With many MBTI® types to explore, Twin Peaks is famous for having a massive cast of characters, all of them somehow linked to the mysterious murder of Laura Palmer. Despite the show's eerie atmosphere and violent setup, Twin Peaks is predominantly a drama about the lives and relationships of the inhabitants of a small town, with the investigation often left in the background. Every character has their own idiosyncrasies and peculiar hobbies, offering welcoming hints of humor to the narrative and making them feel more relatable.

Since all the characters residing in Twin Peaks are so different from each other, they have distinct MBTI® types. By dissecting their personalities, some of their actions become quite predictable, and their puzzling attitudes should finally make sense. Twin Peaks is also famous for releasing a new season 26 years after the previous one, introducing new important characters as well as bringing most of these main characters back.

Laura Palmer - ESFP

Laura Palmer from Twin Peaks.

Like every ESFP, Laura Palmer likes to live life to the fullest, engaging in a series of new experiences and making the unknown a dear ally. She can be the life of the party and finds it easy to communicate with others, often succeeding at convincing her friends to join her in her suspicious adventures. Sometimes Laura gets so carried away by new opportunities that she fails to see the danger behind them.

ESFP personality types are famous for their spontaneous spirits and observant skills; they will know exactly how other people feel even if they haven't said a word. In Laura's case, she fills every slot of free time she can with activities, parties, and errands in order to escape from reality, an attempt to distract herself from Bob, the evil spirit that feeds on her soul. However, despite ESFPs excitement for new experiences, they generally never get satisfied, which explains why they are constantly on the run, looking out for more and more fun without acknowledging the consequences.

Agent Dale Cooper - IFNJ

Dale Cooper is an INFJ to the core; he gives in entirely to his absurd imagination, which often leads him to the path of the truth, as surreal as it might seem. He's aware of his talent as an investigator, but he's humble enough to not brag, putting his energy into guiding the people around him to see their own potential. Cooper could never solve Laura's murder alone, so he indirectly puts the residents of Twin Peaks on the right track to help him uncover the truth.

Some of the most hilarious Twin Peaks memes come from Dale Cooper's sense of humor. INFJs are the rarest personality types of all, which makes Cooper one of a kind: he rejects easy answers and never takes shortcuts, carrying out methodical objectives that highlight his perfectionism. While it may seem like a great trait for a detective, Cooper is often too blind to see his exhaustion, prompting his friends to force him to get a good night's sleep every once in a while.

Audrey Horne - ENTP

Audrey Horne is always looking for a reason to argue with the people around her. When there are no conflicts going on, she starts one, just for the sake of excitement. Typical of ENTPs, Audrey is often overflowing with ideas, but she never thinks about them carefully enough to execute them properly. For this reason, she constantly finds herself in a series of dangerous situations, with only her sharp wit as a weapon.

One of Twin Peaks' biggest unanswered questions is whether Cooper and Audrey should've ended up together, although it's quite possible that she only fell for him because of the thrilling challenge that came with it. Audrey's most distinctive trait is her keenness to break the rules, which doesn't change even when her character returns 26 years later.

Harry Truman - ISFJ

It should come as no surprise that Sheriff Harry Truman has the Defender personality type. Harry doesn't think twice when it comes to helping someone out. He's one of the most altruistic persons in Twin Peaks, often interrupting his work in Laura Palmer's investigation just to aid someone with another tiny problem.

While ISFJs find it hard to adapt to change, and the death of Laura drastically impacts the town, Harry does his best, with the help of Cooper, to apply his practical and analytical skills to the case. Harry is one of the most likable characters in Twin Peaks, and his big heart is crucial to uniting a sensitive, yet precise police team to find Laura's killer.

James Hurley - ISFP

James Hurley is a character who lives only in the present, not affected by the demons of his past or concerned about his uncertain future. Laura Palmer's death truly impacts him, but he knows he must move on, getting rid of Laura's heart locket and accepting Donna's love. ISFPs like James tend to be sensitive to others but are reluctant to let others help them, preferring to deal with their problems on their own and act independently. James's arc is full of ups and downs; it all depends on whether he is winning the battle against himself at the moment.

