One common theme is the clash of cultures. The human has their own set of values and beliefs, which are often very different from the elves'. This leads to misunderstandings and conflicts at first. For example, in many stories, the elves' reverence for nature may be something the human doesn't immediately understand.
Often, a plotline in such fanfiction is the human being captured for a ritual. The dark elves might think the human has some special essence or power that they can use in their dark magic rituals. The human, of course, resists this. Another aspect could be the relationship that develops between the human and a particular dark elf. Maybe they start off as captor and captive but gradually develop a strange friendship or even a romantic relationship, which is a very common trope in this kind of fanfiction.
One popular 'human captured by elves fanfiction' could be 'The Captive Human'. In this story, a human is captured by elves during a journey through a magical forest. The elves initially see the human as a strange and potentially dangerous intruder, but as the story progresses, they begin to understand the human's nature and a complex relationship develops between them.
Typically, the dark elves are shown as powerful. They have advanced magic skills that they use to capture and control the human. They may be seen as cruel, especially in the beginning when they first capture the human. But sometimes, they are also shown as having a complex moral code. So while they might be doing bad things like capturing the human, they might also have reasons like protecting their own kind or following an ancient prophecy.
The theme of magic is quite prevalent. Since they are elves, their magic plays a crucial role in the war. And there is also the theme of redemption. Some elves may seek to redeem themselves for past mistakes during the chaos of the war.
Another theme is the power - up concept. Naruto already has his own set of powerful abilities in his own universe. When combined with the magic of elves in these fanfictions, it creates new and exciting power combinations. It's like seeing Naruto use his chakra in ways that are enhanced by elven magic. And often, this newfound power is used to fight against common enemies that threaten both worlds.
One common theme is the display of Hermione's intelligence. Even when captured, she uses her vast knowledge of magic and her quick thinking to either attempt escape or manipulate her captors. Another theme is friendship. It often shows how her friends, like Harry and Ron, are determined to rescue her, highlighting the strong bonds between them.
One interesting plotline could be the protagonist's struggle to escape from the dark elves' lair while facing various traps and challenges they've set. Another might be the development of an unexpected alliance with a sympathetic dark elf who helps the captive navigate the complex social and political structure within the dark elf community.
Growth and discovery are common themes. The baby elves are often shown learning about their world, like exploring the forests or understanding their elvish heritage.
One common theme is the rescue mission. The friends of Tails will usually band together to save him. For example, Sonic will use his speed to find out where Tails is held and then they will all figure out a plan to break him out.
Common themes in this type of fanfiction include self - discovery. Sasuke may be on a path of self - discovery through his actions of capturing Sakura. He might be trying to figure out who he really is and what he truly wants. Another theme is the exploration of power dynamics. Sasuke is a powerful ninja, and Sakura is also no pushover. When he captures her, the power dynamic between them shifts in an interesting way. This can lead to exploring how they each react to having power or being in a powerless situation. And of course, there is often the theme of forgiveness. Sakura may have to forgive Sasuke for his actions, or Sasuke may have to seek forgiveness from Sakura and others.
