Rusalka

Emerging from the Copper Age of DC Comics, Rusalka made her debut in Firestorm the Nuclear Man #70 in 1988, courtesy of writer John Ostrander and artist J. J. Birch — a creative team with a sharp eye for compelling new additions to the DC universe. She inhabits a corner of the DC world populated by formidable figures like Stalnoivolk the Steel Wolf, Perun, and Major Zastrow, a cast that gives her appearances a distinctly Cold War-era edge. With only a handful of catalog appearances, she's a rare find — exactly the kind of deep-cut character that rewards the dedicated reader willing to dig into the richer, stranger layers of late-'80s DC storytelling.
