The prize always goes to the winner, right? And the winner, in most stories, is the good guy, the protagonist. He might get a vacation at a resort in Bermuda, or win a new EV, or even a shopping spree at a high-end store. We cheer for him, support him, and feel happy for him.
What if the antagonist receives the benefit? How does that change the story arc?
If the benefit is inside information that allows her to pull off a heist, is that a good thing? Or perhaps she wins a million dollars that allows her to escape capture and set up a new life in some far-off island?
Your task is to write a story in which the antagonist is the winner, the recipient of the prize. Make the benefit large enough to have a huge impact in the trajectory of events.
Have fun with this one.
