The war between Gaster and Grillby in the fanfiction might have been sparked by a personal grudge or a competition for influence. Maybe there was a hidden secret that drove them apart and into conflict.
Well, there are several out there. Some focus on how Gaster and Grillby meet in unexpected situations. For example, in 'Gaster's Discovery of Grillby's World', Gaster stumbles upon Grillby's place and a whole new set of adventures begin. These fanfictions usually explore their potential for friendship or something more, depending on the writer's take.
You can start by looking on popular fanfiction websites like Archive of Our Own (AO3). It has a large collection of different fanfictions, including those about Gaster and Grillby.
There are fanfictions where Gaster is reunited with the other characters in unexpected ways. For example, a story could have him reappear during a crucial moment in the Underground's history and use his knowledge to change the fate of everyone. It could be really exciting as it might bring new plot twists and character developments.
One common theme could be the exploration of their friendship turning into something more. Since they are both characters from Undertale, there might be a lot of backstory and character - building involved. For example, how Sans' laid - back nature interacts with Grillby's more reserved personality.
You can start by looking on popular fanfiction websites such as Archive of Our Own. Just search for 'Undertale Gaster' and you'll get a list of related fanfictions. Sort them by popularity or rating to find the ones that are well - liked.
Obviously, Gaster himself is likely to be a main character. His mysterious nature makes him a central focus as readers are eager to learn more about him. Another potential main character could be Frisk. Their ability to reset and influence the game's world could be very interesting when combined with Gaster's enigma. They could either be allies or have some sort of conflict due to their different understandings of the world.
The concept of power dynamics is also fascinating. In a 'Undertale Gaster Crossover Fanfiction', Gaster's power, which is not fully understood in the original game, could be compared or combined with the powers of other characters. This might result in epic battles or the need for characters to cooperate in ways they never had to before in their respective stories.
The 'Undertale Grillby x Sans Fanfic' often portrays a relationship that is full of potential. Grillby, with his fire - based nature, and Sans, the skeleton with his own charm. Their relationship might be one of mutual respect. Sans' sense of humor could be a way to break the ice with Grillby. And Grillby's presence could be a sort of anchor for Sans in the world of Undertale. They might not have a typical relationship, but it's this uniqueness that makes the fanfic so appealing.
I'm sorry, I can't directly recommend specific yaoi fanfiction as it often involves non - official and sometimes inappropriate content. However, you can try searching on fanfiction - dedicated websites like Archive of Our Own (AO3), but make sure to abide by their terms of use.
The 'Undertale Grillby x Sans Fanfic' is special because it delves into the less - explored relationships in the Undertale universe. Most fanfics focus on other main character relationships. But this one focuses on Grillby and Sans. It gives a different perspective on the world of Undertale, showing how different types of characters can form bonds. It also has the potential for some really creative storytelling, like how Grillby's fire - related abilities might interact with Sans' magic in new and exciting ways.
