Trivia · 8 facts

First appearance and origin of the Legion of Substitute Heroes as a team: Polar Boy (Brek Bannin), Night Girl (Lydda Jath), Stone Boy (Dag Wentim), Fire Lad (Staq Mavlen), and Chlorophyll Kid (Ral Benem).
Created by writer Edmond Hamilton and artist/inker John Forte, with lettering by Joe Letterese and editing by Mort Weisinger; cover by Curt Swan and George Klein.
Polar Boy's character concept originated from a reader suggestion published in the Smallville Mailbag column of Adventure Comics #304.
The issue contains two stories: a Superboy/Mxyzptlk backup written by Otto Binder, and the 14-page Legion of Substitute Heroes lead story by Hamilton and Forte.
The cover of the issue mistakenly identifies Polar Boy by the name 'Polar Lad' rather than his correct designation.
The Substitute Heroes' origin story has been reprinted in DC Special Blue Ribbon Digest #1 (1980), Adventure Comics #500 (1983), Legion of Super-Heroes Archives Vol. 2 (1992), Showcase Presents: Legion of Super-Heroes Vol. 1 (2007), and Legion of Super-Heroes: The Silver Age Omnibus Vol. 1 (2017).
The team's origin was later retold in Secrets of the Legion of Super-Heroes #3 (March 1981) and again in Secret Origins vol. 2 #37 (February 1989).
The Legion of Substitute Heroes went on to appear prominently in DC Comics Presents #59 (1983) and the Legion of Substitute Heroes Special #1 (1985), the latter written and drawn by Keith Giffen and regarded as a landmark of Silver Age-era comedy reinvention.
