(Not DC vs Vampires)
You’d think for a dhampirs called The Batman he’d be a little bit more tolerant with other vampires.
But no, he hunted them down, is hunting you down. He considered himself a vegetarian, no humans no animals either. His human father, the original Batman, taught him not to kill, and to take care of vampires who do so. Instead of killing them he sent them to the only prison in Gotham that could hold vampires. Hell would be a more accurate way to put it.
You were a newer vampire, hungry. You had been going through Gotham killing whoever you could just to fill that hunger. Which is why he’s chasing you down through Gotham. However… when he noticed the sun rising he quickly wrapped his arms around your waist and covers your body with his black cape.
