A plot idea could revolve around a mutant who has the power to manipulate emotions. This mutant could accidentally cause chaos within the New Mutants by making them experience extreme emotions. They then have to figure out how to reverse the effects and learn to control their own emotions better in the process. It could also lead to some interesting character development as they deal with their new - found vulnerabilities.
Perhaps a story where the New Mutants discover a hidden society of mutants that has been living in isolation for centuries. This society has unique powers and a different way of life. The New Mutants have to decide whether to integrate them into their world or leave them be. Along the way, they face challenges from within their own group as some members have different opinions on what should be done.
One idea could be a new mutant with the power to control time joining the group. This would create all sorts of interesting scenarios, like going back in time to prevent a major disaster that was about to befall the mutants. Another could be a crossover where the New Mutants team up with some other superhero group from a different universe to fight a common enemy.
Cannonball is another great character. His power to fly while encased in a protective force field is cool. In fanfiction, you could focus on his leadership potential within the New Mutants. He's often seen as a reliable and strong - willed character, and exploring his relationships with other mutants could be really interesting.
One idea could be that Emma discovers a new power within herself that she can't control at first, and Jess helps her learn to master it. Maybe they have to go on a journey away from the Mutant X team to find a way to keep this power in check. Another plot could be a love triangle between Emma, Jess and another mutant from an opposing group, which creates tension within the Mutant X team.
One idea could be the main character starting a new life in a world full of magic and having to learn to control their newfound powers. For example, they might accidentally set off a magical explosion while trying to cook breakfast on their first day.
A more complex plot might be that there is a dimensional rift that is causing chaos in both universes. Characters from both Fallout New Vegas and RWBY have to work together to close the rift. In the process, they learn about each other's worlds, values, and fighting styles. The contrast between the post - apocalyptic technology and magic - based abilities in RWBY could lead to some really interesting interactions and story developments.
One interesting plot idea could be a crossover where Naruto's world is invaded by a threat from Raven's DC New 52 universe. Naruto and his friends team up with Raven to fight this new enemy. Maybe they have to combine their different powers like Naruto's jutsu and Raven's magic to defeat the powerful foe.
One idea could be that the mutants and the Avengers have to team up against a common enemy that is immune to their individual powers. So they must learn to combine their abilities in new ways. For example, Wolverine's healing factor could be used to keep an injured Avenger alive during a long battle while Iron Man figures out a way to defeat the enemy.
One idea could be exploring the backstories of the minor mutants more. For example, how did they discover their powers before the events of Apocalypse. Another could be a time - travel fanfic where a mutant goes back in time to stop Apocalypse from ever rising to power. Maybe also a fanfic about the mutants trying to adapt to a post - Apocalypse world and rebuilding society in a more mutant - friendly way.
One idea could be exploring a character's backstory that was not fully developed in the original. For example, if there's a side character in 'a new dawn', the fanfiction could delve deep into their past, like their family life or how they came to be in the setting of the story.
Maybe the new girl discovers an old diary in the loft that reveals some hidden secrets about the building's past. She then embarks on a journey with her roommates to uncover the mystery, which brings them closer together. For example, they might find out that there was a famous artist who once lived there and left behind some valuable artworks. The new girl could be the key to solving the clues in the diary.
One idea could be an alternate universe where the Avengers are all villains. They could use their powers for self - gain and cause chaos. Another plot could involve new recruits to the Avengers who have unique and untested powers that the team has to figure out how to use effectively. A third plot idea is that the Avengers have to face a threat that is not from our dimension, like strange creatures from a parallel universe.
