Animal Motif: As opposed to his cat motif in the series, this Steven is more associated with birds.
Emotion Bomb: Like his mother, Steven can immobilize Gems by overloading them with negative emotions. He also has a lightning attack that forces people to listen to their own worst fears about themselves.
Gratuitous Foreign Language: Having spent a considerable portion of his life is Korea, Steven sometimes uses Korean words and honorifics.
Heroic BSoD: He REALLY doesn't take learning Blue Pearl seeing him as her master well.
Spoiled Brat: Steven zigzags this trope in a very strange way. In his words, "Whatever a Diamond wants, they get." However, he hasn't really been shown as actually wanting that much, relatively he loves Earth as it is, and his "end goal" when the story starts is to tour all of Earth before eventually exploring space.
Born into Slavery: All Pearls, as in canon. Blue Pearl was offered freedom by Pearl during the rebellion, but rejected it due to not knowing anything else. Even with Blue Diamond gone, she treats her son as her new master.
Literal-Minded: Blue Pearl. When asked "What's up?", she refers to the branches above her. Greg notes this is a problem with Gems, and tries to avoid figures of speech with them.
Mama Bear: Blue Pearl is extremely protective of Steven and, although she has no combat training, she is still willing to fight to protect him.
Happiness in Slavery: A complicated case with Blue Pearl. She clearly was not happy in Blue Diamond's service, just numb. She's in a much better state with Steven and Greg, but is still struggling under that weight, and it's unclear how much they truly understand the situation.
I Choose to Stay: Blue Pearl is offered the chance to leave by Pearl after Garnet captures Steven. Her response is that she is happy with Steven.
Parental Substitute: Blue Pearl acts as Steven's primary caregiver, and while she is as loyal to Steven as she was to Blue Diamond, she is treated more like a mother and friend than a servant.
Pushover Parents: Blue Pearl has a hard time saying "no" to Steven when his natural stubbornness kicks in. Justified because Blue Pearl still partially views Steven as her Diamond, and is trained to obey orders without question.
The Resenter: When pushed, she reveals deep seated resentment towards Blue Diamond. About how she was deemed 'just a Pearl' but still expected to save the world from the cluster all by herself 'and' raise Steven.
Ship Tease: With Lapis Lazuli. They always support each other when the one of them has a bad time and even Vidalia compared their closeness and their relationship to hers with Yellowtail.
Wrench Wench: She taught herself mechanics and engineering in twelve-odd years to design and build a drill to the decommission the Cluster.
Disappeared Dad: Downplayed while he isn't dead, and still sees him regularly, Greg left Steven with Blue Pearl when he turned 10 to spy on the Crystal Gems to fulfill one of Blu's last requests.
The Mole: Justified with Greg. He only comes across Rose Quartz - leader of the Crystal Gems, shatterer of Pink Diamond and Blue Diamond's enemy - by pure coincidence. He tried to keep his distance but Rose seems to be fascinated by him and quickly becomes friends. He then uses her as an unwitting informant in order to keep Steven and Blue Pearl safe, and later uses her to find Rose's fountain so that Lapis can heal her cracked gem.
And I Must Scream: Similarly in canon, she had been trapped in the mirror for thousands of years.
Because You Were Nice to Me: Lapis chooses to stay even after discovering that Steven is not her Diamond because he released her from the mirror.
Making a Splash: She can easily curbstomp the Crystal Gems with her water powers.
Ship Tease: With Blue Pearl. They always support each other whem one of them has a bad time and even Vidalia compared their closeness and relationship to hers with Yellowtail.
There's No Place Like Home: Despite sticking around Earth for Steven and Blue Pearl, she still sorely misses Homeworld and being among other Lapis Lazulis.
Casanova Wannabe: Rose Quartz has a tendency to flirt with most humans she meets, trying to kindle something with Greg and then flirting with Priyanka and Doug. Granted, it is very likely that she does not even know that she does it half the time due to having No Social Skills despite her natural charisma.
Adaptational Jerkass: Of all the Crystal Gems, she's the most vitriolic towards Greg, even before discovering he's a spy. Similarly, she has the hardest time trusting Steven.
Hot-Blooded: She's rather quick to anger, especially when she feels a fellow Pearl is being mistreated.
We Used to Be Friends: She and Blue Pearl have history, and she once offered Blue Pearl to come with her to the rebellion, thousands of years ago.
Wrench Wench: As per canon, Pearl is an expert mechanic and engineer. She and Blue Pearl are leading the construction of the drill, once Blue Pearl told the Crystal Gems about the Cluster.
The Mentor: Steven primarily trains under her to learn how to control his Past Vision
The Stoic: Unsurprisingly, she carries over this trait from canon.
Always Someone Better: Briefly felt this way about Steven when she grew jealous of his closeness to Connie.
Expository Hairstyle Change: After she got poofed in Chapter 17 "Jailbreak", she reformed copying Connie's hair and dress style, signifying how much she cares for their friendship. It also serves as a reminder of the Broken Pedistal she has for Greg after it's revealed that he was spying on them and working with Blue Diamond.
The Gadfly: She loves shapeshifting into birds to divebomb and nest in people's hair.
