The Hulk, if he was in his Bruce Banner form, would be very worried. He'd use his scientific knowledge to figure out a way to counter Thanos' power. But if he was in his Hulk form, he'd just be enraged and want to smash his way to Black Widow. The other Avengers like Thor would also be determined to rescue her. Thor, with his newfound strength and his axe Stormbreaker, would be ready to face Thanos head - on to free Black Widow.
The Avengers would likely have mixed reactions. Captain America might be very protective, seeing it as his duty to safeguard Black Widow and her unborn child. Tony Stark, on the other hand, might initially be more concerned about how this would affect their battle strategies.
She might be initially scared but quickly regain her composure. Uraraka is a brave character. She would likely start looking for ways to escape, using her zero - gravity quirk to her advantage, like floating up to vents or disabling the villains' weapons if she can.
Midoriya's family would be ecstatic. His mother would be busy helping with the wedding preparations, giving advice on everything from the dress to the food. Uraraka's family would be equally happy. They would see Midoriya as a kind - hearted and strong young man. Her mother would likely bond with Midoriya's mother over the wedding plans, and the two families would come together to celebrate the union of the two young heroes.
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.
Natasha Romanoff, the Black Widow, hails from a dark past. She was orphaned during World War II and then taken in by the Soviets. In the Red Room, she endured rigorous training, both physical and mental. This training made her an expert in combat, espionage, and deception. Her skills are on par with some of the mightiest superheroes in the Marvel Cinematic Universe. For example, she can hold her own against the likes of Hawkeye and even Captain America in combat situations. Her origin story is a crucial part of understanding her character's motives and actions throughout the Marvel stories.
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.
" Rebirth Through Time: Black Woman Invincible " and " Widow's Blessing " were two novels that described women who transmigrated to become black widows. Both novels described the heroine's efforts to prove her worth in the new world and finally succeed.
