His best friends, Ron and Hermione, would probably be the most affected. They're used to seeing him with his old hair, so the change might be a shock at first.
The fandom would be divided. Some fans who are deeply into fanfiction would be disappointed and might feel like a part of their connection to the 'Harry Potter' world has been cut off. However, others who are more focused on the official works might not be as affected. There would likely be a decrease in the variety of fan - created stories, which could limit the creative exploration within the fandom.
It would completely change the nature of the story. Harry Potter is seen as a hero, and this act would make him a villain. It would be a huge deviation from the original story's positive values.
Well, perhaps Harry's new haircut makes him look completely different and his friends don't recognize him at first. It could be a humorous situation where they keep asking who he is until he reveals himself.
The roadside haircut was a new and increasingly popular form of hairdressing. From the perspective of practitioners, most of them were at the bottom of society. The older ones returned to their old jobs, while the younger ones entered the industry for the first time. Although their equipment was simple, it was complete. In summer, they relied on large trees to shade themselves from the sun, and in winter, they relied on the sun to keep warm. This kind of small business had little investment and quick results. It could not only subsidize the family, but also maintain their lives or support their families. In terms of price, roadside haircuts were usually cheaper. For example, there were stalls in Jieyang, Guangdong Province that could get haircuts for 5 yuan, which was in stark contrast to high-end hair salons. This kind of low-cost hairdressing catered to the consumption psychology of low-income people and the people at the bottom of the society. High-end hair salons were expensive. For example, simple hairstyles for the elderly cost 20 - 30 yuan, and young women's hairstyles cost 100 - 500 yuan, which was beyond the affordable capacity of low-income people. Although the environment and equipment for roadside hairdressing were not good, the price was low, friendly, convenient, and the hairstyles for the masses were also accepted, so the business was relatively good. From the perspective of market influence, the emergence of roadside hairdressing reflected the new changes in the supply and demand of the hairdressing market, and also triggered different voices. On the one hand, it met the needs of the people's livelihood, solved the employment problem of practitioners, and also solved the problem of expensive haircuts for low-income people. It also met the needs of some consumers for convenient and low-cost haircuts, and it had its own place with high-end hair salons. On the other hand, some people thought that it had affected the business of traditional barbershops. Some people even called for the regulation of roadside barbers at low prices. However, many netizens supported roadside barbers, believing that their fees were reasonable and more in line with public opinion. In addition, there are also roadside hairdressing practitioners who rely on their own skills or creativity to operate. For example, some hairstylists broadcast live while teaching, while others rely on superb skills to steal most of the business of nearby hairdressing shops. There are also hairstylists like Xiaohua of Huaihua, Hunan Province, who became popular on the Internet because of her superb hairdressing skills. Even if she became popular, the hairdressing price in her shop was 30 yuan for men and 45 yuan for women. Many customers still came from other places to experience her craftsmanship.
The Death Eaters themselves would be affected in an interesting way. Some might welcome Harry with open arms, but others might be suspicious of his sudden change of sides. They might fear that it's a trick by the Order. And within Hogwarts, the students would be in turmoil. Those who idolized Harry would be heartbroken and confused, and there could be a split among the student body depending on who believes Harry's new stance.
His friends would surely be affected. Ron and Hermione might be in awe of his newfound powers. They could also benefit from his abilities. For instance, Harry could use his time - traveling ability to save Hermione from the time - turner accident. And Ron could get some special training from Harry to become a much more powerful wizard himself.
Well, it could change the Hogwarts curriculum in fanfic. Maybe they'd start teaching spells for radiation protection or how to deal with post - nuclear landscapes. And the houses could be re - sorted based on how students react to the threat of nuclear war. Gryffindors might be more likely to volunteer for dangerous missions to help the outside world, while Ravenclaws could be researching magic - based solutions to the nuclear fallout.
The other students at Hogwarts would also be affected. For example, Neville, who looks up to Harry. If Harry ignores everyone, Neville might feel lost. Ginny, who has a special connection with Harry, would be deeply hurt. And the teachers like Snape, who has a complex relationship with Harry, would also be impacted. Snape might be secretly glad at first, but then realize that Harry's isolation could be a sign of a bigger problem in the wizarding world.
His friends would surely be affected. Hermione and Ron might be both amazed and a bit worried. They could be worried that this new power might change Harry too much or put him in more danger. Also, his enemies like Draco Malfoy would be affected. Draco might become more jealous or even more afraid of Harry.
There should not be such fanfiction. 'Harry Potter' is a well - loved and family - friendly franchise. Creating or promoting fanfiction with such improper themes goes against the essence of the series. Most fanfiction communities also have rules against creating offensive or inappropriate works.
