cross sans crossover fanfiction

One idea could be a cross with a classic fairy tale. For example, Sans from Undertale could be in a world where he meets characters from Cinderella. He could use his unique abilities to help Cinderella in a new and unexpected way. Maybe he uses his shortcuts to quickly gather all the things she needs for the ball or to outwit the evil stepmother.

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 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.

The popularity might be due to the contrast between the two characters. People are drawn to the idea of seeing how a 'dark' character like Nightmare Sans and a more 'conflicted' character like Cross Sans interact. It creates a lot of room for interesting scenarios.

One common theme is friendship. Since they are from different 'worlds' in the Undertale AU, their journey to become friends is often explored. Another theme is redemption. Sometimes Cross Sans might have a troubled past and Dream Sans helps him find a new path.

Power dynamics is also a frequent theme. Nightmare Sans is often depicted as very powerful, and Cross Sans has his own set of powers. Fanfictions might explore how they use or abuse their powers in relation to each other. It could be a power struggle, or they could end up combining their powers for some greater purpose.

One popular cross sans x dream sans fanfiction is 'The Meeting of Two Souls'. It beautifully depicts their first encounter and the development of their unique relationship. Another great one is 'Cross and Dream's Adventure' which takes them on an exciting journey through different AU's.

Papyrus also shows up often. His relationship with Sans adds an interesting dynamic to the crossovers. And his own unique personality and abilities can lead to various plot developments when combined with other crossover elements.

The theme of chaos and order also appears frequently. When Sans crosses over into other universes, it can disrupt the existing order or he might be the one to bring order to a chaotic situation. This creates interesting storylines as he has to navigate through these new power dynamics and relationships. Also, there can be a theme of redemption in some cases, where Sans helps a character who has made mistakes in their own universe.
