Another theme is the clash of cultures. In a 'naruto rage crossover fanfiction', Naruto's ninja - based culture collides with the culture of the other world he crosses into. His rage could be a result of misunderstandings or attempts to protect his own values. For instance, if he crosses into a world where honor is defined very differently, he might get angry when his ninja honor is questioned.
Revenge is also a common theme. If Naruto witnesses something in the crossover world that reminds him of past traumas in his own world, his rage could fuel a desire for revenge. For example, if he sees a character being bullied in a similar way as he was in the Hidden Leaf Village as a child, he might seek revenge on the bully in the crossover world with his ninja skills.
Well, in 'naruto rage fanfiction', a frequent theme is the transformation of Naruto's character. His rage can make him more aggressive and less forgiving. Also, the theme of isolation can be present.

Another theme could be redemption. He has to find a way to control his rage and redeem himself in the eyes of others or in his own eyes.
