Beatrice "Tris" Prior is the viewpoint character in Divergent and Insurgent, and shares the viewpoint character role in Allegiant with Tobias "Four" Eaton. Born in the Abnegation faction to Andrew and Natalie Prior, she describes herself as having pale blonde hair, wide gray-blue eyes, a long, thin nose and a short and skinny stature. She bears a tattoo of three ravens on her left collarbone leading down to her heart, each one representing one of her family members; she also has a Dauntless seal on her left shoulder and an Abnegation seal on her right shoulder.

In Divergent, 16-year-old Tris has to take the aptitude test to determine her future faction. Tori, her test administrator, tells her that she is "Divergent", that is, she has the aptitude to fit into multiple factions (Erudite, Abnegation and Dauntless), but is warned never to tell anyone that information, not even her family members. In the Choosing Ceremony, she transfers to Dauntless, and assumes a new moniker "Tris". She befriends fellow initiates Christina and Al, who are from Candor, and Will, an Erudite transfer. In the first initiation period, her performance in physical matches against top-ranked candidates such as Peter places her on the brink of being cut from the faction, but she then participates in a capture the flag event where she plays a major part in her team's victory. She has also stood up for the other initiates.

On visiting day, her mother Natalie tells her to ask her brother to research the Erudite's simulation serum and warns her about how she is being watched, revealing she was originally a Dauntless. During the second initiation period, where the candidates are placed in a virtual reality simulation to see how they deal with their greatest fears (for Tris, it is being attacked by crows, which is symbolic of not having power or control; drowning, symbolic of being trapped and powerless, being tied and burned to death; intimacy, symbolic of Four wanting her for her body and not being able to trust him; and killing her family members, symbolic of watching her family die and being responsible for their death), Tris shows an uncanny ability to dismiss or clear the obstacles in record time. This draws Four's attention as he invites her to enter his fear simulation and gives her tips as to how to give a Dauntless-expected response.

After passing initiation, she discovers that Erudite plan to attack Abnegation. When a mind-controlling serum does not work on her, Jeanine Matthews, the Erudite leader orders Tris executed. Tris is saved by her mother, but during their escape, she is forced to shoot Will, and her mother is killed. Reuniting with her father, Caleb and Marcus, they sneak into the Dauntless base, but her father is killed in battle. Tris confronts a mind-controlled Four but helps him break free of the mind control, and then stop Jeanine in time to release the Dauntless.

In Insurgent, Tris, Tobias, Marcus, Caleb, and Peter are fugitives hiding out in Amity sector. She overhears a conversation between the Amity leader, Johanna Reyes, and Marcus that Abnegation leaders died protecting a secret. When Erudite and Dauntless traitors arrive to capture them, they escape by jumping on a train to the factionless camp where they meet Tobias's mother. During a visit to Candor, she reveals that she had killed Will. She later surrenders herself to Erudite to save her Dauntless friends, where she finds out that her brother i…

Abnegation is one of the five factions in the world of Divergent. It is dedicated to selflessness and forgetting oneself for the sake of others. It was formed on the principle that selfishness and greed is the cause of human problems. Their chosen color is gray, as they all wear gray colored, loose fitting clothes. It is represented by gray stones at the Choosing Ceremony.
Natalie Prior (née Wright) is the mother of Beatrice "Tris" and Caleb and wife of Andrew Prior. She is described as pretty, with blonde hair, and has pale green eyes with dimples on her cheeks. She was originally from Dauntless and is also a Divergent like her daughter. She explains to Tris that she was born to a Dauntless leader and that her own mother had advised her to transfer into another faction to protect her from being killed due to her status. This story, however, is only a cover-up, as Allegiant reveals that Natalie is not actually from Chicago at all, but instead from Milwaukee, another experimental city of the Bureau of Genetic Welfare. She escaped from that city at the age of 16, after her mother killed her father, and was taken up by the Bureau, whose leader, David, fell in love with her, in the fringes. Natalie was sent to Chicago to prevent Erudite from exterminating Divergents. The Bureau exposed the entire city on memory serum so they would not remember that Natalie was not there before and registered her as a 15-year-old so she could have time to adapt in Dauntless for a year. Though she originally planned to transfer to Erudite, she fell in love with Andrew Prior and the two transferred together to Abnegation. During her time in the city, she managed to save Divergents, including Amar and George, about to be executed by Erudite by secretly moving them to the Bureau.

