Cozy Glow

"You know, you ponies got it all wrong. Friendship isn't "magic". Friendship is power! With Twilight and her lackeys out of my way, all of Equestria will bow to me: The future… Empress of Friendship!"

- Cozy Glow revealing her true tyrannical nature.

Cozy Glow is one of the main antagonists of My Little Pony: Friendship is Magic, appearing as the main antagonist of Season 8 and one of the main antagonists of Season 9 (alongside Lord Tirek and Queen Chrysalis). She is Twilight's former assistant and top student, former friend of the CMC and Young Six, and Tirek's protégé, as well as his cellmate. Despite her seemingly cute, happy, cheerful and friendly personality and being a good friend to everypony in the School of Friendship and Ponyville, she had a much darker agenda before the season finale.

She was voiced by Sunni Westbrook.

Appearance
Cozy is a Pegasus filly with a pink coat, auburn eyes, a cyan mane and tail that are both decorated with a white bow and white freckles on either cheek. She has a brown rook for a cutie mark.

After using the Bewitching Bell to become an alicorn, Cozy Glow gains larger wings and a long horn, along with a white chest-plate.

Personality
When she first appeared, Cozy appears to act rather sweet, cute, innocent, kindhearted and naive. She constantly displays a supposed fear of failing the class and shows immense respect for Princess Twilight and the other members of the Mane Six. After becoming Twilight's friendship assistant, she displayed an amount of confidence and compassion that allowed her to have full influence over most of the other students. However, due subtle hints in her character, it is implied that this entire behavior is actually a front for a mysterious agenda, which is confirmed in the finale of the eighth season.

As predicted, this was all a facade to hide her true nature: a selfish, manipulative, tyrannical and sociopathic brat who would do anything to get what she wants by any means necessary. Unlike the other villains in the series, who all believed friendship to be a weakness or meaningless, Cozy Glow knows full-well about the power of friendship from learning in Twilight's School of Friendship. Unfortunately, she was far too obsessed in the "power" aspect to understand or even care about how real friendship worked. Because of this, she viewed friendship as simply a tool to exploit for her own gain, and believed that the more friends she possessed, the more "powerful" she was. To this end, she was willing to betray anyone, even those who were her closest friends, ask advice from one of the most evil villains in history and even bring ruin to her own country; all just to become headmare of Twilight's school, as she believed it will allow her to gather even more friends, and thus become even more "powerful". Also, she had no real respect Twilight or her friends, never taking their lessons to heart and even scoffing at the values of honesty, loyalty, generosity, etc., believing that she can easily make more friends without having to use any of them. In addition, she showed signs of prejudice against non-ponies, having said hurtful things about the young six's races and even claiming that friendship wasn't in their nature. Even after failing to take over Twilight's school, she held on to her ambitions and continued her insane quest to gain power through "friendship", starting with her cohort and new cell-mate: Lord Tirek.

In The Beginning of the End, she constantly attempts to befriend Tirek, but her attempts only annoy him as he knows her true intention of making him her minion. When Grogar summons her and the other villains to his lair to join forces and conquer Equestria, she becomes excited by the idea, though Chrysalis and Tirek are less than thrilled. She attempts to persuade them to work together, but to no avail. She also hides behind Tirek whenever she feels threatened or nervous, showing a deal of trust for the evil centaur.

In Frenemies, Cozy Glow continues her dishonest streak by constantly insisting that Grogar left her in charge when he left the lair, though the other villains easily see through her lies. She also seems to take more pride in her status as a villain as well as her hatred for Twilight and her allies, as she sings a song about how she and the other villains work together to make the heroes suffer. It is also revealed that she becomes easily frustrated when others don't do as she demands of them, such as when Rusty Bucket refused to help her up the mountain, even when they became "friends". After teaming up with Chrysalis and Tirek, Cozy Glow along with the two then decided to eventually betray Grogar.

