Stocking is a fallen angel. It’s not outright stated why she was kicked out of the pearly gates, but it’s suggested that it was due to her immense gluttony and rather poor attitude. Because those are two driving factors to her personality--Stocking loves sweet foods, and is a bitch to the umpteenth degree.

Yes, her main priority in life seems to be “acquire sweets.” Cakes, cookies, pies, ridiculously expensive foreign chocolates--Stocking wants them all, and she will get them at any cost. She is very possessive of said foods she acquires, and will get the most offended if you happen to point out to her that she's eating too much/she'll get fat. This, so much? She doesn't really care if she gets back into Heaven or not. So many delicious foods on Earth. Tying into that? She can be a massive bitch. A line in the canon song "D City Rock" actually has her say "I get high being nasty." Unlike Panty, though, who focuses more on being directly rude and blunt, Stocking is more discreet. Her insults tend to be snooty and point out actual flaws. Why does she do it? Because she thinks it's fun. She gets way too many giggles out of getting people to feel down.

Although, it does say something about the elder Anarchy sister when one takes into account Stocking is a lot nicer, and actually quite level-headed. Things that should freak Stocking out? They normally don't. She prefers to calmly analyze the situation and form a plan of action, as opposed to recklessly charging into the fire. She doesn't come up with crazy theories or weird rationalizations, and actually has moral highground over Panty. Yes, she does know that shaming people is bad and she probably should refrain from doing it--she just doesn't want to. In times of panic, though, she does drop the mean act and become a trustworthy and reliable person.

Stocking also prides herself on being high class. For an example: while she does swear like a sailor, it's less likely to be just for the sake of swearing, and more likely to drive home a point or emphasize her feelings. Her clothes and her sweets are all ridiculously fancy and expensive, and her vocabulary, despite being peppered with "fuck" and "shit" is rather eloquent. She makes it a point, repeatedly, that she actually has standards when it comes to men. While Panty will sleep with a random guy she finds, Stocking prefers to build up relationships first. She claims love is a lot more important to her than lust.

That all doesn't save her from being massively creepy at times, though. Apparently she has a hardcore bondage fetish and masochistic tendencies that she keeps hidden. Her first true love? A ghost made out of all things smelly and disgusting. Basically any thing you can name that would be considered abnormal, gross, or scary? Stocking probably likes it.
