How many potential TV Batmans are there?

Titans Universe
Gotham Universe
Supergirl Universe
Black Lightning Universe
Arrow/Flash Universe

So Five?

Maybe 6 if Batwoman takes place in an Elseworlds universe.

-Adam West Batman
-Birds of Prey (he’s seen in the opening credits, I haven’t seen any episodes with him yet)
-OnStar TV ads from the early '00’s (not a TV show but still TV based)
-Arrowverse (maybe)
-Gotham (eventually)

That’s three for certain, likely four once Gotham ends if we actually see Batman there. Now if you count animated TV, that adds alot more to the count.
