The crossovers also allow for unique character interactions. Characters from two very different universes get to meet and interact. This can lead to some really interesting dialogues and relationships. For example, Sasuke might interact with Rukia and they could learn from each other's combat styles and philosophies.
There is also 'Bleach - Naruto: The Crossover'. In this fanfiction, the worlds of Naruto and Bleach collide. Characters from both series interact in unexpected ways. For example, Ichigo might meet Naruto and they team up against a common enemy that has something to do with Hollow powers in the Naruto universe.
There's a fanfiction titled 'Naruto: Hollow Evolution' which shows Naruto gradually adapting to his Hollow side while interacting with Bleach characters. It delves deep into how his powers change his personality and relationships. In this story, the author does a great job of blending the two universes' lore.

In a Juubi Naruto Chunin Exams fanfiction, Naruto might struggle with the balance between using the Juubi's power to his advantage and not losing himself. The Chunin Exams are a high - pressure situation already, and with the added factor of the Juubi, it could lead to some intense battles. For example, he could accidentally release too much of the Juubi's power during a fight, endangering his opponents and himself, and then have to figure out how to rein it in.
The idea of Naruto sealing the Juubi is quite common in Naruto fanfictions. If Kurotsuchi is involved, it could be that the author wants to explore a different kind of relationship. For example, Kurotsuchi could be from a different village and her interaction with Naruto during this momentous event could lead to a new alliance or at least a better understanding between their respective villages. Also, the sealing of the Juubi by Naruto is no easy feat. It would require a great deal of chakra control and knowledge of sealing jutsus. Kurotsuchi, with her own skills in earth - based techniques, might be able to contribute in unexpected ways, like creating a stable environment for the sealing to take place.
Rukia would be a great character to include. She has a deep connection with Ichigo and has seen him grow as a Shinigami. Her knowledge of the Soul Society and Hollows could be useful in helping Ichigo deal with his Hollow side. She could also be in conflict with Ichigo's Hollow form if it starts to act in a way she doesn't understand or approve of.
A plot could involve Ichigo being trapped in the Hollow world and having to find a way back. Along the way, he meets other Hollows with different personalities and motives, some of whom he befriends while others are enemies. He discovers secrets about the origin of Hollows and how it relates to his own powers.
Well, you could have an OC Hollow who was once a human with a tragic past. After becoming a Hollow, they retain some of their human memories and emotions. This could lead to some interesting internal conflicts as they struggle between their Hollow instincts and their human side. Also, a story where an OC Hollow teams up with other Hollows to take on a powerful common enemy, like a rogue group of Soul Reapers who are experimenting on Hollows in cruel ways.
