Thor / The Avengers
Te: Loki wants control –of everything. He’s a natural leader who takes control of people and situations, organizing them toward specific actions often without them even knowing about it. His thought process is logical and rarely deviates from his Ni plans long enough to get distracted by anyone or anything. Loki does everything with a specific purpose, always aimed towards results. Loki’s speech patterns are direct and often harsh.
Ni: Loki is good at predicting future outcomes based on present occurrences. He plans meticulously and long-term, and carries his plans out with precision. He naturally recognizes problems with his plans and is able to eliminate them as he works. Loki recognizes the weaknesses of other people intuitively and uses that knowledge to manipulate them. Loki is able to visualize his intended future enough that it seems like a definite reality to him.
Se: At times, Loki can overconfident in his plans, leading him to act impulsively and endanger those plans. He’s able to adapt to change on the fly, revising his plans as he sees fit, but at the same time, he hates surprises. When his plans are overturned, he doesn’t always know how to react.
Fi: Although Loki’s actions are precise and calculated, his primary motivation is always his feelings. He places himself above anyone else on a priority scale and doesn’t necessarily have a strong set of moral values (his Fi is pretty unhealthy).
Loki is often typed as INxJs, but function wise, neither one works. People assume INTJ because he’s relatively quiet and likes to keep to himself, but the loudness of a person is a poor substitute for looking at the functions when it comes to determining type.
Others assume INFJ simply because he’s a sympathetic villain. Fun fact, not every sympathetic person is an INFJ, and not all INFJs are incredibly sympathetic. INFJ villains are people like Adolf Hitler, who use their Fe to charm thousands of people into taking their point of view. When does Loki ever use charm and social skills to get people to follow him?
Fictional INFJ villains look more like Ras Al Guhl, who will become your mentor and friend, then turn around and stab you in the back.

That evil usage of Fe also reminds me of Regina George from Mean Girls, also an FJ.

Do you think it possible that Loki was an INTP in ‘Thor’ and because of trama-in between the movies-he switched to ENTJ?

Haha. I’d like to think so. I used to be an INTP, and I think perhaps due to traumatic situations I switched to ENTJ.

I think you typed Loki incorrectly.

Interesting. I don’t know enough about the Avengers to have come up with something like that. At the same time, I don’t see how it particularly disproves my typing of him as an ENTJ.
*sigh*
If only I had time to read every single theory tumblr puts out and concoct an opinion which would ultimately satisfy the greatest number of obsessive fans world wide…no such luck.

“Lastly, don’t make the mistake of typing a character purely based on behaviour without also considering their motivations.”
I believe the character to be an INFJ.

Loki seems fairly charismatic ( or at least he seems to think he is) – he’s always making grandiose speeches, appealing to people’s nature and emotions, but making points that don’t add up logically (“Free from what?” “Freedom”).

I know a large quantity of ENTJs that think they’re very charismatic and like to make grandiose speeches mainly because they want to witness the affect it has on people (tertiary Se). Loki doesn’t use charisma to “appeal” to people’s emotions, he uses it to scare and/or manipulate them into doing what he wants, which is completely different from charming people into listening.
Just because someone’s a T-type doesn’t necessarily mean they’re “better” at logic – just that they favour the use of it over emotion. An xNTJ can make emotional arguments too –trust me, you’ve got to if you want to survive in a world full of feeling people.

In Thor when he said he was the “monster parents tell their children about at night,” it was because he was taught to believe Frost Giants were monsters.
