History YMMV / YoungJustice

* TheScrappy: Slobo/Lil' Lobo was a polarizing figure among fans and writers. The final issue of the series saw him transformed [[AndIMustScream turned into a living statue]] and he has not been seen or mentioned since. DC editor-in-chief Creator/DanDiDio reportedly despised the character, and claimed that he nearly ruined the original Lobo. Of course, [=DiDio=] disliking a character [[ComicBook/{{Nightwing}} hasn't]] [[ComicBook/WallyWest always]] [[ComicBook/Batgirl2000 translated to]] [[ComicBook/Batgirl2009 similar feelings among fans]], but unlike most, there has been very little fan outrage due to this grudge.

* EnsembleDarkhorse: Impulse.

* CompleteMonster: [[EvilOrphan William "Billy" Hayes]], better known as [[NamesToRunAwayFrom Harm]], was a [[TeensAreMonsters teenage supervillain]] and a complete sociopath. Adopted by loving parents, Harm initially terrified his adoptive younger sister Greta, her fears proven right when Harm [[ElectrifiedBathtub murdered her in her bathtub]] to seal a demonic pact and give himself superpowers. His goal was to become the world's greatest murderer, and he decided to hunt down and destroy all the kid heroes before moving on to the big leagues. He captured Red Tornado and reprogrammed him as a suicide bomber against Pope John Paul II to make a name for himself in the supervillain community. When his father, realizing what he was, killed Harm with a gunshot to the back, Harm's spirit later returned. He [[DemonicPossession possessed his father]] and used his body to enact more evil deeds, none more enjoyable to him than screwing with Greta, now the ghostly heroine Secret, by making her think her father never truly loved her. When defeated, Harm, out of sheer spite, forced his father to throw himself into one of the fire-pits of Apokolips while Harm possessed him to kill them both.

[[folder:General]]
* AdaptationDisplacement: The animated series has far eclipsed the original [[ComicBook/YoungJustice comic]] in the eyes of many. However, it's [[InNameOnly hardly an adaptation]] as they really only share the basic concept of focusing on a young team of superheroes in common, and the name was essentially given to them. Still, mention "Young Justice" and you can be sure that this is what will come to mind for most.
* {{Adorkable}}:
** Robin has his moments, especially when he gets nervous and flustered when put in charge of leading team alpha and his facial expressions to his teammates' antics.
** After Red Arrow spends the first two seasons as rather uptight and angry, by the third season his demeanor's completely changed. He makes bad puns and jokes about diarrhea, is openly worried about his insurance premiums when Brick attacks his car, and gets adorably flustered during his time with the moms in "Home Fires." In short, he is such a ''dad''.
** Zatanna in Season 1, at least, where she shares Robin's love of wordplay and occasionally mixes BuffySpeak into her magic spells.
** Wonder Girl's cluelessness, general clumsiness and idolization of Wonder Woman make her very endearing.
** Wally's expansive scientific knowledge is appealing to many fans.
** Thirteen gets so excited about visiting an alien planet that she ''jumps'' into a Boom Tube, and accidentally throws off the destination with her magic.
** AmnesiacsAreInnocent is in full effect for Violet, which means Halo/Violet is curious, excitable, and seemingly oblivious to many social cues ([[DistractedByTheSexy like idly commenting on Brion's naked body]]). She's endearingly awkward.
* ArcFatigue: For some fans, the unresolved continuing grand scheme of [[LegionOfDoom the Light]] became this by the end of the series - and since the series was revived, so has the fatigue.
* SugarWiki/AwesomeMusic: The YJ [[https://www.youtube.com/watch?v=PjLyg8S1iXY OP theme]] from Season 1.
** [[https://www.youtube.com/watch?v=CiVCO7yVWZE The YJ Phantoms OP theme]] for Season 4 uses an electric themed remix.
* BetterOnDVD: This feeling of arc fatigue was undoubtedly magnified with the constant ScheduleSlip the first and second seasons were subject to on TV, particularly the first. Watching the episodes as they aired with a lot of unexplained hiatuses in between could easily make one feel lost or frustrated, and binge-watching them does a lot to alleviate this. The high viewership on Creator/{{Netflix}} was a major factor in the show's renewal on the Creator/DCUniverse streaming service, and the release schedule of three new episodes a week all but says they're meant to be binged, being as plot-heavy as ever.
* CompleteMonster: See [[Monster/DCAnimation here]].
