History YMMV / StevenUniverse

** Both Ruby and Jasper are often confused for male due to their muscular designs and aggressive personalities.

* FanartAtFirstSight: When the ''End of an Era'' artbook was leaked online, the thing fans immediately latched on to were concepts for both Morganite and [[FusionDance Rhodonite's coponents]], who all received multiple pieces of fanart before the day ended, and many comments about how cute Rhodonite's Pearl and Ruby were or how many were surprised that Morganite resembled Aquamarine and not Emerald.

** There doesn't seem to be any evidence that [[ShesAManInJapan some foreign language dubs made Ruby a male character]] to erase the lesbian romance between her and Sapphire. As far as anyone can tell, it seems that this started as just speculation of how a localization trying to tone down the show's homosexual content ''could'' do it, which then got talked up so much that people started to just assume it had actually happened, especially after Ruby wearing the dress at her and Sapphire's wedding was suspected to be specifically designed to prevent it.
** Fusion is a metaphor for sex, debunked repeatedly by the Crewniverse; Fusion is a metaphor for relationships of ''all'' kinds, be it familial, plantonic, romantic, etc. The fact some {{Fusion Dance}}s are sexually provocative is just a result of the characters' personalites and their relationships with each other.

** In the show itself, the Diamonds [[OrcusOnHisThrone aren't very proactive]], being content to leave the Earth alone in favour of running their empire on Homeworld or [[EvenEvilHasLovedOnes grieving over Pink Diamond's death.]] If anything, their modus operandi is far closer to ''colonialism'' than actual Nazism, though it didn't make them [[EvilColonialist any less evil or excuse their actions.]]

* OneTruePairing: Lapidot, the pairing of Lapis with Peridot. It started off as a CrackShip (with fans immediately shipping them once Peridot appeared) but has gotten more and more popular, becoming the most popular ship with both characters, especially after Peridot has her HeelFaceTurn. The fact that they're now roommates and getting along smoothly as of "Beta" has cemented its place. The ship is easily one of the most vocal in the fandom, possibly even the most vocal out of any non-canon pairing besides Steven and Connie themselves.

* LauncherOfAThousandShips: Unlike the rest of the cast, who usually have one or two popular pairings, Pearl has multiple, including Rose, Amethyst, Garnet, Bismuth, Mystery Girl, and Pink Pearl.

* SuperCouple:
** Steven/Connie, their extremely adorable friendship [[ChildhoodFriendRomance slowly blossoming into a romance]] over the course of 5 seasons, a movie and a miniseries, they showed potential as a BattleCouple and the fandom went into a collective {{Squee}} when they ''finally'' kissed (on the mouth) in the finale of ''Steven Universe: Future'', with only a few complaining that it wasn't a BigDamnKiss. Shipping Steven with anyone ''but'' Connie is generally frowned upon, especially when [[NoYay Steven's partner is a Gem]].
** Sapphire/Ruby has not only become almost universally accepted by the fandom, but was [[WordOfGod confirmed]] to be ''canon'' by the storyboard artist of "Jail Break".

* DontShootTheMessage: A common focal point amongst the show's detractors. While many people would agree that the series' main message—violence is not the answer and pacifism is always an option—is a deeply meaningful one, there's a rather large BrokenBase over how the message is presented. To detractors, Steven managing to [[HeelFaceTurn redeem some of his enemies]] by having a heart-to-heart with them is plausible enough…but when he starts redeeming all of them, up to the point where he manages to redeem ''[[BigBad the Diamonds]]'', who are shown to be ANaziByAnyOtherName GalacticConquerors, it just feels ridiculous. This unfortunately makes the message come across less as "always try to make peace with the enemy if you can" and more as "the enemy will absolutely redeem themselves if you just talk it out". It's probably safe to say that in RealLife, this has not proven to be the case, as sometimes there will be people that are simply beyond reasoning with, no matter how hard one may try. Even a few fans will admit that the message could have been better presented as a result.

