This spreadsheet will help you assign personality traits to your characters.
Instead of giving you a genre-related character and a situation, it gives you type of character and style of story to write. The characters and plots are based on tropes from TV Tropes.
For instance, you might get an outline to write a story about a Plucky Girl with a lisp who uses an Artifact of Doom against a Brute. The plot will hinge on her Right-Hand Dog and the story should use the Conflict structure.
Within those constraints, you decide what the story is about. It could be a fantasy, a mystery, or even a romance story.