* EvilIsCool: [[LegionOfDoom The Light]] get a lot of love for being a group of {{Magnificent Bastard}}s and A-list supervillains who run circles around the heroes. In particular, [[spoiler:ComicBook/LexLuthor (an AffablyEvil BadassInANiceSuit)]] and [[spoiler:ComicBook/VandalSavage (a compelling GeniusBruiser with an interesting philosophy)]] stand out.
* FandomRivalry: Ever since the show began, there's been a rivalry of sorts between fans of this show and fans of ''WesternAnimation/TeenTitans'' for their different approaches to the DC teen team concept. Related to this, the more serious tone compared to the ''Teen Titans'' cartoon is the key or overarching issue some fans have, since many other issues they have ultimately stem from it, and they see ''Teen Titans'' as just more "fun". Others prefer the more serious tone because ''Teen Titans'' was too lighthearted much of the time for them. This became HilariousInHindsight when ''WesternAnimation/TeenTitansGo'' (a comedy show, unlike the others) drew a lot of flak for not being the proper ''Teen Titans'' revival the fans wanted[[note]]Though it was finally teased in ''WesternAnimation/TeenTitansGoToTheMovies''[[/note]] and ''Young Justice'' characters were used in a SelfDeprecation episode to tell the Titans off.
* FriendlyFandoms: With the ''Series/Titans2018'' fanbase, since they're sister shows on the Creator/DCUniverse as the first two originals announced, and both were ScrewedByTheNetwork in the past (CN canceled ''Young Justice'' out of nowhere, TNT prevented ''Titans'' from ever being made on their network). Many fans of either often share the same communities.
* HilariousInHindsight: There was a five-year TimeSkip between seasons 1 and 2. Season 3 debuted five years since the show was canceled.
* IAmNotShazam:
** WordOfGod says [[http://www.s8.org/gargoyles/askgreg/search.php?qid=13322 "Young Justice" is just the name of the show]] while the team is just "the team". Thus they have yet to be [[TitleDrop called "Young Justice" on-screen]]. In-universe, since the team isn't public like the Justice League, it doesn't get to have a "fancy name." This also further differentiates the team from the original Comicbook/YoungJustice of the comics.
** Also, officially speaking the teams led by Nightwing and Batman have no names, and have yet to be truly called "Outsiders" and "Batman Incorporated", respectively. For the former, they've been referred to as being "outside" the law as a nod, and for the latter, they've been called that twice by Black Lightning, but only as a disparaging remark. Still, just about everyone (including this wiki) refers to them as Outsiders and Batman Incorporated, because having "The Team", "Nightwing's team" and "Batman's team" just doesn't quite cut it.
*** This becomes even more complicated in the latter half of Season 3, where Beast Boy's newly created 'public' team is referred to by him as 'Outsiders', and Nightwing's team that had the spotlight in the first half has seemingly now had the majority of its members rejoining the old team or joining Beast Boy's new team, barring Nightwing, Black Lightning, and Cyborg[[note]][[spoiler: Until Cyborg joined the Outsiders later on, Nightwing finally returned to the Team, and Black Lightning became the Justice League's new leader]][[/note]]. One could make the case that the "Outsiders" of the title is meant to refer to both teams, with Nightwing's team in the first half of the season being 'outsiders', while Beast Boy's in the second half is the Outsiders.
* MagnificentBastard:
** ComicBook/VandalSavage is the leader and founder of the Light. Intending on creating a secret group to counter the ComicBook/JusticeLeague, Savage directs most of its greatest moves, such as forming alliances with various villain factions, continuously using fronts and proxies so when the League defeats them, the Light remains undetected. Making alliances with alien groups like the Reach and Apokolips, Vandal engineers the near downfall of the world and at one point completely enslaving the Justice League and sending them off-world to fulfill the Light's purposes, framing them as criminals on another planet. Bent on creating a world of conflict where humans will be forced to evolve and adapt, Vandal constantly shows why he is worthy of being the head of the Light.
** ComicBook/LexLuthor is as charming and intelligent as ever. Forming Project Cadmus to create Superboy with his own DNA, Lex constantly stays a step of the heroes, even filling Superboy himself with doubt over his true place. Organizing a peace treaty between the countries of North and South Rhelasia, Lex manipulates events so both will [[GenghisGambit unite under the Light's guidance]] and constantly proves invaluable in assisting Vandal with the best of the Light's schemes. Upon realizing the danger of the Reach, he and Vandal help to form counter measures against them, ending the second season by [[KarmaHoudini escaping completely free of their own crimes]] and proving why Lex is always a match for any adversary.
