This article contains information that is considered canon in the "Steven Universe" universe.
All those struggles... I learned from them, and I grew! Oh my gosh! It's not just my gem powers I've forgotten! All this 'Happily Ever After' stuff has made me forget the first power I ever had! The power to change!
Steven Quartz Universe is the titular main protagonist of the show Steven Universe and its epilogue series Steven Universe Future. He is the son of Greg Universe and Rose Quartz and the only human-descended member of the Crystal Gems.
A half-human, half-Gem as a result of his parentage Steven is an extraordinarily unique being with innate powers beyond that of both humans and Gems. While only a child Steven has steadily grown from an escort of the Crystal Gems into an equal amongst their ranks thanks to his good-hearted nature and resourcefulness. Though he is a part of a monumental legacy, Steven is devoted to fulfilling his destiny as protector of humanity, just like his mother was before him.
According to Pearl and Vidalia, Steven takes after both his parents, Rose and Greg respectively. He is relatively short with a thick, stocky build. He has curly brown hair and full black irises. He wears a salmon-pink T-shirt with a gold star in the center of it. He also wears cuffed blue jeans and salmon-pink flip-flop sandals.
In Steven Universe: The Movie, he still has his jeans and sandals, but now wears a sky-blue shirt with a yellow star in the middle and a pink varsity jacket with white trims. He is also slightly taller and has a visible neck.
As of Steven Universe Future, he retains his outfit from the movie, but his shirt is now black with a yellow star in the center, resembling his father Greg's old Mr. Universe shirts.
He is a super-excitable, hammy kid.
Steven looks up to his caretakers — Garnet, Amethyst, and Pearl — and considers them family. He wants to be a great hero just like them, and he is eager to go on adventures with the trio, both to prove his worth and to have fun exploring strange lands. Despite his under-developed magical power and lack of experience, he has proven himself to have much heroic potential through his resourcefulness, optimism, and confidence.
Steven is rather naive and socially oblivious, due to his isolated upbringing by the Gems. Steven has never attended a school and, prior to "Nightmare Hospital", had never been in a hospital or had his vitals taken. While Steven is often prepared to go on adventures at a moment's notice, he has a habit of biting off more than he can chew, requiring the Gems to intervene. While Steven initially retained his childlike innocence and obliviousness to the dangers he's frequently put in, his encounter with Homeworld Gems gave him a new level of seriousness about being a Crystal Gem. This initially made Steven self-conscious about his immaturity and he resolved to outgrow it, although his misguided attempt would be a source of self-inflicted misery as he tried to break off his friendship with Connie to protect her from harm. It was only Connie's sensible nature that stopped him from going down a bad road.
Like his mother, he appears to be very charismatic; easing a raging crowd (in "Political Power"), motivating his friends and father in working out, and helping Pearl to find the strength to fight Sugilite (in "Coach Steven"). His genuine kindness, sincerity, and capacity for sympathizing let him inspire friendship, trust, and love from most of the people he meets which enables him to mend others' inner turmoil and reach others who are otherwise closed off, most noticeably in the cases of Peridot and Lapis Lazuli.
But the truth is, we rely on you. Your voice inspires us, binds us, reminds us why we promised to protect the planet. You need to be that voice. For them.
|—Garnet to Steven in "The Return"|
Steven is shown to have unique tastes in entertainment. He enjoys the Crying Breakfast Friends! show despite his dad and the Gems' inability to understand its appeal. Steven is somewhat of a romantic and loved the ending of The Spirit Morph Saga even when Connie did not agree.
Despite his naivety in some aspects, Steven still has a more grounded and practical outlook than his three caretakers, often correcting them on normal human interactions.
Despite frequently going on many fantastic adventures, Steven has retained a tendency to be easily impressed. He was quickly enamored with Mayor Dewey's play until Jamie pointed out its flaws. He was also shocked to find that his Watermelon Stevens were alive and admits that it should not have surprised him as much as it did.
