Some Transformers could be indifferent. They might see fanfiction as something that has little to do with their real missions and existence. Bumblebee is a popular character, but not all Transformers would care about the stories made up about him in fanfiction. They are more focused on their own tasks and the overall well - being of their kind.
It gives fans a chance to explore different 'what - if' scenarios. By seeing the Avengers' reactions, fans can get a deeper understanding of the characters.
Some fans might be disappointed. Fanfiction often allows them to explore different scenarios with Naruto's character. If he gives it up, it's like closing a door on those creative possibilities.
Harry would probably be cautious at first. He's used to strange things in his world, but these giant mechanical beings would be quite different. Hermione would be curious and start asking a million questions about how they work. Ron might be a bit more fearful, especially if the Transformers made loud noises. But overall, they would likely be intrigued and see if they could be allies against any potential threats.
The Naruto fandom would likely be very divided. Some fans would be extremely outraged as it goes against the core values and character of Naruto. They might condemn such a fanfiction.
On the other hand, there would be fans who would welcome it. Maybe they never liked the pairing in the first place or they think it adds an interesting twist to the story. They could start exploring new relationships for both Sasuke and Sakura in their own fan - created stories.
The Naruto fandom would probably react very negatively. Fans are used to seeing Naruto as a hero, a symbol of hope and growth. A fanfic that portrays him as a slave goes against the very essence of what Naruto represents. There would be a lot of criticism on social media platforms, and many fans might even call for the fanfic to be removed or boycotted.
Well, considering that Titans are mindless creatures in most cases, they may not have a very complex reaction. They would likely see the Transformers as large, moving objects and target them as they would any other large target. But if the Transformers were to use their advanced weaponry and abilities, the Titans might be deterred. For example, if a Transformer used a powerful energy blast, it could make the Titans hesitate or retreat. Also, the Transformers' ability to transform might puzzle the Titans and disrupt their normal behavior patterns.
