Steven is the lovable, half-human and half-Gem boy who is still figuring out to harness his power – the Rose Quartz gem he inherited from his mother. The ultimate "little brother", he's goofy, energetic and positive about everything. Steven is always the center of attention, and when he's not he'll fight to be back in the spotlight.
Acrofatic: Steven can move for an overweight ten-year-old in sandals. His dexterity doesn't suffer much either. He even lampshades this after reassembling his Friendship Breakfast after it flies through the air by catching each piece one by one back on the plate.
Ancestral Weapon: He inherited his mother's gem, though it seems his weapon isn't the same.
Body Horror: He experiences this in Cat Fingers. It's pretty cute to have kitty heads on his fingers. It's Resident Evil territory once said kitty heads grow in and out from all over his body at unthinkable places.
Defence Mechanism Superpower: His deflector shield first manifested in "Bubble Buddies" to protect Connie from a falling boulder. Unfortunately, Steven doesn't know how to turn it off, and when it finally turns off by itself, they happen to be underwater (thankfully, it wasn't too far down).
Deflector Shield: He's also capable of creating a spherical energy shield with his gem.
The Ditz: Often doesn't make the smartest decisions.
Ditzy Genius: As out there as his behavior may be, the plans he comes up with often involve inventive, outside the box thinking that his sisters can't necessarily replicate.
Flower Motifs: Inherited from his mother. His shield has a rose pattern on the front and his Deflector Shield emerges from a rose that grows over him.
Heroic BSOD: After Steven becomes dejected that his intentions of celebrating a birthday party for the Gems seem childish, he starts moping around town. He's completely unaware that he's magically physically aging up the more he sulks and dwells on the issue of maturity.
How Do I Shot Web?: He struggles to learn to use any of his Gem magic voluntarily. It tends to activate and deactivate on its own.
Jumped at the Call: He may not be ready to help save the universe, but that won't stop him from trying.
The Load: Played with. The major cause of the problems faced by the heroes in each episode (save for episodes such as "Laser Light Cannon") tends to be Steven himself, usually in a well meaning, but misguided attempt to help people. Granted, Steven does try (and succeed) to help solve said problems, but you can't deny that he's this at times.
The Millstone: He has a tendency to cause the conflicts of the show, either directly or indirectly.
Missing Mom: His mother gave up her physical form so Steven could be born.
Nice Guy: Steven is a Cheerful Child, who loves his father and the Gems deeply; he defends the latter against the daily insults of Lars. Also, despite Amethyst and Pearl saying, in their own way, that Steven's dad wouldn't be helpful, Steven didn't give a snarky comment, act like a Bratty Half-Pint, or even get angry. He wants to help the Gems protect the world. He's just a sweet and cool kid to be around with.
Nice Job Breaking It, Hero: If something goes wrong in an episode, he's often the one to blame. However, he does usually find a way to fix it.
Odd Name Out: For the record he's replacing his mother, Rose Quartz.
Plot-Relevant Age-Up/Rapid Aging: While Steven discovers that the Gems are agelessly eternal, the Gems find out that Steven's physical age is directly controlled by his state of mind. He's literally only as young as he feels.
Power Incontinence: When he does manage to activate his powers, he usually has trouble turning it off, like when he grows multiple cat heads on his body in an attempt to shapeshift into a cat.
Stout Strength: He's significantly stronger than a boy his age should be, likely due to his Gem heritage.
Tag Along Kid: Though as opposed to many examples, he's actually pretty helpful in a fight when he needs to be.
The Team Normal: Unless he can be able to control his powers, he might as well be this.
Throwing Your Shield Always Works: When Steven first successfully summons his shield, he shouts in joy and causes it to shoot out, bouncing around the room until it destroys the TV.
Tuckerization: Named after and inspired by Rebecca Sugar's brother Steven, who is also one of the show's background designers.
Voluntary Shapeshifting: Amethyst teaches him to use shapeshifting in "Cat Fingers", but Steven lacks the discipline to properly control it.
Wingding Eyes: When he's really happy, his eyes have stars in them.

