In my opinion INTJs are villains. As seen in most movies, books, the antagonist is the one who is socially detached, mysterious, mad scientist, creepy girl in horror stories, someone who has a superb knowledge in one area. He could also be an ENTJ who wants conquering the world.
And the heroes in my opinion, usually are the SFJ types. I think superman is ISFJ. Introverted-not really mingling with many people, Sensor-he has a heightened senses like flying, spped, super strength that uses his motor skills, x-ray vision (sense of sight), sonic ear (heightened sense of hearing). He is an F because he has care for people around him and puts everybody's safety above his own. And a J, because he's an achiever, and makes sure that he saves everybody on time, and does not procrastinates.
Any other ideas fellow PerC members?
