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.
  • 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.

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.
  • 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:
  • 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.
  • 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.
  • 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 people’s 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 won’t 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.
  • 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.

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.
  • 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.
  • 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 tend to go the same route.
  • 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 should not recieve as much praise it deserves.) His critical thinking, comedy animation, and ability to give very detailed explanations of his own ideas makes him a perfect INTP.
