Starlight Glimmer

Starlight Glimmer is a female unicorn pony and supporting character in the series. She first appears as the main antagonist of the season five premiere. She also appears as a background character in Amending Fences, What About Discord?, and possibly.

Development and design
Starlight Glimmer has a similar color scheme and name to Evening starlite and a similar color scheme to the non-siren forms of Aria Blaze. She has a pink coat, purple and grayish blue mane and tail, and a cutie mark of a purple and white star with two blue glimmering streams—sometimes concealed by a fake equal sign. Part of her real cutie mark is similar to the compass rose cutie mark of "South Pole", of Léon, usually of Prince Blueblood, sometimes of Blue Moon, and in some material of Friends Forever 13 Unnamed Stallion - Doctor. Her name follows the same pattern as Twilight Sparkle, Sunset Shimmer, and Starbeam Twinkle and includes the name of G1 Starlight.

The book The Art of Equestria reveals that Starlight's mane was originally just two shades of purple. According to director Jim Miller, Starlight "has a talent for magic as well and is a proto-Twilight character. Her colors parallel Twilight Sparkle's for that reason." Her page also reveals different mane styles that were tried out for her, including one similar to Rainbow Dash.

In mid-February 2015, Miller was asked regarding Starlight Glimmer's resemblance to Evening starlite and replied about him having no idea who Evening starlite is and them being not the same as far as he can tell. Later in the same month, he stated that Starlight Glimmer's name is not "Mayor Marx" or variations thereof, was asked in reply, "What is it? Or is that still classified?" and replied back, "You'll find out once the episode airs!"

Jim Miller teased on Twitter that Starlight might return in a future episode. Her return was confirmed at Comic-Con 2015.

According to Miller, Starlight was originally "Aurora Glimmer", but this was changed due to Disney's trademark on the name "Aurora", which is the name of the protagonist from their 1959 film Sleeping Beauty. Despite this, Hasbro previously managed to use "Aurora" as part of the name of G3 pony Aurora Mist.

In the season six premiere, Starlight begins sporting a new mane style.

Season five
Starlight Glimmer first appears in the season five premiere as the founder and leader of a mysterious village in which every resident has given up his or her cutie mark.

As the leader of this village, Starlight has the philosophy that "true friendship" comes from being equal—no more or less talented than another—and that having special talents of any kind only leads to disharmony. To this end, Starlight uses a magical artifact called the Staff of Sameness to remove her followers' cutie marks and replace them with equal signs.

When Twilight Sparkle and her friends arrive at the village, Starlight Glimmer sees this as an opportunity to spread her message of equality to all of Equestria. She leads the Mane Six to a vault of cutie marks outside the village, where she takes their cutie marks from them with the Staff of Sameness and tries to convert them over to her way of thinking. Fluttershy, the only one among Twilight's friends who appears to convert, spies on Starlight and discovers that her own equal sign cutie mark is actually makeup.

Using a bucket filled with water, Fluttershy and her friends expose Starlight's secret to her followers. It is also revealed that the Staff of Sameness's ability to remove cutie marks is Starlight's own magic and that the staff is an ordinary piece of wood. She attempts to leave with the Mane Six's cutie marks but is thwarted by her former followers. Having lost her followers' faith, Starlight retreats from the village and escapes to parts unknown.

In Amending Fences, Starlight hides her face behind a menu in the café scene. In What About Discord?, Starlight spies on the Mane Six and Discord with binoculars from a bush in the park scene.

Starlight makes her second major appearance in the season five finale. She uses a time spell created by Star Swirl the Bearded to travel back in time to the day Rainbow Dash performed her first sonic rainboom. When she prevents Rainbow from performing the rainboom, she changes Equestria's history, and she takes steps to ensure that Twilight and Spike are unable to stop her from doing so.

As Starlight and Twilight continually clash, Starlight creates numerous alternate futures in which Equestria falls into ruin. Twilight brings Starlight with her to one future in order to show her the consequences of her actions, but Starlight refuses to accept the truth. As Twilight cannot understand why Starlight acts this way, Starlight reveals that when she was a filly, her best friend Sunburst earned his cutie mark and left for Canterlot, leaving a young Starlight without a friend and with a fear of losing potential future friends. After bargaining with Twilight, Starlight decides to allow the rainboom to occur, restoring the present day.

Realizing the error of her ways, Starlight accepts whatever punishment that Twilight and her friends give her. Instead of punishing her, however, Twilight and her friends decide to teach Starlight about the magic of friendship, and Starlight feels reinvigorated with new life.

Season six
In the season six premiere, Starlight has taken up residence in the Castle of Friendship as Twilight Sparkle's pupil, and Twilight presents her with her first friendship lesson: reuniting with her old friend Sunburst. Because of her past actions, Starlight is very nervous about seeing Sunburst again. When the two finally meet again, their dialogue is mostly awkward stuttering.

After a failed reunion, Starlight is convinced that Sunburst no longer wants to be her friend. However, when she approaches him later and learns he didn't become an all-important wizard like she believed, Starlight finds that past failures is something they have in common, and the two help Twilight and her friends save the Crystal Empire from an eternal winter.

Their friendship rekindled, Starlight and Sunburst say goodbye on much friendlier terms and promise to keep in touch.

Personality
When initially introduced, Starlight Glimmer is openly friendly and welcoming, both toward the Mane Six and her followers. She is also somewhat of a disciplinarian, issuing punishment to those who do not conform to her philosophies. However, she later adopts a more callous and ill-tempered persona, desperate to keep up appearances and dismissing any concept of friendship that isn't the same as her own.

In the season five finale, Starlight harbors a bitter grudge against Twilight Sparkle, mocking and belittling her attempts to stop her from altering the past. Her contempt for cutie marks is revealed to be a result of losing her childhood friend Sunburst when he gained his, giving her a distorted conception of "equality". When Starlight finally realizes how friendship is enriched by ponies' differences, she adopts a remorseful, friendlier, and overall happier side.

Magic
Starlight Glimmer is very skilled in using magic and mentions that she has studied a spell for years. She wields an ordinary wooden staff called the Staff of Sameness while casting a spell in a ceremony known by her followers as "cutie unmarking," pretending this to be the staff's power instead of her own. She also uses telekinesis at long range, projects magical barriers, creates distracting lights, and shoots powerful magic blasts. In The Cutie Re-Mark - Part 1, Starlight demonstrates self-levitation, cloud-walking, and crystallizing spells. In The Cutie Re-Mark - Part 2, Twilight states that Starlight's magic rivals her own.

Software
Starlight Glimmer is a playable character in Gameloft's mobile game, added in the version 2.4 update on July 20, 2015. Her in-game description states, "Starlight Glimmer is a fancy pony that learns a valuable lesson about the true magic of friendship!" Starlight also appears in Hasbro's Friendship Celebration app.
