I've been thinking about using a prophecy in my series. Now I know the whole prophecy thing has been overdone, and little to no explanation is given about where the prophecy comes from, so I'm thinking of having a false prophecy. Essentially, we reach a point in the series where the main character is recognised for her heroic deeds. Her past is a mystery, as she has no memory of her biological parents. One day she is approached by a cult leader which worships her as the new saviour of humanity. She doesn't like the idea, as she already has religious beliefs and wouldn't dare think of herself as a messiah. However, as many cult leaders turn out, he has an ulterior motive. He leads his followers into believing he is her high messenger, and presents her with a prophecy he made up himself, using her past victories as examples of how his prediction is accurate. He makes a few predictions which come true, but he arranged the events in order to make her believe his story. While she isn't completely convinced, she starts listening to him. I won't go into the details of how it ends, but would this be a new way to use the prophecy trope?
