A villain like Shigaraki would likely be interested in the power levels in the MCU fanfiction. He's always looking for ways to increase his own power, and seeing the various powerful artifacts and abilities in the MCU might give him some ideas. He could think about how he could use similar things in his own plans to take over the MHA world.
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.
Some MHA characters might be flattered. For example, Midoriya would probably be really excited and take it as a sign of how much he's inspired people. He might even look for positive lessons in the fanfiction to improve himself.
If the MHA characters were to react to a Mastermind fanfiction, some would be more accepting than others. Characters like Ochaco might find it really exciting. She's a fan of the heroes herself, so seeing different takes in fanfiction would be like getting a new perspective on the MHA world. However, characters like Shoto, who are more reserved, might be a bit hesitant. He might need some time to process what he's reading. But overall, it would be a very interesting scenario as it would show how the characters view different interpretations of their world.
Some characters would be shocked. For example, if the fanfiction had a really dark and unexpected Mastermind plot, like a hero turning out to be the mastermind of all the villains' plans, characters like Tsuyu would be very taken aback. She'd probably question the motives behind such a plot. Then there are characters like Denki. He might be more into it if it had some cool action scenes in the fanfiction, regardless of how out - of - the - blue the Mastermind storyline was. And Nejire would probably be super curious about the emotional depth of the characters in the fanfiction.
If it's a Disney fanfiction based on a princess story, the female characters in MHA like Momo Yaoyorozu might relate to the princesses' grace and leadership. Meanwhile, the male characters could either be in awe or a bit dismissive, depending on their personalities. For example, Todoroki might be quietly respectful, while Mineta might make some inappropriate remarks (if we're being honest about his character).
MHA characters might also be a bit jealous of some of the superpowers or unique abilities in other anime fanfiction. In their world, quirks are relatively well - defined, but in some other anime, there are really out - of - this - world powers. They could be in awe of the creativity and at the same time, try to figure out how they could incorporate some of those ideas into their own fighting styles. Like, if they read a fanfiction about a character who can manipulate time, they might start thinking about how they could use their quirks in a time - related way.
In 'Transformers: Rise of the Dark Spark', Grimlock has a series of important involvements. Initially, he is alerted to the threat of the Dark Spark. As the story progresses, he participates in a battle where the Dark Spark's location is being contested. His dinosaur - like abilities, such as his ability to charge and ram into opponents, are put to good use.

In another event, he is part of a group that has to defend a stronghold where the Dark Spark is temporarily hidden. His presence alone is a deterrent to some of the Decepticons, but when he engages in combat, he can cause significant damage to the enemy's forces, which is crucial in the overall struggle for the control of the Dark Spark.

The book " Moving a Magical Beast to a Other World " was a novel about a game, a game, and a different world. The main character, Gawain, transmigrated to a different world of swords and magic, dragons and kobolds, bringing along the " Hearthstone " system. Although it wasn't purely a summoning beast that turned into a Transformers, it also contained the elements of Transformers. I recommend this book to you. I hope you like this fairy's recommendation.😗