While Steven is typically amicable and kindhearted by nature, Steven's enthusiasm and excitability can get out of hand and he ends up doing more harm than good. When this happens, he can be anywhere betwixt obnoxious, overbearing, and simply rude. Steven tends to let his inhibitions go out the window when doing something theatrical, as seen in "Tiger Millionaire", "Steven and the Stevens", and "Sadie's Song". His alter-ego Tiger Millionaire is the best example of Steven letting his passionate side get the better of him.
Being half-human and half-Gem, Steven is capable of using magic, though it is unknown if he possesses all the abilities of a pure Gem, such as retreating to their gemstone when taking fatal damage. As associated with his gemstone, Steven's powers are maternal in nature and the control of his gem is based on emotional clarity.Steven has shown to have some abilities of a regular Gem, but sometimes has little control of them due to not receiving enough training. He can also warp using the warp pads, and bubble objects and gemstones to be teleported to the temple with seemingly full control. He is not strictly oxygen-dependent and is vacuum resistant as shown in "Ocean Gem" and "Space Race." He has also been shown to be able to fuse when he first fused with Connie to form Stevonnie. Steven is also capable of shape-shifting, but he has not yet learned to control it. His first attempt in "Cat Fingers" was disastrous, temporarily turning him into a cat monster. While for the most part, he has a pacifistic attitude, Steven is shown to be a competent shield fighter being able to hold his own in most situations.
Due to having his mother's gemstone, he shares most of his unique abilities with her.
- Shield Proficiency: Due to possessing his mother's gemstone, Steven can summon Rose's shield. Because Steven's powers are maternal in nature, he is required to feel a strong need to protect and help others in order to call his shield out. Early on, he had little to no control over how to summon it, only calling it forth by chance or when in mortal danger. As of "Sworn to the Sword", Steven is now able to not only summon his shield with little effort but also increase its size at will. He appears to have become quite skilled in wielding it as he was able to use it in conjunction with his protective bubble and defend against Pearl's strikes. Unlike some other gems, instead of "pulling" his shield out of his gem it appears in his arms similar to Garnet's gauntlets appearing over her hands. As of "Friend Ship", he has become completely capable of summoning his shield at any moment he requires it, even being able to scale his shield large enough to defend the Crystal Gems. It should be noted, however, that overuse of his shield exhausts Steven (such as using it three times in one day).
- Projectile Shield: Steven, when in great excitement, can shoot his shield like a projectile at great speed and power. In "Friend Ship", he weaponizes it as a range attack against Peridot, hitting her in the head with enough accuracy to temporarily stun her.
- Shield Vibration: On certain occasions that Steven's shield is hit, it emits an audible vibration that disables magical constructs. In "Ocean Gem", it destabilized Lapis Lazuli's water clones when Steven's shield was hit by a ball of water. It also seems to play a brief role in "Sworn to the Sword", when a Holo-Pearl attacks his shield and it promptly deactivates (the same sound in the former episode can be heard as it does).
- Tag-team Combat: Due to the close bond they share, Steven is able to coordinate his shield techniques perfectly with Connie's swordplay, such as fighting back-to-back to defend and attack simultaneously or catapulting Connie from his shield for a powerful lunge attack.
- Fluctuating Age: As revealed in the episode "So Many Birthdays", Steven can manipulate his age through his state of mind and maturity. Steven's biological age depends solely on how old he thinks he is. As of "Steven's Birthday", he can easily change his age when not frustrated or nervous. However, like stretching, age manipulation can easily wear out the user, Steven. Consequently, overuse can have the side-effect of making Steven's biological age go on the fritz. This was shown in "Steven's Birthday" when he unintentionally transformed into his baby state when trying to impress Connie by transforming to his teenage state. Uncontrollable age changing could also potentially be caused by his emotions like most of his powers.
