Asgore is another character. In fanfiction with SI, we could see the SI trying to understand Asgore's decision to collect human souls. The SI might try to find an alternative solution, or they could be caught in the middle of the conflict between Asgore and the humans. This could bring out new aspects of Asgore's character, such as his sense of duty, his love for his people, and his internal struggle with the violent nature of his plan.
It could also be a cultural or ethnic term in the fanfiction world. Fanfic writers often expand on the cultures in the Game of Thrones universe. So 'Si' might refer to a group of people, like a tribe or a clan, with their own traditions, languages, and ways of life. This can be used to introduce new conflicts or alliances within the story.
If the SI has a different personality trait, like extreme aggression compared to the mostly pacifist nature of the Undertale world. They could start fights with various monsters, causing a chain reaction. Monsters who were previously peaceful might be forced to defend themselves, leading to a shift in the power dynamics and the overall plot direction. Also, it could make some characters question their own pacifist beliefs.
One idea could be exploring an alternate timeline where Sans and Papyrus have different roles. For example, Papyrus could be the more serious and powerful one while Sans is more carefree. Another idea is to write a fanfic centered around a new character who gets trapped in the Underground and has to navigate through the various regions, making unique friendships along the way. And a third idea could be a fanfic that focuses on the backstory of the monsters before they were trapped underground, showing how their society was and how it changed over time.
One idea could be that Si, who was an ordinary person, suddenly gets transported into the game world and starts to gain OP (over - powered) abilities. For example, Si could have the power to control time within the game, allowing them to reverse bad decisions or speed up processes like leveling up. Another plot could involve Si being the only one immune to a powerful virus in the game world that is turning all the other characters evil, and they have to use their new OP powers to find a cure.
One interesting 'Si Game of Thrones fanfiction' could be one where a minor character gets a major role rewrite. For example, a servant in the Red Keep who becomes a key informant for a major house. They might overhear secrets and use that knowledge to shift the power dynamics in King's Landing.
Some fanfictions might focus on the reactions of the onlookers during the bedding ceremony. This can provide insights into the social norms and values of the 'Game of Thrones' world. The ceremony is often a public event, and the way people respond, whether with excitement or disgust, can tell us a lot about the society. For instance, if the common folk cheer while the nobles are appalled, it shows the divide in values between different classes.
One interesting plotline could be the power dynamics within the harem. For example, different characters vying for the main character's attention while also having their own political or personal agendas. Maybe a character from a minor house in 'Game of Thrones' uses her charm in the harem to gain influence over the more powerful lords.
One interesting concept is the self - inserted character changing the course of major events. For example, they might prevent the Red Wedding, which was a tragic and pivotal moment in the original series. This alteration can lead to a completely different power dynamic in Westeros.
No, in the game's lore, there's no indication that Undertale has the ability to watch fanfiction. The game world is focused on its own story and mechanics, and fanfiction exists outside of that official world.
The most interesting aspect could be the power dynamics. Si, as an OP character, would change the existing power balance in the DxD world. They could challenge the traditional powerhouses and create new alliances or rivalries.
