Ive got a proposal for another INFJ villain. How about Ultron from Marvels age of Ulton. The only thing I dont know about are the E and I he might be an extrovert over an introvert.
I can't think of any clear INFJ villains...
Possibly Erik Lensherr/Magneto and Phantom of the Opera? I can see them as INTJs too, though.
I've never seen a movie with Loki in it, but I think Saruman is INTJ.
In the prequels I think Charles is xNFJ 1w2, and Erik's INxJ 8w7, but I always felt like this was a badass INFJ speech.
There has to be more INFJ villains.
I loved Days of Future Past <3
Professor X in the earlier films reminds me so much of myself, so I definitely see XNFJ 1w2, as I am.
I'm sure there are more, but perhaps they're masquerading as other types. Or I'm just overlooking them. When I look at Erik's speech again, it reminds me of how I always got the NFJ vibe from Professor Xavier's 'evolution' speeches at the beginning of some of the X-Men movies. It's focusing on the human and moralistic view of evolution rather than the scientific that Erik leans to when he argues that humans are like the Neanderthal and mutants, the next step in natural selection. While it's not the complete picture, that comparison always makes me think it's X that is the INFJ and Erik the INTJ whose Fi is focused on staying true to his 'people' and caring deeply for them. While Xavier cares more about harmony for all, not just his own.
Erik always seems far harder to type but it's as though he's one side of the same coin as Xavier in their attitudes towards mutants/humans and it's very likely they're both the same type, just at either extreme.
I believe Itachi from Naruto is one for sure, no doubt in my mind. Pain also, but I could also see INFP for him so I'm not as sure. At least not from the movies, Loki does not strike me as an INFJ in any way, shape or form. It doesn't come across as debatable to me. He's far too energetic, he doesn't think before he speaks, he's leaning far more on the witty and scheming side than the intellectual necessarily and he has no emotional intelligence to speak of. There's no INFJ in him. Not in the movies at least.
By doing a quick google search, I was reminded by someone who once mentioned R’As Al Ghul to me and I completely get that on first glance and without actually trying to attribute functions to him. Out of live-action villains, he's perhaps the only plausible and realistic one I can think of.
