Well, there could be a fanfiction storyline where the time - traveling DeLorean gets stuck in a time loop. Marty has to figure out how to break the loop while also dealing with the changes in the timelines that are occurring because of it. It could involve him meeting different versions of his friends and family at different points in the loop, and trying to piece together what's going on.
In some Back to the Future The Game fanfiction, there might be a storyline where an enemy from the future tries to steal the secrets of time travel from Doc Brown. This enemy could be a rogue scientist who wants to use time travel for his own evil purposes. Marty and Doc then have to team up to stop this person, traveling to different eras to outwit the enemy and protect the integrity of the time - space continuum.
One interesting storyline could be the resurrection of some beloved characters in a different way than in the original series. For example, Ned Stark coming back with new knowledge and a plan to change the future of Westeros. Another could be the rise of a new, unexpected alliance between former enemies, like the Lannisters and the Starks, united by a greater threat from across the Narrow Sea. And perhaps a storyline where Daenerys, instead of going mad, finds a way to rule justly with the help of new advisors from the future who know the mistakes she could make.
Some fanfictions focus on the backstories of minor characters. For example, a story about the life of a Night's Watch member before he joined. It could explore his reasons for joining, his family, and how he coped with the harsh life at the Wall. There are also fanfictions that rewrite the end of the series in a more satisfactory way for fans, like Jon Snow actually ruling the Seven Kingdoms in a more just and prosperous manner.
Perhaps a story where characters from different backgrounds form an unlikely alliance. They have to overcome their differences and prejudices in order to face a common enemy that threatens the entire world of the fanfiction.
Another storyline could focus on the relationships between the different factions within the tyranny game world. For example, how two opposing factions might be forced to cooperate against an even greater threat that the tyrant has unleashed. This could involve a lot of political intrigue and character development as they learn to trust each other.
One interesting storyline could be a character from a lower - ranked team rising to become a champion through sheer determination and hard work. They might face numerous challenges and rivalries along the way.
One interesting storyline could be a character from a lower class rising to great power through unexpected means. For example, a peasant who discovers a long - lost magic that changes the balance of power in the fictional world.
One interesting storyline could be Rayne's encounter with a new and powerful vampire clan that has a different set of abilities and weaknesses compared to those she has faced before. This could lead to intense battles and her having to adapt her fighting style.
One interesting storyline could be about the main character from 'Overlord' facing unexpected challenges in the game world that are not part of the original game mechanics. For example, they might have to deal with a glitch that creates new and dangerous enemies.
One idea could be a crossover with 'Doctor Who'. The TARDIS could land in Hill Valley, and the Doctor could team up with Marty McFly. They could use the time - traveling capabilities of both the DeLorean and the TARDIS to fix some major time - related disasters across different universes.
