In some fanfictions, a plot twist might be that the kidnapping was a ruse all along. Dabi and Shouto could be in on it together to expose a conspiracy within their hero/villain society. Shouto could be using this 'kidnapping' as a way to go undercover and gather information that can't be obtained any other way.
One common plot twist could be that Dabi has a hidden motive other than just kidnapping Shouto. Maybe he's being controlled by a greater villain. Another could be that Shouto has some hidden power that he discovers during the kidnapping ordeal. For example, he might find a new way to control his fire and ice powers to escape.
A plot twist could be that Dabi actually has a change of heart. He kidnaps Shouto initially with malicious intent, but as time passes, he realizes that Shouto is not what he thought. Maybe he starts to see Shouto as a victim of the same system he hates. This could lead to an unexpected alliance between them against a common enemy.
There are also cases where Shouto could be in shock. The suddenness of the kidnapping could leave him stunned for a while. During this time, Dabi could have the upper hand. But as Shouto recovers, his natural instincts as a hero trainee kick in, and he starts to think of ways to get free and stop Dabi's plan, whatever it may be.
The theme of acceptance is also quite prevalent. Shouto might be forced to accept Dabi for who he is, despite his villainous actions. And there's also the theme of power dynamics. Their different types of fire - based powers create an interesting power dynamic that many fanfictions play with. For example, how they could use their powers together or against each other in different situations.
A common plot twist is that Hermione actually has a hidden power or ability that she reveals during her captivity. For example, she might be able to use a type of magic that Draco and his associates didn't expect, which gives her an upper hand in the situation. This could lead to a change in their relationship dynamic, from captor - captive to something more like equals.
One common plot twist could be that the reader turns out to have a hidden power or connection. For example, they might be related to a powerful figure in the Marvel universe. Another twist could be that Bucky has been brainwashed by an unseen force to kidnap the reader, and as the story unfolds, he starts to fight against that control. Also, the reader might find out that Bucky's kidnapping was actually a misdirected attempt to protect them from a greater threat that he knows about but the reader doesn't.
The relationship between Dabi and Shouto is complex in the original My Hero Academia story. In the 'dabi saves shouto' fanfiction, it flips the expected dynamics. It could be interesting because it shows a different side of Dabi, perhaps a more heroic or caring side towards Shouto that we don't often see in the canon.
One popular dabi x shouto fanfiction is 'The Unlikely Bond'. It delves into the complex relationship between the two characters, exploring how they might interact outside of the main story's battles and conflicts.

Well, a really interesting plot twist could be that Pitch kidnaps Jack, but then realizes he has kidnapped the wrong 'Jack'. This could lead to a whole series of comical or tense situations as he tries to figure out what to do. Or perhaps when Pitch kidnaps Jack, Jack's friends don't immediately realize it's Pitch. They suspect someone else at first, which causes a lot of confusion in their search for Jack. Also, it could be that Pitch kidnaps Jack into a dream world where the rules are completely different, and Jack has to adapt quickly to escape.
Well, perhaps a plot twist could be that Percy's friends think he's been kidnapped by someone else entirely. So they're looking in all the wrong places while Khione has him hidden away. Or, it could be that Khione kidnaps Percy but then realizes she's made a huge mistake because Percy has some sort of connection to a force that can destroy her. So she has to figure out a way to either let him go or use him to her advantage in a different way. Also, what if Percy is able to communicate with the elements in Khione's domain and he uses that to his advantage to escape or gain the upper hand?
One possible plot twist could be that Bumblebee has a hidden power that he discovers while in captivity. For example, he might be able to communicate with an ancient Cybertronian force that helps him break free. Another could be that Megatron has a secret reason for kidnapping Bumblebee that has to do with an old prophecy. Maybe Bumblebee is the key to unlocking a great power that Megatron wants for himself.
