Joker's Body Count

The Joker arguably has the largest single body count of any villain in the DCU. Cheshire, Mongul, Black Adam, and the Secret Society of Super Villains have all devastated entire cities, but the Joker probably has killed the most people in single acts. Part of Joker's high murder rate is because he is largely indiscriminate in how he kills, ranging from the traditional, such as knives, guns, and explosives, to his signature Joker venom and electric buzzer. This list excludes the Emperor Joker storyline, though it's worth mentioning that in that storyline, the Joker not only murdered Batman dozens of times over, but also destroyed first the entire planet, and then nearly the cosmos (luckily, it was all undone).