** [[NobleDemon Jade Nguyen]] is the supervillain [[CheshireCatGrin Cheshire]], the daughter of Sportsmaster and the older sister of Artemis. Serving as an assassin for the League of Shadows, Cheshire frequently encounters her sister on contracts for the Light, always managing to evade capture but [[EvenEvilHasLovedOnes taking the time to save Artemis]] when her life is in danger. Later marrying Will Harper, Cheshire discovers the location of the real Roy Harper and assists Will in rescuing him. Professional enough to work with her hated father in order to avenge Artemis' death, the two storm Black Manta's base and come within seconds of killing Aqualad, before learning of Artemis' survival and easily staging an escape to keep her cover intact.
* OlderThanTheyThink:
** Superman's initial reluctance to form a relationship with Superboy has been met with criticism as being out-of-character for the Man of Steel. However, Superman has historically had a rather hands off approach to the younger members of the Super family in the comics. In the original Supergirl stories he had her put into foster care and in post-Crisis, he left her training to the Amazons. With Superboy, Clark initially wanted no part in raising him (and the feeling was mutual on Conner's end) but eventually they did start to bond as is the case with the show. Even then, Clark left Conner to be raised by Jonathan and Martha Kent.
** Cheshire's more sympathetic depiction has been criticised by some comic fans as her being softened by the show. However, Jade was more of a PunchClockVillain and NobleDemon in her original appearances. She once helped stop a group of racists who wanted her to kill a black civil rights activist and was shown to care for Lian. She became the AxCrazy DragonLady she is known for being in the comics after the story in Deathstroke's book where she nuked Qurac but prior to this she had more in common with her depiction in this show.
** Some fans have taken issue with the highly unsubtle attempts in Season 3 to create similarities between Lex Luthor and Donald Trump. While it doesn't excuse the quality of the writing, this is not the first time Lex Luthor has been modeled after Donald Trump. John Byrne modeled Post-Crisis Lex Luthor after Donald Trump and Ted Turner (“evil corporate executives”, as he said). There was even a one-shot comic called Lex Luthor: The Unauthorized Biography, which was clearly modeled off The Art of the Deal. Granted, that was always based off him as a businessman, not a controversial political figure.
* OneSceneWonder: Cameos abound in this show due to the [[LoadsAndLoadsOfCharacters loads and loads]] ''[[UpToEleven and loads]]'' of characters from all across the DC Universe, making their appearances special for avid DC comics fans. Particularly if they've never been animated before.
* SpiritualAdaptation:
** The show is really more like the ''ComicBook/TeenTitans'' comics, thanks to its heavy focus on plot and character drama, than its [[ComicBook/YoungJustice namesake]].
** Additionally, in some ways it's TruerToTheText than the beloved 2003 ''WesternAnimation/TeenTitans'' series. It's played entirely straight as opposed to being lighthearted and comedic (though that's not to say the original couldn't have serious moments either), has heavier themes, a focus on romance, and features an expanding and revolving lineup as opposed to a [[AdaptationDistillation core five]] like what 2003 series had, which brings it in line with how the Titans were portrayed as in the comics. Furthering this, the founding members include Robin, Kid Flash, and Aqualad (albeit, a different one) much like the original founding Titans.
* TheyChangedItNowItSucks: Some fans of the ''Comicbook/YoungJustice'' comics give this show flak, particularly because it's [[InNameOnly using the name]] while being closer in sensibility to the more serious ''Comicbook/TeenTitans'' comics. In the same way, the ''WesternAnimation/TeenTitans'' cartoon is closer to the less serious ''Young Justice'' comics, and caught some flak of its own for that. Still, roster additions in season 2 increased the number of ''Young Justice'' comics characters.

[[folder:Seasons 1 and 2: A-G]]
* AlternativeCharacterInterpretation: [[AlternativeCharacterInterpretation/YoungJustice It now has its own page.]]
* AngstWhatAngst: Justified, but it's there. Jaime spends the most of his arc terrified of being a weapon for the Reach, and then [[spoiler:it finally happens]]. Jaime spent ''months'' trapped in his own mind, but by the time we get a look inside his head and he's developed a coping mechanism: throwing insults and snarks at the Ambassador. A bit of what we'd expect is demonstrated when [[spoiler:the Ambassador orders the Scarab to kill Impulse and Batgirl and he freaks out]], but otherwise it's pretty angst free. Jaime came out of the experience surprisingly well, in fact ''too well''.
