They could interact in various ways. For example, they might form a spiritual bond and communicate telepathically. In some fanfictions, they might influence the actions of the main characters like Frisk or Chara.
The six human souls are central, but we might also see some new characters created specifically for this fanfiction. These new characters could be there to help or hinder the six human souls in their journey through the Underground. They could bring in new plotlines and add more complexity to the story.
Well, obviously the six human souls are main characters. Each of them has their own unique characteristics. There's the soul of determination, which is often associated with strong willpower. And then there are others like the soul of kindness, which might be portrayed as more empathetic.
One interesting concept could be the exploration of the unique powers and personalities of each of the six human souls. They might be depicted in ways that expand on what we know from the original Undertale game, like showing how their traits interact with the Underground world in new and unexpected ways.
One interesting aspect could be the different interpretations of the six human souls. Maybe some fanfictions focus on their backstories before they ended up in the Underground. For example, a story might explore how they got their unique traits that are associated with their souls.
Well, one possibility could be that the six human souls somehow break free from their captivity within the game's lore. They might then team up with the monsters in the Underground to find a way to co - exist peacefully. Maybe they use their combined powers to change the rules of the Underground, allowing for a more harmonious relationship between the two races.
One interesting fanfiction could be where the six human souls have the ability to communicate with each other in the afterlife within the Underground. They share their memories and experiences, which gives a deeper understanding of each soul's nature.
Definitely the six human souls are central. But there could also be a new character created specifically for the fanfiction. Maybe a hybrid of a monster and a human (a concept that could be explored in this fan - made story) who has a deep understanding of both the human and monster worlds. This character could help the six human souls navigate the Underground and understand their place in it. Additionally, Flowey could be a main character as well, his complex relationship with the human souls adding an interesting layer to the story.
The way the six souls were collected in the Undertale comic is full of mystery and adventure. Different characters play crucial roles, and there are hidden clues along the way.
It depends on the specific fanfiction, but often the six characters who possess the human souls are the main focus. They could be ordinary people thrust into extraordinary circumstances because of their souls.