Benjamin Horne - ENTJ

Ben Horne is such a successful businessman because, like every good ENTJ, he's full of self-confidence and strategic thinking. There are many hidden details about Ben Horne that he will never reveal to anyone because of his reserved personality. He knows how to make people feel comfortable and is generally outgoing, as long as he doesn't have to deal with emotions. His dominant attitude makes him an effective boss but a terrible father and friend, intolerant to emotions that go against what he's feeling at the moment.

Shelly Johnson - ESFP

Shelly Johnson is another ESFP who adores taking risks and doesn't settle for less than she deserves. She knows that Leo, her husband, is probably the most dangerous man in Twin Peaks, yet she insists on her affair with Bobby because he takes her right out of her routine. Shelly has perfect people skills, which explains why she's the only person able to tame Leo, and her natural charm brings the attention of characters such as Agent Gordon Cole, who finds her an example of personality and beauty. Shelly tends to avoid conflict at all costs, ignoring that a life of risks usually attracts problems.

Donna Hayward - ISFJ

Donna Hayward Twin Peaks

Donna's passive and gentle personality shouldn't make her a good amateur detective at first sight, but ISFJs have a few cards up their sleeve. Donna initially adapts poorly to her best friend's shocking death, but her tender, caring way to deal with other people enables her to access information the police could never get to. She's practical and diligent in her objectives but is too sensitive to deal with the harsh reality of Twin Peaks, often taking things too personally and messing things up with James and Harold. Because she finds it difficult to make herself clear, Donna is often regarded as one of the worst characters in Twin Peaks.

Bobby Brigs - ESFP

Bobby Briggs in Twin Peaks.

Despite his impulsive behavior and erratic attitude, Bobby is much more value-driven than his personality lets out. His taste for danger comes from repressed feelings and his inadequacy in routine makes him bored. Bobby is a great athlete and smart enough to get excellent grades if he wants to, but he prefers to live unpredictably, which makes him the perfect fit for Laura and Shelly, also ESFPs. With Bobby, everything is vibrant and new. However, this is a well-known trait of poor long-term planners, which explains why he finds himself lonely and cast down in the show's revival.

Norma Jennings - ESFJ

Norma Jennings from Twin Peaks.

Similar to most ESFJs, Norma likes to pay attention to the people around her, which makes her always the first to notice something is wrong. Because of her clear moral compass and caring personality, she's the best person to come to when looking for good advice. She continues to be the town's most supportive resident, with a personal duty to show people whatever is the right thing to do. Since Norma is always ready to help anyone, she often forgets to pay attention to herself, resulting in periods of distress.

Andy Brennan - ISFP

Andy Twin Peaks

Andy is a deputy officer guided by curiosity and an eagerness to challenge himself, even though he struggles to deal with emotions in the face of danger. He's a character who changes a lot throughout the show's three seasons, evolving from an overly sensitive man to a brave officer guided by a strong sense of duty. More than once, Andy lets insecurity get in his way of sharing a brilliant, creative idea. Fortunately, the other characters are aware of his imaginative mind and are always looking for Andy's opinions on things.

Lucy Moran - ESFJ

Lucy Twin Peaks

Twin Peaks has many unresolved storylines and mysteries, and even though Lucy is always at the center of them, she doesn't let herself get carried away. Between the show's most terrifying moments, Lucy stands out as the comic relief. While she's only the receptionist at the Twin Peaks Police Department, Lucy is braver than most of the police officers. She takes her job seriously and easily connects to both newcomers and older citizens of Twin Peaks, always disposed to aid those in need. ESFJs like Lucy tend to have constructive criticism or advice to offer, although they don't take such criticism well when it's directed at them.

Pete Martell - ISFP

Pete Twin Peaks picking the phone up

Pete is one of the most underrated characters in Twin Peaks: even with all the violence and terror around him, he doesn't let himself get affected by malice. Pete is the man who started it all, discovering Laura Palmer's body and reporting it to the police. Even after the traumatizing tragedy, Pete is promptly available to answer questions and help with anything. His warmth and kindness are contagious. Pete always maintains an openly altruistic attitude despite his unpredictable mood changes.
