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.
In a pitch kidnaps Jack fanfiction, a plot twist could be that Pitch kidnaps Jack, but Jack is actually in on it. They have a secret plan to deceive the other Guardians.

Another plot twist could be that Pitch kidnaps Jack, but during the kidnapping, they accidentally cross into a parallel universe where their relationship is completely different.

One possible plot twist could be that Pitch kidnaps Elsa not for his own gain directly, but to use her as a bargaining chip with the other guardians. For example, he might demand that the guardians give up their powers in exchange for Elsa's safe return. Another twist could be that Elsa discovers a new power within herself while being held captive by Pitch. Maybe her fear and the dark environment somehow unlock a power that is related to shadow or ice in a new way. And a third idea is that Pitch kidnaps Elsa because he realizes that her powers are a key to unlocking a greater power source that he wants to control, but Elsa manages to resist his attempts to use her in that way.
Jack could use his ice powers to create a distraction. For example, he could make a large ice structure that startles Pitch and gives Jack a chance to run. Another way is if he can find Pitch's weakness. Maybe Pitch is afraid of a certain light or sound, and Jack can use that to his advantage to escape.
A third plot twist could involve a character we least expect coming to Harry's rescue. Perhaps a Slytherin student who has been secretly against Voldemort all along.

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?

Well, in a Dracula kidnaps Mina fanfiction, it could go like this. Mina's friends might think she's dead at first. But then they start to notice strange things around town, like an increase in bat activity. They realize Dracula has taken her.

One possible plot twist could be that Aizen has a hidden motive other than just causing chaos. Maybe he kidnaps Ichigo to use his unique powers for some sort of experiment.

Another twist could be that Aizen is being controlled by an even greater force, and Ichigo's kidnapping is part of a larger plan to draw out other powerful characters in the Soul Society.
Another aspect could be that the Kyuubi is being controlled by a hidden force when it kidnaps Naruto. This hidden force might be using the Kyuubi's power to start a war between the village and other hidden villages.

Naruto might then have to figure out a way to break free from the Kyuubi's hold and expose the real villains behind the kidnapping.
In a Toga kidnaps Midoriya fanfiction, the plot could go in various directions. Maybe Toga kidnaps Midoriya to trade him for something she wants from the heroes, like the release of a fellow villain. Midoriya, on the other hand, could try to escape by using his wits and his knowledge of Toga's weaknesses. For example, if he figures out that she has a soft spot for a certain type of person or situation, he could use that to his advantage. Also, the story could involve the other students at U.A. trying to rescue Midoriya. They might come up with a clever plan that involves using their individual quirks in a unique way to outsmart Toga and get Midoriya back.
