* AlternateCharacterInterpretation:
** The second episode has some of this regarding the Gems. Is their request that Greg not involve himself in magical matters out of concern for him, or do they see him as a bad role model and made the request to limit his influence on Steven? Or Greg is actually not responsible enough to be a full time parent? Or does he resent Steven for losing Rose Quartz?
** As of "Cat Fingers", it may be more because of how inherently dangerous the fledgling powers of a Gem are (learning to use his VoluntaryShapeshifting powers resulted in Steven turning into an [[BodyHorror amorphous blob of cats]] and nearly destroying himself), and Steven's dad just is not up to task to keep Steven safe from harming others, or himself. "So Many Birthdays" further supports this interpretation, as Steven almost ''died'' when he couldn't control his powers, even with the Gems there to help him.
** After "Coach Steven", Sugilite's character has been subject to a vast amount of varying interpretations. Is her personality a result of Garnet and Amethyst's mindsets at the moment of fusion, or is it a reasonable mixture of their own distinct traits? Was her lashing out at Pearl an indication that the amount of time she spent fused was causing her to go out of control, or was she justifiably hurt that Pearl left her behind?
** Lapis Lazuli of "Mirror Gem" and "Ocean Gem". Was she a threat that could've seriously hurt everyone around her? Or was she just some homesick gem that was just severely injured and didn't want to be on the planet anymore?
** Lapis brings up one for the Crystal Gems: Are they heroic protectors of Earth or heartless jailers imprisoning wayward gems regardless of their intent?
* BaseBreaker:
** Steven. Mostly for the fact that he unintentionally causes most of the episode's problems with his lack of forethought. Of course, considering that Steven is supposed to be 'the ultimate little brother' he is supposed to be annoying, so perhaps this is fridge brilliance.
** Pearl has received a somewhat mixed reactions from fans. Some fans find her quirks (She's a bit of [[SuperOCD clean]] freak, and is [[TeamMom extremely protective towards Steven]]) to be boring or annoying, others find them find them funny or endearing.
** Amethyst managed to break the base with her carefree attitude. Some fans enjoy seeing her let loose and have fun with her powers. Others find her misuse of her powers obnoxious and wish she would be more responsible.
** Lars is starting to turn into one. He often acts like a selfish JerkAss, and [[AesopAmnesia any time an episode ends with him learning humility, it completely gets forgotten by the next episode]]. However, he still has his fair share of fans and has been involved with some of the show's HeartwarmingMoments.
* BrokenBase:
** The show moved to a slightly looser and less detailed style after it was picked up, which understandably upset fans of the pilot.
** Whether or not Steven should be the main protagonist. Some think that the show would be far more interesting if it focused on the adventures of the three adult Crystal Gems rather than his ComingOfAgeStory, while others argue that the entire heart of the show is in the relationships of the characters and in particular between Steven and his mentors/guardians/family.
** As more and more episodes come out, it's become increasingly debateable among fans whether or not Greg is actually a better role model than the Gems for a variety of reasons.
* CrackPairing:
** There's Pearl x Lars.
** And [[LesYay Amethyst x Connie]]
** Amethyst x Sadie
** [[HoYay Lars x Buck Dewey]] has been growing in popularity as of late.
* CrossoverShip: Pearl x [[Manga/{{Cyborg 009}} Jet Link aka Cyborg 002]] is pretty popular, due to the fact that [[ThemePairing they have similar noses, hair color and style (although Pearl's hair is lighter and shorter), and love to dance.]]
** After the events of "Arcade Mania", fans began shipping Garnet with [[Manga/{{Dragon Ball}} Tien]] [[Anime/{{Dragon Ball Z}} Shinhan]] because they both have a ThirdEye.
* EnsembleDarkhorse: Quite a few of the side characters.
** Greg and Rose seem to be very popular.
** Many fans took quite a liking to Onion, too.
** Lars and Sadie. Frybo. Peedee. Connie.
** The biggest one thus far has been Opal.
** An explosion of fanart ensued after the introduction of Lapis Lazuli.
* FandomRivalry:
** Only a few episodes in and the fandom is locking horns with the fanbases of ''WesternAnimation/UncleGrandpa'' and ''WesternAnimation/AdventureTime''. ''Uncle Grandpa'' fans are mad that ''Steven Universe'' took its previous Monday timeslot, and ''Adventure Time'' fans see it as somewhat of a ripoff due to its superficial similarities. Ironically, ''Steven Universe'' was created by Rebecca Sugar, a former writer and storyboarder for ''Adventure Time'', and thus, many ''Steven Universe'' fans are also Adventure Time fans as well. On the other hand, a lot of ''Steven Universe'' fans see ''Uncle Grandpa'' as terrible, thus fueling the rivalry.
** Some ''Adventure Time'' fans are upset that Rebecca Sugar left to create her own show and are demanding that she return, especially the ones that feel Season 5 has been a downward slide since her departure.
* FanPreferredCouple:
** Garnet/Pearl is pretty popular.
** Amethyst/Pearl is also popular in some circles.
* GrowingTheBeard:
** The series really picks up once it starts dealing with its MythArc in "Lion 2: The Movie", seventeen episodes in.
** "Mirror Gem" and "Ocean Gem". The ending of which implies much more serious matters will occur. So much so that the creators apparently consider this as the show's "true" beginning.
