The allure lies in the mystery. We get to see how the established Persona lore can be bent with time travel. It's exciting to think about how a character from the present might interact with their past or future self.
Time travel in Persona fanfiction can also be used to explore character development more deeply. A character could be sent forward in time and see the consequences of their actions in the present. This could lead to a transformation in their personality as they strive to change their future selves for the better.
Joker could still be the main protagonist. His ability to adapt and lead the Phantom Thieves would be crucial in a time - travel scenario. He could use his wits and Persona powers to navigate the changes in time and deal with any new enemies or situations that arise.
Maybe the time travel could be caused by a new, mysterious Persona ability. The story could then focus on how the characters deal with the knowledge and power of time manipulation. They might struggle with the moral implications of changing the past.
Perhaps they travel forward in time instead. They could see the consequences of their actions in the future. Maybe they find out that their actions had unintended negative effects on some of their friends or the city as a whole. This would lead them to go back and try to fix things in a different way.
Perhaps the person who initiates the time travel isn't who they seem. It could be an imposter who has their own motives for changing the past, like a Shadow in disguise. This would add a whole new layer of mystery and danger to the story.
The main characters are likely to be the ones from the original Persona 5 game. So, there's Joker, the protagonist. Then there's Ryuji, who is his brash and loyal friend. Morgana, the mysterious cat - like being, also plays a significant role. And of course, Ann, the beautiful and kind - hearted model - in - training.
Perhaps a plotline where the main character has lost some of their memories during the time skip. This would lead to a journey of self - discovery as they try to piece together their past while also facing new threats in the present. They might encounter old friends who have changed and have to re - establish their connections.
Perhaps the fanfiction focuses on the cultural clash between the two groups. The Persona 4 characters are from a small town, while the Persona 5 crew is from the big city. Their different ways of handling things and their unique Personas could lead to some interesting interactions. For example, Yu and Joker might have different leadership styles that they have to reconcile in order to succeed against the shadows.
Some Flash time travel fanfics play with the idea of time travel via dreams. Barry Allen could enter a dream - like state where he experiences different timelines. It's an interesting take as it blurs the line between reality and the subconscious.