Garnet is the unofficial, mysterious leader of the Crystal Gems. She's a powerful, strong and disciplined warrior. A Gem of few words, Garnet is the most aloof member of team. However when she does speak, everyone listens.
Action Girl: She's a powerful, strong and disciplined warrior
Batman Gambit: It's implied that the reason she insults Steven when the electric skull attacks in the pilot is so he can use a Comeback Tomorrow to travel back in time and bring back strategic intel—she hates Amethyst and Pearl teasing Steven under normal circumstances, and she's only slightly surprised ("You did it!") when Steven does manage to go back in time.
British Stuffiness: Garnet is noticeably less uptight than most examples, but her stiff upper lip and accent certainly fit this trope.
Gamer Chick: She gets addicted to a rhythm arcade game called "Meat Beat Mania" after Steven introduces her to it and thoroughly creams him at it after she's had some practice. Turns out something about her third eye puts her in a trance state when she's playing, though, so there are draw-backs.
Genre Savvy: See Batman Gambit for an example. Another would be her act of immediately taking Steven's cellphone to destroy it when he innocently snaps a picture of a cursed scroll.
Not So Stoic: Lost it pretty badly when it seemed like Steven was going to wither away and die of old age right before her and the others. Not as outwardly frantic or weepy as Pearl, but desperately tried shaking Steven out of it with gritted teeth, sounded very lost when she explained herself and seemed to be in a shocked daze when the other two yelled at her for it.
Super Strength: Seems to be the physically strongest of the Gems; she's able to hold back a mother centipeetle's tail and chuck Amethyst hundreds of feet away, neither of which required using her weapon.
She easily overpowers Amethyst (as Purple Puma, who one-shots almost everyone in the ring before hand) in "Tiger Millionaire".
Team Mom: She scolds the other Gems for mocking Steven in the pilot.
Third Eye: Has one covered by her shades, possibly allowing her to sense incoming threats.
Amethyst is the wild child of the Crystal Gems. She loves to instigate pranks and act ridiculous even in the face of danger, which can sometimes result in innocents like Steven getting caught in the middle of her antics.
The Hedonist: Outside of missions; Crystal Gems don't need to eat or sleep, but Amethyst likes to because she thinks they're fun.
Heel: She plays one in her "Purple Puma" wrestling persona. It would explain why she's so nonchalant about taking criticism. She's used to people hating her guts! Is a little criticism really going to phase you all that much when you've experienced an entire crowd booing you?
Freudian Excuse: Though it's implied she only enjoys being a heel because of the criticism piled on her by Garnet and Pearl. The detachment and validation of the ring is all she cares about.
Jerk with a Heart of Gold: Amethyst seems to fit this role; she steals, is quick with insults, and is the first one to laugh at misfortune yet pals around with Steven the most.
The Kirk: She tries to balance out logic and emotion. Most of the time she's the one to come up with a plan, but she also doesn't mind engaging in cheering Steven on or scolding him in a motherly fashion.
The Lancer: She acts as the second-in-command to the less talkative Garnet.
Lady of War: Given how she incorporates ballet and swordplay into her fighting style, she's easily this.
Large Ham: Shows shades of this when she and Garnet pretend to be a Heel tag team that wants to "destroy all wrestling". She even throws in a maniacal laugh for good measure.
Luminescent Blush: Pearl gives off a bluish blush from time to time (the blue coloring is likely a result of her skin color being pearly-white).
Male Gaze: You might not think it due to her looking less shapely than her teammates, but a couple of episodes seem to go out of their way to show that she has a pretty curvy derriere. Amethyst even taunts her in "Cat Fingers" by morphing into her and slapping her own rear:
Mental Picture Projector: She doesn't need a machine; she can do this on her own, as seen in "Cheeseburger Backpack" and "Serious Steven".
My Beloved Smother: Downplayed, and she's not Steven's actual mother, but she can act this way towards him. If there's even the slightest whiff of danger she wants to take Steven back home while the rest of The Gems do the dangerous stuff. While it doesn't help Steven grow as a Gem, she has a point considering how many times he's has almost gotten himself killed.
