Batman #284

February 1977 brings Batman face-to-face with an eerie supernatural threat as the cover — penciled and inked by Jim Aparo — announces the return of the diabolical Dr. Tzin-Tzin. The villain looms large in his dark cape and skull-adorned collar, coolly taunting the Dark Knight while Batman battles a swarm of demonic figures erupting from flames, with two more being conjured even as he fights. It's a vivid, otherworldly challenge that sets a genuinely unsettling tone for David V. Reed's story, brought to life inside by artist Romeo Tanghal and inker Frank Springer.
