One common plot twist could be that Koga actually kidnapped Kagome to protect her from a greater threat. Maybe there's a powerful demon that's after Kagome, and Koga, despite his rough ways, believes he can keep her safe. Another twist might be that Kagome discovers she has some hidden power while in Koga's captivity that helps her either escape or gain an understanding of the demon world in a new way.
A possible plot twist is that Koga's tribe turns against him because of the kidnapping. They might think it's a bad move that will bring trouble from Inuyasha and his allies. This forces Koga to make a difficult decision - either let Kagome go to save his tribe or keep her and face the consequences. It adds an extra layer of drama to the fanfiction story.
Often, there could be a love triangle aspect added as a plot twist. While Koga has kidnapped Kagome, Inuyasha might come to her rescue. But during her time with Koga, Kagome starts to see a different side of him and questions her feelings for both Koga and Inuyasha. This creates a complex emotional situation for all the characters involved.
One plot twist could be that Inuyasha tries to win Kagome back at the last minute. He realizes he truly loves her when he sees her about to marry Koga. This would create a lot of drama and tension between the three characters.
The plot could twist when they find out that Kagome's pregnancy is progressing at an abnormally fast rate. This could be due to her connection to the feudal era and the different time - related magic there. It might also be that the baby has some special powers that are causing this rapid development. Additionally, there could be a plot twist where Koga's pack has different reactions to the pregnancy. Some might see it as a sign of weakness, while others see it as a new beginning for the pack.
At first, Kagome is likely to be angry. She's a strong - willed character, so being kidnapped goes against her nature. She would probably struggle and try to escape immediately, yelling at Koga about how wrong his actions are.
Another theme is adventure. Given that they are both part of a world full of demons and magic, fanfictions often send them on exciting quests together. For example, they might go on a journey to find a powerful artifact or to defeat a new evil that has emerged. This not only tests their relationship but also shows their individual strengths.
Another theme is the struggle for acceptance. Koga is a wolf demon and Kagome is a human with her own set of values. Their different backgrounds lead to a struggle where they have to accept each other's differences in these fanfictions. For example, in many stories, Koga has to adapt to Kagome's human emotions and she has to understand his demon nature.
One common theme could be family. Since it involves a baby, it might explore how Koga and Kagome adapt to being parents and creating a family unit.
Perhaps in the fanfiction, Koga kidnaps Kagome believing she has some special power that can help his wolf demon tribe. He might think that she can heal the sick among them or bring good fortune to their land. However, Kagome doesn't actually have this power, and she has to convince Koga to let her go while also trying not to anger him too much. As she's held captive, she might learn more about the wolf demons and their way of life, which could be an interesting aspect of the story.
One common plot twist could be that the kidnapper is someone they least expect, like a close acquaintance with a hidden agenda. Another might be that Bughead discovers a secret about their captors during the kidnapping that changes the whole situation.
One common plot twist could be that the kidnapped person discovers they have a special power or connection to the vampire world that the vampire didn't expect. For example, they might be able to resist the vampire's mind - control powers more than others. Another twist could be that the vampire who kidnapped them is actually being controlled by a more powerful and evil entity. So, instead of being the main villain, the kidnapping vampire becomes an ally later on. And sometimes, the kidnapped person turns out to be a long - lost relative of the vampire, which completely changes the dynamic between them.
A plot twist might be that Sokka's kidnapping was part of a bigger plan to draw out other important characters. For example, his friends come to rescue him and end up walking into a trap set by the kidnappers.
