Amnesiac Batman

Batman's trusty grappling hook didn't hold so well and he endured a pretty nasty fall. He no longer remembers who he is and doesn't remember being Batman or Bruce Wayne. He's disoriented and confused and has no desire to fight crime or be a vigilante. Doesn't remember how to work anything on his batbelt or how to drive the batmobile. Doesn't know where he is or why he's dressed in the bat suit. He just wants to be left alone but people keep alerting his attention to crimes in progress that he wants nothing to do with. Confused, disoriented, grumpy, tired, overwhelmed weary.
