She might use her new role to bring justice in a different way. Maybe she'd secretly punish the corrupt nobles who escaped regular justice. The Stranger is often associated with death and the end, so Arya could be the one to end the reigns of tyrants in the fanfic world.
Well, Arya Stark becoming the Stranger in a fanfic could lead to some really interesting character development. Since Arya has always been a bit of an outlier, this new identity would amplify that. She could travel in disguise, using her skills to blend in. And when she reveals herself as the Stranger, it would be a shock to those who knew her before. She might also have new powers or a deeper understanding of the afterlife, which could change the way she views her enemies and friends alike. For example, she could use her newfound knowledge to help the living make better choices so they don't end up on the wrong side of death.
Her relationships would become more complex. Her family might not recognize her at first, and when they do, they might be afraid. Her friends could be both in awe and a bit scared of her new identity.
One possible plot is that Arya comes back to Winterfell with new allies she made during her adventures. These allies could be from different regions or cultures, and they bring with them unique skills and knowledge. Her return might also stir up old rivalries among the people in Winterfell. Some might be jealous of her newfound skills and experiences, while others might see her as a symbol of hope. And as she settles back into Winterfell, she has to navigate the complex web of relationships and power dynamics that have changed in her absence.
Another idea is that Arya uses her skills in a completely new and unexpected way. Instead of relying on her typical stealth and combat skills, she might use her wits to manipulate the situation. For instance, she could spread false rumors among the captors that would cause chaos and confusion, allowing her to slip in and save Ned.
One possible plot could be Arya Stark rebuilding the Stark legacy all by herself. She might use her skills as a Faceless Man to secretly eliminate threats to Winterfell and the North. For example, she could target those who had a part in the downfall of her family during the chaos of the Game of Thrones. With her unique abilities, she would be able to move in the shadows and slowly but surely regain the power and respect that the Stark name once held.
If Arya Stark becomes the Night Queen in a fanfic, it would be quite a shock to the system. Arya has always been a fighter against the forces of darkness, so her becoming the Night Queen would be a complete role reversal. One possible plot could be that she is forced into this position against her will, perhaps by some ancient magic or a deal gone wrong. Then, she has to navigate her new identity while still holding on to some of her old values, which could lead to a lot of internal conflict.
Another idea for a fanfic is that Arya discovers she's not really the last Stark. There could be a long - lost relative hidden away. She then embarks on a journey to find this person. Along the way, she has to overcome many obstacles and face new enemies, all while trying to keep the hope of the Stark family alive.
She could end up ruling over a part of Westeros. Her skills and experiences would make her a great leader.
If Arya becomes the Night Queen, her personality might become more cold and calculating. She has always been a survivor, but as the Night Queen, she would need to be more ruthless to control the White Walkers. Her sense of humor and playfulness might disappear as she takes on this dark and serious role.
One possible plot could be that Arya Stark, through some magical or cross - dimensional event, ends up in the Naruto universe. She could learn chakra control and ninjutsu, while also teaching the Naruto characters her skills of stealth and assassination. For example, she might train Sakura in silent killing techniques, which could add a new dimension to Sakura's combat abilities.
One great Arya Stark dancer fanfic could be 'Arya's Dance of Freedom' which explores Arya's journey through dance in a unique way. It shows her using dance not just as an art form but also as a means of self - expression and survival in a dangerous world.
