Power struggle is a common theme. Naruto often has to fight to control the demon power that has taken over him, which creates an internal battle within himself.
One popular 'naruto demon takeover fanfiction' is 'Demon's Embrace'. It has an interesting plot where Naruto gains a unique demon power that changes the course of the story. The characters are well - written and it shows a different side of the Naruto universe.
Well, one interesting idea could be the unique powers that come with the demon takeover. For example, the main character might gain super strength or the ability to control certain elements. Another aspect could be the internal struggle the character faces when the demon influence starts to take over their mind.
Naruto himself could be a main character in such fanfiction. Since he already has the Nine - Tails inside him, it's easy to imagine a story where he has a different kind of demon takeover. Another could be Sasuke. His quest for power might lead him to dabble in some dark magic involving demon takeovers.
One interesting storyline could be Naruto using the takeover magic to assume the powers of different powerful ninja. For example, he might take over the Sharingan abilities from an Uchiha. This would create a whole new dynamic in battles and his relationships with other characters.
It makes Naruto more versatile. Instead of relying solely on his own chakra and ninja techniques, he can now use the powers he takes over. This forces him to adapt quickly to new abilities, which speeds up his character growth.
Yes, there might be. The Naruto fandom is vast and diverse, and fans often come up with creative and unique concepts like Naruto being related to a shark demon. You can try searching on fanfiction websites like FanFiction.net or Archive of Our Own to find such works.
In a Borg takeover in Star Trek fanfiction, one possible plot could be that the Borg target a new and powerful Federation planet. They assimilate key personnel quickly, leading to a race against time for the Enterprise crew to stop the spread. The Borg might use new and unexpected assimilation techniques.
Captain Picard, having been assimilated before, would likely be extremely determined to stop the takeover. He might draw on his past experiences to anticipate the Borg's moves. Kirk, on the other hand, would probably be more impulsive, leading a bold frontal attack against the Borg forces. Spock would use his logical mind to analyze the Borg's patterns and weaknesses.
Power struggle is also very common. The evil clone usually wants to take over the life of the original because it desires the power, status, or relationships that the original has. For instance, if it's a clone of a king, it wants to rule the kingdom. And often there is a battle between the clone and the original or the original's allies to regain control. It's like a fight for who rightfully owns the 'life' in question.
