In yaoi fanfiction involving Tony Stark and the Soul Stone, it could be a very creative exploration. Writers might imagine unique relationships where the power of the Soul Stone somehow intertwines with Tony's character. Maybe it creates a deep emotional bond between him and another character in a romantic or soul - connecting way that goes beyond the normal MCU storylines.
In a Peter Parker - Soul Stone fanfiction, the Soul Stone could give Peter new powers. For example, it could enhance his ability to sense danger even more, or it could allow him to communicate with the souls of those he has lost, like his Uncle Ben. This would add a whole new layer of depth to his character and his story.
The soul stone usually has the power to manipulate or interact with souls. It might grant abilities related to soul control, resurrection, or even soul trapping.
A plot could involve Tony being the Soul Stone in a more metaphorical sense. For example, his intelligence and self - sacrifice are seen as the qualities of the Soul Stone. The story could show how his actions and decisions are like the power of the Soul Stone, influencing the fate of the other characters. He might sacrifice himself in a way that is similar to how the Soul Stone was used in the original story, but in a more emotional and character - driven way.
Yes, there might be such a fanfiction out there. Fanfiction often explores dark and alternative storylines. However, it can be quite a controversial and dark concept as Tony and Peter have a mentor - mentee relationship in the mainstream Marvel stories.
In fanfiction, Tony Stark may be linked to the Soul Stone in a way that it affects his character arc. The Soul Stone could represent a temptation for him. Given his complex personality, the power of the Soul Stone might either corrupt him or make him a better hero. It could also be that he is the only one who can resist the dark side of the Soul Stone's power, and this makes him a crucial figure in the fanfiction's plot related to the stone.
