ENTJ (Field Marshal)

ENTJs, like most NJs, enjoy making plans and carrying them out. They make really good leaders, but have trouble not being objective and accounting for emotions. They are fact-driven and good at highlighting inefficiencies. Common among visionary villains.

    Examples 
  • Erwin Smith from Attack on Titan draws his energy from external forces in spite of his tendency to keep things under wraps and speak sparingly. Even though he is a powerhouse on multiple levels, he functions more poorly as an individual than with his constructed teams and advisers to back him up. Largely based on Erwin Rommel and thus a perfect Magnificent Bastard, he is charismatic, adept at engaging others and manipulating them, but is often ruthless and driven to a fault. Despite his cold demeanor and apparent lack of humanity, Erwin is actually a warm and caring individual and is sensitive to criticisms, displaying a lack of esteem and doubt in his own abilities behind closed doors.
  • Azula from Avatar: The Last Airbender desires control above all else, and comes up with clever strategies to get it. She is cunning and manipulative, using her social skills to use people rather than befriend them.
  • One Piece
    • Quick to take charge and always the navigator with a plan, Nami takes her responsibility on the crew very seriously. She is unwavering when she has made up her mind and acts immediately on what she feels is the best course of action. It can take her a while to warm up to people, and sometimes her morals may be very black-and-white.
    • Sir Crocodile is a villainous example in the series. He shows no hesitation in taking up leadership and organizing those around him towards his long-term goals. He places military power and efficiency above all else. He shows a penchant for the finer things in life (having his base in a grand casino) and acts immediately to get the job done. Despite being calm and collected most of the time, he is easily offended and will act recklessly to dispose of anyone who dares to mock him.
  • Penn & Teller brings us Penn Jillette, a big, assertive, talkative man with critical thinking skill. He demands the same attention to critical and logical thinking from all he interacts with, and can take many disparate and seemingly random sources of information into one well-spoken position. He's very skilled at planning and executing tricks and deceptions, being a highly successful stage magician. His eloquence and lack of inhibition led him to co-host a show entirely about calling people out on their bullshit.
  • Spencer Hastings from Pretty Little Liars is often considered the unofficial leader of the group. She enjoys being in charge and is an over-achiever, constantly balancing school work, internships, after school clubs and field hockey. She is the one that usually comes up with the plans to take down "A" and rarely ever runs her decisions by her friends. She can also be very blunt when assessing problems within the group.
  • Sarge from Red vs. Blue almost always made plans to "beat those darn blues!" during the first 5 seasons, and his plans were almost exclusively createde by him only. However, he isn't very good at highlighting the errors in his plans due to his blind hatred for the blues, despite the rest of the Red team not caring about the Blues.
  • Rei Hino/Sailor Mars from the first anime of Sailor Moon has a fiery, outspoken, stubborn nature and is a perfectionistic Workaholic, also known for her strong sixth sense.
  • Dr. Ivo "Eggman" Robotnik, eternal nemesis of Sonic the Hedgehog, is one of the most cheerful and outgoing mad scientists ever devised. This digsuises the cruelly rational thoughts of a man who not only plots and schemes to manipulate everything from animals to the multicolored Wisps to literal Physical Gods for his own ends, but always has a backup plan to get away from and/or defeat Sonic. Funnily enough, his appearance is based on a caricature of real-life ENTJ Theodore Roosevelt.
  • Rachel Duncan, the Alpha Bitch of Orphan Black. She represses her emotions and is stragic, controlling and downright unhealthy. For her, it's all about getting the job done.

INTJ (Mastermind)

INTJs are clever, analytical, pragmatic and logical, and are not scared to tell someone (or themselves) when they're being stupid. They emphasize efficiency, making them simultaneously loners and excellent leaders. Their natural talent for planning and system-building often makes them the perfect villains.