- Healing: Steven's saliva has the power to heal the injuries of both humans and Gems. However, it will not work on inorganic objects, as demonstrated in "Catch and Release". Steven's healing capabilities have not yet been seen to the full extent of his power, but he is shown to be capable of healing cracked gemstones as seen when he healed Lapis Lazuli in "Ocean Gem". He can also heal common human injuries and conditions, seen when he healed Connie's eyesight in "An Indirect Kiss" and Greg's broken leg in "House Guest". During the end of "House Guest," the duct tape used to fix the Geode has the same sparkle effect as his saliva, and it is speculated that the duct tape replaced his spit, although the shine could've been used as an effect. In "The Test", Pearl remarks to the other Crystal Gems that he has lost his healing ability, and that their test should hopefully increase his confidence and therefore prevent him from losing any other abilities. His loss of healing abilities could be purely psychosomatic.
- Phytokinesis: In "Watermelon Steven", Steven discovers he has the ability to grow sentient flora in the form of watermelons shaped like himself. They acted as his bodyguards, but they weren't directly under his control and the Watermelon Stevens would ignore his orders and attacked whoever they thought was threatening him, suggesting that he doesn't have full mastery over this ability thus far.
- Enhanced Strength: Steven occasionally performs feats of strength that would be impossible for a human boy his age - or even a grown man. In "Together Breakfast", Steven is able to lift and force the Together Breakfast in its mutated state into the lava pool without the other Crystal Gem's assistance. He also displays a large amount of strength in "Arcade Mania" when he rips off the top of the Meat Beat Mania arcade game to break Garnet from her trance. He displays an even further amount of strength in "The Return" when he smashes Greg's van's dashboard with a single punch, apparently hard enough to both shatter it and activate the airbags. In "Joy Ride" he's able to move Jenny away from the Escape Pod with little effort. Later on in "Friend Ship", he is shown to be strong enough to throw his shield hard enough to stun Peridot. As Gems are much stronger and durable than their appearance would indicate, Steven's superhuman strength was most likely passed down to him from his mother.
- Resistance to Anti-Gem Weaponry: Because Steven is half-human, he is resistant to anti-gem weaponry. He can pass through the yellow destabilization fields used in the Gem Warship and can grab the live end of a Gem Destabilizer with only mild discomfort.
- Bubble Shield: Steven can summon an incredibly durable bubble, as shown in "Bubble Buddies". The bubble encases him and others that he's protecting. In "Sworn to the Sword", it is shown that Steven is capable of summoning it reflexively, as he instinctively summons his bubble to protect himself and Connie due to his wariness of Holo-Pearl as a result of the events in "Steven the Sword Fighter". In "Nightmare Hospital", it is shown that Steven can expand his shield to push away enemies. The extent of the bubble's durability is unknown, although it has survived most of the following:
- The tremendous pressure of an ocean trench ("Bubble Buddies").
- Being crushed by a falling Injector ("On the Run").
- A shot from a death ray at point-blank range ("Say Uncle", non-canon).
- A spaceship crash ("Jail Break").
- Dream Communication: In the episode "Chille Tid", it is shown that Steven can communicate with gems through his dreams. Steven talked to Lapis Lazuli mentally as he was dreaming. He also saw Jasper and Malachite in the same dream at Malachite's Realm and they noticed him as well. Although, it is unknown whether this is an ability of Steven himself or due to some other outside force.
- Extrasensory Perception: In "Horror Club", Steven was able to sense the Lighthouse Gem Monster's presence as well as its emotional state.
Every moment you love being yourself, that's me, loving you.
|—Rose Quartz, in "Lion 3: Straight to Video".|
Rose is Steven's mother, although he never met her face to face since she gave up her physical form to create him, and has only heard about her. Rose's absence has left a particular void in Steven's life, as he has grown up without a motherly figure to love and is therefore unsure of what to feel about her despite wanting to, which is only made more difficult for him as everyone else does. Regardless, Steven is willing to defend Rose, like when he snapped back at Lars when he called her weird.
After Steven got to see the video Rose had left him in "Lion 3: Straight to Video", he was moved to tears when she expressed her love for him and has since grown more curious about the person Rose was. When Steven is sometimes troubled by the burden of being a Crystal Gem, he takes solace in continuing Rose's legacy by protecting the world like she wanted him to. He has also developed a habit of clutching his gem when he has something on his mind, possibly to seek support from Rose.
