Fictional characters that perfectly display an MBTI type.

oh i totally agree on luna! i've seen her typed INTP, but i think INFP and enneagram 5w4 is more likely. ron ESFP - i'd say snape and voldy both INTJ (mayybe snape a particularly stodgy INTP) but dumbledore INFJ, with Ni much heavier than Fe.

i dunno, something about the whole thing seems more INFJ to me. how dumbledore wants to have wizards rule over muggles so that the way his sister was attacked would never happen to anyone again. maybe it's how hidden he keeps his logic - more Ti than Te - while quietly influencing people to meet his unspoken plans... kinda Fe-ish...

Yes, I can see Dumbledore either way. The true extent of his machinations only comes out in the later books. Is he an INFJ who eventually developed Te, or an INTJ who developed compassion and external sensitivity? One can actually make a decent case for Voldemort being INFJ, but I digress.

Peggy and Kelly Bundy: ESFP (no doubt in My mind).

Can't decide on Bud, either ESTP or ENTP. Maybe even ENTJ. (Obviously not a perfect display.)

And Al, either ISTP or ISTJ.

And Hermione is a Rational. No doubt a knowledge seeking personality. Either ENTJ or INTJ. Didn't see her as much of a security seeker, which means she's not a Guardian. Idealist is a possibility for her, too.

Married with childern is a show about a all P family, they're all very scattered and wayward. I think Peggy is more ESTP, I think she uses Fe to manipulate her husband, but Kelly does fit ESFP(negatively though). I think Bud is actually INTP but ENTP might fit, at first I thought Al was an ESTP(salesman) but he seems more like a grouchy, lazy ISTP.

ISFJ
Shiro Emiya (Fate Stay Night)

I consider him either an INFP or maybe INFJ.

If all else, Archer is more like the ISFJ, but that is because he becomes a servant of the people. And archer is the one who comes back to the past to the holy war wanting to kill Emiya because he was "naive" and was on a path of regret later in his life.

Considering how slightly different the manga is to the anime, anyhow.

I can think of other close fits, but these are a few that have struck me as exact:

INFP - Frodo Baggins (The Lord of the Rings)
ISFJ - Samwise Gamgee (The Lord of the Rings)
INTP - Stephen Maturin (Aubrey-Maturin Series)
ESFJ - Doctor McCoy (Star Trek)
