Kate Kane
Few characters have made a Modern Age entrance quite like Kate Kane — debuting in Countdown #6 in 2008 under the creative eyes of Paul Dini, Keith Giffen, and Mike Norton, she arrived into DC's universe already surrounded by the heaviest hitters in Gotham, sharing pages with Batman, Bruce Wayne, Batgirl, Cassandra Cain, and Robin. Over nearly two decades of publishing history stretching to 2026, she's built an impressive 180-appearance footprint across landmark titles like Detective Comics, DC Comics: Bombshells, and Batman itself, with two of those appearances earning key-issue recognition from collectors. That kind of longevity and that caliber of company speak for themselves — Kate Kane is a character who has genuinely earned her place at the heart of DC's modern mythology, and any serious fan of the Gotham corner of the DCU will want her on their radar.