In The Summer Sun Setback, it is shown that Cozy Glow has no respect for her kind's traditions or holidays, and would even take great delight in disrupting them for her own gain.

Powers and Abilities
Being a small pegasus filly, Cozy Glow has no physical attributes other than being able to fly, so she must rely on her wits to accomplish her goals. She has used her charm and cuteness to manipulate the Mane Six, Starlight Glimmer and the CMC and have them unwittingly play into her hooves. She is a skilled liar and faker, having successfully convinced the CMC that she needed help with her exam, when in fact she had failed it on purpose, and faking remorse when she confesses to having done so. With these skills, Cozy effectively turned the entire student body of Twilight's school into her personal army. She is also perceptive enough to know when somepony is trying to decieve her, as she tricked the CMC and locked them in a closet when they attempted to distract her. Cozy Glow also has limited knowledge of magical artifacts thanks to her pen-pal Tirek, having used six of them in conjunction with one another to take all of Equestria's magic and send it another realm.

In The Summer Sun Setback, Cozy Glow was able to pick a lock using a paper clip to break into the Canterlot Archives along with Tirek and Chrysalis, implying that she has experience as a thief.

In The Ending of the End, using the Bewitching Bell to transform herself into an alicorn, thus gaining all the same attributes of one, such as enhanced magic.

