Sunset Shimmer

"True magic comes from Honesty! Loyalty! Laughter! Generosity! Kindness! I understand you, Twilight, and I want to show you the most important magic of all... the magic of friendship!"

- Sunset Shimmer to Midnight Sparkle after turning into Daydream Shimmer

Sunset Shimmer, is the former main antagonist of My Little Pony: Equestria Girls, the deuteragonist of My Little Pony: Equestria Girls: Rainbow Rocks, the main protagonist in My Little Pony: Equestria Girls: Friendship Games and the deuteragonist in My Little Pony Equestria Girls: Legend of Everfree.

She is voiced by Rebecca Shoichet (Surname pronounced Shoy-ket) who is also the singing voice of Twilight Sparkle.

Rainbow Rocks
Sunset Shimmer re-appears as the tritagonist in My Little Pony Equestria Girls: Rainbow Rocks, reformed from her villainous ways in the first film. With the exception of the Rainbooms, the rest of Canterlot High bears resentment toward her and she even resents herself for the actions she'd taken as what she refers to as a "raging she-demon". She even admits to herself and her friends that she only dated Flash Sentry to make herself more popular.

When Sunset gives the Dazzlings a tour of the school, she gets a bad vibe from them when Adagio Dazzle gets defensive about her pendant. Her suspicions are later confirmed when the Dazzlings mesmerize the students and faculty with their singing. Using a magical book with her cutie mark on the cover, Sunset sends an SOS to Twilight Sparkle in Equestria. During Twilight's role as the Rainbooms' lead singer, Sunset acts in a supportive role and keeps an eye on the competition, especially the Dazzlings during the Battle of the Bands.

When the Rainbooms lash out at each other during the final round of the Battle of the Bands, Sunset realizes the Dazzlings' true intentions and is able to stop the arguing. She even accepts partial blame due to her lack of knowledge on friendship. When the Dazzlings overpower the Rainbooms during the film's climax, Sunset Shimmer steps up and sings on the band's behalf. Her help not only gives the Rainbooms the strength needed to defeat the Dazzlings, but she also undergoes a half-pony transformation like her friends. Afterward, Sunset joins the band as a singer and guitarist, and she uses her old journal that she communicated with Princess Celestia through to write her friendship reports to Princess Twilight Sparkle.

During the credits, Sunset is seen having now been accepted by the rest of the school, as the Cutie Mark Crusaders walk happily with her and Bulk Biceps helps her get Angel Bunny down from where he is stuck.

When human Twilight's device starts gathering magic from the main characters and she releases it under pressure from Principal Cinch, she becomes overwhelmed and corrupted by the power.

After escaping, they work together to defeat Vignette, and play a song for the parade.

Personality
Throughout the first film, Sunset Shimmer is shown to be self-absorbed, condescending, manipulative, and dishonest. She frequently insults and belittles others and thinks little of it. According to human Fluttershy, Sunset makes life miserable for "anyone who stands in her way." As a result, most of the Canterlot High School student body is afraid of her. She is also not above making threats and blackmail in order to realize her goals.

When Sunset puts on the element of magic, she transforms into a demonic visage of herself. While in this form, she becomes more ruthless, going so far as attempting to dispose of Twilight. After she is defeated, Sunset Shimmer becomes immediately repentant and apologizes for her actions, appearing to renounce her prior dishonest and unkind ways.

In the second film, Sunset Shimmer has completely discarded her old self and starts believing in friendship, being kind toward others and befriending former enemies. She is also deeply repentant for her actions in the first film, referring to her transformed self as a "raging she-demon". However, she suffers from a lack of confidence, keeping silent in situations she feels it isn't her place to speak up and falling prey to the Dazzlings' taunting. During the final battle, she finally overcomes her insecurities and joins the Rainbooms in defeating the Dazzlings, gaining a half-pony form in the process. By the end of Rainbow Rocks, Sunset starts writing friendship reports to Princess Twilight using the book she once used to communicate with Princess Celestia.

By the third film, while Sunset has managed to fully integrate herself into the group and take mentions of what she did in the past with good humor, she also harbors a fear of losing her school's newly gained trust, and she becomes deeply depressed when she believes she has let them down, despite their assurances. She also becomes increasingly irritated and stressed by her struggles to understand how magic works in the human world, briefly snapping at her friends at one point. When the human Twilight Sparkle endangers her friends, Sunset's anger explodes as she berates Twilight for meddling with forces she doesn't understand, taking her own frustrations and self-doubt out on her. However, she immediately regrets her harsh words and reaches out to Twilight in friendship by the end of the film.

In the My Little Pony: Equestria Girls Holiday Special comic, Sunset Shimmer displays a forgiving and compassionate side when she forgives the Cutie Mark Crusaders for framing her as the rumormonger "Anon-a-Miss".

In Sunset Shimmer's Time to Shine, Sunset displays a considerable level of intelligence, being ahead of her friends and classmates in school and smart enough to develop various computer applications. Her affinity for science and research is also seen in The Science of Magic, where she explains she prefers a hands-on approach to studying magic over "studying ancient books".

In The Art of Friendship, Sunset has a fondness for sunflowers that she expresses through her painting in art class. Her artistic side is further shown in Display of Affection and Super Squad Goals.

A Fine Line shows that she likes to play video games, and she is excited to get the new game Tirek's Revenge.

Sunset is shown to be serious, selfless, and has a no-nonsense attitude, but she is also shown to have some anger issues at times, especially when she is stressed out; she is also very competitive and hates losing.
