In a twist of irony, as Rose was actually Pink Diamond, Amethyst's 'mother' in as close of a way Gems can have, Steven in a way is her little brother. Big Sister Instinct: Amethyst is the closest to having a sisterly relationship with Steven and is quite protective of him.This is because she's a Quartz Gem, the soldier/warrior caste, and even though she's half the size she was supposed to be, she still has a Quartz's strength. The Big Guy: She's smaller than Garnet by default, but Amethyst is the one most likely to rely on brute force.Big Fun: Quite stocky and pudgy, and she's easily the most laid back and fun loving member of the Crystal Gems sans Steven.Oddly enough, this actually made her sick, and this is someone who drinks motor oil. One Season 1 episode sees her happily chowing down on a five-year old tuna burrito. She thinks it's delicious and asks Steven if he'd like some. She'll also pretty much eat anything, with no table manners: as a late-night snack she is seen eating macaroni and cheese powder not the macaroni but just the powder, straight from the packet, and just shoving it into her mouth with her hand. It's noted that since she's a Crystal Gem (and the one born on Earth instead of Homeworld), she doesn't actually need to eat, but she likes to do it anyway. Big Eater: To the point where she tries to chase Steven down in an attempt to get her hands on the Together Breakfast he made.Beware the Silly Ones: She's usually quite laid-back and goofy, but when she gets upset, she gets upset.Berserker Tears: Cries during her fight with Pearl in 'On the Run'.She barely makes her voice sound any different, lazily parrots some words she remembers them saying, doesn't bother to remember basic personal details (up to the names of the people she's trying to fool), and vocally tries to affirm her supposed identity ('It's cool, I totally work here!'). Bad Impressionists: Amethyst's attempts to disguise herself as other people are hampered both by Morphic Resonance and her consistently terrible impersonations.She is also the youngest Earth Quartz because she emerged late. Her Shapeshifter Default Form even looked much younger right before Steven was born, despite the time since then being a very small part of her current lifespan. The Baby of the Bunch: Before Steven came around, Amethyst was the youngest Crystal Gem.

To drive the point further, the intro of the pilot showed her resting on top of a couple of big cats, and her whips tend to have multiple ends, like a cat-o-nine-tails. She has a Cat Smile, has transformed into a cat a few times, has a wrestler persona called the Purple Puma, and has an extremely independent attitude and curious nature one would expect from a cat.

Animal Motif: Not blatantly obvious, but Amethyst seems to (like Steven) have a general cat motif going on.

Perhaps this is the most defining aspect of her personality as a defective lab experiment who despises her origins.

Always Someone Better: Is revealed to feel this way about Steven in 'Steven vs.

All Drummers Are Animals: The least mature of the Crystal Gems has a drum set as her instrument of choice.

Aliens Love Human Food: Amethyst loves to eat, although she doesn't need to, and will scarf down practically anything, from moldy burritos to engine oil.

She's also somewhat of a specialized case: as a Quartz soldier she should normally be about seven feet tall, but due to her taking too long to emerge from the kindergarten her growth was stunted, so instead of growing up, she grew out.

Acrofatic: Yes, she is curvy, but she can run and jump in sync with her teammates and can move at impressive speeds, especially when doing a Rolling Attack.
