Characterization is key. Sans has his own distinct traits, like his humor and laid - back attitude. In a sans x ffism fanfic, these traits need to be maintained while also showing how he interacts with the ffism elements. Another important element is the plot. It should be engaging and have a clear goal or conflict. For example, they might be on a quest to find a lost artifact.
First, understand the characters of sans and the concept in ffism. You need to research their personalities. For sans, he's often seen as laid - back but with a depth of mystery. Then, think about a unique plot. It could be an adventure where they team up against a common enemy. Make sure to add some emotional depth to their relationship in the fanfic.
One key element could be the visual transformation. The Gaster Blaster Sans might change in appearance, with his blasters taking on new forms or emitting different colors. Another aspect could be the power boost. Maybe his attacks become more powerful or have new effects. Also, the emotional state during the transformation can play a role. Is he enraged, desperate, or something else that triggers this change?
One characteristic could be the unique blend of the horror and lust elements from the two 'sans' characters. It might play with the contrast between the spooky or menacing nature of horror sans and the more sensuous or alluring aspects of lust sans.
One popular sans x sans fanfic could be those that explore their unique friendship in different AUs (Alternate Universes). For example, some might focus on how they interact during a time of crisis in the Underground. Another type could be the ones that delve into their shared experiences and how they support each other through hardships. There are also fanfics that might take a more comical approach, showing their humorous banter and silly antics together.
Trust is an essential element in Sans' love story. Given his world and the things he has to deal with, he needs to be able to trust his love interest completely. And mutual respect for each other's boundaries, as he has his own way of doing things and his own space that his love interest would need to respect.
The key elements include his relationship with Papyrus. They are brothers and their interactions are a big part of Sans' story. Also, his laid - back nature is an important element.
A good one often has well - developed characters. Since Blueberry Sans is usually portrayed as positive and Fell Sans as more edgy, showing how they interact and influence each other in an interesting way is key. For example, Blueberry's optimism could start to rub off on Fell Sans.
Characterization is key. A good fanfic should accurately portray the personalities of both Underswap Sans and Underfell Sans. Their unique traits, like Underswap Sans' more positive and friendly nature compared to Underfell Sans' tougher exterior, should be well - presented.
One common theme is friendship. Despite their differences from different AU's, they often form a unique bond.
One common theme is the struggle between good and evil, as Dream Sans is often associated with positive aspects and Nightmare Sans with negative ones. Their relationship in fanfics can explore how they deal with their opposing natures.
