I think an original character could be a great villain. Maybe a rogue ninja who has mastered a unique and forbidden jutsu that allows him to control the minds of others. He uses this power during the war to turn allies against each other, and Naruto has to figure out how to stop him without harming his friends who are under the villain's control. This villain could have a tragic backstory that led him to this path of destruction.
One idea could be exploring an alternate timeline where the main characters have different allegiances. For example, Sasuke could side with Orochimaru permanently and Naruto has to find a way to bring him back without fighting. Another could be a story where the Akatsuki are actually working for a greater good that was misinterpreted, and Naruto teams up with them to fight a common enemy.
Well, a really cool plot twist might be if the main characters from Naruto are suddenly thrust into the world of Shadow of War. Imagine Naruto and Sasuke having to fight alongside the forces in Shadow of War against an even greater evil. Or perhaps a twist where the tailed beasts in Naruto are somehow connected to the dark magic in Shadow of War, leading to a whole new set of challenges for Naruto and his friends.
In these fanfictions, Naruto might gain new combat abilities inspired by Shadow of War. For example, he could learn to better command his allies in battle like the heroes in Shadow of War do. His shadow clones could also take on new forms or functions similar to the units in the game. Sasuke, on the other hand, might develop a more strategic use of his Sharingan, maybe being able to predict enemy movements in a more detailed way like the orc captains in Shadow of War can anticipate attacks.
In fanfiction, Shelob's role can be complex. She might not just be a simple monster. Some writers might give her a backstory that makes her more sympathetic. For example, she could have been wronged in the past, which led to her current state of being a feared creature. This adds depth to her character and makes the fanfiction more engaging as readers start to see different sides of her.
Shelob is a very interesting character in Shadow of War fanfiction. She is often depicted as a powerful and mysterious being. In many fanfictions, her role might be expanded beyond what we see in the original game, perhaps delving deeper into her motives and her relationship with other characters in the game's universe.
In some fanfictions, Naruto could potentially be depicted as a 'war machine'. Fanfiction often takes creative liberties with characters. Some authors might explore a darker or more militaristic side of Naruto, where his powers are used in a very aggressive, war - like manner. However, this is a departure from his more typical characterizations in the original series.
One common theme is the struggle with power. Talion has the power of the ring, and many fanfictions explore how he grapples with it. Another theme is redemption. Given his actions in the game, some fanfictions focus on whether he can be redeemed.
Another popular orc is Bruz. His betrayal of Talion in the game makes him a great antagonist in fanfiction. Writers can delve deeper into his motives for the betrayal, his relationship with other orcs, and how he continues to be a thorn in Talion's side. He can be portrayed as a power - hungry and conniving orc.
Well, in some fanfictions, Naruto might learn the shadow travel ability through a special training with a hidden shinobi. Maybe this shinobi has a unique jutsu related to shadows and decides to teach Naruto as he sees Naruto's potential.
