One interesting plotline could be about the different factions in Equestria warring over scarce resources. For example, the ponies of Canterlot might be fighting with the ponies from Ponyville due to a shortage of magic crystals. Another could be a story where an unlikely hero emerges from a small group of ponies who were previously overlooked in the war effort. Maybe a group of earth ponies discovers a new way to defend their land against the more magically - inclined opponents.
One interesting plot could be the ponies forming unexpected alliances during the war. For example, ponies from different tribes who usually have differences might come together to fight a common, more powerful enemy. Another plot could involve the discovery of new magical powers or artifacts that change the course of the war. And there could also be plots centered around the moral dilemmas ponies face during war, like whether to sacrifice a few to save many.
The time - travel plotlines are really cool. For example, when they go back in time to fix something that went wrong in the past. It's exciting to see how the characters interact with their past selves and how they try to make things right without changing too much. Then there are the stories about self - discovery. Each character learns more about themselves, their strengths and weaknesses, which is very inspiring.
One interesting plot point could be the culture shock the Equestria Girls experience when they first arrive in Equestria. They might be amazed by the magic that is so commonplace there but strange to them. Another could be their interactions with the ponies. For example, they might have to learn new ways of communication and social norms.
One interesting plotline could be Sasuke and Sakura exploring their new relationship in a post - war world filled with rebuilding. They might face challenges in their relationship due to the traumas of war. Another could be them working together to heal the wounds of the village, both physically and emotionally. Maybe they discover new aspects of each other as they do so.
Well, perhaps in this fanfic, Emiya has to face some moral dilemmas during the fourth war. He might be forced to make choices between saving civilians and achieving his goals in the war. Also, his relationship with his Master could be explored in a new light. What if his Master has a hidden agenda that conflicts with Emiya's own sense of justice? That would surely add a lot of drama to the story.
Another plotline might involve a young pony who has the ability to communicate with the crystals. This pony could then be caught in the middle of the war, with both sides trying to use their unique talent for their own purposes. They might struggle with loyalty and the right path to take.
One interesting plotline could be the resurrection of long - forgotten shinobi who play unexpected roles in the war. For example, some shinobi from the early days of the Hidden Villages might return with unique jutsu that change the tide of battle.
Well, in 'Equestria War Fanfic', Celestia and Luna could be main characters. As the rulers of Equestria, they would have the responsibility of leading their ponies through the war. They might have different strategies on how to handle the situation. Discord could also be a main character, either as a troublemaker who takes advantage of the chaos or as an unexpected ally who uses his chaotic powers to turn the tide of the war.
One interesting plotline could be about the rebuilding of Hogwarts. The war has left it in ruins, and the characters have to come together to restore it to its former glory. They might face challenges like finding the right magical materials and dealing with the memories of the battles that took place there.
Another possible plotline is the strategic battles. The fanfic might detail how different ninja villages coordinated their forces, planned their attacks, and countered the enemy's strategies. It could also explore how alliances were formed and broken during the intense conflict of the Third Shinobi War.
