|“||I like to think I'm the fairest of them all.||”|
Evie’s lush dark hair falls from her forehead in a striking widow's peak, and she never leaves home without her crown.
- Evie is secretly excited to go to Auradon Prep in hopes of finding a perfect prince. She soon realizes that she is much more than a pretty face, and there’s more to life than being the fairest of them all. Armed with her mother’s Magic Mirror, she uses it to help her villainous peers carry out their parents’ evil plan.
Evie is a girl who is smart, flirty, and very kind in the long run. Unlike most of the villain kids, she is very pleasant, to the point that she was able to make the most sour villains smile with her laughter on her sixth birthday party. But don't let her charm fool you, Evie is loyal and authoritative when she wants to be. Due to her mother's insistence that being beautiful is all that matters, Evie has problems with her own vanity and is sensitive to how others view her; her biggest fear was her not ending up not being the fairest of them all. While she wishes to find a perfect prince for herself, she is not foolish to fall for a prince who looks nice but has an ugly personality, as she rejected Chad Charming when she found out how arrogant he is. She is quite intelligent, especially in chemistry. Over the course of the film, she gains more self-confidence about herself and learns there is more to life than being the fairest of them all.
In Isle of the Lost, Evie is described being the fairest of them all, with ocean blue hair, dark brown eyes and rosy lips. In the film, Evie likes to wear her hair out, whereas in Isle of the Lost she wears it as a V-braid. Just like the color of her hair, Evie wears mostly blue and black clothing. Her usual outfit is a heart-shaped ruby necklace, a dark blue cape paired with a printed leather skirt with spiderweb leggings and black combat boots. She is very well maintained from her well plucked eyebrows to the makeup her mother insists upon. She never leaves home without her mother's approval of her appearance.
Evie is castle-schooled in a castle far across the forest by her own mother, The Evil Queen, because they both were banished and cursed by Maleficent after her daughter Mal was not invited to Evie's sixth birthday party. When Evie becomes a teenager, she finally leaves of the castle to attend an evil school named Dragon Hall where she meets her first friend, Carlos. However, she becomes Mal's target for a Ultimate Scheme project and gets locked inside Cruella De Vil's fur closet, which is full of bear traps that she barely survives the ordeal. After meeting up with Carlos again, she helps Carlos on his invention about a machine that would pick up TV and radio signals from outside the dome, but it results in making a hole in the dome for a whole minute. Because of her part in the discovery, Evie is forced to join Mal on recovering Maleficent's staff which had gained back magic from Carlos' machine. Once inside Maleficent's fortress, Evie is almost cursed to go to sleep for a thousand years but Mal saves her by getting Maleficent's staff back. Afterwards, Mal makes amends with Evie and the two of them become friends.
At the beginning of the film, Evie is seen wrecking havoc with her friends in an area of the Isle of the Lost. When Maleficent gives the news that they are going to attend Auradon Prep, she is the most excited of the group, mainly because for how many princes would be there. Maleficent reveals that her plan for them is to get the fairy godmother's magic once in Auradon to release the captive villains on the Isle. Before leaving, the Evil Queen gives Evie what was left of her magic mirror that was put in a hand-mirror which will only help her to find things. Upon arrival in Auradon Prep, she is greeted by Audrey and Ben with the fact that she is a princess as well, but is slammed down by Audrey who said she was not a real princess and that her mother's royal status was stripped off when she was imprisoned on the island, crumbling Evie's hopes. After meeting a student named Doug who told them where their rooms are, Evie quickly falls in love with the room but immediately agrees with Mal that the room was gross.
That night, the girls go to Jay and Carlos' rooms to check what they were doing. While they are both having fun, Mal reminds them that it they must prove to their parents that they were evil, then she asks Evie to ask her magic mirror where can they find the wand. Evie tries to get the mirror to tell them where the wand is, only for it be vague and misunderstand her questions. However, she finds out where the wand is displayed which leads them to a museum that contained many items pertaining their parent's stories. While in the museum Mal casts a spell to put the security fall asleep to get the wand. The group attempts to steal the wand, but when Jay tries to steal it, he accidentally sets off an alarm; however, Carlos is able to trick security into thinking that it was a malfunction with the system.
Attending school, she develops a crush on Chad Charming, while in the chemistry class, she cheats by finding the answer to the question by telling the mirror while the chemistry teacher didn't notice. Chad decides to talk to her later on, during which Evie reveals how her magic mirror works, causing Chad to realize she cheated. Chad asks her if she could do his homework, which she agrees to do and also manages to get information from him about the coronation, which will have the wand in use. She passes this along to Mal, who decided to make a love potion laced cookie to win Prince Ben over. In the kitchen, the group nearly finishes the recipe, except for a missing ingredient: "a tear of true sadness". When Lonnie comes in, she asks them if they needed any help then starts talking about how her parents make her happy by baking them delicious cookies. Hearing this causes the villain kids morose, then Lonnie understands that they never received any love from their parents, causing her to cry over their misfortune and unwittingly giving Mal the tear for the recipe. The next day, Evie sees that her chemistry teacher has her magic mirror which Chad Charming gave to him. Her chemistry teacher, now knowing that Evie cheated, nearly has her expelled but is stopped by Doug who tells him it was just an accident. The chemistry teacher says that if she passes the test she will not be expelled. As a result, Evie gets away with a B+ in the test. She also begins bonding with Doug, who encourages her to not hide her intelligence.
When Mal tells Evie that Ben asked her out for a date, she helps Mal by dressing her up and giving her a nice makeover; the two bond as she does this. The next day, while the group attended class, the Fairy Godmother announces the next day is Family Day and tells them that they cannot bring their parents to Auradon but she offers them to video chat with their parents instead. While chatting with their parents, The Evil Queen is shocked to see Evie beautiful, though Evie becomes bothered by this statement. After hearing their parent's bickering, Jay switches off the video chat abruptly, though the group is left with doubts over their plan. During Family Day, Evie is talking to Queen Belle when Mal is accosted by Audrey's grandmother Leah for her mother's curse on Aurora. Mal tries to apologize for the misery her mother made but is suddenly attacked by Chad as well. In response, Evie uses a poison spray on him. Doug is about to forgive Evie but is stopped by Chad. After the scuffle, the kids decide they must get the wand and prove to their parents now that the others can't accept them.
As the day of the coronation neared, Evie serves as emotional support for her friend, even agreeing with her that keeping Ben under the spell after the villains are freed is too much.
At the day of the coronation, she made a beautiful dress for Mal. This is something that makes her mother, the Evil Queen, happy. When Jane accidentally breaks the magic barrier in the island, Maleficent is freed from the island and she comes in Auradon castle. Fairy Godmother tries to stop her but Maleficent already cast a spell to freeze everyone except Mal and her friends. Jay and Carlos try to stop her but fails. When Maleficent transforms into her fearsome dragon form. Evie uses her magic mirror to defeat her but is halted by Mal who gives her mother a stare-off challenge in which Maleficent fails and turns into a lizard, a representation of the little amount of love in her heart. With the crisis averted, Ben is proud of the group's noble act and tells them that they must trust their heart and have faith. Evie, along with Mal, Jay and Carlos choose good and then enjoys the party with her friends, singing and dancing with Doug.