* ItsShortSoItSucks: One of the most common complaints about the show is its eleven minute run-time, which makes several episodes too short to properly tell their stories, and instead makes them feel rushed.
** "Story for Steven", the episode showing how Greg and Rose first met is sometimes said to be too short. While what the episode does have is well-liked, numerous people feel that it doesn't delve deeply enough into Greg and Rose's relationship, and that it doesn't properly explain why Greg was so quick to give up his music career for her. This is lightened when it was confirmed this episode was intended to air before "The Message", which would have given the episode more of a punch as opposed to its somewhat out-of-place slot in season 2.
*** Mediated with the follow-up flashback episode "We Need to Talk", where Greg and Rose both acknowledge that they rushed into the relationship and needed to work on it harder.
** Even though "Mr. Greg" is easily the most well-liked episode from the first week of "Steven's Summer Adventures", there are a few fans (who do like it) that say it would've benefited more from being a full half-hour rather than the usual 11 minutes.
** The arc with Jasper from "Alone at Sea" through "Earthlings" which built up her Corruption in the latter. The biggest problem with these episodes that several people had was that she would only show up for the last few minutes of most of them (with "Gem Hunt" being the worst offender) with the show clearly making a far bigger deal regarding her presence and how much of a threat she was to Steven and company despite the fact that most of the Crystal Gems have been able to easily fend her off with Fusion.

* EvilIsSexy: The Diamonds are already incredibly beautiful-looking in their own league, but fans often prefer to give special attention to Blue Diamond, possibly for her, uh, "assets" and [[ArousedByTheirVoice her soothing Irish accent.]]

** One of the biggest criticisms about the shows ending is [[spoiler:White Diamond's sudden HeelFaceTurn once it becomes apparent that Pink Diamond is truly gone and the realization that she's not as flawless as she thought she was.]] Many people found it pretty abrupt and unrealistic, feeling it a copout to a climatic battle that had been built up towards throughout the show. However, the show has had a history of enemies pulling a HeelFaceTurn and making it apparent that violence isn't always the answer. The difference was the lower stakes of older episodes generally made it more believable, and Steven at least got a good amount of time with the character to make it feel more realistic.[[note]]Lapis was willing to stop her plans [[BecauseYouWereNiceToMe because Steven was the first person in CENTRIES to treat Lapis like an actual person]], and Peridot had an entire arc of the show dedicated to her HeelFaceTurn.[[/note]] This is on top of the fact that there were several characters where attempting to get through to them flat-out ''failed'', and the Gems would be forced to throw down with them for the safety of the planet.[[note]]Jasper outright rejects Steven's attempt to befriend her, believing Steven is just trying to manipulate her for his own purposes.[[/note]] [[spoiler:With White Diamond however, even though Steven managed to get through to Yellow and Blue, White seemed like an insurmountable force that would refuse to listen to reason, and in the end outright resorted to ''brain washing'' Gems in order to keep them in line. As such, her sudden HeelRealization in the finale ends up coming off more as a case of OnlyTheAuthorCanSaveThemNow, as White had effectively ''won'', with the Crystal Gems and fellow Diamonds completely under her control, and Steven failing to get through to her until White saw with her own eyes that Pink Diamond was well and truly gone by removing Steven's Gem from his body. The sudden abruptness of this compared to earlier cases of this trope ended up breaking the WillingSuspensionOfDisbelief for many, resulting in a finale that many [[BrokenBase have mixed feelings about]].]]

* AmericansHateTingle: While the show is [[GermansLoveDavidHasselhoff widely loved in Latin America]], the titular character is loathed in that same region. Latin Americans generally regard Steven as a MemeticLoser, with fan works often portraying him as a wangsty fool who has no combat abilities outside of [[SwiperNoSwiping whining and pleading with his foes to reform themselves...which somehow works]]. Memes depicting Steven as negative or ineffectual compared to other, more popular characters, in the vein of the "Chad vs. Virgin" meme, are popular in Latin America. Latin Americans even refer to Steven by the hostile nickname "Gordo Mamón", which literally translates into English as "Fat Sucker". While Steven is often viewed as a VanillaProtagonist in the rest of the world compared to the Crystal Gems and is far from the most popular character in those regions, he typically isn't outright hated like he is in Latin America. It goes to the extent that the reveal of Steven as a playable character in VideoGame/MultiVersus led to excited posts from Latin Americans on social media about how much they were looking forward to playing the game just to be able to beat up Steven.

** Lion and Lars are not immortal. They're most likely ageless, but they, like the Gems, can still get hurt and die.

* WhatTheHellCastingAgency: Not in a bad way, but an odd way. The voice cast is a offbeat gathering of former teen stars, pop singers, musical theater performers, 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, as her voice for Sugilite sounds almost exactly like the voice actress for Amethyst. Another big issue is how hiring such big names as the Fusions [[ActorExistenceLimbo severely limits how much they can be used]], beyond brief appearances where they don't speak, compromising how much personality they can show.
