#it's unclear if catra was meant to be a self-insert but i wouldn't be surprised if it was

Catra is a Mary Sue.

i can already hear the aggressive clicking of keyboards as fans write an essay on how catra is flawed and therefore not a mary sue. but just stay with me here. here's what TV tropes has to say about this archetype:

“The prototypical Mary Sue is a female character in a fanfic who obviously serves as an idealized version of the author mainly for the purpose of Wish-Fulfillment. She's exotically beautiful, often having an unusual hair or eye color, and has a similarly cool and exotic name. She's exceptionally talented in an implausibly wide variety of areas, and may possess skills that are rare or nonexistent in the canon setting. She also lacks any realistic, or at least story-relevant, character flaws — either that or her "flaws" are obviously meant to be endearing.”

so.. let's run through the list, shall we? the exotically beautiful thing isn't really mentioned much in canon, but it's clear that catra was designed to be seductive and romantically appealing.

she certainly has her fair share of “unique” features with the heterochromia, the freckles, the fangs, the claws, and her other feline features. this isn't inherently a bad thing. it's okay to want your characters to look cool. besides, some of the other characters also have really defining features (except for adora who, despite being the protagonist, has the blandest character design ever. she doesn't even get a wardrobe change, outside of her new she-ra form. and don't even get me started on bow.)

“she's exceptionally talented in an implausibly wide variety of areas” — this definitely matches up with catra. she is supposedly the "lazy" cadet, the one who only shows up at the end of each training session and doesn't put enough effort into training. now i understand that she may still have had the potential to be a strong fighter, but you really mean to say that a teenager — who is rarely ever shown training or polishing her skills — easily beats up the evil dictator who conquered several regions and likely killed thousands of people?

i get that catra was just exploiting hordak's disability but if it was this easy to defeat hordak, wouldn't someone have done this sooner? even if he is disabled, he had to be intelligent and calculating enough to do what he did so far. but no, that's not the point here. catra didn't defeat hordak because she was somehow stronger or because hordak was weak. she defeated him because the writers wanted her to. she's a girlboss and she doesn't lose to anybody, not even a centuries old tyrant who has presumably conquered half of etheria.

“she also lacks any realistic, or at least story-relevant, character flaws — either that or her "flaws" are obviously meant to be endearing.”

yeah, you get the point. she's not flawless but most of her flaws are either swept under the rug or shown to be this cute and endearing thing. oh catra is possessive over adora and attacked her for making new friends? she's just so in love with adora. catra tried to commit mass genocide because of spite? she's just heartbroken because adora dumped her. catra constantly touches people without their consent and borderline harrasses them? she's just a cute disaster lesbian.

so there it is. catra is certainly a heavily flawed character but she's a mary sue (or a "jerk sue" as some people call these type of characters) because no matter what she does or who she hurts, she is forgiven and coddled. no one mentions angella's death in s5, not even glimmer who lashed out at adora earlier for the same reason.

all of catra's actions are just vaguely put as "she made some mistakes" or "she hurt people". making mistakes and hurting people can range anywhere from accidentally calling a person stupid to murdering someone's entire family, and spop doesn't mention where catra lies on that scale. because at the end of the day, all that matters is that catra gets a happy ending at the cost of the other characters' development and happiness. basically, a mary sue is like a blackhole. they are the “best” character, according to the author, and all the characters around them have to act horribly out of character so that this character gets all the spotlight.
