One common plotline could be her sacrificing herself to save the village. Just like Naruto in the original series is always willing to put himself on the line for Konoha, a female Naruto might do the same. She could use her chakra in a powerful and self - destructive way to defeat a great enemy threatening the village.
A third plotline could be related to a disease or curse. She might inherit a deadly illness or be cursed by an enemy. Despite her efforts to fight it, the condition worsens over time until she finally succumbs. This could also be a way to explore the themes of mortality and the transient nature of life in the Naruto universe.
Another plotline might involve her being killed in a political conspiracy within the village. Maybe there are some ninja who oppose her rise to power or her ideas for change in the village. They could plot against her and ultimately lead to her death, which would then cause a great upheaval in Konoha as her friends and allies seek justice.
Often, a plotline involves Batman being captured by a cult - like group. They might have some strange and deadly rituals. Batman, being held captive, is tortured and starved, and his body starts to give out. His only chance of survival is to outwit his captors and escape. This could involve using his knowledge of psychology to manipulate them or finding a weak link in their security. It also might lead to a character arc where Batman re - evaluates his methods and relationships with his enemies and allies after such a close brush with death.
Maybe Naruto is affected by a dark and ancient curse. This curse was placed on him by an unknown enemy. It starts to take hold gradually, making him weak and sick. He begins to have strange visions and nightmares. His body slowly deteriorates, and he loses his appetite. His friends notice his strange behavior and the physical changes, but Naruto is determined to keep fighting until they find out what's wrong with him.
One possible plotline could be that Harry is dying from a mysterious dark curse. His friends, like Hermione and Ron, are desperately searching for a cure. They might travel to far - off places, seeking ancient magic or the help of powerful wizards. Another plotline could be that Harry is sacrificing himself for the greater good, perhaps to defeat a new and powerful dark force. His slow death could be a time of self - reflection and him saying goodbye to his loved ones.
In a fanfiction with Naruto dying from cancer, the story might focus on how the ninja world reacts. His allies from different villages might come together to try and find a cure. However, Naruto, knowing the slim chances, might start to prepare for his death. He could pass on his teachings and the will of fire to the next generation in a more urgent and poignant way. His death could also lead to a shift in the power dynamics among the villages, as he was a unifying figure.
Perhaps in the fanfiction, Tim Drake is poisoned by an unknown enemy. As he is dying, he uses his last moments to pass on important information or clues to his fellow heroes, like Batman and Robin. He could be lying in a hospital bed, his strength fading as he whispers vital secrets.
One possible plotline could be that they are reborn into a different world altogether. Maybe a world where ninjas don't exist, and they have to figure out their new identities and how to get back to each other. They might have some hazy memories of their past lives which gradually come back as they grow older.
One common theme is sacrifice. Female Merlin often sacrifices herself for the greater good, like protecting Camelot or Arthur. It shows her selfless nature. For example, she might take on a powerful enemy alone to save the kingdom.
One common plotline could be Naruto's friends rallying around him. For example, Sasuke might put aside their differences and visit Naruto while he's sick. He could bring some special herbs or medicine that he found during his travels. Another plotline could involve Naruto having a fever and having strange dreams about his past and future. In these dreams, he might see visions of his parents or get premonitions about threats to the village. And sometimes, the story could focus on how the village itself copes with Naruto being sick. The villagers who once shunned him might now realize his importance and come together to support him in his time of need.
Often, in these fanfictions, Naruto is betrayed by Sasuke again in a different way. Sasuke might side with a new group that has a vendetta against Naruto or Konoha. This could lead to some epic battles where Naruto is not only fighting his former friend but also trying to understand why he has been betrayed. It also gives room for Naruto to grow and develop new powers as he faces this new challenge alone.
Another plotline might involve Naruto's friends betraying him. Suppose Sasuke, out of his thirst for power and a twisted sense of rivalry, teams up with some dark forces against Naruto. This would create a lot of emotional turmoil for Naruto as he has always considered Sasuke a brother.
