I'll be elaborating further, Grey's got the same idea of what a Mary Sue is like I do.
There's quite a lot of criteria to consider if we want to do a bit of a "litmus test". The criteria in my opinion, is more or less universal, but there are certain criteria that may be exclusive to fanfiction characters and original ones. However,
just because a character may satisfy a small handful of criteria does not a Mary Sue make. I'll elaborate on this in a bit. We also have to consider the quality of the story's plot and its other characters in relation to the one under scrutiny. Some criteria can be nullified if we also look for traits that may De-Suify a character. The term arose in a certain sect of the fanfiction community, that much can be assured. Mary Sues however, contrary to popular belief, are not as obviously written these days if you believe just one or two criterion are all that it needs.
My "credentials": I used to write Mary Sues in fanfiction all the time before I got my shit together. I have read fanfiction of many types for years across Livejournal, Quizilla (defunct site that was originally intended to make fun quizzes and polls, not fanfiction), and Fanfiction. :heeheee:
General Criteria
- The character is conventionally attractive in more ways than one and is described like this by the author repetitively in either obnoxious detail or excruciating details in places that aren't appropriate times to do so. And by obnoxious, I mean OBNOXIOUS. The kind that not even the most vain person you know would describe themselves-- they go beyond even that.
- Plot revolves entirely around them such that if they do not act to it, the rest of the world is essentially unmoving in terms of action until they show up.
- "My life sucks, but a lot of conveniently good things have happened to me that would not happen to anyone else in my circumstance. My life still sucks mega dick and I'm going to whine about it a whole lot."
- Dead Parents of Legacy whom left a legacy for their child to follow in their footsteps. Can be De-Suified.
- Unusually dramatic/melodramatic background that just seems to stick out like a sore thumb against the setting and background of the other characters.
- They create melodrama everywhere they go, and never apologize for it because nobody will get angry about it (or won't stay angry for long). Can also have sociopathic tendencies but the other characters will not perceive them as such.
- Inexplicably obtain broken powers that the author doesn't bother to set sensible limits for, or applies limits when they realize the plot isn't going to progress if they don't have the power mysteriously stop working at that very second.
- Everyone, even people meant to act antagonistically against the character, likes them OR likes something about them. Even the ones that hate their guts for some reason or another. Ex. "I really hate you, but I admire your [some trait that gets wanked repeatedly]".
- Authority figures do not realistically punish any wrongdoings the character does, because it's justified by any applicable logic.
- They seemingly are presented as if they are flawed, but their actions and personality and abilities contradict this completely. They may be over-skilled, which turns into plots or Deus Ex Machinas which essentially quickly resolve conflicts in the story. This is usually done so side characters may essentially shower the Sue with praise.
- They are an over-idealized projection of the truth; a self-insert of the author, if you will. However, self-inserts in particular are a tricky thing since they may be de-Suifiable. A self-insert, or persona, may be a Mary Sue if the author is writing something that is intended to be taken seriously, but the complexities are merely a farce. Sue Inserts are a hybrid; they serve as wish-fulfillment and self-congratulatory fodder for the writer at the same time if they are written with no blatant flaws, or these flaws get fixed fairly easily. More on Self-inserts and my admitted on-the-fencedness about them below.
- Their skill may outshine everyone else's or have a minor flaw that can be filled in by a supporting character who goes back to the bench when they fulfilled their purpose to the main character. The supporting cast essentially exists solely to either convenience the main character or temporarily create drama or friction with the MC. They are not given any chance for the reader to care about their fates in the story or their relevance. They lose their dynamic potential in favor of "developing" the Sue. (This development usually doesn't happen with a Sue; you are instead given an illusion that they've developed).
- The character has a strange trait or hereditary disorder that does not exist. An example of this is the Violet pigment eye disorder; it was long debunked as a myth created by a fanfic author for their Sue as an excuse for the unnatural eye color. Is not a de-Suifiable trait if in a world where "unnatural" hair and eye color don't exist.
- The plot is resolved in a less-than-satisfactory way because the Sue is just that good at solving problems! The plot may not even be a quality form of plot because the author is more preoccupied with making the MC way past cool rather than telling a compelling story and developing the world within it.
- A completely blank slate-- arguably an anti-Sue-- that the reader can project themselves onto and fall under the illusion that the character is complex and layered with depth.
- Essentially a God in a world of other mini gods-- "I can blow up entire universes with the snap of my fingers, cause I said so."
- Oversimplified mental illnesses or trauma used by the Sue to force someone to love them and "fix them"-- a subgenre of Manic Pixie Dream Girl.
Fanfiction-specific Criteria (can be added to list of general criteria when evaluating a fanfic sue)
- In a relationship with a canon character that absolutely would not get along with them, let alone pursue romance. Bonus Sue points if the canon one happens to be in a relationship in-universe, but will defile that relationship for the Sue. Not applicable if it is unrequited love.
- Sue essentially retells the original story to include them.
- Child of 2 powerful canon characters and happens to possess the powers of their parents. Essentially a carbon copy of the parent characters rather than actually being their own person. Also possesses their personality traits, as if they were inherently genetic.
- Born with unnatural hair and eye color in the universe that does not have such things.
- "I'm just like a canon character, but a cooler version"
- Manages to fix things in the plot that drastically alters development of canon characters. Essentially a timeline manipulator in a figurative sense.
