A couple new, obscure ones....
John Laroquette's character(who wakes up temporarily from a coma) in that one episode of House: ENTJ
INTPs are much more often depicted as nerds, eccentrics, or absent-minded professors than as villains, but I may have found at least one INTP quasi-villain:
Remember that dumb, but hard to look away(the theme of the film, actually) movie Sliver? I watched it(random collecting via torrents) for the first time in 15 years this weekend(mild spoilers follow). I think William Baldwin's character was an INTP! Think about it: spends lots of time alone observing others through that system of monitors and cameras, designs video games for a living(as a cover, at least).
He must have great Ne to get all that play, though. Shadow Fe shows through his willingness to use his weird little setup to do some good, and his seriously fucked up and drawn out into the late 20s oedipal complex.
The other characters:
Jack: XSTP
Carly: IXXJ
Vida: ESFX
