[DC] Am I supposed to be calling him The Batman or is Batman sufficient? I'd rather not offend him.

As a rule it's "Batman" as a name versus "the Batman" as a description. 

But you can call him whatever you want, he probably won't care. The worst he'd do is tell you to stop calling him something if you manage to accidentally offend him.
