That's what I'm calling it if Nolan produces a direct sequel with Robin taking over the role of Batman (and Snyder directing).
What I'd want to see, as soon as this supposed "new Batman" showed up on Gordon's roof; Gordon takes out his gun and starts point blank shooting at him, saying -
"Get off my freakin roof, you piece of **** imposter!"
So yeah , I guess the villain would be whoever this Robin is, supposedly dressing up as Batman.
And yes, I think that's how it should have, and should always play out in the comics too. I think it's a more exceptional approach.
I Know Gordon doesn't know who is behind the mask, but he knows who Batman is, i.e he has a long established and earned trusting relationship with this specific persona.
He'd instantly recognize if it was someone else dressed up.
And he wouldn't automatically just trust somone cause they are in a bat suit. Even if he knew Batman had worked with others, or "side kicks".
On the contrary, he'd be the first to recognize and insist you are NOT Batman, I have no connection with you, Batman is not the freakin suit. And yeah he'd bring the entire force of Gotham's Police Dept. down on this importer - supposed
Batman.
If hypothetically in this "Beyond" scenario Gordon were retired too, or dead, the most ridiculous thing would be if some new Commissioner suddenly by default just decided to trust have an instant relationship with this vigilante dressed as a bat, just cause the previous guy did.
That was a UNIQUE, almost symbiotic relationship, established between those two, specifically. It should
not just transfer to anyone. Not without a drawn out, l personal development of their own.
So again, if they were to make this movie, the most logical first villain would be this supposed "Batman".
As to who they might fight in common, that is pretty irrelevant considering the bigger picture, it could just as well be Mothman if you consider the more interesting villain.