- Everyone likes them. EVERYONE. Even has a list of Friends, best friends, and frenemies. Their enemies are probably just enemies for a shallow thing about the Sue, and not because they are affiliated with the Hero cast.
- Possesses a power that in the universe shouldn't exist.
- "Fixes" a part of the plot the writer didn't agree with. May not be applicable if these 'parts' happen to be a commonly criticized thing by other fans and can fix the plot in a way that would improve the story. Ex. Fixing the Soul Eater ending so it may continue into a more intricate 'new' story brought in by the author.
- Villain Sue -- edgy and evil to show off how much stronger they are than the main characters. May also be brought in to induce drama between a second Sue and a canon character.
Self Inserts
I'm on the fence about them because they are generally harmless concepts that in theory, nobody would know about so long as the author didn't tell you outright. Hell, Stephen King infamously uses self-inserts, and he's one of the most lauded writers out there. So would a self-insert, regardless of how well or not the author writes them, constitute a Sue status? Not for me!
If a self-insert is realistically written and is given their own set of flaws that make them feel real, I don't think they would deserve getting slapped with the Sue sticker.
A common issue is not that they are too perfect, if the author actively is writing their character out of self-criticism; it may be more that they are too
boring to care about. Flaws that don't give any interesting facets about the character may contribute to this.
Besides, I've heard many a time that people put a part of their selves in their OCs; maybe one has their angry side, another manifests their optimistic naivety for the world, etc. It'd be hypocritical of me to condemn self-inserts as nothing but bad when it's fairly common to insert a part of yourself in some of your characters often enough. It's all how you work with them that counts
Do I consider a properly identified Mary Sue to be a bad thing? Well, I think Mary Sues are some of the most annoying and boring things to read about. But generally, it depends on the degree of Sue-ness and the circumstances; maybe they need to have some Sue traits in order for the adventure to begin (like Harry Potter).
What makes a character a non-Sue? Well, they feel
real. They have complexity to them; they act differently according to different facets of a situation. The character has more to them than a few adjectives, part of them remaining a slight enigma until the plot begins progressing in such a way to reveal more about them and how they'd react to many different things. Some bits of De-Suifying traits, in my opinion are:
- You write things to poke fun at the character's faults, and/or make it a running gag. Maybe it becomes its own source of conflict.
- The character sometimes does things impulsively without rational thinking of the consequence that impacts how other characters see them in a potentially negative light. Further De-Suifiable if the other characters will call them out on it.
- They are reckless (either sometimes or continuously), rush into fighting without thinking, and gets their shit pushed in. Bonus points if they get berated by their allies afterwards about it.
- The character has a flaw, weakness, or some form of physical disability they cannot compensate for in any way on their own. (Or at all! Sometimes there's nothing anyone can do to help).
- The character has a debilitating fear, or cognitive disorder that greatly affects how they can respond to situations in less-than-desirable outcomes.
- You character has to rely on others for help because they realize they cannot do everything by theirselves.
- They question their own morality and/or others question their morality. Maybe they'd admit to being wrong even if they didn't mean it because they didn't want their supporting cast to disapprove of them.
- They have flaws that make them insecure to their core, or they have fears/trauma that no amount of love or kisses can melt away. This trauma also has been extensively looked into so you can portray it with tact.
- the MC is a subverted trope, or portrays non-Sue traits that make them interesting for being a certain species (i.e. a vampire who has no moral issues with killing humans and thus is a manipulative sociopath that no number of pretty pixie dream human girls can civilize)
Are all main characters Sues? Again, my answer is it depends! Perhaps they have outlandish strength that nobody has managed to successfully outdo-- like Saitama from One Punch Man, but is ultimately not a Sue because he is 1) Bland looking/Bald despite being a young man, so he doesn't get any ladies... lol 2) he's a penny pinching miser and is not ashamed about it 3) Blunt in speaking to the point of insulting others 4) is an anti-Sue because nobody takes him very seriously even when he demonstrates his power through inopportune times (such as destroying Sea King after ~10 C-S class heroes attempted battle. Civilians instead held more respect for the fallen heroes because they believed they weakened Sea King, and Saitama just landed a lucky final blow).
Rey from The Farce Engorges (as Grey has said)
may fall under category of a Sue because
- She has no memory of her parents besides being alluded to as people who abandoned her on a desert planet, but the Force has resonated with her enough for her to be able to wield Luke's saber. Because the Force "works mysteriously".
- She was immediately able to start using her powers without any training.
- Was able to fly the Millennium Falcon and impressed Han Solo (you know.. the guy who can drive it) even though it apparently was the only one of its kind when she and Finn found it.
- She's done a lot in the movie without much intervention from the supporting cast; a contrast to this is Jyn from Rogue One. (Granted her team all died, but they accomplished something significant enough that without them, the plot wouldn't have progressed like it did).
- Is being foreseen as the one to counter Kylo Ren, and will presumably train under Luke Skywalker since she found him (we'll see how this goes in EP8, seeing as it is titled The Last Jedi).
- Hasn't been shown to have any crippling flaws in her personality yet, unlike her companion Finn who considered abandoning everything and backing out at some point in the movie. For now I could consider her a blank slate in the storytelling department besides "jaded cynical teenager". We'll have to wait for the next movie to come out to really be sure of her status as a possible Sue.
I don't remember enough things to De-Suify her because it was so long ago. you could argue Luke and Anakin were sues at one point in the story as well but later became De-Suified with later installments.
This got really long so I better get some fookin likes
