Harley Quinn
Few characters have crashed onto the comics scene with the anarchic energy of Harley Quinn, who made her print debut in The Batman and Robin Adventures #1 in 1995, brought to the page by the legendary Paul Dini and Ty Templeton. Born of the Modern Age and already logging over three decades of DC Comics mayhem, she has proven herself one of the most enduring and electrifying figures the publisher has ever unleashed — racking up an astonishing 352 catalog appearances across titles like Batman, Detective Comics, and DC Comics: Bombshells. She keeps gloriously chaotic company, sharing pages with Batman, Bruce Wayne, Robin, Joker, and Poison Ivy, a rogues' gallery and hero roster that speaks to just how deeply she's woven into Gotham's DNA. With a key issue already to her name and no signs of slowing down through 2026, Harley Quinn isn't just a supporting player — she's become one of DC's most irresistible and irreplaceable stars.
