I'm Cozy Glow. It's very nice to meet you, but I don't know if I'll stay long. I'll probably flunk out. I'm having so much trouble with my friendship lessons.
~ Cozy Glow introducing herself to the CMC.
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 the main antagonist of the 8th season in My Little Pony: Friendship is Magic. She first appears as a supporting character and protagonist in the episode "Marks for Effort" and the first half of season 8 and appears as the main antagonist of its two-part finale "School Raze". 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 more mysterious agenda before the season finale.

She was voiced by Sunni Westbrook.


Cozy Glow first appeared in "Marks for Effort" where she was crying outside the Cutie Mark Crusaders' clubhouse. The Crusaders approached her and asked what's wrong. Cozy answers that she is having difficulty with her lessons at the School of Friendship and fears flunking out. The Crusaders, wanting to attend the School of Friendship too, decide to help Cozy with doing her homework and assignments.

The Crusaders teach Cozy how to be friendly while doing nice deeds for Sweetie Drops, Mrs. Cake, and Big Macintosh. After Cozy gets an "A" on her assignment, the Crusaders assist her further by helping her study for an upcoming friendship exam, during which she learns about the values of friendship represented by the Elements of Harmony. However, Cozy fails the test and runs away, which causes Twilight to accuse them for intentionally bad tutoring out of spite for not being allowed into the School of Friendship themselves.

After Cozy saw what she did to the Crusaders, she decides to go to the school's guidance counselor and confesses that she failed the exam on purpose so that the Crusaders would be allowed to enroll at the School of Friendship. When the truth was revealed, Cozy finally apologized to the Crusaders for what she did to them. Finally, the Crusaders were accepted at the School of Friendship as tutors. Cozy is last seen leaving with her new friends as they set out to tutor more students.

Cozy Glow makes a few background appearances in "A Matter of Principals" and one in "The Hearth's Warming Club" just as Twilight dismisses the students for the holiday break. She appears again in "Friendship University", giving Twilight the flyers that inform her about Friendship U, and later appears after Rarity questions how Flim and Flam could have gotten a hold of the School of Friendship's lesson plans. Cozy also appears waiting in line for Starlight's counseling in "Road to Friendship".

In "What Lies Beneath", Cozy stays behind to help Twilight organize the library, when she notices the Young Six having a difficult time studying for a friendship test. She manipulates them into doubting their confidence in their friendships. She offers them her study notes for help. At the end of the episode, the Young Six meet Cozy upon their journey underneath the school, where she learns about the Tree of Harmony's test on their friendship skills. As the Young Six drift off to sleep in exhaustion, Cozy ominously looks at the vent where the Tree of Harmony is hidden.

By the season finale episode "School Raze", Cozy's villainous nature is revealed as she manipulates everyone. In Part 1, she tricks the Mane Six into going to Tartarus, captures Starlight Glimmer, and, with the help of co-conspirator Lord Tirek, steals the school's artifacts to harness their magic and take over Equestria. In Part 2, after Chancellor Neighsay assumes control of the school, Cozy orchestrates a student uprising to take back her position as school headmare. She also locks the Cutie Mark Crusaders in a hall closet when they try to distract her, stating that she was already aware of their plan, and she tricks the students into believing the Young Six are trying to destroy the school. However, they soon begin to have doubts when the Young Six sacrifice themselves to save each other from Cozy's absorbing spell.

Cozy's plans are eventually foiled by the intervention of the Tree of Harmony, causing the magic she stole to return to its rightful owners. Caught between the Young Six, the Mane Six, the school students, the princesses, and the royal guards, Cozy Glow was unable to escape and is finally defeated. For her crimes and actions and being figured to be too dangerous to wonder other places, not only was she expelled from the school but also sentenced to imprisonment within Tartarus, where she tries to make friends with Tirek as she smiles evilly.


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


When she first appeared, Cozy appears to act rather sweet, cute, innocent, kindhearted and naïve. 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. However, 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 true friendship worked. Because of this, she believed that the more friends she possessed, the more "powerful" she was. To this end, she was willing to betray anypony, even those who were her friends, ask advice from the most evil of creatures and even bring ruin to her own country 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 and her friends, and even scoffed at the values of honesty, loyalty, generosity, etc., believing that she can easily make more friends without having to use any of them. Even after failing to take over Twilight's school, she continued her insane quest to gain power through "friendship", starting with her cohort and new cell-mate: Lord Tirek.

