Kevin McCallister (Home Alone) with prep time (lol perfect) vs Sherlock Holmes and Batman/Bruce Wayne (both unequipped and on the fly). Its not so much a fight as rather who would outsmart the other group. Kevin McCallister is obviously going to have a creative and maniacle defense that both of these intruding detectives, who are unequipped, will have to get past and to Kevin without succumbing to his traps. Batman cannot call in supplies.
