Twisted

Batman, using retractible wings in his suit, flies over to an abandoned warehouse to confront Harlequin, a deranged murderer who kidnaps people, kills them, and then mutilates their corpses or turns them into toys and taxadermy with freakish grins. He enters and finds sinks filled with blood and a refrigerator with frozen corpses, heads and limbs. Upon entering the basement, he finds several crates, clown themed items and large jack-in-the-boxes, one with a top half of one of Harley's victims. When he finds and frees her latest captive from the third box, Harley enters, enraged at Batman depriving her of a victim, attacks Batman with a large mallet, driving him back, as Harley swings it and swats him through the air when he tries to pounce on her from the ceiling. An intense combat sequence ensues, wherein Harley takes up a chainsaw against Batman, having been disarmed of her mallet, which she strikes against a wall and accidentally destroys along with some of her rotting, human taxidermy while slashing at Batman. Harley, having wounded her abdomen when her chainsaw was destroyed, gives up the fight and permits Batman to take her to prison. However, instead of handing her over to the police, Batman, revealed to have retractable fangs and vampiric hunger, bites her neck and drinks her blood.