* AlasPoorScrappy: Okay, admit it, you hate L'gaan because of so many reasons, but it’s hard to leave him in the dirt because M'gann left him. In fact, he may have probably went worse than Superboy because despite Superboy getting MindRaped, at least he and M'gann had a genuinely loving relationship, whilst L'gaan was selfishly used to repair M'gann's self-esteem.
* AntiClimaxBoss: Black Beetle throughout ''Invasion'' is TheJuggernaut who effortlessly [[TheWorfEffect worfs]] most of his opponents not named Blue Beetle. Then, the penultimate episode made him the DragonAscendant for the Reach, who takes over as BigBad for the finale with a plot to ''destroy the world''. In the final episode, he loses easily to Blue Beetle through weakness exploitation. This happens after roughly ''five minutes'', and the majority of the finale is about everyone undoing the damage before Earth can be destroyed, but he's already been taken out by that point. Some might be disappointed about how quickly he went down in his final appearance, all things considered.
* ArcFatigue: Besides the general issue with the Light, Season 1 in particular got a lot of flak for ending several episodes the same way, with the Light going "AllAccordingToPlan" even before their faces were revealed. Understandably, ''Manga/DeathNote'' ''keikaku'' memes were often invoked in response.
* AssPull: The Team's [[spoiler:Starro-Tech cure and vaccine]] in the first season finale. To elaborate, [[spoiler:the Light spent the entire season assembling the technology to create the Starro-tech mind control device to subjugate the Justice League, while the Team manages to procure a cure for it completely off-screen in the span of ''hours'', with the help of some Atlantean scientists who were minor characters earlier in the series.]]
* SugarWiki/AwesomeMusic: [[https://www.youtube.com/watch?v=ocA8drSsSco The first season's opening theme]] is the definition of short and sweet.
* AwesomenessWithdrawal: The many random hiatuses the show suffered did not help.
* BadassDecay: Superboy. When he first appears, he's shown to clearly be the overall strongest of the main characters, but as time went on, he kept getting subject to TheWorfEffect. It's especially bad in the second season when he's largely DemotedToExtra and can barely win a single fight, even losing against [[spoiler:Aqualad]] despite easily defeating him in the pilot.
* BaseBreakingCharacter:
** Miss Martian. A horrible abomination of a character, or a delightful breath of fresh air in a team full of jerks? Her CatchPhrase ("Hellooo, Megan!") isn't helping matters. [[spoiler:Though these turned out to be ArcWords as well, directly connected to her character issues (and indirectly, Beast Boy).]] As of "Earthlings", we have whether or not [[spoiler: her {{mind rap|e}}ing a Krolotean leader to get information was [[ThereIsNoKillLikeOverkill unnecessary and overkilling it]] or whether [[IDidWhatIHadToDo she did what she had to do.]]]] This latter behaviour also extends into her relationship with Superboy, with the disturbing implications of her abuse of power on him. It also doesn't help that his fresh clone status and her age and insistence on modeling her life and him after her favorite TV show can come across as child grooming.
** Artemis has her share of haters as well. An intriguing character (DarkAndTroubledPast, BrokenBird, [[spoiler:BadassFamily]] [[spoiler:[[TheFamilyThatSlaysTogether That Slays Together]]]]) or just a snotty bitch? You decide!
** The Light are either {{Magnificent Bastard}}s or {{Invincible Villain}}s, depending on who you ask.
** The Joker also suffers from this: some are criticizing how the show handled him, while others defend the show's take. Some are also annoyed he isn't voiced by Creator/MarkHamill (''WesternAnimation/BatmanTheAnimatedSeries'' et cetera) or Creator/JohnDiMaggio (''WesternAnimation/BatmanUnderTheRedHood'').
** Klarion the Witch Boy. It's not so much his personality as his role in being [[spoiler:a member of the Light]]. Even then, you have people saying he's a funny FauxAffablyEvil villain, and people who find him annoying.
** Dr Fate. Some fans consider him a KnightTemplar the League should have destroyed, others consider his actions, while harsh, both understandable and justified. Sharing an opinion on the matter among fans is bound to start a fight.
