They might be really intrigued. Ruby, with her love for adventure stories, would probably be excited to see the unique worlds and characters in the fanfiction. Weiss might be a bit more critical at first, analyzing the writing style and how it adheres to the original Undertale lore. Blake would likely be interested in the deeper themes and character relationships presented in the fanfiction. Yang, on the other hand, would enjoy the action parts and cheer on the characters during intense scenes.
Glitchtale Fanfic is fan - made fiction related to Glitchtale. It often features unique storylines, character developments, and interpretations that are different from the original Glitchtale. Fans create these fanfics to explore new ideas, relationships between characters, and sometimes to expand on the Glitchtale universe in ways they would like to see.
If it's a comedy - based fanfiction, the character might be laughing out loud or at least have a big smile on their face. They'd be enjoying the humorous take on their world. For a more serious, angsty fanfiction, they could be feeling solemn or even a bit sad, especially if it involves difficult situations for their friends or themselves.
You can find Glitchtale Fanfic on various fan - fiction websites such as Archive of Our Own (AO3) or FanFiction.net. These platforms have a large collection of fan - made stories, including those related to Glitchtale.
One possible plot could be that the characters from Glitchtale end up in the world of Percy Jackson. Maybe Betty, from Glitchtale, could be mistaken for a new type of monster by the demigods. The demigods then have to figure out whether she's a threat or not. And at the same time, the Glitchtale characters are trying to find a way back to their own world.
Ink!Sans is a popular pick. His creative and somewhat unpredictable nature can bring a lot of color (literally and figuratively) to a Glitchtale crossover. He could use his paint powers in the Glitchtale world in ways that no one expects. Also, Bete Noire from Glitchtale is a character that many fans like to include. Her relationship with other characters, especially her sister, can be explored in new and interesting ways when in a crossover situation.
One idea could be a crossover with Undertale. The characters from Glitchtale could interact with the original Undertale characters in a new and unexpected way. For example, Betty from Glitchtale could team up with Chara from Undertale for some sort of dark plan. Another plot could involve a crossover with a different game like Minecraft. The Glitchtale characters could find themselves in a blocky world, having to adapt to new rules and enemies. Maybe Sans from Glitchtale could use his powers in the Minecraft world in a really creative way.
One idea could be that the Glitchtale characters are transported to the Avengers' universe. Sans could use his shortcuts to surprise the Avengers, and Betty could be a powerful villain they have to face together. Maybe Papyrus befriends Thor because of their similar jovial natures.
Well, if Undertale could watch Undertale fanfiction, it could lead to some chaos. For example, Sans might make jokes about the wild scenarios in the fanfics. Papyrus, on the other hand, might be eager to correct any misinformation about himself. And Flowey could use it as a way to manipulate things further, seeing how the fans view the characters and using that knowledge to his advantage in this strange, meta - situation.
Some characters might be amused. For example, Sans would probably make some witty remarks about the fanfiction's plot twists. Papyrus, on the other hand, might be a bit confused at first but then get really excited if he finds a heroic role for himself in the fanfiction.