Trivia

 * Cozy Glow is the fourth filly in the series to be an antagonist after Diamond Tiara, Silver Spoon (who were originally bullies), and Babs Seed (who thought she wanted to be a bully). Out of those fillies, however, she is far more evil and badly influenced, not to mention being far less redeemable than the three.
 * Though not explained or shown, Cozy Glow gave the Flim Flam Brothers a copy of Twilight's book.
 * Cozy Glow is the first and only major antagonist to appear in the middle of a season rather than at the beginning or end.
 * Cozy Glow is one of the few major villains in the series to be a pony.
 * Cozy Glow is the third antagonist to be a Pegasus, the first being Lightning Dust and the second being Wind Rider. However, Cozy is much more evil, more dangerous and had bigger plans than them. Furthermore, of those three, only she served as the main villain of a two-part episode.
 * Cozy Glow is one of the three major antagonists to be a season's main antagonist, appearing in more than one episode. The others are Starlight Glimmer, Lord Tirek, and Queen Chrysalis.
 * Cozy Glow's character was inspired by the late child actress Shirley Temple, as well as the Batman villain Baby Doll.
 * During her villainous reign, Cozy Glow shares similarities with Scar, Darla Dimple, and Henry Evans.
 * It was believed by many that Chancellor Neighsay would be the main antagonist of the season due to him being prejudiced against non-pony creatures, disliking Princess Twilight for teaching them about friendship, supporting Flim and Flam's false university and nearly causing an interspecies war on two separate occasions. However, he truly cared about Equestria while Cozy Glow was willing to destroy it for her own selfish gain.
 * It is very unlikely that Cozy's plan to conquer Equestria through "friendship" would've actually worked since her true nature would have eventually betrayed her. She was only truly a threat because she nearly drained Equestria of magic forever.
 * It was never explained if Cozy Glow is an orphan or if she has parents.
 * There were hints of Cozy Glow's true nature before the season finale:
 * When the Cutie Mark Crusaders offer to help her with her exam in "Marks for Effort", she asks them why they would do so if there is nothing in it for them, an early hint that she does not truly understand the concept of altruism.
 * In the same episode, when the CMC tell her what the Elements of Harmony are, she shows an evil smile for a brief moment. Also, she guesses that one of the Elements of Harmony is "control", which foreshadows her tyrannical nature.
 * Starlight Glimmer, who herself used to be a manipulative villain, admits that she finds Cozy's talent for manipulation and planning impressive.
 * In Friendship University, she ominously appears after Rarity questions how Flim and Flam got a copy of Twilight's book, suggesting she gave it to them.
 * In What Lies Beneath, she says derogatory things about the Young Six's species and claims that friendship is not in their nature, which further implies that she is not as nice as she seems.
 * At the end of the same episode, she looks ominously at the vent that leads to the Tree of Harmony.
 * Her "cute and sweet" personality is played up to an unrealistic extent, which may clue viewers in that it is a front.
 * Cozy Glow's cutie mark seems to represent chess, like how she manipulated everyone else like pieces on a board.
 * Cozy Glow has proven to be one of the most destructive villains in the series, as she not only nearly ruined Equestria; she also nearly ruined the very concept of friendship.
 * She is also one of the more unsettling ones, having demonstrated such evil at a very young age.
 * Out of all the villains in the show, Cozy Glow is youngest due to her age of being just a child, while all of the villains are full mature.
 * Cozy Glow is much like her cohort Lord Tirek as:
 * Both are hungry for power and will do whatever it takes to get it and rule over everyone else.
 * Tirek wanted to steal all magic from Equestria and rule as its god.
 * Cozy wanted to become the headmare of the School of Friendship so that she can have all the power of friendship to herself and rule as the "Empress of Friendship".
 * Both were patient and waited for some time before making their move.
 * Tirek escaped Tartarus in Season 2, but chose to lay low until the end of Season 4.
 * Cozy Glow played as an innocent filly in Twilight's school in Season 8 until the finale.
 * Both stole large amounts of magic from Equestria.
 * Tirek absorbed it from ponies one by one through his mouth to empower himself.
 * Cozy used artifacts to suck up all the magic in order to send it away into another realm.
 * Both wrongfully imprisoned others in Tartarus.
 * Tirek sent Princesses Celestia, Luna and Cadence through a portal.
 * Cozy tricked the Mane Six into going to Tartarus so that they would be trapped there forever.
 * Both earned the trust of a former villain, only to betray them afterward, which leads them to redemption.
 * Tirek convinced Discord to aid him in stealing magic but later took his magic as well.
 * Cozy acted helpful to Starlight until she pushed her into her magic-draining sphere.
 * Both were defeated by six individuals who were empowered by the Tree of Harmony.
 * The Mane Six were given super forms and overpowered Tirek.
 * The Young Six were freed from Cozy's magic sphere so that they can free all the magic she stole.
 * Both were imprisoned in Tartarus for their crimes.
 * Tirek was immediately transported there after being de-powered by the Mane Six.
 * Cozy tried to escape after her plot was foiled, but was seized by the guards and taken there.
 * Cozy Glow is also similar to her other co-conspirator Queen Chrysalis, both being evil creatures who pretend to be nice in order to achieve their goals. They both deceived their own allies for their own gain (the Changelings for Chrysalis and the School of Friendship's students for Cozy Glow), only for said allies to turn against them once their true colors are exposed right before they are defeated.
 * Cozy Glow is also similar to Starlight Glimmer, as they were both major antagonists who were just regular ponies and gained trust of almost everypony around them, but were then defeated by six individuals. But their differences are Starlight reformed after being coerced by Twilight and Cozy didn't.
 * Cozy Glow is the second student who becomes obsessed with power and betrays her own teacher. The first is Sunset Shimmer, who betrays Princess Celestia and becomes obsessed with the Element of Magic crown. However, while Sunset reformed and reconciled with Celestia when she was defeated, Cozy chose to refuse forgiveness and shows no empathy or remorse for her actions.
 * In Season 9; Cozy, along with Tirek and Chrysalis, were thought to be secondary antagonists while Grogar is the main antagonist in Season 9. However, this all changed in the finale as Grogar is revealed to be Discord and thus, Cozy and her allies took over as the main villains of the season.
 * It is unknown if Cozy Glow is either alive or deceased after being turn to stone, as Discord turned to stone, but remain alive, mostly because being immortal. Queen Chrysalis and Tirek were also immortal due to being created centuries ago and being imprisoned. The Storm King was also turned to stone and was deceased, though most likely from shattering after falling. So Cozy's fate remains a mystery.
