One popular theme is the transformation of Naruto into a cold - hearted killer due to some tragic event in his past. For example, the death of his friends like Sasuke could lead him to abandon his kind - hearted nature. Another theme might be his struggle against the ninja world that has wronged him, where he uses his new - found cold - heartedness as a weapon. Also, his relationship with other characters can be explored in a very different light. For instance, how Hinata would react to a Naruto who has lost his warmth and is just a killing machine. This can create a lot of interesting and complex storylines in the fanfiction world.
I don't think so. Naruto is known for his strong sense of justice, his loyalty to his friends, and his will to protect his village. These qualities are completely opposite to what a cold - hearted killer represents. Fanfictions that deviate too much from the original character traits may not be as popular among the mainstream Naruto fanbase.
One potential enemy could be Danzo. In the original series, Danzo had many shady dealings. If Naruto turns cold - hearted, he might see Danzo as a threat to Konoha's true peace and go after him. Another enemy could be Kabuto. After his experiments and all the chaos he caused, a cold - hearted Naruto might not tolerate his existence. Also, there are the Akatsuki members. Naruto could target them in a more ruthless way, especially Pain, who once attacked Konoha and caused a great deal of destruction.
One common theme is the transformation of Naruto's character. His cold - heartedness often stems from some sort of betrayal or past pain, like being ostracized by the village. This changes his once - warm and friendly nature into a cold, more self - centered one.
Another theme could be the exploration of power. Given that Naruto is strong, in a cold and dark fanfiction, his power might be a double - edged sword. It could attract unwanted attention or force him to make difficult choices. Like, he might have to use his power in ways that go against his normal moral code to survive in a harsh, unforgiving world.
Some writers could be exploring the 'what if' scenarios. They might wonder what would happen if Naruto had a different upbringing or faced different traumas that could turn him into a cold - hearted killer. It's a way of delving deeper into the character's potential under extreme circumstances. Also, it could be a form of creative rebellion against the typical positive portrayal of Naruto in the main series.
It could be related to some sort of external influence, like a curse or a dark chakra that has infected him. This could be slowly changing his personality from the warm - hearted Naruto we know to a cold - hearted version. For example, if there was a powerful enemy who placed a curse on him that targeted his emotions.
Well, it depends on the specific fanfiction. Some fanfic authors might write Naruto as cold - hearted for the sake of creating a unique plot or exploring a darker side of the Naruto universe. However, in the main Naruto series, he is far from cold - hearted. He has a big heart and is always trying to save and protect those around him. So, in most cases in fanfiction, it's an interesting but not - so - true - to - the - original take on his character.
One possibility is if he faced extreme betrayal in fanfiction. For example, if his friends turned on him for some reason, it could lead him to become cold - hearted as a form of self - protection. Another factor could be if he lost someone very dear to him in a particularly cruel way and then closed off his emotions.
One common theme could be redemption. The cold - hearted sakura might start off cold but then through various experiences in the story, she begins to change and find a path towards redemption. Another theme could be love conquering all. Despite her cold heart, a love interest might slowly break down her walls.
Well, often there's a theme of mutual respect. Naruto respects Killer Bee's strength and unique fighting style, and vice versa. This respect can develop into a more emotional bond in the fanfiction. Also, the idea of them facing challenges together, not just in battles but also in understanding each other's worlds, is a theme. For example, Naruto trying to understand Killer Bee's love for rap while Killer Bee gets to know more about Naruto's dreams for the ninja world.
