The Doctor (You can pick which Doctor) lands his TARDIS in Gotham City and finds out that Batman has disappeared after rescuing Catwoman in Arkham City. Armed first with only his sonic screwdriver, his martial arts skills, and his intelligence, the Doctor creates a plan to sneak into Arkham City to investigate Batman`s disappearance and if necessary, defeat Hugo Strange and stop the Joker just as Batman would have done. Will the Doctor survive in Arkham City?
Bonus: Same scenario, only this time the Doctor knew that Batman was going to disappear and has had an entire day of prep. The Doctor has an entire arsenal of gadgets he created during the prep time to carry around in his bigger-on-the-inside pockets. Will the Doctor still survive?
