HEATHEN! WAAAAAAAGH!

No, go ahead. If someone disagrees with an entry deletion we can deal with that later, but it shouldn't be a big deal.

I know what these "temperaments" are but I'm trying to understand how they apply to characters. I think there's still a lot that don't fit. What is the best example?

I kind of agree, I don't think the problem is the trope though, I just think the site is missing alternate versions of a group of four ensemble. For instance we have tons of versions of Power Trios but we somehow only have one for a group of four?

EDIT: just created the Four Philosophical Ensemble, a new group of four trope that may fit some groups better, in the YKTTW here: http://tvtropes.org/pmwiki/discussion.php?id=oenebf5w9rj3cqqw1dl5kvgo

Seeing as the Four Humors-type is just a graph with extroversion-vs-introversion on the y-axis and goal-oriented-vs-people-oriented on the x-axis, it's almost omni-present as a characterization trope. In my experience, a character designed simply to seem real can often be fit into this chart after the fact. A character would have to be flat (which falls in the expanded chart anyway) or completely alien to avoid falling somewhere on the chart.

I propose that this page be exclusively for cast of four-to-five, designed to fill one type each. But that works with well-defined character personalities could link back to this page from their character sheet.

tl;dr — This page, just for groups designed to fit this. Large casts link to this as a Useful Notes page from character page.

I'm not sure that the four humors apply to characters at all. The one used for the quote, Teenage Mutant Ninja Turtles works well for two or three out of the four of them as there's The Hero Leonardo (Choleric), The Smart Guy Donatello (Melancholic), the good side of Sanguine is Michelangelo and the flip side of it is Raphael (The Big Guy), but no one is the calm and compassionate Phlegmatic. Am I missing something or is there an example that works better?
