One great 'White OC in HOTD fanfic' might be those that focus on the OC's unique role in the complex politics of the HOTD world. For example, an OC who is a diplomat from a far - off land trying to navigate the power struggles between the different houses. This can add a fresh perspective to the existing storylines.
When writing a 'White OC in HOTD fanfic', it's important to make your OC believable. Don't make them too overpowered right away. Let them grow and develop throughout the story. You can start by giving them some flaws. Maybe they are too trusting or have a fear of certain things. Also, use the setting of HOTD to your advantage. Describe the grand castles, the dragon rides, and the courtly intrigue in detail to draw the readers in.
First, give him a distinct personality trait from his past life that still lingers. For example, if he was a very patient and wise person in his past life, he might still have that calmness about him. Second, let his reincarnation affect his relationships. He might be a bit of an outcast among the half - bloods at first because he's different. Third, give him a goal related to his reincarnation. Maybe he wants to find out why he was reincarnated and who or what is behind it.
When writing a male oc reincarnation fanfiction, you need to think about the rules of reincarnation in your story. Is it a random event? Or is there a greater purpose? Also, make the character's growth believable. If he's suddenly super powerful without any training or struggle, it won't be engaging. Use his past life experiences to influence his actions in the new world. For instance, if he was a scientist, he might approach magic in the new world like a scientific study. And don't forget about the supporting characters. They can help or hinder the male oc's journey.
One popular male oc reincarnation fanfiction could be 'The Reincarnated Prince'. It often features a male original character who is reincarnated into a different world, usually a fantasy realm, and has to navigate through new challenges and powers. Another might be 'Reborn as a Mage', where the male oc is reincarnated with magical abilities and must learn to control them in a world full of magic - using guilds, quests and rivalries as plot devices.
Think about his relationships. In the Naruto world, he'll interact with many characters. He could form a close bond with Naruto, learning from his determination. Or he could have a rivalry with Sasuke, fueling his growth. His relationships should shape his character development.
A frequently seen trope is the 'system upgrade'. As the male oc progresses in the story, his system will also upgrade. This could mean new functions, more powerful abilities, or access to different areas. It gives the character a sense of growth and development. And then there's the 'rival with a system' trope. Sometimes, there will be other characters who also have systems, and the male oc has to compete or cooperate with them. This creates tension and interesting story dynamics.
One idea could be to have the male OC reincarnated as a powerful shinobi from a forgotten clan. He could have unique abilities that set him apart from the regular Naruto characters. For example, he might be able to control a new type of chakra nature that no one has seen before.
Well, 'Blood of the Dragon' is considered a top HotD fanfic. It has amazing character development, especially for the main characters like Rhaenyra and Alicent. Then there's 'The Targaryen Legacy' that follows the descendants of the Targaryens in a new and exciting plotline. 'Fire and Ice: A HotD Tale' is also great. It combines elements of mystery and political intrigue which are very much in line with the themes of HotD.
The plot needs to be engaging. It should blend the elements of the original 'Attack on Titan' series with the new ideas brought by the reincarnation concept. Like, how the OC's presence changes the course of events. Also, the relationships with the existing characters should be believable. Whether it's friendship, rivalry or romance, it has to feel natural within the context of the story. For instance, if the OC becomes friends with Eren, it should be because of some shared goals or mutual respect.
