Synopsis for "The Legion of Substitute Heroes!"
After being rejected for membership in the Legion of Super-Heroes, five super-powered teens decide to join together to become the Legion of Substitute Heroes. They are: Night Girl, who has super-human strength but only during the night; Fire-Lad who can breath fire; Chlorophyll Kid who can control plant life; Polar Boy who has freeze powers; and Stone Boy, who can turn into an immobile, and indestructible stone statue at will.
Building a secret base, the Substitute Heroes decide to try and be on call to help the Legion of Super-Heroes when there is trouble. However, whenever there is a mission to be accomplished, the Legion seems adept at solving the problem on their own. However, when the Legion is busy fighting robots in space, the Earth is attacked by a number of Plant Men. Easily defeating them, the Legion of Substitute Heroes tracks the race to their planet, where they find that the Plant Men are preparing for a full scale invasion of the Earth. The Substitute Heroes work together and crush the Plant Men's scheme, using their own reproduction methods against them. Returning to the Earth as unsung heroes in light of the Legion's recent victory over the robots, the Legion of Substitute Heroes decides to remain together, but deciding to keep their victory secret so as not to steal any of the Legion's glory in the hopes that some day they can act publicly as the Legion of Substitute Heroes.
