In Naruto fanfiction, a Kaguya OC can play a complex and multi - faceted role. They might start as an antagonist, believing in Kaguya's original ideology of domination. As the story progresses, through interactions with the main characters, they could have a change of heart and become an ally. Their presence can also add depth to the lore of the Naruto universe, as they can reveal more about Kaguya's past and the secrets of the Otsutsuki clan that were previously unknown.
A Kaguya OC can play the role of a catalyst. They can bring new conflicts or solutions to the existing problems in the Naruto world. For instance, if they possess unique powers from the Kaguya lineage, they might be hunted by villains who want to use those powers for evil, which in turn can lead to new adventures for the main characters.
The role of a Kaguya OC could be that of a teacher or guide. They have knowledge about ancient jutsu and the history of the ninja world due to their connection to Kaguya. They can share this knowledge with the younger generation, like Naruto and his friends. Or, they could be a rival to the main characters, constantly challenging them to become stronger, especially if they have a different view on how the ninja world should be run based on their Kaguya heritage.
A Hades OC can play the role of a powerful ally. With their underworld - related powers, they can assist the Avengers in dealing with threats that have a connection to the afterlife or dark magic. For example, if there's a villain raising an army of the dead, the Hades OC can use their power over the dead to stop it.
OC could also be a character from the background of one of the existing Guardians. Maybe they are an old friend from Star - Lord's past on Earth that he thought was lost. Their reunion could stir up old memories and emotions, and also introduce new plot elements such as a hidden treasure or a secret mission that only they know about.
It can play the role of a powerful antagonist. Imagine a dark ninja summoning Cerberus to attack a village. With its three heads and fierce abilities, it would be a formidable foe for the protagonists.
Well, for a Kaguya OC in Naruto fanfiction, start with their appearance. You can make them have some of Kaguya's distinct features but also add your own twists, like different - colored eyes or unique markings. Then, think about their personality. They could be proud of their Kaguya lineage but also conflicted because of the negative connotations associated with Kaguya in the Naruto universe. Their goals are also important. Are they trying to redeem the Kaguya name or are they on a path of destruction like Kaguya once was?
It could be a villain. The male dragon OC might hoard all the gold and treasures in the Lonely Mountain, and the dwarves and Bilbo have to figure out a way to get past it. This is similar to Smaug in the original story but with your own unique take on the dragon's character.
They could be a disruptor. For instance, they might interfere with the Holy Grail War by changing the rules of the game. Just like a hacker in a real - world game, they could make Servants fight against their will or create false quests for the Masters.
They can be a source of inspiration. For instance, their passion for dance might motivate the Turtles to pursue their own hobbies more seriously. Or they could be a sidekick, using their dance skills to help the Turtles in combat, like distracting enemies with flashy moves.
The male OC could also be a rival to Rhaenyra. He may have his own claim to the throne or be part of a group that opposes her rule. This would create a lot of tension and conflict in the fanfiction, making for an exciting read.
They can play the role of a love interest. For example, an OC could be a new vampire who catches the eye of Stefan or Damon. This would add a new dynamic to the love triangles that are so common in the show. Or they could be a mentor figure. An older, more experienced vampire OC could guide the main characters through some of the more difficult situations they face, like dealing with new vampire hunters.
One fanfiction has Kaguya as a sort of mentor to Naruto. After being released from her seal in a different way, she decides to guide Naruto in his journey to master new and powerful forms of chakra. This helps Naruto become even stronger and also gives Kaguya a chance to make amends for her past actions. It's a unique take on their relationship.
