What are some interesting cross sans crossover fanfiction ideas?

A 'seraphim sans crossover fanfiction' could involve a crossover with a space - opera setting. Imagine Seraphim Sans traveling through the galaxy, meeting different alien species and getting involved in interstellar politics. His character would add an interesting dynamic to the high - tech and often morally complex world of space - opera. He might be a key figure in a war between different star empires or help broker peace.

One idea could be a crossover where Sans from the game enters a human world during a major historical event like the Industrial Revolution. He could interact with inventors and workers, his magic and unique personality causing all sorts of comical and thought - provoking situations.

First, decide which two universes or characters you want to cross with Sans. This is crucial as it will set the tone and direction of your story. Then, do some research on both. If it's a crossover with a game or a book you're not familiar with, make sure you know the basic rules, settings, and character traits. For example, if it's a crossover with a Final Fantasy game, understand the magic system and the different races.

One interesting sans crossover fanfiction could be where Sans from Undertale crosses over with the world of Harry Potter. He might use his unique abilities like teleporting to surprise the wizards in Hogwarts. Another could be a crossover with the Pokémon world, where Sans teams up with Pikachu. Maybe he'd use his bone attacks along with Pikachu's electric shocks to battle villains.

One aspect to consider in this fanfiction could be the unique dynamic between Nightmare Sans and Cross Sans. Their personalities are quite different. Nightmare Sans is often associated with negative emotions and a more menacing presence, while Cross Sans has his own complex backstory. In the fanfiction, they might interact in ways that explore themes of redemption, power struggles, or unexpected alliances.

A plot could revolve around an accident that causes their universes to merge partially. Underfell Sans and Sans find themselves in a strange new reality where they have to figure out how to get back to their own universes. Along the way, they learn about the differences and similarities in their lives, and this leads to some really interesting character development.

One idea could be exploring the backstories of minor characters. For example, you could focus on the character of Radius and create a story about his life before he joined the Acacia Dragoons. Another idea is to create an alternate ending for the game. Maybe in your fanfiction, the characters are able to prevent the destruction of the world in a different way than in the original game. You could also write a fanfiction that focuses on the relationship between Serge and Kid, and how it develops further after the events of the game.

One interesting idea could be a crossover with "Moana". Elsa's ice powers and Moana's connection to the ocean could create a really cool dynamic. Maybe Elsa accidentally freezes part of Moana's ocean and they have to work together to fix it. Another could be with "Tangled". Rapunzel's long hair and her adventurous spirit combined with Elsa and Anna's journey in Frozen 2 would be exciting. Rapunzel could use her hair to help them climb mountains or cross chasms. A third idea is a crossover with "Beauty and the Beast". Belle's love for books and knowledge could help Elsa understand more about her powers and the history of magic in the Frozen world.

One interesting concept could be how Sans' unique abilities from his original game would interact with the RWBY universe. For example, his teleportation might be a new and unexpected skill in RWBY battles. Another concept could be the character interactions. Sans' laid - back personality could create some really fun and comical exchanges with the more serious or energetic RWBY characters like Ruby or Weiss.

One interesting concept could be the clash of different universes' rules. For example, when Sans from the Undertale universe meets characters from other crossovers, the way their powers interact. Sans' unique abilities like teleporting and bone attacks might be affected by the new environment or powers of the crossover characters.
