  • The title of this book is a possible reference to They Call Me Creature and The Howler, two books from the The Nightmare Room series, which were also written by R. L. Stine.
    • Additionally, the concept of a kid unwillingly becoming a superhero is similar to Shadow Girl.
  • Dr. Maniac's appearance in this book was confirmed by Stine's editor Susan Lurie on a Twitter post published on February 14, 2020.[2]
  • This book shares several similarities to the Goosebumps Most Wanted book Dr. Maniac Will See You Now. Dr. Maniac appears in both books, the protagonists of both books are huge comic book fans who create their own superheroes, both books feature a comic book-themed museum and both books feature super villains attacking the town.
