A common theme is the exploration of the unknown. Since Mephisto is often associated with mystery, fan fictions usually involve the reader character delving into Mephisto's dark and magical world.
One great piece of mephisto x reader fan fiction is 'Mephisto's Encounter' which has an interesting plot where the reader character gets involved in Mephisto's mysterious world. It's full of vivid descriptions and engaging dialogues.
Well, 'Love in the Courtroom' is another great one. It combines the courtroom drama aspect that is so characteristic of the Phoenix Wright series with the budding relationship between Phoenix and Iris. The fanfic is full of suspense, just like in the games, and at the same time, it weaves in the romantic elements very skillfully.
You should also include some foreshadowing. Drop little hints throughout the story before the big betrayal. Maybe Iris has been acting a bit strange lately, or there have been some small disagreements between her and Ash that gradually build up to the ultimate betrayal. This will make the betrayal seem more natural and less out - of - the - blue for the readers.
One possible plot could be that Dragonite gets separated from Iris during a dangerous adventure. Iris is desperate to find it and Dragonite is trying to make its way back to her. Along the way, Dragonite has to face various challenges and meets other Pokémon who either help or hinder its journey back to Iris.
The plot needs to be engaging. It could involve elements from the original games, like courtroom battles, and then add the romantic aspect between them. For example, a case that somehow brings them closer together in an unexpected way. It should also have a good flow, not be too rushed or too slow.
Well, it depends on the writers' imagination and the direction of the story. Sometimes characters take unexpected paths, so Loki ending up there isn't out of the question.
In general, Ash is often depicted as his adventurous and determined self. He might be shown as being a bit naive at times. Iris, on the other hand, is usually portrayed as strong - willed and feisty. However, it's important to note that spank fanfiction is not a typical or widely - accepted form of fanfiction and may contain elements that are not in line with the original characters' personalities in a more official sense.
