Well, it really depends on how the fanfic is written. If the fanfic focuses on Naruto's weaknesses and Danzo's preparedness, Danzo could potentially win. He has a lot of political power and experience. However, if it follows the general power scale of the Naruto universe, Naruto has a better chance. His positive energy and the power of friendship (a bit cheesy but true in Naruto's world) often help him overcome his opponents. Naruto also has the ability to quickly adapt to new situations, which would be a big plus against Danzo.
Sasuke's character would likely become more complex. His act of killing Danzo could push him further into the realm of darkness or, paradoxically, start his journey towards redemption as he realizes the full weight of his actions. Danzo's character, in death, could be revealed in different lights. Maybe his true motives for his actions throughout his life are uncovered, which could affect how other characters view Sasuke's killing of him.
One possible plot twist could be that Danzo is actually being controlled by an even greater enemy. So, when Naruto is about to defeat him, he realizes that there's a bigger threat behind Danzo. Another could be that Danzo reveals a hidden power that he has been suppressing all along and suddenly becomes much stronger than Naruto expected.
One possible plotline could be Sasuke's revenge-driven journey leading up to the moment he kills Danzo. He might discover new secrets about Danzo's past misdeeds that fuel his hatred even more. For example, he could find out about Danzo's role in the Uchiha massacre in greater detail. Another aspect could be the aftermath of the killing. How does it affect the Hidden Leaf Village? Does it lead to chaos or a new understanding of Sasuke's motives among the villagers?
The theme song of Gu Tianle's version of The Condor Heroes was " Mythical Love Words," and the ending song was " Return." The theme song of the TV series " Desire " was " So It's Love ", and the ending song was " Desire ". The theme song of Dragon Ball was "Magic and Unbelievable!" The ending song was " For You, A Romanticism Ronamunte ー ー ". The ending theme song of the TV series " The Beginning " was " My Only." The theme song of " The Palace " was " The Offering of Love." The answers to the other questions were not in the information provided.
The theme song might not be the opening song. Although the theme song usually referred to the opening song, sometimes the theme song could be other songs instead of the opening song. Therefore, the theme song and the opening song could be defined and used differently in a work.
The Song sisters 'theme song was composed by the Japanese composer Kitaro. This theme song was originally composed for the movie " Song Dynasty " and later used in the movie " The Three Song Sisters." The music recounted the changes in the relationship between the three sisters in the turbulent political situation. Kitaro combined Eastern and Western musical instruments in his composition, including symphony, piano, as well as Chinese erhu, pipa, and dulcimbo. This theme song won the 1997 Hong Kong Golden Statue Award and the Taiwan Golden Horse Award for Best Original Music.
I think young Sasuke would have a very intense reaction. He was so consumed by his hatred for Itachi at that young age. A Sasuke vs Itachi fanfiction would be like a trigger for him. He would be eager to see how the fictional fight is portrayed. If Sasuke in the fanfiction is shown as strong, it might fuel his own ego and make him strive even harder to become powerful. However, if the fanfiction shows Itachi as superior, it could enrage him. He might feel that it undermines his own goal of defeating Itachi and he might even want to find the writer to correct their 'wrong' view.
I like Naruto in these fanfics because he always stays true to his beliefs. He is constantly trying to bring Sasuke back to the village and is willing to fight for their friendship.
