The key elements of Sans' life story are multiple. Firstly, his family bond with Papyrus, which is full of humor and care. Secondly, his knowledge of the timelines and the game's secrets. This gives his character an air of mystery. Thirdly, his interactions with the player character. Depending on the player's actions, his responses vary, which adds depth to his story. Also, his place in the Underground society, with its own rules and hierarchies, influences his life and actions.
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.
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.
One key element is the sense of despair. It's likely that he faced something that made him lose hope, which led to his violent ways. Another is the AU environment. If it was a harsh and unforgiving place, it could have pushed him to become a killer.
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.
The interactions between Sans and the characters from the other crossover element are very important. For example, if it's a crossover with a fantasy world, how does Sans interact with the magic - using characters? Does he use his own unique skills to complement or contrast with them? Another aspect is the world - building. How well does the author create the new combined world? Is it believable and immersive?
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?
Sans, in the Undertale universe, has a rather complex life story. He's a sentient skeleton residing in the Underground. He seems carefree on the surface, always cracking jokes and being lazy. But he has deep - seated knowledge about the game's world and its mechanics. His bond with Papyrus is central; he often teases his brother yet also looks out for him. He plays a crucial part in the player's journey through the Underground, whether it's in battles or interactions. His unique personality and his ability to remember things across different timelines add layers to his life story.
As I don't know shmateo, I can't determine the key elements in his life story.
Another element could be transformation. Shine might have gone through a significant change in their life, whether it was a change in career, attitude, or lifestyle. This transformation could be a central part of the story. For example, if Shine was once a shy and introverted person, but through certain experiences, became confident and outgoing. This kind of radical change can make for a very interesting life story.
One key element is vulnerability. In a life and trust story, someone usually has to be vulnerable, like the person who needs to trust another in a difficult situation. For example, when a person is sick and has to trust a doctor they've just met. Another element is integrity. The person being trusted should have integrity, like in the story of the lost wallet where the old man could have taken the money but didn't. And finally, there is growth. Trust often leads to growth, either in a relationship or in a personal way. For instance, in the story of the friends Tom and Jerry, their friendship grew stronger through trust.
Another important element is change. For example, a person might change their attitude towards a problem. In a story of a man who was always angry, he changed to be more patient after going through a difficult time. This change is what leads to the healing. It could also be a change in lifestyle, like starting to exercise which heals both the body and the mind.
