First step is to take the Myers-Briggs Type Indicator (MBTi) test and find out your result. Then you correspond your result to the chart and see which character you are most like from the show based on it! The results are not always going to be 100% accurate to the character and you may not be accurate to the result sometimes, but that's just how things go. The majority of the time, they are rather accurate.
Tell me what you think of it and just know that I'm not changing anything
EDIT 1: mypersonality.info provides a very nice test for you to do. I'm tired of people asking where to take the test... It requires a login, but it's free and one time only.
It's funny though, because I'm actually writing my own novels at the moment, and more by accident than on purpose, I've created the main protagonist casts' character more like mine (INTJ), and the villain more like something of an extremely depressed ENFP of some sort. XD I just hope normal people won't be cocking their heads at the thoughts and actions of my characters when they read about them.
I'm of the opinion that Sokka is an introvert and Suki an extrovert, and I would not be surprised if Katara were also an introvert. I think Sokka uses Ne more than Ni, which would make him an xNTP, rather than an xNTJ. Sokka is full of ideas, and if one is shot down he'll quickly pull out another to replace it. He prefers musing aloud over his ideas, bouncing them off of others. I believe he uses Ti more than Te. When he receives information, he likes to break it down and analyze it thoroughly before acting on it. He enjoys dissecting and reassembling things. And when tired, Sokka seems to prefer wandering off by himself to relax rather than look to others for energy. He doesn't express a great need to be involved in everything that others around him are doing, suggesting that he gets more energy from an internal source than from an external one. I think Sokka is an INTP.
Toph is decidedly not an extrovert. People stress her out very easily. Though she enjoys competing and bossing others around, she never sticks around after a match or a lesson. She always retreats to her own little haven of solitude. Toph enjoys confrontation but can only handle it for so long before she has to seek refuge from others. Toph is a very strong introvert; possibly the strongest of the introverted characters after Zuko. This isn't a result of her upbringing. She would have been an introvert even if her parents had given her all the freedom in the world.
The only Avatarverse character that I'm fairly certain matches my type is Jinora. She seems to use Fi as her dominant function, and has shown absolutely no signs of using Se as her auxiliary. Which means she must use Ne instead, making her an INFP. INFPs love their books and tend to have Input as a top strength. The INFP is known as the dreamer, healer or idealist, and Jinora certainly fits those descriptions.
It's when alone that she begins to fall apart. She doesn't do well when left to her own mind, as true introversion would suggest. And I would argue she utilizes Te more often than Ni, if one is to delve that deeply into it. Simply put, if you were to compare ENTJ and INTJ characterizations side by side, Azula will invariably fit the ENTJ model better. I've done this on numerous occasions without fail. She's arguably a very warped ENTJ.
Iroh is great at being around people as well, but he's definitely an I, rather than an E. He values his alone time to think and reflect. Remember, Azula only gets her energy from people as long as everything is going to plan. We saw what happened when things got messed up.
Personally, if anything, I think Azula is best labelled as XNTJ, because she rides so close to the line between I and E.
Well my reasoning for putting Azula in that spot is her functions Ni (Introverted Intuition) and secondary function Te (Extraverted Thinking). Ni functions allow a person to see the possibilities in the world around them and develop on point responses to problems with rather unique solutions. This is Azula's specialty. She is a MASTER at adaptation and it's nearly impossible to catch her with something that she hasn't already planned for. Her secondary function is Te which allows a person to dictate which decisions are going to overall assist them in achieving their overall goal. Ni produces evaluations and Te encourages diagnoses which are never-ending cycles for INTJs. Having this process often helps them focus on what they really want and so their self-confidence in their positive diagnosis and analysis leads them to do whatever it takes to make it happen INCLUDING taking the appearance of being fueled by external forces which is far from the truth. Everything is just a piece of the master plan to INTJs.
So yeah... She's definitely introverted. That was one of the easiest to categorize for me. Hope this helps you.
Anyways, as for how I made it, this picture was made out of 17 different parts: The background and all 16 characters. Each tile is it's own picture that I meticulously put together, typed up, and made looking decently, then I put them all side by side to make the chart you see here. This was actually the first chart I had ever done, so it's not nearly as clean as it could have been (See my Strike Witches chart for comparison) but it turned out alright.
I hope this helps you and lemme know when you get that done! Or if you need any help with personality analysis, I could help you out there too.
I'm so happy
It's also just nice to see an ENTJ who's not a villain
Sokka was among the easiest to sort. He's awesome!
