one of dozens of rookie vigilantes across the world offered membership in Batman Inc. What if Bruce Wayne is Batwing, the United States representative of Batman INC.
