The idea of being reborn often comes with the plot device of a prophetic dream. You could have dreams that foretell important events in Middle - earth. This could lead you on a journey to prevent disasters or find lost artifacts. Another common plot device is the encounter with ancient spirits or deities. Since you're reborn, they might take an interest in you and offer guidance or tasks. And then there's the plot device of changing the course of history. Your rebirth might be a turning point in the fight against evil in Middle - earth, and you have to make choices that will shape the future of the land.
One common plot device is the transfer of Harry's knowledge from the wizarding world to Middle - earth. For example, she might use her knowledge of potions to create new substances in Middle - earth. Another is her being an outsider who has to prove herself. Just like in the Harry Potter series, fem Harry has to gain the trust of the LOTR characters. And often, there's a plot about her finding a new purpose in Middle - earth, something that ties her to the fate of the Ring.
Power and its corruption is a frequently seen theme. In both universes, power plays a crucial role. In Star Wars, the Force can be misused, and in Lord of the Rings, the One Ring has the power to corrupt. Fanfictions often explore how different characters deal with the allure of power. Also, redemption is a common theme. Characters like Darth Vader in Star Wars or Boromir in Lord of the Rings are often the focus of fanfictions about redemption.
One common plot device is the main character being reborn with prior knowledge. For example, they might know the identities of Batman's villains in advance and use that knowledge to help Batman prevent crimes more effectively. Another is the character having a special ability from their rebirth that aids in the fight against crime in Gotham. Also, a lot of these fanfictions might explore the main character's relationship with Batman and his allies, like Robin or Alfred, in a new and unique way.
Common plot devices in such fanfictions include the protagonist having a special ability or connection with Pokemon. Maybe they can communicate with Pokemon in a unique way, which gives them an edge. There are also often mysterious events or quests that they have to undertake. These could involve ancient Pokemon legends or secrets hidden in the Pokemon world. Regarding the harem part, misunderstandings between the protagonist and the harem members are quite common. For instance, a harem member might misinterpret the protagonist's actions towards another, leading to some comical or tense situations.
One common plot device is the protagonist having unique abilities from their past life. For example, they might have knowledge of advanced fighting techniques that don't exist in the RWBY world yet. Another is the struggle to fit into the new world while still holding onto their old self. They may find it hard to adjust to the different social norms and combat styles. Also, the discovery of new relationships that are influenced by their reincarnated state. They could form unexpected alliances or rivalries because of their different perspective.
A very popular plot device is the existence of parallel universes within the Batfamily context. Writers often explore what would happen if a key event in the Batfamily's history was different in another dimension. For instance, what if Jason Todd never died in one dimension? This allows for a lot of character exploration and interesting interactions between different versions of the characters. Also, the idea of a 'dimensional rift' that the Batfamily has to close before it causes chaos is quite common.
One common plot device is the discovery of a long - lost revival technique. This could be something passed down through generations in a hidden village or an ancient scroll that reveals the secret. Writers often use this to add an element of mystery and adventure to the story.
The plot of Lord of the Rings 1 was that Frodo and his friends experienced many adventures and challenges in the Hobbit journey, including fighting with the Dwarf Golden Boots and going to Middle-earth to find and destroy the Lord of the Rings. During the journey, they made many friends, including Birbo, Gandalf, Legolas, and the dwarf Baggins. In the end, they successfully destroyed the Lord of the Rings, ending the War of the Rings in Middle-earth and protecting the people of Middle-earth.
The use of prophecies is also quite common. Similar to how there are prophecies in both Harry Potter and Game of Thrones, fanfictions might create new prophecies that involve characters from both worlds. For example, a prophecy about a character from Game of Thrones being the key to defeating Voldemort. This creates a sense of destiny and drives the plot forward. Also, the idea of hidden identities can be used, like a character from Harry Potter disguising themselves as a noble in Westeros and causing all sorts of chaos as their true nature and abilities are gradually revealed.
One common plot device is the discovery of a new source of natural energy. In fanfictions, a character might stumble upon a hidden place filled with concentrated natural energy. This discovery then sets off a chain of events, like other characters trying to take over the place or the finder having to protect it.
