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 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.
Antagonists can also be really interesting to focus on. In 'a new dawn', they might have their own reasons for being the 'bad guy' that were not fully explored in the original. A fanfiction could humanize them more, show their internal struggles.
Hermione Granger is always a popular choice. You can explore her further adventures in the wizarding world, like her research into new spells or her efforts to improve the lives of house - elves. Another is Draco Malfoy. There's a lot of potential to show his redemption arc in more depth or his post - Hogwarts life trying to make amends for his past actions. And of course, Harry Potter himself. You could write about his life as an adult, perhaps as a teacher at Hogwarts or his continued battles against the remnants of dark magic.
The X-Men New Mutant comics often have unique characters with diverse powers and complex storylines. They explore themes of adolescence, identity, and belonging within the mutant world.
Beast himself is a great character to focus on. His intelligence and his struggle with his bestial form can lead to a lot of interesting storylines. For example, a story could explore his scientific research to find a cure for his mutation while also dealing with the moral implications of changing who he is.
Basara Toujou is a very popular character to focus on. He's the main protagonist, so there are a lot of aspects of his character that can be explored further. His relationship with the sisters, his growth in power, and his moral dilemmas are all great areas for fanfiction. Mio Naruse is also popular. As one of the sisters, her backstory as a demon and her feelings for Basara offer rich material for fan - created stories. And then there's Maria Naruse, with her mysterious powers and her somewhat teasing relationship with Basara, she can be a really fun character to write about in fanfiction.
One potential crossover character could be Harry Potter himself as a mutant. Maybe he has an additional power like telepathy on top of his wizarding abilities. Another could be Professor Xavier in the wizarding world, using his mental powers to communicate with wizards. Wolverine could also be a great crossover, his adamantium claws and healing factor in the context of the wizarding world would be really interesting.
The new girl herself is an obvious choice. Her fresh perspective and unique personality can drive the story. You can explore her journey of adapting to the new living situation and her relationships with the roommates.
In a 'new x men story', the main characters would most likely include some of the classic X - Men such as Jean Grey. Her powerful psychic abilities would be crucial in many situations. Also, Beast with his super - intelligence and physical abilities. And of course, Rogue, who has her unique power - absorbing ability. There could also be new mutants introduced as main characters, who bring their own fresh perspectives and powers to the story.
Wolverine is always a great choice. His tough - guy attitude and healing factor make him adaptable in any crossover situation. He could hold his own against powerful characters from other universes. Another good one is Storm. Her control over the weather can be a game - changer in battles. In a crossover, she could use her powers to combat foes that others might struggle with.
