The Batman vs. Darth Vader.
The way that I envision this is to have Darth Vader pretty much beat the crap out ofThe Batman for the first fight. Bat smoke bombs tossed aside, one of those black containers lifted and thrown at The Batman, maybe missing… then a batarang stopped in midair, then thrown back at The Batman and stabs him in the side (like Jesus!), then another of those black containers and this one hits solidly. Darth Vader uses the Force to pick The Batman up and WHAM! into this wall, WHAM! into that wall. Bring him in close and then a good old fashioned Force Throw over a balcony.
Of course, some helpful group of Rebels catches The Batman and puts him in one of those floating tank thingies for him to heal.
Round two. Darth Vader expresses surprise that The Bat is still alive. He pulls out the red lightsaber. Opens with a the black container throw again… and the container stops in mid-air.
OF COURSE BRUCE WAYNE HAS FORCE POWERS. You knew he would. The Force flows through all living things, man!!! It’s just that Bruce never knew that that is what he had been using since Detective Comics #27!!! And you know what? The Force is strong in this one. The Batman throws the box back at Vader and Vader slices it in half with the lightsaber, and then the two halves go after him. And then the three then the four. The Batman throws a batarang again and pierces the hand holding the lightsaber. The lightsaber falls and The Batman picks it up via the Force and the full-page frame shows Batman holding Vader’s lightsaber.
Yeah, after that I don’t know what really happens because it’s not like you can give Vader to Arkham or hand him over to the Rebels or anything like that.
But that’s how I’d see that fight playing out.
