Here's a guide to fictional type clichés (is that with an accent in English?)
Rule #1: Feelers are always better than Thinkers. An F can be a bad guy, but only a T can be truly evil.
Rule #2: Extraverts are always dumber and less important than Introverts. An E can be a sidekick, but the hero is an I.
Rule #3: Sensors are always dumber than Intuitives. Intuition sees the world on a deeper level you know (this is not my opinion).
Rule #4: Perceivers are always better than Judgers.
Which results in:
ESTJ: bad, but too dumb to be really evil. A stick-in-the-mud boss who hinders the hero who wants to do things his way. Becoming an F can redeem this type.
ISTJ: guard, plumber... who gives practical advice, but never gets an important role. Despite the TJ combo this one can actually be good (but never good enough for hero or mentor roles)
ESFJ: the overbearing mother. ESFJs are always female. Well-meaning (she's an F after all) but, as a dumb E-S and an uptight J, hinders the hero in his quest.
ISFJ: nurse, physician... Well-meaning and caring, tries to hold the hero in the hospital when hero wants to get up and about.
ESTP: friend of the hero, tavern guest who divulges some information needed for the quest, grunt in the villain's army who can be bribed.
ISTP: no important roles, can play a part as weaponsmith.
ESFP: funny and dumb (of course *eyeroll*) sidekick. This (certainly good) one might defreeze and redeem the INTP.
ISFP: less cunning than the villain, the all-good FP combination, the FiNi angst: this is hero material.
ENTJ: evil emperor. Nothing can redeem this type.
INTJ: archvillain - as both I and N he's the smartest one around, and as both T and J the most evil. Nothing can redeem this type.
ENTP: being a P can redeem the T: an enthousiastic forgetful genius, can work either for the Good or the Evil side but is more interested in his own inventions than in good or evil.
INTP: the dork genius cooped up with computers (or the equivalent available in the setting), more seen as a failure than as a danger/ally, despite him being one of the smartest types. This type is redeemed by getting friends.
ENFJ: a cunning manipulator (if more J) or a loving teacher (if more F)
INFJ: wise IN, good F but falls back at the crucial moment due to J: mentor material here.
ENFP: another sidekick, funny and whimsical
INFP: shaman, true love of the hero... in all cases, this type tells the hero to 'follow his heart' and frees him from his angst.
Feel free to add more clichés
Just to be clear: it's not my intention to say all fiction writers should follow these rules. On the contrary. It's just an observation: most (not all, I know) fiction follows them... and choosing one of them to break (or all of them) can be a rich source of inspiration.
This amateur writer is mining it already... Yay for my new INTP hero!
