Yes, there are likely some out there. Fanfiction websites like FanFiction.net and Archive of Our Own might have such stories. You can search using the relevant tags 'Naruto', 'Bleach', 'godlike', and 'harem' to find them.
One possible plotline could be a dimensional rift that brings the characters of Naruto and Bleach together. Naruto characters end up in the Bleach universe or vice versa. The main character, say a Naruto character in the Bleach world, gradually forms relationships with multiple female characters from both universes, creating a harem. They could go on quests to close the rift while dealing with the different power systems and politics of the two worlds.
Power - up is a common theme. As characters from Naruto and Bleach come together in the harem, they often gain new powers or enhance their existing ones through their interactions. For example, Naruto might learn some spiritual techniques from the Bleach characters.
Another theme is the exploration of different cultures. Since Naruto and Bleach have their own unique cultures, the fanfic often delves into how these cultures interact when the characters are brought together. This can include things like how the ninja way from Naruto might be perceived by the Soul Reapers in Bleach, and how the hierarchies in both worlds are navigated in the context of the harem relationships.
A prevalent theme is the clash of different cultures. Naruto and Bleach have distinct worlds, and in these fanfictions, the mixing of the two cultures from the series leads to interesting scenarios. Also, friendship is often a theme. Despite the harem aspect, the bonds of friendship between characters from both series are explored, sometimes even helping to resolve conflicts in the harem relationships. For example, a character from Naruto might help the main character understand a character from Bleach better in a romantic context.
One common theme is the crossover aspect. Writers like to explore how the different power systems from Naruto (such as chakra and ninja techniques) and Bleach (like reiatsu and zanpakuto abilities) interact when the characters meet. Another theme is friendship. Since it's a harem concept, the friendships that develop between the main character and the multiple characters from both series are often explored. For example, how Naruto might form a bond with Rukia from Bleach and vice versa.
One popular 'naruto x bleach harem fanfiction' is 'The Shinigami - Ninja Alliance'. It has an interesting plot where characters from both Naruto and Bleach universes interact in a unique way. The story focuses on how Naruto characters get involved with the Bleach world's complex power structure and the relationships that develop within the harem.
You can expect a unique crossover. Naruto, being godlike, might have overpowered abilities in the Bleach universe. The harem aspect would likely involve multiple female characters from Bleach having relationships or interactions with Naruto.
Well, it could be about a character who has Naruto - like powers and Bleach - like abilities in a world where he is surrounded by a harem. Maybe he's on a quest to save both the Naruto and Bleach universes and along the way, he attracts various female characters from both series who end up forming his harem.
Well, a common theme in such fanfictions is identity. When characters from Naruto and Bleach come together in a harem setting, they often question or redefine their identities. For instance, a Naruto character might be influenced by the more hierarchical structure of the Bleach world. Another important theme is the struggle for balance. With a harem, there are multiple relationships to manage, and the main character must find a balance between them. Additionally, the theme of cooperation is often present. Given the crossover nature, characters from both series need to cooperate, whether it's in battles or in dealing with the complex harem relationships.
