In the wake of BVS (also thanks to his interactions with Arthur in the JL trailer), Bruce has discovered an unfortunate fact about himself: he gets off on being beaten up by individuals larger and/or more powerful than he is (specifically metahumans).
(On a personal note, I've been firmly aboard SuperBat for literal years, but all this new material is giving me too many ideas. Especially given that Clark is currently, y'know, dead.)
TL;DR Diana, Arthur, and Victor are very large, very intimidating, and very strong. In the absence of the alien he's becoming obsessed with, Bruce is overwhelmed and can't figure out who he wants to be physically and sexually destroyed by. Whoever it ends up being can be up to the authornon, and all three of them at once is DEFINITELY an option :)
Bruce-centric, meta kink
