Well, it could be really interesting. Maybe it shows a unique interaction between Chara from Storyshift and Sans from Undertale. Their personalities are quite different. Chara can be rather complex and Sans is known for his laid - back yet perceptive nature. So in the fanfiction, there might be a lot of unexpected exchanges and development of their relationship.
Another plotline could be that there is a rift in the multiverse, and Chara and Sans are brought together to fix it. Along the way, they discover things about each other's universes and themselves, and in the end, they manage to close the rift and return to their respective worlds with a new understanding of the multiverse.
Another scenario could be that there's immediate conflict. Sans might suspect that this different - looking Chara has some malicious intent towards his world or his friends. So he could start a fight right away. But as the encounter progresses, they might start to understand each other better and the fight could turn into a more of a philosophical debate about the nature of their respective worlds and the actions they've taken in the past.
Underswap Chara could develop a sense of respect for Sans. Sans is known for his power and intelligence in the Undertale world. Through their interactions, Chara might see that there are different ways of handling situations than what they're used to in their own world. They could learn from Sans' more laid - back approach and start to adopt some of his non -chalant attitude towards things. This could lead to a more mellow version of Chara in the fanfiction.