** Aqualad is either viewed as being an awesome [[TheStoic stoic]] leader, or a FlatCharacter who never expresses any emotion. There's also those who say Creator/GregWeisman is making him overly perfect at the expense of Dick (by making him leader instead of Dick, though this was remedied as of Season 2 [[spoiler:until TheReveal and finale arc]]) and Garth (by not having Garth becoming Aqualad before Kaldur). And then in Season 2 there's [[spoiler: his off-screen FaceHeelTurn.]] And ''then'' [[spoiler:this turns out to be [[FakeDefector fake]].]] And then there are those who feel he doesn't get enough of screen time compared to the other characters.
** Kid Flash is either viewed as a childish {{Jerkass}} (especially compared to [[WesternAnimation/JusticeLeague previous]] [[WesternAnimation/TeenTitans incarnations]]), or being one of the funnier and more genuinely likable characters on the show. However, some see the episode "Coldhearted", late in Season 1, as the point where [[CharacterDevelopment he gets some much-needed maturity.]]
** Lagoon Boy: Is he an obnoxious, brash jerk towards Superboy or is his behavior justified because Conner not-so-subtly belittles and picks on him because of his lingering feelings for Ms. Martian? Note that even though the base is broken on whether his behavior is justified, he's still [[TheScrappy rather disliked]].
** Nightwing's actions. Was he right to keep the team out of the loop? Was his plan too risky? Was he wrong for [[spoiler:kicking Arsenal off the team]]?
** Arsenal. Does he endanger the Team too much to settle his own agenda, or is he a ShellShockedVeteran who didn't get proper treatment for his obvious PTSD?
** Superman's refusal to help Superboy or spend any time with him at all during the first season rubbed a lot of people the wrong way and brought up some serious questions about this particular Man of Steel's morality and compassion. Also a divisive character for whether or not Superman was actually justified in feeling uncomfortable around Superboy, a clone made without his knowledge or permission for shady reasons, and wanting distance when Superboy did nothing to really merit such treatment.
* BigLippedAlligatorMoment: Captain Cold's appearance in "Satisfaction" served no purpose whatsoever and when confronted by the girls he gave up without bothering to put up a fight, with no explanation being given for what that had to do with anything.
* BrokenBase: The Season 2 TimeSkip divided fans over the new characters replacing most of the old team, as well by as its very nature. It's either a hackneyed plot device that only leaves them wanting more of the old team as they were, or an awesome way to hit the ground running plot-wise and introduce more DC characters who wouldn't be the right age in season 1. The fans remained divided for the duration of Season 2 over the GambitPileup of the heroes and villains, as the plot grew more and more complicated with more and more new characters being introduced, including a new villainous faction, the Reach. Some also felt that gradually revealing what'd happened over the previous 5 years gave the current events more impact and others thinking those past events would've been far more interesting if they'd been shown in chronological order and if not for the fact that half of them we only got told about rather than being shown at all.
* CrazyIsCool:
** Adam Strange quoting ''Literature/AliceInWonderland'' and "Literature/{{Jabberwocky}}" to escape the space gestapo.
** Joker attacking Mount Justice with an army of green, bomb-throwing monkeys!
* DieForOurShip: Lagoon Boy, and it only took a single episode.
* EnsembleDarkhorse:
** While people are [[BrokenBase divided]] about the characterization of most of the cast, particularly ComicBook/{{Superman}} and ComicBook/TheJoker, there's one character nobody dislikes: [[{{ComicBook/Shazam}} Captain Marvel]]. He's the [[FunPersonified most fun]] character in the cast and seems to be as popular with the fans--and even non-fans--as [[WesternAnimation/BatmanTheBraveAndTheBold AQUAMAN]] was.
** The runaways who were experimented on by the Reach (Eduardo Dorado, Jr., Tye Longshadow, Asami Koizumi, and Virgil Hawkins) achieved this after "Runaways". Virgil already had [[WesternAnimation/StaticShock a built-in fanbase]], being one of the most hoped-for characters since the show premiered. But Eduardo, Tye, and Asami, derived from ''WesternAnimation/{{Superfriends}}'', have already garnered plenty of fans on their own. That they're all TrueCompanions already helps.
** True to her fan-favorite status in the comics, Stephanie Brown may only get a brief cameo, but in the comics she's better known as [[Characters/BatmanAndBatFamily Spoiler, the fourth Batgirl and fourth Robin]]. Even if her appearance was [[AllThereInTheManual only confirmed by the credits]], she still got a lot of love. And then she was announced for Season 3 assuming her comic identity as Spoiler, and was immediately considered the "main course" of the three newcomers. Many also hope that her [[HeterosexualLifePartners BFF]] Cassandra Cain will be joining too now that she's been announced.
