"What Do You Mean That's Not Dr. Fate?" from New Adventures of Superboy #25 (DC, 1982) by Martin Pasko, Kurt Schaffenberger and Dave Hunt
My relationship with this title is was predicated on two things, neither of which had anything to do with Superboy. 1) The Gil Kane covers that got me to buy some of the later issues, and 2) the Dial H back-up that kept me buying to the end. The Superboy stories were okay, and I did like some of the antagonists created in the series (Dyna-Mind, Sunburst), and how the the H-Dials crossed into the Superboy universe in #50, but most of them were like the above, featuring Not-Dr. Fate, if you know what I mean.