Steven harbors great feelings of guilt over Rose giving up her "life" in order to give birth to him. He keeps this hidden deep down inside of him and rarely expresses it. One notable exception is in "Joy Ride" where he confesses to the cool kids that he suspects that the Crystal Gems are blaming him for Rose not being around anymore - which horrifies the teenagers.
Greg Universe is Steven's father. As seen in "Laser Light Cannon" and "Cat Fingers", they share a strong father-son relationship and Greg is always emotionally supportive. Although Greg does not live with Steven, they often hang out. In "House Guest", it is shown that Steven and his father used to live together, but as Steven grew older he moved in with the Crystal Gems in order for them to teach him about "magical Gem stuff" - something which his father could not do. However, even though Greg knows that Steven is safe in the Crystal Gems' care, he is still slightly apprehensive about Steven going on missions and getting involved in "Gem stuff," which he tries to avoid if Steven brings it up, although there are some instances in which he has joined the Gems in solving problems.
Unlike the Crystal Gems, Greg doesn't seem too concerned about Rose giving up her life as Steven inheriting her "Gem identity" - other than the latter getting Steven into situations that Greg does not approve of. As such he treats him much more like his own person and Steven doesn't seem to be feeling any guilt towards Rose's "death" when he is with his father. This is probably because as a human, Greg is much more familiar and comfortable with the idea of offspring as well as death; concepts which are strange and unfamiliar to the asexual and nigh-immortal Gems.
As a result, Steven is very comfortable and relaxed whenever he is in the presence of his dad as he provides a link to the human world, away from "magical Gem stuff". He also looks to Greg for advice on life, Gem affairs, and the like.
Pearl acts more like an overprotective mother or aunt (since he is Rose's child) to Steven. Pearl harbors mixed feelings for Steven deep down; while she cares deeply for Steven she also misses his mother, Rose Quartz, very much, as they were very close to each other when she was still alive. However, she has shown a deeper affection than most for Steven, going as far as calling him her "baby" in "Say Uncle", and even admits to watching Steven once he has fallen asleep. She sees much of his mother in him, as Steven becomes a constant reminder of Rose, which is a bittersweet sentiment to Pearl. These feelings come to the surface in "Rose's Scabbard" where the revelation that Rose had apparently kept secrets from Pearl, her closest friend, and confidant, causes Pearl to break down mentally and run away from Steven and the other Crystal Gems. When Steven pursues her, she shows inward signs of resentment towards him, and Lion, which culminates in her apparent inaction when Steven misses a jump and almost falls to his doom. The two reconcile at the end of the episode, but as revealed in "Joy Ride" Steven no longer feels comfortable talking about the subject of his mom with the other Crystal Gems as he has grown to feel that they blame him for Rose not being around anymore. Even despite recent events, Steven does still feel comfortable enough to talk to Pearl about his problems in "Historical Friction". He unknowingly comforts her in stating that flaws are important in everyone and asks her to tell the real story of William Dewey. During the play, he waves to her while she is encouraging him. When he learned that pearls are made liberally as servants on Homeworld, he declares that she isn't common but she is amazing and tries to be better than she already is as said in "Back to the Barn".
Amethyst acts like an older sister to Steven, often joking around with him and joining him in his misadventures. Pearl will often scold Amethyst for being too reckless with Steven when she misleads him such as in "Cat Fingers", which Amethyst admits is probably accurate. Steven seems to acknowledge Amethyst's reckless nature, calling her out when she didn't help him in "Joking Victim" and worrying about her safety in "An Indirect Kiss". However, Steven cares greatly about her; much to Amethyst's amusement. Amethyst is becoming more motherly as time passes. An indicator of this is in "Onion Friend" when Amethyst and Vidalia joke about kids, and that Amethyst is becoming more protective of Steven, in dangerous situations (such as grabbing Steven with her whip in "Friend Ship").
