History Characters / StevenUniverseDiamondAuthority

* AntagonistAbilities: They all have powers that can easily neutralize other Gems without even allowing them to fight back. Blue can immobilize anyone using her [[EmotionBomb psychic aura]], Yellow has an AgonyBeam that can instantly overload the target with pain and destroy their physical form, [[spoiler:Steven/Pink can enter the minds of other beings and [[DemonicPossession forcibly take control of their bodies]], along with [[MakeMeWannaShout a scream that can shatter walls and crack certain parts of a Gem's physical form]]]], and White has EyeBeams that can [[VillainOverride assimilate a Gem's mind]] allowing her to control their bodies and project her powers through them. When all of the Diamonds combine their powers they unleash a FantasticNuke that can annihilate all Gem life from a planet, and even when one of the Diamonds was missing they were still able to corrupt every gem on Earth. [[spoiler:As of "Steven Universe: Future", the Diamonds no longer do this, as they've have time to go through their own self-exploration now that they're no longer the rulers of the Gem Homeworld, and have developed new abilites that contrast their original powers.]]

* PersonOfMassDestruction: At least when several are together, they're able to corrupt an entire planet of Gems by themselves. And if Blue and Yellow's demonstrations of power during [[Recap/StevenUniverseS5E2TheTrial "The Trial"]] [[spoiler:and Rose's wide variety of abilities]] are any indication, they aren't too shabby on their own, either. [[spoiler:Taken up to eleven in [[Recap/StevenUniverseS5E23Reunited "Reunited"]], where Blue and Yellow are shown in combat for the first time. Blue's EmotionBomb completely disables the Crystal Gems and almost allows her to [[CurbStompBattle curbstomp]] them without raising a finger, she casually shatters Rose's sword with one hand like snapping a toothpick, and when it comes to magical brute force she has more firepower than ''most Gem warships''. Yellow, meanwhile, effortlessly tears her way out of her crashed ship with her bare hands and is disturbingly fast for a being of her size, closing the distance between herself and Steven in less than a second and slamming him into the ground through his shield. Both also easily shrug off being hit with entire buildings and their own ships. And while Pink's powers have proven to be largely defensive, "Pink Steven" proved that Pink Diamond's powers, when fueled by anger, can destroy the surrounding environment [[MakeMeWantToShout by screaming]] and brush off the attacks of all three other Diamonds combined [[NoSell as if they were nothing]].]]

* TookALevelInKindness: [[spoiler: After Steven convinces them to heal all of Earth’s corrupted gems, they become far more benevolent people with some heavy implications they’re undoing all of the damage they’ve caused over 6000 years such as Yellow Diamond being seen restoring shattered Gems, liberating all colonies they’ve formed, stepping down as leaders and giving Gems on Home Planet democracy and freedom, and repurposing their powers that will benefit gemkind. While Steven is still clearly uncomfortable being around them given understandable reasons and they’re still flawed people, their attempts to change are sincere and they legitimately care about Steven.]]

* CripplingOverspecialization: With the exception of Steven/Pink, their main AntagonistAbilities and other magic powers only work on Gems. Against anything else, their abilities are completely ineffective. However, this is somewhat downplayed as they are physically incredibly powerful and durable, so it's not like they really need to rely on their magic in combat.

* LaserGuidedKarma: In a huge way. [[spoiler:For emotionally abusing and neglecting Pink Diamond for eons, they ended up with a humiliating, catastrophic rebellion that significantly crippled their empire, and Pink, who was mistaken to have been murdered by the Rebellion's leader, was actually alive all those years but died for real when she gave birth to Steven a mere decade and a half before the Diamonds returned to Earth. This means that the Diamonds lost their chance for reconciliation; Pink appears to have died believing herself unwanted and unloved by her fellow Diamonds who would be better off without her, and the other Diamonds have to live with the fact that they will never be able to apologize for the harm they inflicted on their permanently estranged family member. ''VideoGame/UnleashTheLight'' reveals that [[HowTheMightyHaveFallen they have been stripped of their roles as Homeworld's leaders by Steven]].]]

* CatchPhrase: [[https://www.youtube.com/watch?v=YH4bM5nCZbY "That's enough!"]] or a variation of it.

* {{Leitmotif}}: Fitting for otherworldly alien leaders, they are accompanied by [[https://www.youtube.com/watch?v=4iYWc2WcBuM an unmistakable synth surge]], [[https://twitter.com/surasshu/status/685538183501721600 made to sound "non-musical"]]. It's an auditory representation of the Diamond Authority's emblem: one high note, two identical mid-notes, one low note. Each Diamond has a distinctive variation of the theme.

* TheWomanWearingTheQueenlyMask: Despite outwardly portraying themselves as all-powerful, perfect, and unbreakable, in private, Yellow and especially Blue Diamond are deeply affected by the loss of their youngest family member, Pink Diamond, and deal with it in their own ways. [[spoiler:And Pink Diamond herself ''hated'' what the Gems were doing to the planets they colonized, but couldn't express it as a Diamond.]]

** Each Diamond represents and uses a different form of abuse: Yellow Diamond inflicts physical abuse, Blue Diamond inflicts emotional abuse, and White Diamond inflicts [[{{Gaslighting}} psychological]] [[MindManipulation abuse.]]
*** Pink Diamond can also be said to represent [[ParentalAbandonment abandonment]], especially as more details about her are revealed.

