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.
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.
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.
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.
In some fanfics, Naruto might be depicted as cold - hearted, but it goes against his canonical character. The original Naruto is known for his warm - heartedness, determination, and his ability to see the good in people. Fanfic authors may take creative liberties for various reasons like exploring different storylines or character arcs, but it's not a common or true - to - the - source representation of Naruto.
One popular 'naruto cold hearted fanfiction' is 'The Ice Within Naruto'. In this story, Naruto has a cold - hearted streak due to some past traumas. He becomes more aloof and calculating, which is a big change from his canon character. It's interesting to see how his relationships with other characters like Sasuke and Sakura are affected.
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.
His cold - heartedness would likely isolate him. In the original Naruto story, his kindness is what draws people to him. But in this fanfiction, if he's cold - hearted, characters like Sakura and Kakashi might be more wary of him. This could cause rifts within the village. The villagers who once saw him as a hero - in - the - making might now fear his cold demeanor, leading to a more divided Konoha.
One possible plot could be that after losing many friends in a major battle, Naruto becomes disillusioned. He might start to see the world as a cruel place where strength is the only thing that matters. So he shuts off his emotions to avoid further pain, and becomes cold - hearted towards his former allies and enemies alike.
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.
