One common theme is the struggle for power. The OCs often find themselves in situations where they have to fight for power, either to protect themselves or to gain a position in the ninja world.
One great 'Naruto x Ninja Gaiden' fanfiction is 'The Ninja Alliance'. It combines the unique ninja skills from both universes in an exciting way. The story follows Naruto as he teams up with Ryu Hayabusa to face a new, powerful enemy that threatens both their worlds. The fight scenes are well - written, making it a thrilling read.
The story in 'ninja gaiden black' is an epic tale of a ninja. It begins with our protagonist in a world full of chaos. He is often outnumbered but uses his ninja skills like stealth, agility, and his array of weapons. His story is filled with intense combat sequences against demons and other evil forces. There are also sub - plots related to his relationships with other characters, whether they be allies or enemies. Some of these relationships may be complex, like an old friend who has turned to the dark side, and he has to decide what to do about it.
One idea could be exploring the untold adventures of the next generation in the Naruto world. Maybe focus on how the children of the main characters deal with new threats that are emerging. For example, they could face a new group of rogue ninjas who have a different set of jutsus.
I'm not entirely sure as I haven't read it specifically. But generally, in the Goblin Slayer series, it might be about more adventures of the Goblin Slayer, perhaps exploring new areas, facing different types of goblins or other threats related to the goblin - slaying world.
Well, 'Shadow of the Ninja Gaiden OC' is worth checking out. The OC in this one has a dark past and is on a journey of redemption. It weaves in elements from the original Ninja Gaiden games and creates a new and engaging narrative.
Boruto is an obvious choice. He and Sarada have a unique friendship in the Naruto universe, and their interactions can add a lot of depth to the story. They could go on missions together or have friendly competitions.
Another plot could involve Sarada going on a journey to find out more about her father, Sasuke. She could encounter people who knew Sasuke in his younger days and learn about his past misdeeds and heroic deeds, which would shape her understanding of him and herself as his daughter.