    Examples 
  • Breaking Bad:
    • Walter White made a climb to power into what became a powerful drug empire, with his descent into madness demonstrating his ruthlessness, genius, ambition, and dedication.
    • Gus Fring mirrors many of the qualities of Walter, but was already controlling his empire. The conflict between two for power is a lot of what makes the latter half of the series so great.
  • Light Yagami from Death Note has a strategic mind and a clear vision of justice and is devoted to fulfilling that vision. He works alone and is not afraid to harm a few to help many.
  • Ozymandias from Watchmen, is a man who has went all the way from having nothing to becoming a crime fighter and eventually a multimillionaire. He strongly believes that anything can be achieved or solved if people use their intelligence effectively. He also understands the true problems of the world and how they can not be solved by just simply crime fighting.
  • Ross Geller from Friends does not 'get' relationships — for the longest time, he just cannot spit it out that he loves Rachel. He is passionate about science and excels in his job as a paleontologist. Despite his awkward demeanor, he is lovable.
  • Homestuck:
  • The Hunger Games is written from the point of view of Katniss Everdeen, who certainly fits the pragmatic, solitary, and logical characteristics of INTJ. Her type does cause major issues, especially in the area of emotional availability. She responds to Peeta's emotional advances with a strictly rational analysis of their situation, preferring an objective approach. Throughout her stay in the Capitol, and the ensuing Games, she strategically maneuvers herself into the best position possible, constantly planning out several moves ahead and expertly carrying out multiple attacks to gain an edge. Katniss does exhibit a large rebellious streak, and is fiercely autonomous.
  • Kuvira from The Legend of Korra is a natural leader, driven to conquer and control. She has a commitment to a progressive goal and rational way of treating people, but is not social, dealing with others only when she must.
  • Ben Wyatt from Parks and Recreation has a rational, practical way of thinking and problem-solving skills. His opinions are logical and he doesn't change them to fit others' feelings or traditions.
  • GLaDOS from Portal 2 attacks problems with a rational and analytical viewpoint. She displays a dry sense of humor although she is prone to overconfidence. She does not have a healthy grasp of her own emotions.
  • Tiana from The Princess and the Frog is hardworking and ambitious. She's committed to a far-off goal and pursues this goal despite her many struggles. She would much rather be working than socializing or playing.
  • Shadow the Hedgehog is an aloof, arrogant, snarky Anti-Hero who manages to make even Sonic himself act hostile towards him, even if he is ultimately on their side. He can be quite callously rational and judgmental, is quite individualistic, takes everything he does seriously and with a perfectionistic streak, and ultimately does not give a single fuck about what the rest of the world thinks. His entire character motivation revolves around those he is undyingly loyal to, though his outward abrasiveness does a great job of hiding this fact.
  • Hannibal Lecter from Silence of the Lambs is very intuitive, and can often see the answer clearer than someone with a better view of the problem can. He is cunning and strategic with little regard for the emotions of other people.
  • The Avatar from Fire Emblem Awakening fits this trope. Yes, s/he can support with every other character in the game, which makes the "introvert" part seem suspect, but remember that introverts actually thrive in one-on-one interactions, which comprise almost all of the support conversations. Outside of supports, the Avatar tends to defer to Chrom or Lucina when it comes to overarching goals, only taking the spotlight when the plot practically forces it on him/her. Aside from that, the Avatar is certainly clever, pragmatic, and emphasizes efficiency in terms of "dealing the most damage to the enemy without losing anyone." Grima is a good example of what s/he would be without that caveat, fulfilling the "makes a good villain" criteria.

ENTP (Inventor)

ENTPs are clever and analytical, often with quick wits and a quicker tongue. They love arguing just for the sake of arguing. They aren't fans of planning and prefer a spontaneous lifestyle. They're almost always thinking outside the box, and are easily bored.

    Examples 
  • Hanji Zoe from Attack on Titan. Hanji's excitability and unconventional attitudes often cause others to perceive them as loopy and having lost their mind, when it is quite the opposite. Hanji is extremely intelligent and ingenious, not only an excellent strategist but an inventor and scientist. Hanji values the truth and objectivity over the safety of old ideas.
  • Batman's arch-enemy, The Joker, is ENTP incarnate into a supervillain. He doesn't cause mass mayhem for the sake of a larger scheme, or even to watch people suffer. No, he just wants to ruffle everybody's feathers (especially Batman's) just 'cause. Erratic, unpredictable behavior, bombastic and comical presentation, and an apparent inability to take what he does seriously complete the package.
  • Barney Stinson from How I Met Your Mother is an ENTP. Barney's ability to analyze women and love of clever ideas to hook up with women make him a perfect fit. He loves arguing about anything including who's his best friend. He likes using different ploys to get different women and wants to make every night legen... wait for it... dary.
  • Sokka from Avatar: The Last Airbender is the joker of the group and isn't always taken seriously. However, he is good at brainstorming and coming up with new ideas. He is clever and inventive.
  • Willy Wonka from Charlie and the Chocolate Factory has the eccentricity, spontaneity, and childlike imagination firmly establishing him as an extroverted perceiver, with his inventiveness and occasional disregard for the emotions of others attesting to his intuitive thinking.
  • Sheogorath from The Elder Scrolls is the Daedric Prince of Madness, with creativity also falling within his domain. He loves interacting with mortals, sometimes even messing with them, and many of the actions he has done is because he felt like it or he was bored (which is how he got around to introducing music to the mortal plane).
  • Chandler from Friends is the sarcastic and cynical dry observer of his group of friends. He struggles with commitment and uses humor as a defense mechanism although he is eventually able to overcome these faults.
  • One Piece:
    • Usopp is smart and imaginative, coming up with grand stories at the drop of a hat and constantly improving his weapons. He can be stressed out by worrying about peopleís expectations of him and often times wishes his crew (read: Luffy) would make safer decisions.
    • Gekko Moriah is clever and full of ideas on how to improve his zombie army, yet he wonít involve himself with any of the tedious work. He appears to be a strong intuitive, able to throw out predictions for the future that miraculously come true. However, he seems caught in "the grip" of Introverted Sensing (Si), being unable to get over the loss of his old crew.
  • The Simpsons brings us Bart Simpson, a maniacal little boy with a big serving of disrespect for authority. While he does underachieve in school, uncommon among Rationals, this could be chalked up to his ADD and his ESFP father's influence. Bart has proven himself highly capable of outside-the-box thinking and strategic planning on multiple occasions throughout the show's run, and there seems to be no sign of his mischief, or his lightning-fast wit, ever slowing down.
  • Vyvyan from The Young Ones has a liveliness and punk-mad scientist personality. He strikes a fine middle between sensing and intuition by being very aware of his surroundings and senses to an animalistic degree. However, he has a leaning towards intuition as shown by his abstract and spontaneous actions, his sheer degree of imagination with his inventions, and love of arguing, conflict, and mental (and physical) stimulation.
  • The Eponymous Deadpool. Besides being extroverted as all get out, he has an amazing knack for thinking on his feet and reading between the lines. A good example of this is when he hunts weird, red, goopy goofball Carnage. And along the fact that he is certifiably insane, there have been more than a handful of moments where his perception has been a little funky.
  • Cosima Niehaus from Orphan Black gets bored of doing research quickly and wants to move onto other things. She can piece together all the information handed to her and constantly in search of new discoveries.

