Cozy Glow

Cozy Glow is one of the main antagonists of the series and was sent to Tartarus along with Tirek.

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, white freckles on either cheek, and a brown rook for a cutie mark.

Personality
When she first appeared, Cozy appears to act rather sweet, cute, innocent, and naïve.

But it is implied that this is actually a front for a mysterious agenda, which is confirmed in the finale of the eighth season.

She constantly displays a supposed fear of failing the class.

In truth, however, Cozy was actually using this cute, kindhearted, and innocent act as a facade to use to hide her true nature: a selfish, manipulative, tyrannical and sociopathic filly who would do anything to get what she wants by any means necessary.

She manipulated the staff of the School of Friendship and the CMC to get them to unwittingly play into her hooves, and wanted to take over the School of Friendship, and eventually, Equestria itself with the help of Tirek.

She is also 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.

Unlike all the other villains in the series, who all believed friendship to be a weakness or meaningless, Cozy Glow knows full-well the power of friendship from learning in Twilight's School of Friendship.

Unfortunately, she was far too obsessed in the "power" aspect to understand 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 lie to, betray, hurt, steal from, and/or imprison anypony, even those who were her friends, to become headmare of Twilight's school, as she believed doing so will allow her to gather even more friends, and thus become even more "powerful".

Also, she had a low opinion of Twilight and her friends, thinking them to be "ridiculous".

She even scoffed at the values of honesty, loyalty, generosity, kindness, laughter and empathy, believing she can make more friends without any of them.

In the end, she is nothing more than a heartless little brat who thinks nothing of anypony but herself.
