Perhaps in the fanfiction, the Soul Stone was hidden within Tony all along, and it was a key part of his origin that he never knew. As the story progresses, villains learn about this and try to extract the Soul Stone from him.

He could also discover that the Soul Stone has the ability to bring back a lost loved one, which adds another layer of conflict and emotion to the story.
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.

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.
