They balance each other out.
Do you know any other villain that can pull off clown make-up, a crazy cackling laughter, a morbid sense of humor, and still be the most terrifying guy in the room? They just need to practice their scar story and a couple of magic tricks with pencils and they'll be like mini Heath Ledgers! Our Deluxe Joker Costume ought to do nicely. Batman wouldn't be half the hero he is without the Joker. As villains go, Joker is the best for sure: smart, conniving, surprising, and evil.Which is why we totally approve of your kid wanting to be the Joker.
