Doctor Mist
Stepping out of the Bronze Age DC Universe with an air of ancient mystery, Doctor Mist made his debut in Super Friends #12 in 1978, conjured into existence by the gifted team of E. Nelson Bridwell and Ramona Fradon. His relatively rare catalog footprint — turning up across Blue Beetle, Justice League International, and DC Comics Presents — only adds to his enigmatic allure, the kind of deep-cut DC figure that serious collectors love to track down. He moves in remarkable company, sharing pages with the likes of Green Lantern, Martian Manhunter, and Bruce Wayne, which speaks to his place in the broader tapestry of DC's rich mythology. With at least one key-issue appearance to his name and a publishing window stretching a full decade, Doctor Mist is exactly the sort of rewarding discovery that reminds you why digging through the Bronze Age back-issue bins is always worth it.
