Batman vs. the vampire army. Outnumbered by vicious, super strong and super fast undead, and with only a limited supply of cure for the people of Gotham, he still manages to beat them all. Badass Normal indeed.
In their very first encounter, Dracula literally wipes the floor with Batman, almost nonchalantly so, even. He barely has to do any real fighting, and when he does dodge Batman's garlic-laced batarangs, it's a simple bend or shift to the side, like they're no real threat to him. And when he actually gets his hands dirty, it's freaking brutal. A single shove the chest pushes Bruce back several feet and into a brick wall hard enough to shatter it, slamming him headfirst into the ground cracks the pavement with enough force to leave an impact crater (which, Batman's ability to take that hit is also a moment in and of itself, as that would kill a lesser man), and even then, it's implied that he was holding back! There's just this overwhelming, eerie, chill-inducing sense that he has total control of this entire encounter. His violinLeitmotif even overshadows Batman's guitar leitmotif several times during the fight, if only to undercut the creepy, terrifying tone of the scene as he very nearly bests the Dark Knight and makes him one of his legion of the undead. If it weren't for the sunrise, Batman would have become a vampire as well.
Dracula: You have no concept of the harm of which I am capable.
