EDIT: Mild spoilers for TDKR under the cut. I’m sorry!!!!
I have minimal source material knowledge here because I am not a DC gal, so– is Bane a POC (or ambiguously probably-not-white) in the comics?
Well, Bane was born on the Caribbean Republic of Santa Prisca (a place made up for the comics but w/e). This I got from Wikipedia. Wrt his parentage, iirc his father is white? With his mother being from the islands. (So we really could/should have had two mixed people in the roles of Talia AND Bane). But I wouldn’t quote me on it— my experience with Bane has been v. limited.
But, yeah, he is definitely unambiguously not white.
