Also, without Conroy, rest in peace, it wouldn’t be the same.

While Conroy is my favorite Batman, there have been other good versions and I’d be open to a different one. The real obstacle would be getting Disney and to a lesser extent DC and Warner Bros. on board.

If Batman has time to prep, no contest.

If Xanatos just comes at Batman directly and overtly, sure. But Xanatos isn’t some bankrobber, mob boss or assassin, he’s a mastermind whose schemes are so brilliant that his name is synonymous with plans that end in victory no matter what happens. He’s also a billionaire, industrialist, scientist, martial artist, and even dabbles in magic. He’s essentially a villainous Bruce Wayne, only instead of becoming a ninja he did more of an Iron Man thing. And most importantly, as the villain, Xanatos almost certainly gets to be the one with time to prepare. He gets to be the one who initiates the plot, while Batman has to react and figure out that Xanatos is the bad guy.

Here’s my pitch:

I would assume the plot would involve Xanatos trying to do business with Wayne Enterprises, maybe a joint research project. He sends the pack into Wayne enterprises facility to steal a prototype that he actually has access to already. While their security is compromised Coyote hides a tiny robot disguised as a mundane item (remaining dormant until it’s needed), then ditches the others who all get captured and sent to Arkham. Xanatos then comes to Gotham to assess the damage and evaluate the impact on the project, where he meets with Bruce Wayne.

While those two are wearing their poker faces and sizing each other up, the pack is getting messages from Coyote who has them relaying offers from their employer to inmates like Clayface, Mr Freeze, the Madhatter and Bane (people who have unique abilities or technology, and who want something Xanatos can offer). This will eventually lead to them staging a riot and breaking out, which I think should go wrong when Poison Ivy ensnares, oh, let’s say Jackal with her mind control pheromones.

I would be happy to just have Batman vs Xanatos. but if you want to do a full crossover, you could have Elisa come to Gotham because of the pack and needing to testify because New York is trying to extradite them. The gargoyles come along because they suspect Elisa will be in danger, and because they assume Xanatos is behind it. But they can’t prove anything and Elisa can’t just go around making accusations. This does however allow her to interact with Commissioner Gordon, Bullock etc. which could be fun. She could also interrogate Bruce about the break in, which could also be interesting since she probably assumes the worst about him. You could also have gargoyles fighting escaped Batman villains, could be a lot fun. Really just squeeze in as many fun character interactions as you can.

You could have Batman go after a sighting of a winged creature that he assumes is Man-Bat, only to end up picking a fight with the gargoyles. That could be a pretty awesome fight, though it does rely on a misunderstanding which is not great, and I would rather not have them just tell Batman that Xanatos is the bad guy since he’s a detective and I want him to at least suspect Xanatos on his own.

Eventually you could build up to a climax where Coyote’s remote robot has broken through Wayne Enterprise’s security and is wreaking havoc on their systems. Batman figures out that Xanatos is behind everything, and Xanatos maybe figures out that Bruce Wayne is Batman (or at least that he’s working with him). Cue an epic final battle with Xanatos now upgrading his arsenal with freeze rays, mind control devices and whatever other acquired tech he can bring to the fight. Of course Batman will win, but it will be a hell of a fight.

And if Xanatos has taken Madhatter mind control tech, I have to think he’s going to have a conveniently broken mind control device on under his helmet. That way, even if Batman beats him, he has reasonable doubt on his side. But while Xanatos gets to walk away as a free man, some helpful citizen gives Elisa a stack of internal memos and financial documents that show that there’s a lot of shady bookkeeping going on to pay for those toys Xanatos is using, which should be enough to get the feds to put his whole business under a microscope and make his life a living hell for years. I’d actually love it if Batman hired Clayface away from Xanatos and had him deliver the documents disguised as Owen, conveniently getting caught on camera handing over the files and saying that if anyone asks he’ll deny he gave them anything.
