In a 'naruto joins obito fanfic', it could start with Naruto being transported to a parallel dimension where Obito has already started his own ninja village. Naruto, seeing the potential in Obito's ideas but also the flaws, decides to join him. He helps Obito to correct his path.

They could then work together to build a village that is a model for the rest of the ninja world, based on both Obito's and Naruto's ideals.
Well, it combines two characters with very different personalities and backgrounds. Obito was initially a kind - hearted boy who turned dark, while Kushina was a strong - willed and fiery woman. Their interaction in fanfics can lead to some really interesting character studies and emotional exploration.

There's also 'The Red and the Black'. In this fanfic, it delves deep into the complex emotions between Obito and Kushina. It starts with a chance encounter that sets off a chain of events that changes their fates. The author does a great job of building tension and drama throughout the story.
One common theme is redemption. Given Obito's past actions, many fanfics explore his journey towards redemption in the context of his relationship with Kakashi. Another theme is friendship turned into something deeper, as they have a long - standing connection that can be developed in various romantic or deeply emotional ways.
Power and sacrifice might be themes as well. Given their roles in the Naruto story, a fanfic could explore how they deal with power, whether it's Obito's Sharingan powers or Sakura's medical and combat skills. Sacrifice could also be a part of the story, like one of them sacrificing something for the other's well - being or for the greater good of their village. This could add an element of drama and depth to the fanfic.