INTP (Architect)

INTPs are loners with a love of information and a knack for logic. This can lead to Sesquipedalian Loquaciousness, but also the opposite, as INTPs are best at describing complex ideas concisely. They are independent, creative, and curious. They are basically the 'nerds' of MBTI; that is certainly not a bad thing.

    Examples 
  • Armin Arlert from Attack on Titan is a huge bookworm and lover of knowledge, Armin ranks highly in his class for his strategic skills. His intuition is keen, and when practically applied his ability to craft a plan or come up with ideas on the fly prove extremely useful time and again. He lacks confidence and often doubts himself.
  • L, from Death Note, is widely considered as such, as a counterbalance to Light's role as an INTJ. He is reserved, absent-minded, oblivious to social norms, and compulsively analytical, all solid traits of an INTP.
  • Dipper Pines of Gravity Falls can easily qualify as an INTP. Although he is in many ways a polar opposite to his sister Mabel, he still shares her creativity (N) and curiosity (P). He is intelligent, reserved, loves to solve puzzles and his ambition towards solving the mysteries of Gravity Falls is a reoccurring theme throughout the series.
  • Dirk Strider from Homestuck has been typed as an INTP. His leadership style of "pulling the strings" is quintessential xNTP, and although his status as resident Renaissance Man and Gadgeteer Genius would suggest he's an ENTP, his predilection for independence and stoicism indicate he is an INTP, although with highly developed extroverted intuition.
  • Metroid presents its main protagonist, Samus Aran. Introversion is quite obvious; she has an unhealthily large preference for solo operation brought about by lack of human contact. Her ability to observe, record, learn from, and plan for various occurrences combines with a near-superhuman affinity for puzzle-solving and pattern recognition (and exploitation) to present the ultimate Bounty Hunter's mind.
  • Twilight Sparkle from My Little Pony: Friendship Is Magic is quite a straightforward example. Her keen intelligence and interest in science make her an intuitive thinker, with her introversion (I) and awkwardness (P) being the driving focus of the plot (at least early in the series). Also, at many points throughout the series, she demonstrates the tendency of INTPs to become intensely fixated on certain topics and problems to the point of obsession (notable examples being Lesson Zero and It's About Time).
  • The eponymous Sherlock Holmes, although he has also been typed as INTJ. His obsession with logic and tendency toward solitude firmly establish him as an INTx, but his mixture of confidence and messiness have split him between judging and perceiving. Characters based on Sherlock Holmes (such as Batman) tend to go the same route.
  • Miles "Tails" Prower from Sonic the Hedgehog 2 fits the INTP description. Though no longer his old, timid self, he's still quite reserved and perfectly willing to let someone else take the spotlight. A skilled engineer, he has designed and built many unique and innovative creations. He can devolve into technobabble and be rather untactful.
  • Jedi Master Yoda, the resident wise man of Star Wars, regards the Galaxy and the Force as enormous puzzles to be solved. He prefers to meditate with few or no others, in relative quiet, objectively peering into what The Force has to offer him. Because of this, he has an eerie ability to foresee and prepare for coming events, and read people and objects with frightening accuracy. The vast amounts of time he has spent mediating various conflicts were spent coming to rational, agreeable conditions rather than continued fighting in most cases.
  • Arin Hanson, or Egoraptor (from Game Grumps and Awesome Series) can fit into a INTP. Though, known for screaming and beatboxxing in Game Grumps, in his Sequelitis series, he looks at sequels of games in a very critical and technical way. His opinions can go against what many think (most notably, where he explains why Legend of Zelda: Ocarina of Time does not deserve as much praise as it often receives.) His critical thinking, comedy animation, and ability to give very detailed explanations of his own ideas makes him a perfect INTP.
  • Noah from Total Drama is cynical, sarcastic, analytical, and extremely smart, and prefers to think things out rather than use physical activity. He doesn't seem to like most of his teammates and hangs out with a select few characters.