Garnet acts like a lenient and kind mother, always encouraging him and setting a good example. It is shown that Steven respects her as he always listens whenever she speaks. Steven usually asks Garnet for permission before anyone else, as shown in "Monster Buddies". As shown in the aforementioned episode, Garnet is usually open to letting Steven attempt things that Pearl may not, indicating that she has more trust in him than Pearl. Despite her stoic and somewhat distant nature, the two share an occasionally close and emotional relationship. She became emotional when Steven aged rapidly in "So Many Birthdays"; in "Future Vision" she shares her "future vision" to him- which she did only because she thought he'd understand and it would bring them closer. Immediately after Sapphire and Ruby's re-fusion in "Jailbreak" Garnet acts a lot more emotional and loving towards Steven, indicative of the deep, true love that she has for him that her pre-regeneration self wouldn't, or couldn't, express.
Oh, Steven. We already love you.
|—Garnet confirming Ruby and Sapphire's feelings toward Steven|
Little is known about the relationship between Sapphire, Ruby, and Steven, other than they all care for each other, between Steven and the two halves of Garnet, but since Garnet is a Fusion Gem of the two it can be assumed that their individual feelings for Steven are similar to, if not the same as, Garnet's feelings for him. This is confirmed in "Keystone Motel", as they both apologize to Steven upon arguing in the diner, which had driven Steven to tears. Sapphire even goes so far as to cry herself, out of guilt.
Keep your hands off my Connie!
|—Steven to the Cluster Gem in "Nightmare Hospital"|
Connie is Steven's best friend. They first saw each other at a parade the year before they met. Steven was on a float for the car wash and Connie was in the crowd; Steven noticed she dropped her glow bracelet and kept it in his freezer ever since, to make it last longer. In Connie's debut episode, "Bubble Buddies," he saved her from a falling rock by using his gem to summon his bubble. He is initially very awkward and nervous to talk with her, even more so once they were trapped in the bubble because he was trying to stay calm, but was able to relax more once he gave Connie her glow bracelet. After defeating the gem monster that was attracted to the glow of Connie's bracelet, Connie appears to be amazed by Steven, saying "It was incredible!" in reaction to everything that had happened.
Their friendship has grown and presently, they appear to be close friends. In "Lion 2: The Movie", they are shown casually hanging out. In "An Indirect Kiss", Steven and Connie are shown to not care about things such as sharing the same straw. In this episode, Steven discovered his healing powers, along with fixing Connie's bad eyesight. He also genuinely cares about Connie's safety and well-being as seen in "Winter Forecast", as well as in "Full Disclosure".
In "Alone Together", the two of them accidentally fuse to form the entity Stevonnie. They are overjoyed by their ability to be fused and enjoy being Stevonnie, although it appears that they cannot control when they fuse. It seems to happen when they dance together while thinking about their feelings for each other. Connie, however, is terrified of the thought of her parents knowing about this or any of the magical things she does with Steven. It is for this reason that she lied to her parents about Steven in "Fusion Cuisine", saying that he had a traditional nuclear family. When he found out she lied, Steven felt hurt, believing that she was embarrassed by him. Fortunately, after she explained that she was simply scared of her parents not letting her see Steven again, he forgave her.
In "Sworn to the Sword", it is shown that Steven and Connie function extremely well in combat as a team, with Steven defending Connie with his shield and protective bubble while Connie attacks using her sword-fighting skills. Together, they manage to defeat multiple versions of Holo-Pearl and their ability to work well as a team was enough to surprise Pearl initially. However, Pearl was able to defeat them after she overcame her initial surprise. Pearl later admitted that they worked well together after she calmed down. In "Cry for Help", a picture of Connie can be seen in Steven's room. During "Steven's Birthday", he expresses the assumption that Connie will become president as an adult and worries that his stunted growth would make him the "First Boy" when that happens, which implies that he wants to marry her. Steven still seems to become awkward whenever Connie is close with him as shown in "Steven's Birthday" when Connie lay her head on Steven's chest.
