In case you didn’t know, back-up stories were quite common throughout the Silver and Bronze Ages. Back-ups were often used to introduce new characters/concepts that might not otherwise support their own books, thus providing readers with more bang for the buck. However, back-ups fell out of favor as the miniseries/maxiseries format became more common and popular with readers (circa mid-1980s).
During the 1980s, in particular, several of DC’s fan-favorite characters received notable back-up series:
- Firestorm: multi-issue back-up in The Flash; Firestorm then graduated to his own series once again (Fury of Firestorm).
- Dr. Fate: multi-issue back-up back-up in The Flash; these stories were reprinted in the Immortal Dr. Fate miniseries.
- Huntress (Helena Wayne): long running back-up in Wonder Women; Huntress was supposed to receive her own miniseries, but she was killed-off in Crisis On Infinite Earths.
- Arion: multi-issue back-up in The Warlord; Arion then graduated to his own series.