In Divergent, she tells Tris that she loves and supports her no matter which faction she chooses. Her husband becomes disappointed when their children choose factions other than Abnegation, but she smiles at them and supports their decision. She comes to visit Tris on Visiting Day and after finding out her being Divergent, instructs her to visit her brother and talk to him about simulation serum. She also appears in Tris's Fear Landscape. When Jeanine sentences Tris to death, she comes to her rescue. She saves her from drowning in the tank and with her attempt to reach the sector where the surviving Abnegation are hiding. She dies protecting her daughter from a fatal shot.

Following her death, Tris still recounts her experiences with her mother while making many decisions. David gives her Natalie's diary during the first visit to the Bureau and she learns about her mother's true background. At the end of Allegiant, after Tris is mortally wounded by David, she has visions of her mother reaching her arms to her for an embrace before she dies.

Ashley Judd portrayed Natalie Prior in the 2014 Divergent, 2015 The Divergent Series: Insurgent, and 2016 The Divergent Series: Allegiant.
Andrew Prior is the father of Beatrice and Caleb and husband of Natalie Prior. As revealed in Allegiant, David is a descendant of the brother of Edith Prior, one of the first settlers of the Chicago experiment, and his family was originally Abnegation, but as Andrew was born in Erudite it is apparent that they switched factions through generations. Andrew's parents were friendly with Jeanine Matthews but he chose Abnegation as his faction. He is one of the council me…

Factionless is a term, referring to those who are not part of any faction. They either were born outside of the faction system, do not agree with the faction system, or were unable to complete their initiation into their chosen faction. They are the abjective, marginalized part of the faction society. According to Evelyn Johnson-Eaton, the factionless population is twice the size of the Dauntless population.
Evelyn Johnson-Eaton is the leader of the factionless. She is Tobias’s mother. She was born in Erudite but realizes that she is not smart enough for Erudite even before her initiation test. She chooses Abnegation as her faction and marries Marcus Eaton. During their marriage Marcus abuses her and eventually she had an affair and left their son with Marcus. Marcus fakes her death but she contacts Four after his transfer into Dauntless, according to Four their meeting was not a happy one. She and Tris do not see eye to eye and Tris does not trust her because she left Four with Marcus despite knowing his abusive nature. She is described as having dark hair and eyes, distinct olive skin, strong angular features and appears middle-aged. While Four physically resembles his father, he inherits his personality from Evelyn, including being a bit paranoid and highly aware as well as preferring to be left alone.

In Insurgent, Tris, Four, and several others board the Amity train to the factionless safe zone and have an audience with Evelyn. She convinces Four to make Dauntless join with the factionless to defeat Erudite and form a new government system. After the attack on Erudite, she deceives Four and the factionless take control of all weapons and announce the government of factionless. In Allegiant, Evelyn has become the new head of the Chicago society, disbanded the faction system, and forced all former faction members to operate under her command and live equally with the factionless. Her decision prompts the former faction members to form "Allegiant", a rebel group determined to restore their old way of life. During the war between Allegiant and the factionless, Four gives his mother the option to drink the memory serum, so she may be born anew and become his mother again. Realizing what she has done, Evelyn embraces Four yet does not drink the serum, then announces her intention to end the conflict.

In the epilogue, Evelyn returns from her two years of self-exile and reunites with her son, who happily embraces her.

Naomi Watts plays Evelyn in the 2015 film The Divergent Series: Insurgent and the 2016 The Divergent Series: Allegiant. In the Insurgent film, Evelyn, instead of Tori, is the one who ultimately kills Jeanine after the latter's arrest. In the Allegiant film, she is convinced by Peter to use the memory serum gas on her enemies. But Four tells her the memory serum gas will wipe the memories of everyone involved, including him, and he won't remember her as his mother. Evelyn changes her mind and tries to stop the gas, but is shot by Peter.
