The Heterodyne Boys and the Dragon from Mars

'The Dragon from Mars is a Heterodyne story made up by Theo to calm the kiddies aboard Castle Wulfenbach. It featured the eponymous "Dragon from Mars" as the Other. Unlike many other Heterodyne stories, Theo gave Klaus a heroic role, allowing him to rescue a wasp-infected Lucrezia Mongfish while the Heterodyne Boys were busy dealing with the dragon itself.

While there probably was no insider information informing the story on Theo's part, the Professors Foglio may have intended it as subtle foreshadowing. There's a lot we don't know yet, so stay tuned.