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. She also has limited knowledge of magical artifacts thanks to her pen-pal Tirek, having used them in conjunction with one another to take all of Equestria's magic and send it another realm.

Episodes and Appearances

Season 8


I'm Cozy Glow. It's very nice to meet you, but I don't know if I'll stay long. I'll probably flunk out. I'm having so much trouble with my friendship lessons.
~ Cozy Glow to the Cutie Mark Crusaders.
~ Cozy Glow
I never could have done it without your help!
~ Cozy Glow
I guess I still have a lot to learn about friendship.
~ Cozy Glow
It's just so impressive how you keep trying to understand friendship, even though it isn't in your nature.
~ Cozy Glow to the Young Six.
You get some rest. Don't give any of this another thought. Just let Cozy take care of everything.
~ Cozy Glow
Enjoying yourself in there, Starlight? I'm sorry I had to push you in. But what else could I do? You were going to ruin all my plans. (Sandbar and Cutie Mark Crusaders: [gasp]) You might get some company soon, if I can't make that annoying Neighsay back off! [inhales, exhales] All this magic needs time to drain from Equestria before my vortex sucks it to another realm. [giggles] Three days can sure seem like forever, huh? 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! [maniacal laughter]
~ Cozy Glow
Thank you, Chancellor Neighsay, for that rousing speech. I know you're a stallion who truly believes what you say. And when you say this school will be run according to EEA doctrine, I know you mean it. And when you say there won't be any more lessons from the Princess of Friendship at the School of Friendship, I guess you mean that, too. [students murmuring] (Chancellor Neighsay: That's not exactly what—) But Twilight decided to run her school outside of the EEA guidelines. And even though you tried to stop her, Princesses Celestia and Luna trusted her enough to support her. [students murmuring] (Chancellor Neighsay: Well, I-I wouldn't say that—) So, since I know you mean what you say, my question is really for the students. Are we going to give the pony who already tried to wreck Twilight's school once another chance to do it? [students dissenting] I guess things will have to stay the way Twilight wants them. Which includes leaving me in charge.
~ Cozy Glow retaking control of the school.
I can't very well have the EEA running the school if I want to run it myself. Of course, that's just the beginning. You see, if there's one thing I've learned here, it's that friendship is the most powerful thing there is. And as headmare of the School of Friendship, nopony will have more friends than me! Making me the most powerful pony in Equestria!
~ Cozy Glow to Neighsay
Do you three think you can fool me?! I know a diversion when I see it!
~ Cozy Glow after locking up the CMC
Destroy the School of Friendship?! Oh, dear! Chancellor Neighsay was wrong about a lot of things, but I guess he was right about all of you!
~ Cozy Glow turning the school against the Young Six
Wait! Where are you going?! STOOOOOP!
~ Cozy Glow's defeat
Honesty? Loyalty? Generosity? Blah-blah-blah! I can make more friends without using any of them! And if I can't do it here, I'll do it somewhere else!
~ Cozy Glow trying to escape
Hey, neighbor. Wanna be friends?
~ Cozy Glow to Tirek.
It’s always fun in Pinkie Pie’s class at the School of Friendship! Can you find all the little pictures in the big picture?
~ Cozy Glow in the signature My Little Pony magazine issue 95's What can you spot?.

  • Cozy Glow's character was inspired by the late child actress Shirley Temple, as well as the Batman villain Baby Doll.
  • It was believed 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 the Flim Flam Brothers and nearly causing an interspecies war on two seperate occasions. However, he truly cared about Equestria while Cozy Glow was willing to destroy it for her own selfish gain.
  • 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 aside from Sandbar and claims that friendship is not in their nature.
    • 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's a front.
  • Her cutie mark seems to represent chess, like how she manipulated everyone else like pieces on a board.
  • Cozy 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.
  • 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.
    • Both stole all the 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 Twilight and her friends into going to Tartarus so that they would be trapped there forever.
    • Both earned the trust of a former villain, only to betray them.
      • Tirek convinced Discord to aid him in stealing magic, but later took his as well.
      • Cozy was helpful to Starlight Glimmer until she shoved her into the magic sphere.
    • In the end, 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 the magic she stole.
  • 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, Cozy chose to refuse forgiveness and shows no empathy or remorse for her actions.
