I'm pretty sure Cassie takes this. Bane woud be a handful but cassie just outskills him and would eventually take him out. Key word "eventually", Bane would be a threat but cassie looks at him at immediately knows how to take him out
Eh, Dick doesn’t want to be Batman and Damian... I’d imagine something like Batman 666 would happen. And I believe it was shown that she cares about the Batman ideal more than anything, so I consider her his true successor. Anyways, vote counted.
I don’t know if Bane could tank everything she had, keep in mind that a hindered Cass could one-shot Lady Shiva, who could take down Killer Croc with one arm and is consistently shown as Batman’s superior.
