Well, it could be about a new adventure in the Undertale world with this so - called ninth human. Maybe they have unique powers or a different backstory compared to the other characters in the original game.
Here are some plot ideas. First, the adult human could be a scientist. They meet Toriel and start to analyze the magic in the Underground. As they collaborate, they grow closer. Second, the human might be a storyteller. They tell Toriel tales of great heroes and adventures from the surface. Toriel is so captivated that she wants to be part of those stories with the human. Third, the human has a troubled past. Toriel, with her motherly nature, helps the human heal. Through this process, their relationship blossoms. In all these ideas, their relationship can develop in a non - sexual, deep and meaningful way, exploring themes of friendship, understanding and hope.
Often, the new human with a mysterious backstory tends to be popular. Their mystery draws readers in as they try to figure out who this character really is and what their motives are. For example, a new human who has no memory of their past but has strange powers.
One idea could be that the OC human is a lost traveler in the Underground. Toriel discovers the human and decides to take them under her wing. The fanfiction could focus on the relationship that develops between them as Toriel teaches the human about the Underground's ways and they share heart - to - heart conversations.
The main characters would include the ninth human, who is likely to drive the story forward. Then there are the monsters that the ninth human encounters. Sans could be a main character as he often has a deep understanding of the situation in the Underground and his interactions with the ninth human could be crucial. Papyrus, with his cheerful and naive nature, would also be an important character as he might befriend the ninth human easily. Toriel, being a motherly figure, could also play a major part in the story, perhaps trying to protect or guide the ninth human.
Well, the new human is obviously a main character. They bring a fresh perspective and set of actions into the world of Undertale. Then there are likely to be some of the well - known monsters like Sans and Papyrus. Sans with his laid - back yet mysterious nature, and Papyrus with his over - the - top enthusiasm. They often interact with the new human in various ways, creating interesting storylines.
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.
One interesting idea could be exploring new character backstories. For example, delving deeper into the lives of the new human characters before they arrived in the Underground. Maybe they had unique families or past experiences that shaped their personalities in the fanfiction world.
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.
