"Isis vs. Cephalopod" from Isis #4 (DC, 1977) by Jack C. Harris, Mike Vosburg and Vince Colletta
DC produced 8 issues of this comic tying in with the live action TV series, the second half of the Shazam/Isis Hour. Like Captain Marvel, she calls on the powers of a gods (well, a single goddess), and there lies the thematic link. After her 15 episodes, she became an animation hero, one of Jason's Super 7 (a major part of my Saturday morning viewing). It's only very recently that DC brought her back, as part of their mainstream universe. She was basically in limbo from 1979 to 2002, but kids my age now writing comics would have remembered her... I'm just surprised she was owned by DC all along.