* HarsherInHindsight: After the reveal that [[spoiler: all gem monsters are in fact, crystal gems trapped in a different form]], Monster Buddies just got a whole extra layer of TearJerker. Mmm, bittersweet.
* HeReallyCanAct: NickiMinaj is a surprisingly decent voice actress.
* HellIsThatNoise:
** "Maaaayor Deeeewey, Maaaayor Deeeewey, Maaaayor Deeeewey..."
** The mirror screaming in Steven's voice.
--> "Nooooo! Nooooo'''NOOOOOO'''ooooo! '''NOOOOOOOOO!'''"
* HolyShitQuotient:
** Many people were shocked to see Pearl actually get stabbed and temporarily die onscreen in "Steven the Sword Fighter".
** "Mirror Gem". Many people were really shocked at [[spoiler:the appearance of the newest Gem, Lapis Lazuli]], especially considering the previous very faint implication that [[spoiler:main cast was the last of the Gems.]]
* LauncherOfAThousandShips: As you can tell from a few entries here, Pearl.
* {{Misblamed}}: There were rumors going around that the show's design change from the pilot episode was because of ExecutiveMeddling and apparently low budgets. In reality, the change was done by the show's creator, Rebecca Sugar, and was created and finalized long before the pilot was leaked. In fact, the show's budget is much higher than the pilot's.
* LesYay: The girl's gem fusions so far have varying degrees [[GettingCrapPastTheRadar of sexuality to them]]. Predictably the fan base has exploded.
* {{Moe}}: Steven. He's not called the "ultimate little brother" for nothing.
* {{Narm}}: For some, a lot of the genuinely heartwarming moments can be ruined by the art style, which can border on GagLips at times.
* OneTruePairing: Steven/Connie, after the events of ''"Bubble Buddies"''.
* PeripheryDemographic: Though clearly a children's program, several factors (such as the creator being a well known former member of the ''WesternAnimation/AdventureTime'' crew, the flawed yet lovable characters, the [[SugarWiki/AwesomeMusic impressive soundtrack]], the [[TearJerker surprisingly]] [[SugarWiki/HeartwarmingMoments touching drama]], and jokes that would fly [[GettingCrapPastTheRadar way over most kids' understanding]]) have made it quite popular outside its target demographic.
* RuleOfSymbolism: The series often uses motifs from Hinduism, such as the multiple arms seen in the Gems' temple statue and the two fused Gems (Opal and Sugilite). [[http://stevencrewniverse.tumblr.com/post/78156709869/from-storyboard-artist-joe-johnston-some Opal was also originally planned to form a swastika with her hands when summoning her bow]]. Sugilite, with her four arms, scary-looking fangs and BloodKnight personality, strongly resembles the Hindu goddess [[http://en.wikipedia.org/wiki/Kali Kali]].
* UnintentionallySympathetic: The Pearl Hologram from 'Steven the Sword Fighter.' Essentially just a mindless automaton, the Gems seem needlessly hard on it, and Steven becomes almost cruel to it when it doesn't act like the actual Pearl.
* ViewerGenderConfusion: Many viewers assumed Pearl was going to be male due to her haircut and flat chest.
* WhatTheHellCastingAgency: Not in a bad way, but an odd way. The voice cast is a offbeat gathering of teen stars, pop singers, and radio personalities. It's almost as if a bunch of old friends in the entertainment industry had a reunion.
** Music/NickiMinaj as Sugilite in particular surprised many.
* TheWoobie:
** Connie. She constantly moves from town to town because of her dad's job, and, as a result, has no friends to keep in touch with, something which drives her to tears when she thought [[DyingAlone nobody (but her parents) was going to miss her if she drowned in the ocean]]. Which makes Steven reaching out to her another one of the particularly poignant SugarWiki/HeartwarmingMoments.
** Steven. He tries so hard, and it's impossible to not feel bad for him when he messes something up. There's also the fact that he never got to know his mother.
** Amethyst on occasion, especially in the episode "Tiger Millionaire". She doesn't act like it, but she clearly takes Pearl and Garnet's criticisms to heart.
** Definitely Lapis Lazuli, and very much of the [[WoobieDestroyerOfWorlds destroyer-of-worlds]] variety. She was trapped in a mirror for who knows how long and wants to go home so badly that she tried to use the entire ocean as a tower to reach it, but ultimately can't due to her damaged gem.
* WhatAnIdiot: During Onion's rampage, Pearl tells Steven basically what the viewers were thinking at the time: that he could have easily used the Replicator Wand to replicate Ranger Guy instead of giving the device to Onion.
-->'''Steven:''' ''({{facepalm}})'' DANG IT!
** Starting to happen frequently with Amethyst.
* WhatDoYouMeanItsForKids: A number of moments could qualify the show for this, but the most notable examples would probably be Steven almost aging himself to death or Pearl being stabbed through the gut and temporarily dying.
* WinBackTheCrowd: When Cartoon Network put the show on a three month hiatus, fans got worried. Then the network revealed that not only did they add more episodes to the first season, they also renewed for a big second season. The result was that Steven Universe would have a total of ''104'' episodes[[note]]52 half-hours[[/note]] for its first two seasons. Such news put the fans' minds at ease.
