Well, often you'll see the theme of identity. Naruto has to hide or redefine his identity as a hitman, which is different from his known ninja identity. Also, there's the theme of power. How does his ninja - based power compare and interact with the skills required in the hitman business? And then there's the theme of loyalty. Who does he work for and how does that affect his relationships? There are also themes of survival and strategy, as he has to plan his hits carefully just like in his ninja battles.
A common theme is the clash of different assassin cultures. For example, when Hitman crosses with other assassin - themed franchises, their methods of killing, their code of ethics, and their loyalty to their respective organizations are often compared and contrasted.
Yes, there are some interesting ones. You can start by looking on popular fanfiction websites like FanFiction.net or Archive of Our Own. Just search for 'naruto is a hitman crossover' and you'll find a variety of stories. Some might focus on Naruto's skills as a hitman in a different world setting, while others could be more about how his ninja abilities translate into the role of a hitman in a crossover scenario.
Friendship is a very common theme. Since it's about Naruto and his friends in a crossover, it often shows how their bonds are strengthened or tested in the new situations. For example, they might have to rely on each other more than ever.
One common theme is the use of stealth and subterfuge. Characters may need to hide their true identities and motives, much like in both 'Game of Thrones' and 'Hitman'. For example, a character might pretend to be a servant in a great house while actually planning an assassination, similar to how a hitman disguises himself in the game.
A common theme is the clash of cultures. Naruto's ninja culture from his world is very different from the military - and magic - based culture in 'The Gate'. So, exploring how these two cultures interact is often seen. For example, Naruto might introduce the concept of chakra to the people of 'The Gate' world.
Character growth is also a major theme. In a long 'Naruto' crossover fanfiction, Naruto usually has to face new challenges in the crossed - over world. This forces him to adapt and grow in ways he didn't in his original 'Naruto' world. For instance, in a crossover with the 'Fullmetal Alchemist' world, he has to learn about alchemy and its rules, which broadens his understanding and skills.
One common theme is power. The shinju is a powerful entity, and when crossed over with Naruto, it often involves the characters either seeking its power or having to deal with the consequences of its power. For example, in many fics, Naruto might be tempted by the shinju's power to achieve his goals more quickly.
A common theme is the clash and then the fusion of different power systems. Naruto's chakra - based ninja skills and the magic from the other universe, like spells in Harry Potter or magic in Fairy Tail, often start by being at odds but then find a way to work together.
A major theme in these fanfictions is identity struggle. Naruto, being in a chaotic crossover, may question who he is and how he fits into this new, disordered world. Also, the theme of friendship and alliances is quite common. He has to form new alliances with characters from the chaotic world, and these relationships are explored in depth. For instance, he might team up with a chaotic being who has different motives, and they have to work together despite their differences.
One common theme is redemption. Naruto, being banished, often has to prove himself all over again in the new crossovers, seeking redemption for whatever led to his banishment in the first place.
