Which MBTI types prevail in your stories? Which is the hero, which the sidekick, the villain...?
Story #1: Hero ESTJ, villain ENFJ. No real sidekick, but a "band of adventurers" consisting of the ESTJ, another ENFJ, an INFP, an ENFP and an ESFP.
Story #2: Heroine ESTJ, sidekick ISFJ, archvillain INFP, evil emperor ESFJ (I like that one).
Story #3: Hero INFP, sidekick INFJ, damsel in distress ESTJ, villain INFJ. And a jester ENTP with a far too dominant Ne for comic relief.
