One interesting concept is alternative Servant summonings. For example, seeing a different class for a well - known character like if King Arthur was summoned as a Caster instead of a Saber. Another concept could be different Masters, perhaps a non - traditional or more morally ambiguous Master. And then there are the alternate storylines that might change the location or rules of the Holy Grail War.
One interesting concept could be new Servant classes. Maybe there are unique combinations of skills and abilities that are different from the original classes in the regular Fate series. For example, a Servant with a blend of Assassin and Caster abilities, which would make for very stealthy and magically powerful combat strategies.
One interesting aspect could be the unique character reactions. For example, seeing how different Servants respond to the events of the Holy Grail War in ways that might deviate from the original storyline. It can also be fascinating to see how fanfic writers explore the relationships between characters in new and unexpected ways.
One interesting concept could be the exploration of how the Holy Grail's magic might interact with the existing magic in the Harry Potter universe. For example, it could be a source of power that Voldemort tries to obtain, leading to a whole new series of battles and plot twists.
Another plot idea might be to have a twist where the Grail itself has been corrupted in a different way than in the original story. Maybe it's being influenced by an external dark force, causing the heroic spirits to act more erratically and forcing the masters to question the true purpose of the Grail War.
A great plot idea could be a twist on the class system. What if there was a 'Hidden Class' that was only revealed during this special Holy Grail War? This could lead to all sorts of new strategies and power dynamics. Also, making the Grail itself have a different purpose or a hidden agenda. Instead of just granting wishes, it could be a key to something much larger, like unlocking a lost realm of magic.
Archer is often very popular. His cool and somewhat aloof personality, along with his powerful abilities, make him a favorite. Saber is also a top pick. Her noble image and strong sense of justice are appealing. And Gilgamesh, with his over - the - top arrogance and incredible power, is frequently featured in fanfiction.
One interesting concept could be summoning servants from different time periods and seeing how they interact with the DxD universe. For example, a servant from ancient Greece might have a unique perspective on the devils and angels in DxD. Another concept could be a servant with special powers that are not typically seen in the original series, like a servant who can manipulate time in a different way than what's shown in DxD. Also, the idea of a servant having a secret mission that ties into the overarching plot of DxD could make for an engaging fanfiction.
In the original Fate story, the 'Holy Grail' is a mysterious and coveted item. It's believed to possess the ability to grant any wish, making it the ultimate prize in the battles and conflicts within the narrative.
One idea could be introducing a new type of Servant, like a Servant from a different mythology not previously seen in the Grail Wars. This would bring in new powers and dynamics. Another could be having a master who is an ordinary person thrust into the war by accident and has to quickly learn the ropes. For example, a school student who stumbles upon the Grail War's secrets and has to fight to survive.
A really cool plot for a Naruto Holy Grail War fanfiction could be that the Holy Grail itself has some connection to the Sage of Six Paths. The characters would then be fighting not just for the Grail's power, but also to uncover the secrets it holds about the origin of ninjutsu. The Servants could have unique abilities based on the different elements and kekkei genkai in the Naruto world. For instance, a Servant with the Byakugan could have enhanced perception and long - range attack abilities as part of their Servant skills. The story could also explore how the rules of the Holy Grail War are affected by the different values and beliefs in the Naruto universe.
