Peaky Blinders is one of the most popular period crime dramas ever made, and it's largely because it's bursting with characters that are invigorating, mysterious, and unpredictable. Of course, most of them are still totally likable, and they are all thrilling to watch on the small screen.

There are nine Enneagram personality types, and personality traits like loyalty, charisma, ambition, or independence will determine what type someone falls into. It's time to dive deep into the personalities of the Peaky Blinders and which enneagram type they'd fall into.

Arthur Shelby: The Challenger

This enneagram type is known as the powerful one. They have dominating personalities, and they are bursting with confidence and strength. They aren't afraid of conflict, and they act quickly and with purpose.

They are also extremely protective, as everyone has seen Arthur be. This type doesn't like being controlled, and they are usually pretty aggressive and assertive. Arthur is one of the most dangerous characters in the series, and it's because of his temper. The 'challenger' is intimidating and bold just like he is.

Polly Gray: The Reformer

The 'reformer' is rational. They have strong principles and pride themselves on seeming perfect and having great self-discipline. They act mostly out of their own sense of morality and are willing to make waves when it matters.

Like Polly, this type of person is also guilty of being a bit critical. However, she's also super organized, determined, and wise. This enneagram type is generally a good person who is bursting with integrity, just like Polly Gray.

Lizzie Stark: The Loyalist

Lizzie Stark is sometimes a bit reserved, but she is also extremely reliable and perceptive. The 'loyalist' is the most devoted and committed type, and they are hard-working and trustworthy people. Lizzie takes pride in this aspect of herself.

However, they can also get defensive and suspicious, and they aren't going to let people control them. Lizzie is self-reliant, too, and knows that she can support others only if she is being treated well and is supported herself.

Finn Shelby: The Enthusiast

The youngest of the Shelby brothers is certainly far from the most intelligent, but rather, he is bold, adventurous, and spontaneous. He perfectly fits into the 'enthusiast' type, because he seeks excitement and is generally undisciplined.

He's often gotten himself in hot water, and it's mostly because he's a bit impulsive and egotistic. He wants power and fun, and he really just looks for satisfaction in all places. Finn is an 'enthusiast' through and through.

Michael Gray: The Achiever

Michael Gray enters into the criminal underworld when he meets the Shelbys, but he couldn't be more thrilled by it. The 'achiever' is all about success. They have an impressive drive and are extremely pragmatic and ambitious.

Like Michael, this enneagram type is one of the more intelligent and competent of the bunch. They are all about work and payoff, and they are willing to get competitive. Michael can be pretty terrifying, and that's because he takes this competitive spirit to the extreme.

Alfie Solomons: The Investigator

Alfie is undoubtedly one of the biggest villains of the series, but this confidant of Thomas Shelby is also a surprising fan-favorite. The 'investigator' is secretive, independent, and inventive. Like Alfie, this type is determined and likes to bring their ideas to life.

However, this enneagram type is also extremely eccentric and is known to be pessimistic or withdrawn. These traits all make Alfie the terrifying and memorable character he is. The 'investigator' prides themselves on being capable and solution-oriented.

Ada Shelby: The Peacemaker

Ada Shelby definitely sticks out among the rest. She has a kind heart, and she is trusting and supportive. Like a 'peacemaker', Ada doesn't like violence or hate. She simply wants peace, and that's why she distanced herself from the family.

This type of person is the reliable and stable one, and every fan knows Ada Shelby is the glue and the anchor of the Shelby family. This enneagram type is accepting - and all they want is truly to be stable and have peace of mind.

Grace Burgess: The Reformer

Polly and Grace may have crossed each other, but they're actually much more similar than they probably realized. Grace is also extremely dedicated to her moral compass, and she advocates for the best, most righteous decision that will benefit the most people.

She is also organized, perceptive, and has integrity. Like a true 'reformer', Grace is a perfectionist in every sense of the word, and she strives to live a perfect life that is both successful and virtuous.

John Shelby: The Challenger

John and Arthur have a lot of similar characteristics, so it makes sense that John would also be a 'challenger'. He is confident and strong-willed, and isn't afraid to speak his mind or make his own decisions, regardless of how difficult it is.

He has the strength and assertiveness of this type, and also all the negative sides, which includes being arrogant and reckless. John's boldness and his egocentric behavior are certainly big factors leading to his shocking demise.

Thomas Shelby: The Achiever

Thomas Shelby and Michael Gray are sometimes at odds, and it's because they're both trying to be the ring-leader. However, Tommy definitely has a leg-up in that department though. He succeeds because he is ambitious and intelligent, but he is also patient and extremely perceptive of how others think of him.

This character is an 'achiever' because he is self-assured, and he knows when to charm and when to deceive. He wants to be the best and find his own success, and out of all the characters, he's probably the most likely to do so.