Lion is Steven's "pet" whom he discovers in "Steven's Lion" while the Crystal Gems were retrieving the Desert Glass. He has some sort of connection with Steven and his gem as he is the only one who can go into Lion's pocket dimension and put stuff inside there aside from Rose Quartz. Lion, most of the time, does whatever he wants and often ignores or disobeys Steven. Lion is also seen to be caring towards Steven as well as being aware of Steven's needs, like when Lion kept lying on Steven's head to show Steven his pocket dimension where it contained, among other things, a video left by Rose Quartz for Steven after he said he wanted to know more about her in "Lion 3: Straight to Video".
Sadie is one of Steven's friends who, unlike her co-worker Lars, is friendly, considerate and affectionate towards Steven. In "Joking Victim", Steven helps Sadie by working at the Big Donut. Steven also helps Sadie to strengthen her relationship with Lars in "Island Adventure".
Lars appears to be annoyed by Steven. He's always making fun of him, although this may only be because he is jealous of Steven for being a Crystal Gem. Steven may be ignorant of this, however, because in "Bubble Buddies", he refers to Lars as his "BFF". However, in "Lars and the Cool Kids", he became angry with Lars and called him a jerk for insulting his mother. As of "Lars and the Cool Kids", Lars and Steven find a way to connect and Lars is seemingly on better terms with Steven. In some ways, Steven looks up to Lars, and was excited at the chance of being able to receive a high-five from him in "Future Vision". However, Steven doesn't hesitate to call out Lars on his bad behavior at times.
Onion is Steven's friend whom he talks to in the episode "Bubble Buddies". Steven addresses Onion as if they're good friends. In "Onion Trade", Steven gives his favorite action figure to him as a gift, despite the fact that Onion had originally stolen it. When they're not together, Steven expresses some confusion as to who and what Onion is, being unsure if he's even human in "Marble Madness". In "Onion Friend", Steven and Amethyst stay at Onion's house for dinner. It is there that Onion shows Steven around his room, inviting him to feed his pet snake and show Steven his collection of G.U.Y.S. and G.A.L.S.; he later gives Explorer Gal to Steven as a token of their friendship.
Peedee is Steven's friend whom he helped out in the episode "Frybo". Thanks to Steven, Peedee earned the respect of his father and doesn't have to wear the Frybo suit anymore.
Steven - is - a new friend!
|—Lapis Lazuli communicating through the mirror, "Mirror Gem"|
Steven became friends with her in "Mirror Gem" when he was given the mirror by Pearl, which turned out to not work. Then a little while later, Lapis began to talk to Steven and they became good friends, with Steven calling them "Beach Summer Fun Buddies", a nickname to which Lapis agreed. She wanted to get out of the mirror and told Steven how to do so. After she was freed, she warns Steven not to trust the Crystal Gems and walks away. In "Ocean Gem", Steven is the one who insists on speaking to her and gets angry when she refuses to do so and hurts his friends. However, he understands Lapis' desperation to go home and heals her cracked gem, which, as a result, restores her eyes and wings. She thanks Steven before departing back to her home planet. In "The Message", Steven defends her and sings a song all about her and the previous events. Steven is very concerned about her, as he was distraught by her unhappiness while she was delivering the message. Later, Lapis gives Steven a message, she addresses him specifically. In "Jail Break", Lapis fuses with Jasper, forming Malachite, as a way to save Steven. Later in "Chille Tid", while the gems are searching for Malachite, Steven's motivation is to save her from her fate of being trapped with Jasper. He soon discovers he is able to communicate with her through his dreams. While talking to her, Lapis refuses his help, saying, "Just let me do this for you!"
Steven became friends with her in "Monster Buddies" when he accidentally popped a gem bubble that the Centipeetle Mother was in. At first, she was unwary of her surroundings, being scared by the presence of the rest of the Crystal Gems. By approaching her calmly and feeding her Chaaaaps, Steven managed to calm her down, even train her. She was even willing to risk her own life to save Steven from a falling icicle. Steven believes she is not a monster and that he can help heal her in the future.
