In Supernatural inflation fanfiction, a cool concept could be the inflation of supernatural powers. This could mean that a character's powers grow exponentially, but they have to learn to control it. Like Sam's psychic abilities getting out of control due to some strange inflation factor, and Dean has to find a way to help him without getting killed by the side - effects of those powers.
Another concept could be the inflation of Hogwarts itself. The castle growing larger and larger, with new and strange rooms and corridors appearing. This could lead to new mysteries for the students to solve, like finding a hidden chamber in the newly - inflated part of the castle that holds a powerful magical artifact.
Another concept could be a fanfic that centers around a time - travel plot. Maybe a character goes back in time and tries to change certain events, but not in a way that involves inflation. It could be about preventing a small tragedy that had a big impact on a character's life, and how that changes the course of the 'Naruto' story.
One interesting concept is how the characters' relationships change. For example, if Dean was gender - swapped, his dynamic with Sam might have new emotional undertones. Another concept could be how the genderswapped character approaches hunting. A female Dean might use different tactics or have different insecurities in a male - dominated hunting world.
One interesting concept could be the exploration of the moral gray areas. Monsters being considered as people might lead to stories where their actions, which are typically seen as evil, are re - evaluated. For example, a vampire might be shown to have a complex backstory that justifies its need to feed on blood in a more sympathetic light.
One interesting 'Naruto Belly Inflation Fanfiction' story could be about Naruto accidentally eating a strange fruit that causes his belly to inflate. He then has to find a way to reverse the effect while still going on his ninja adventures.
Since bladder inflation in fanfiction is not a common or appropriate topic for broad sharing, it's advisable to turn our attention to other more acceptable forms of fanfiction. For example, fanfiction that reimagines the endings of classic novels in a more positive light or creates new relationships between beloved characters in a tasteful way.
Well, in such a 'characters meet actors supernatural fanfic', a cool concept is the blurring of the lines between fiction and reality. The characters might be confused as to why these strange humans look exactly like them. And perhaps the actors can use their skills to help the characters solve some supernatural problems. For instance, an actor who has played a wizard - like character might be able to use some of his on - set 'spell - casting' knowledge to assist a real wizard character in the fanfic.
Castiel is also a favorite. His angelic nature and his complex relationship with the Winchesters can take on new dimensions in inflation fanfiction. For instance, if there's an inflation of angelic powers, how he navigates that while still being involved with Sam and Dean makes for great story material.
In the backrooms fanfiction, the concept of the 'safe rooms' is really cool. These are areas within the backrooms where the entities don't seem to go or where the environment is a bit more stable. It gives the characters a brief respite from the constant danger and allows for some interesting plot developments as they plan their next moves.
One interesting concept is exploring different cursed techniques for the characters. For example, in some JJK fanfictions, Yuuji might have a cursed technique that allows him to communicate with the souls of the dead in a more detailed way. Another concept could be alternate universes where the characters have different relationships or roles. In some fanfictions, Megumi could be the main villain instead of an ally, which completely changes the dynamic of the story.
