Uh, I hate to throw water on this, but I find that characters often don't fit MBTI archetypes. That's because those who write tha characters often don't know MBTI. So the character may have some character traits of one type and some of another. Or, they will exaggerated character traits. Like the taking the cleanliness and orderliness of ISTJs to an extreme.
I hate it when I see characters totally not fitting a type. And I get frustrated with that fairly often. The ESFP, for example, having the nobility and idealism of an INFP. Bah! They want their heros to have it all! And it doesn't happen that way in real life.
They really are sort of forced into it, I mean who wants to watch a roomfull of nerds reading and staring at a computer screen? Let's all give the poor writers of the world a break!
Yah, the "fluffiness" of INFP's is a huge misconception. I think a lot of the essence of INFP's is that they have a huge range of emotions and states... so if we are fluffy, we also have a darker edge, if we are funny, we are also intensely serious, if we are happy, we are also sad, and I think we generally feed off this kind of veriety and range, which I think is the reason some INFP's are known to almost enjoy being sad.
Just wanted to pitch in, carry on
I've actually heard it said that Laura Ingalls Wilder is an S, due to the vivid details in her stories.
I-I can't believe someone did that! I was thinking on doing it but thought nobody would know about them.
But I disagree on Sol and Ky. I think Sol is more of a P (he hates 'doing his best'), but since INTP doesn't fit him I'd say ISTP, and Ky is more of an E and T. For the others... The most archetypal are in my opinion:
