- There are multiple references to the Hulk, a Marvel superhero:
- The name of the dragon, which may refer to how David/Bruce Banner received his powers after interaction with gamma rays.
- "Kirbixblee" is a combination of the names of the creators of "Hulk", Jack Kirby and Stan Lee, and the actor Bill Bixby who played David Banner on the television show "The Incredible Hulk" (for the television show, Banner's first name was changed to David, rather than the original Bruce).
- "Ferrigneaux" is a likely reference to Lou Ferrigino, who played the "Hulk" in the 1970's television show "The Incredible Hulk".
- "these once tiny and gentle dragons exploded out into the greater world, suddenly huge and green" is likely a reference to the transformation the Hulk goes through.
- "particularly monstrous lightning strike to a banner" is likely reference to the gamma bomb landing on David/Bruce Banner, creating his alter ego, the Hulk.
