Cold emotionless characters can change the plot by making different decisions. For example, in a fight, they might not be swayed by emotions like loyalty or fear, so they could choose a more practical but unexpected way to deal with the enemy. This can lead to new alliances or enemies forming.
They often change the social environment in the fanfiction. Since they don't show emotions like others, they can make the other characters around them uncomfortable or curious. This can cause changes in the relationships between characters. For instance, some characters might be drawn to understand them, while others might avoid them. And these relationship changes can then drive the overall plot in new directions. In a Hogwarts setting, they might disrupt the normal house unity or friendship groups.
One could be 'The Icy Heart of Hogwarts'. In this fanfiction, the main character, perhaps a new student, has a cold and emotionless demeanor. They interact with the classic Harry Potter characters in a very detached way, which creates a lot of interesting tension. For example, when facing the challenges in the wizarding world, they solve problems with pure logic rather than relying on emotions like most characters.
One possible fanfic could be about a Harry Potter who has lost all his emotions due to a dark magic spell. He goes through his days at Hogwarts just going through the motions, not feeling joy at Quidditch or friendship with Ron and Hermione. His coldness could lead to misunderstandings among his friends and teachers.
Fanfictions also change character facts by introducing new relationships. For instance, Ginny might be paired with a different character instead of Harry. This changes the whole dynamic of her character's story arc as it was presented in the official books. It also has a ripple effect on the other characters who interact with her in the fan - created story.
I've heard of 'Emotionless in Hogwarts'. It's a fanfic where not only Harry but also some of the other characters start to show signs of coldness and lack of emotion. It could be due to a new type of magic that has seeped into the school. The story focuses on how they deal with this new state of being and how they try to reverse it.
In cold blood Harry Potter fanfics, Harry's personality might become more cynical. Instead of his usual hopeful and somewhat naive self, he could be distrustful of others. For example, he might suspect his friends of having ulterior motives more often.
If Harry has different parents, the plot can change significantly. For example, if his parents are powerful Dark wizards, his upbringing and values would be different. He might not have the same sense of good and evil as in the original. His relationships at Hogwarts would also be different. Instead of being friends with Ron and Hermione who come from 'good' wizarding families, he might be drawn to other students with a darker inclination.
A cold calculating Harry Potter in fanfiction often makes decisions based on pure logic and self - interest. This changes the plot because he may not be as quick to sacrifice himself for others. For instance, when it comes to the Horcruxes. In the original, Harry was quite selfless in his pursuit. But in a 'cold calculating' version, he might weigh the risks more carefully. He could try to find ways to destroy the Horcruxes without putting himself in too much danger. This alteration in his character would then ripple through the entire plot, affecting how other characters interact with him and the overall flow of the story.
If Sherlock Holmes was inserted, he would use his sharp intellect to quickly solve the mysteries in Hogwarts that the students and teachers might be struggling with. This could speed up certain plot points related to uncovering secrets. For example, if there was a mystery about a missing magical artifact, he could piece together the clues much faster than the average wizard.
One example could be a fanfiction where Harry has been through so much trauma that he becomes cold and emotionless. In this type of story, he might isolate himself from his friends at Hogwarts. For instance, he stops joining them for meals in the Great Hall and spends most of his time alone in the Room of Requirement, poring over dark magic books not for evil purposes but to understand the nature of the darkness that has affected him. Another example could be a story set in an alternate universe where Voldemort won, and Harry, as a result, has his spirit broken and becomes cold and unresponsive to the world around him. He might be forced to serve Voldemort in some capacity, but his coldness makes it hard for Voldemort to truly break him completely.
Writers can make Harry cold and emotionless in fanfiction by changing his decision - making process. Instead of making decisions based on his heart and what he believes is right, he now makes cold, calculated decisions. For example, if there's a choice between saving a friend and achieving a strategic goal in the fight against the dark arts, he might choose the latter. His appearance could also be altered to reflect his new state. He might let his hair grow long and unkempt, and his clothes could be dirty and ragged as he no longer cares about his appearance. His interactions with Hogwarts itself could change. He no longer feels the sense of home and belonging, and he might start to break school rules without any remorse.
