- The very world of the humans. Basically, think every continuity from the Godzilla franchise and mix them all together.
- The fact Fluttershy was sucked into a portal while all her friends could do was stand and watch.
- The Kaiju themselves. The fanfiction makes it very clear that the Kaiju (especially Godzilla) are forces of nature that shouldn't be in any way shape or form taken lightly. It's no wonder Empress Scribe deemed that world forbidden, even to her own daughters.
- Twilight stepping through the mirror to the human world. Unlike My Little Pony: Equestria Girls, Twilight is actually given the chance to see her very body stretch like a rubber band as she is sucked screaming into portal.
- Fluttershy's reaction to having been transformed into a human. Unlike Twilight who had a comedic reaction to her humanization in Equestria Girls, Fluttershy's is Played for Drama. Imagine if you woke up after pulled into some sort of light, feeling your body being stretched out like a wad of chewed gum while being warped and contorted like you were made of molding putty and ending up in a world in a new form and unfamiliar surroundings.
- King Ghidorah, Gigan, Monster X, SpaceGodzilla, Hedorah and Destoroyah joining forces.
- Fluttershy has a nightmare where she's blasted by Godzilla.