* AntagonistAbilities: They all have powers that can easily neutralize other Gems without even allowing them to fight back. Blue can immobilize anyone using her [[EmotionBomb psychic aura]], Yellow has an AgonyBeam that can instantly overload the target with pain and destroy their physical form, [[spoiler:Steven/Pink can enter the minds of other beings and [[DemonicPossession forcibly take control of their bodies,]] [[MakeMeWannaShout along with a scream that can shatter walls and crack certain parts of a Gem's physical form]]]], and White has EyeBeams that can [[VillainOverride assimilate a Gem's mind]] allowing her to control their bodies and project her powers through them. When all of the Diamonds combine their powers they unleash a FantasticNuke that can annihilate all Gem life from a planet, and even when one of the Diamonds was missing they were still able to corrupt every gem on Earth. [[spoiler:As of "Steven Universe: Future", the Diamonds no longer do this, as they've have time to go through their own self-exploration now that they're no longer the rulers of the Gem Homeworld, and have developed new abilites that contrast their original powers.]]

** White Diamond, as the brightest of the Diamonds, has [[LightEmUp light-based attacks]] [[EyeBeams which can be shot from her eyes]], [[TheCorrupter causing any Gem that's hit to fall under her control]], [[EmptyShell basically acting as an extension of herself]].

* EvilMatriarch: Peridot describes them as "matriarchs". The Diamonds are feminine and the "parents" of the other Gems, [[BizarreAlienReproduction loosely]] [[MonsterProgenitor speaking]], but [[WeHaveReserves they're definitely not optimistically motherly toward them]].

* GoodFeelsGood: As of ''Future'', [[spoiler:they are shown to be much happier and willing to use their newfound powers to ''help'' other Gems, in contrast to [[BeingEvilSucks how they felt]] [[TheChainsOfCommanding as dictators]].]]

** In [[WesternAnimation/StevenUniverseTheMovie The Movie]], White, Yellow and Blue have since put Steven's philosophy of peace and free-expression into practice, but [[ReformedButNotTamed it is left vague whether they actually believe in all of it or if they are just doing it because it's what Steven wants,]] [[WantsAPrizeForBasicDecency citing the fact they are no longer invading and conquering planets and are trying to be nicer as reason so that Steven would stay with them.]] [[spoiler:''WesternAnimation/StevenUniverseFuture'' shows otherwise, as the Diamonds appear to be happier without their empire and putting Steven's philosophy of peace and free-expression into practice, as the Diamonds have developed new powers that contrast their original abilities, [[HealingHands which they use to help other Gems]] [[MustMakeAmends and undo all the damage they've caused for eons.]]]]

* IronicName: Diamonds are seen as symbols of innocence and the integrity of moral values. A lot of the tropes listed here beg to differ. [[spoiler:Interestingly enough, Steven — who [[TomatoInTheMirror turns out to be]] [[HalfHumanHybrid half-Diamond]] himself — fits those traits like a glove.]]

* NotNowKiddo: [[spoiler:A major element that led to the falling out of Pink's relationship with the older Diamonds. Being constantly dismissed, ignored, and having her own authority being treated next to nothing was what led Pink to secretly lead a rebellion, thinking her family would be better off if she was dead. [[DramaticIrony She was very wrong.]] [[Recap/StevenUniverseS5E26TogetherAlone "Together Alone"]] also has Blue telling "Pink" to stop "fooling around".]]

** Before their HeelFaceTurn, each Diamond (sans Pink Diamond) represents and uses a different form of abuse: Yellow Diamond inflicts physical abuse, Blue Diamond inflicts emotional abuse, and White Diamond inflicts [[{{Gaslighting}} psychological]] [[MindManipulation abuse.]] After their HeelFaceTurn, they represent and use three (sometimes superficial) solution to mental healing: Yellow is "changing appearence or making a makeover", Blue is "medication" and White is "taking it out on others".

* BreakingTheCycleOfBadParenting: [[spoiler:White, Yellow, and Blue Diamond were rarely anything but abusive to their subjects, and didn't treat Pink Diamond much better. Considering Pink Diamond has close to a OneHundredPercentAdorationRating either as herself or Rose Quartz, and how (albeit posthumously) Steven was never abused by the Gems or Greg, it's clear she stopped it, though if her treatment towards Pink Pearl and Spinel is any indication, she averted this trope [[CharacterDevelopment at first]].]]

* MadGod: Despite being {{Physical God}}s in comparison to normal Gems, the Diamonds have all the issues any mortal would, including ''mental issues''; Yellow is a narcissist with a HairTriggerTemper, Blue is a [[TheEeyore hyper-emotional wreck whose depression leaves her sobbing all day]], and [[spoiler:White is a weird, robotlike HumanoidAbomination who practically ''lives'' in the UncannyValley and comes off as [[{{Cloudcuckoolander}} more than a little insane]].]] All of them are callous {{Mood Swinger}}s prone to massive DisproportionateRetribution. Pink was the only exception, [[spoiler:but even she was quite naïve and didn't seem to truly understand what it meant to be a leader/god.]]

** Yellow and Blue Diamond: The Mother(s), being the ones mainly in charge of looking after and guiding the Child (Pink).