In "Catch and Release", Steven was worried about Peridot and chooses to pop her bubbled gem and release her. After he finds out she was actually short he calls her cute and teases her, leading to Peridot slapping him in some sort of playful way. After offering her the foot of her limb enhancer suit, Steven became the only person Peridot allowed into the bathroom after she locked herself in. Peridot seemed to take the gesture extremely well and is on much better terms with Steven by the end of the episode. In "When It Rains", Steven comforts Peridot and explains the process of rain and says it's harmless. After Peridot stepped out in the rain, she had claimed she had made up her mind about telling information about The Cluster, leading to Steven giving permission to go to the Kindergarten only if they hold hands the entire way, due to Steven having to watch over her. Their friendship has been getting stronger and they are trusting each other more, although in "Too Far", he was visibly upset at her calling him a "hybrid abomination".Returning from a mission to the Moonbase, Steven notices a small object in Peridot's hand. Steven asks Peridot into a truck to discuss something. Tricking Peridot, he locks her in the truck to question her about the object. Peridot reveals that is a direct communication line to the Diamonds. Shocked at her betrayal, Steven leaves her locked in the truck and tells the other Gems of what occurred, very upset at Peridot for having learned nothing. Peridot soon escapes and activates her robot to retrieve the communicator. Once she obtains it after a fight with the Crystal Gems, she opens an interface to Yellow Diamond. Peridot reports the progress of her mission to her, omitting the Crystal Gems interactions. She then pleads a case to Yellow Diamond to stop the Cluster and spare the Earth, which Yellow Diamond spitefully denies. She then orders Peridot to let the Cluster be and report for her next mission. Outraged, Peridot refuses to follow Yellow Diamond's commands and greatly insults Yellow Diamond, marking her a traitor. Steven exclaims that her actions against Homeworld have made her an official Crystal Gem.
Steven finds Sardonyx funny and articulated as in "Cry for Help". It is known that Sardonyx has taken a liking to Steven too.
Steven was really excited to meet Opal in "Giant Woman" and when he finally did, he was nervous. But then she sang a part of his song back to him, which made him delighted.
Steven met Jasper when she accompanied Peridot to Earth and was rather intimidated by her right away, and after he feels terrified by her. Jasper thinks Steven is in fact just Rose Quartz hidden in a weak constitution, possibly after a regeneration. In "Chille Tid", Steven is completely terrified of Jasper and Jasper is completely enraged at Steven. Jasper is possibly the only character in the show that Steven hasn't expressed some form of compassion with.
Listen to me Spinel. I understand. After everything you've been through, you must be in a lot of pain.
|—Steven Universe: The Movie|
Spinel sought out revenge on Steven due to him being the descendant of Pink Diamond, as stated by his broadcast, and she was jealous of the fact that he, or "Pink", now had new friends that were not herself. Hurt by Pink's abandonment, she vowed to destroy Steven's new friends and the planet that Pink had loved so much. Steven accidentally poofs her, perceiving her as a threat once she has poofed Garnet, Amethyst, and Pearl.
However, upon her regeneration, the two become mutual acquaintances, with Spinel resuming her 'Best Friend' status with Steven, as she did with Pink. The two are inseparable, with the relationship heavily skewed; coming mostly from Spinel. Upon a small disagreement where Spinel sees Steven caring more for his friends than her, she flees to Pink Diamond's Garden, where she tells Steven the story of her past. Moved, and desperate to redeem the Gem, Steven brings Spinel back to the Gems and Connie, who, after initially being wary, agree to let Steven help Spinel to deactivate the Injector.Upon deactivating it, Spinel is once again hurt by Steven's reaction; she claims he only needed her for the Injector, and did not want to be her friend. Reverting to her old behavior, Spinel attacks Steven and briefly holds Garnet hostage, before retreating to the top of the Injector. Steven ascends the injector to talk to Spinel, and they fight until it becomes apparent she has lost her motivation to destroy him and regrets her actions up until that point. Steven, now fully reunited with his powers, comforts her and claims she can start fresh with new people to be her friends. The Injector promptly explodes due to the battle, and Steven saves Spinel by entrapping her in his bubble alongside him. Steven then attempts to comfort her again, as Spinel decides she has created too much damage and must leave. The Diamonds then arrive, ready to confront Steven about where they will live, and Steven introduces Spinel to them, thus giving her the new friends he promised.
