• This episode, alongside "Mr. Crocker, You're Fired", are considered to be the darkest episodes of The All New Fairly OddParents!, until "Lord Chaos Wars", making this the second darkest episode of the fan-made series.
    • Both episodes are similar to Danny Phantom season 2 episode "The Ultimate Enemy", in terms of tone.
  • Timmy's heat vision makes a reappearance from "Father Time!" and "Escape from Unwish Island", as well as his spider powers from "Homewrecker".
  • At the end of the episode, Mr. Crocker has been re-hired as a teacher of Dimmsdale Elementary once again, with Ms. Doombringer quitting the job and swearing revenge on Timmy and his friends when she returns next time.
  • Ms. Doombringer getting armor is similar to Crocker getting armor in the TV movie "Abra-Catastrophe!".
    • In addition, during Cosmo and Astronov's battle with Juandissimo, Astronov turns Cosmo into a magical shield to reflect Juandissimo's attacks.
  • The Giant Bucket of Acid World makes a reappearance from "Crocker Shocker".
  • Unlike in the original series, this is the first time that a character's death happened in the series, with Poof dying.
  • Due to the Big Wand having their wires cut by Juandissimo and their magic no longer working, and Fairy World falling into the Giant Bucket of Acid World, Timmy will have to fight Mrs. Doombringer using his powers that he wished for in the canon series.
  • Similar to what Crocker said to Timmy about Mrs. Doombringer's possible return after "No Subsitute For Crazy", after Ms. Doombringer is defeated and thrown and launched into the catapult back to Earth, Tooth Fairy said to Ms. Doombringer "But not someday soon".
  • Doombringer's fate is left unknown until "Doombringer and Crocker".
  • This is Tootie and Veronica's second visit to Fairy World, the first was in Humanly Fairy World Angels, as they were briefly seen in Poof's funeral.


  • Star Trek II: The Wrath of Khan - Poof sacrificing his life by stopping Fairy World from falling down into the Giant Bucket of Acid World to save the other fairies is a reference to Spock sacrificing himself in Star Trek II: The Wrath of Khan. His funeral is also a reference to that movie.