Noodle People: She's the slimmest of all the Gems and could probably hide behind a post if so inclined.
Parental Substitute: Seems to be fulfilling this role toward Steven. Pearl tends to be the most motherly towards him.
Team Mom: A bit of a worry wart, especially around Steven.

The fused form of Pearl and Amethyst.
Badass Baritone: Despite how relatively high the voices of her two reagents are, Opal has a deep, soothing voice that could put even Garnet to shame.
Energy Bow: Combines Amethyst and Pearl's weapons to form a solid bow that shoots energy arrows.
Emergency Transformation: Zigzagged. Pearl and Amethyst can fuse at anytime, but emergencies are the only times they agree on anything.
Fusion Dance: Implied, however they have to make their dance styles compatible for it to work. In terms of personality, Opal is a mix of The Composite and Two Beings In One Body. While Opal has a different personality and voice than her two halves, both halves are still individually aware and capable of disagreeing, which causes Opal to separate.
Leitmotif: "Opal" combines features of Amethyst's and Pearl's leitmotifs, utilizing Amethyst's synth drum and bass and Pearl's piano. Because of their "influences" on one another, Amethyst's swinging rhythm is turned into straight beats while Pearl's piano is more wild and dynamic.
Opposites Attract: Played straight and subverted. Pearl and Amethyst can become one person, in spite of being (or maybe because they are) complete opposites in personality. However, they have to maintain a single mindset. The moment Pearl and Amethyst disagree on a single idea, Opal suddenly comes apart.
Flower Motifs: As befitting someone named Rose. Most evident with her Laser Light Cannon, which blooms into a flower to fire, then fires a flower-shaped beam which then blooms into the shape of Rose herself. This was passed onto Steven, as the design on his shield is the same as the rose design on the bottom of the cannon.
Mysterious Past: So far we know absolutely nothing about where he came from, why he was after the desert gem, why he avoided being seen by anyone until the climax or why he chose to stay with Steven at the end.
Leitmotif: He has a little song which is played most times he's in a scene.
Nice Guy: One of the nicest. A really upbeat, laid back, and kind guy. He always helps his son when he needs him.
Non-Action Guy: Greg is not a Crystal Gem. He does get involved when Steven specifically comes to him for help, though. So even if he's not the action type he's more than willing to stick his neck out for his son.
Ship Tease: With Sadie in the pilot episode. In the series proper, while Steven and Connie watch them argue, Steven claims they're crazy about each other. In "Tiger Millionaire" she looks adoringly at him when he's cheering for, well, Tiger Millionaire.
Nice Girl: Is much nicer to Steven in comparison to Lars.
Ship Tease: With Lars in the pilot episode. In the series proper, while Steven and Connie watch them argue, Steven claims they're crazy about each other.
It's a little more obvious in "Tiger Millionaire", where it's shown that they regularly go and watch wrestling matches together. There's also a moment where Lars catches Tiger Millionaire's tie and Sadie watches him put it on with a look of absolute adoration on her face.

Frycook and owner of Beach Citywalk Fries.
Anime Hair: His blond hair looks like a stack of fries. One would think that it is part of his hat until he takes his hat off and reveals otherwise.
Cheerful Child: He seems pretty peppy and eager to help in "Bubble Buddies."
Cloud Cuckoo Lander: As his boat is sinking in "Bubble Buddies," he gives a triumphant thumbs-up sign, even as he's clearly sinking into the water. Not to mention the fact that he knows how to operate a harpoon gun and possibly owns a boat, despite being a very young kid.
I Just Want to Have Friends: While trapped at the bottom of the ocean, she laments to Steven how she doesn't have any friends and only her parents will miss her. Steven cheers her up by vowing to be her friend.
Meganekko: Her big, round glasses just make her more adorable.
Only Sane Woman: In comparison to Steven, who's quick to act but doesn't think things through. It's Connie that gets through to Onion by simply writing "harpoon gun" instead of making a diagram like Steven, and she tries to call attention to the obvious problem of freeing themselves from Steven's shield bubble using a roller coaster.