** "[[MemeticBadass Coffee Pot Guy]]", the unmasked manta trooper who offers Tigress a fresh pot of coffee in "Complications".
* EvilIsCool:
** Mongul, despite his limited appearance in Season 2, was extremely well-received by the fans. He effortlessly [[CurbStompBattle thrashes the Team without even trying]] and nearly becoming a [[spoiler: greater threat than [[BigBad The Reach]]]], all the while speaking in the smooth BadassBaritone of the legendary Creator/KeithDavid.
** Cheshire, for being a femme fatale, a formidable opponent, and a [[spoiler:loving big sister to Artemis, wife to Roy and mom to Lian]] in near-equal measure.
%%* EvilIsSexy: Cheshire, Harm and Queen Bee (It doesn't hurt that she shares a voice actress with [[WesternAnimation/{{Gargoyles}} Demona]].)
* FanPreferredCouple: A lot of this. For instance, there's a lot of preference for Artemis/Robin, as well as some Kid Flash/Robin.
* FanficFuel: [[spoiler:Kid Flash getting lost in the Speed Force]] is a surprisingly common starting point for ''YJ'' crossover fics given the possibilities it allows.
* FoeYay: Between Roy and Cheshire, especially on her part. [[spoiler:During the TimeSkip, they [[OfficialCouple get married and have a child]].]]
* FunnyAneurysmMoment: Try reading these lines of dialogue after [[spoiler:Wally dies in the season two finale]].
---> '''Robin'': '''(referring to Wally being in school)''' A moment of silence for our absent comrade.
---> '''M'gann''': Poor Wally...
** Beast Boy telling Nightwing "[[spoiler:No faking anyone's death for ''at least'' a year!]]" in "Summit"? ''Hilarious''. After the next episode, where [[spoiler:Kid Flash dies]]? Not so much.
** In addition: in the debut episode of Impulse, much fun is made of the fact that KF CantCatchUp to Impulse and The Flash when it comes to speed. In "Endgame", that inability to catch up results in [[spoiler:his death]].
* GeniusBonus: "Whelm" is, in fact, a real word all by its lonesome. It basically means the same as the colloquial meaning of overwhelm. (i.e., Overwhelm ''should'' mean whelm, but taken UpToEleven.)
* GrowingTheBeard: Some possible points:
** Around or after the middle stretch of the first season, especially Episode 19, "Misplaced", and after, when the show finally stopped suffering from Creator/CartoonNetwork ScheduleSlip and the plot development seemingly picks up the pace in time for the season 1 finale.
** The second season, where the original team members are now more mature and competent due to a TimeSkip, more mature themes are explored, and more stuff from the DCU is introduced. In particular the shipping, catchphrases and wangst are much reduced. The second season also has a full-season StoryArc, so the writers can focus on developing that instead of having to come up with a new plot for each episode.

[[folder:Seasons 1 and 2: H-O]]
* HarsherInHindsight:
** In-universe:
*** Most of Red Arrow's bits about how he can't trust [certain team member] because anyone might be TheMole becomes this by the end of "Usual Suspects" since [[spoiler:it's ''him'', and his tone of voice as he realizes this implies that he realizes that he was programmed to put suspicion on the new heroes, to turn suspicion away from himself]].
*** In "Infiltrator", Artemis says to Red Arrow, "Step into the light!" [[spoiler:Oh Artemis, you have no idea...]]
*** In "Terrors", when M'gann and Connor are disguised as Belle Reve inmates Tommy and Tuppence Terror and are attending a therapy session with Hugo Strange, M'gann tries to help out Connor's issues with how much Superman, his biological father, has been avoiding him by trying to bring up "father figure issues" that "Tommy" has, but Connor winds up snapping back that he doesn't want to live in her "stupid fantasy world where every problem's solved in half an hour". We then get a brief glimpse of an ''extremely'' hurt expression from M'gann before she turns away in a mix of guilt and discomfort. It's not until the later episode "Image", where we find out that [[spoiler:M'gann has modeled her entire Earth identity on an old TV sitcom she used to watch obsessively]], that we realize just how deep that comment accidentally cut.
*** Actually not that accidental: [[spoiler: In "Bereft", Miss Martian's mind repair on Suberboy is later revealed to have done "too much at once" and given him knowledge of her White Martian nature. Clips from ''Hello, Megan'' can also be seen during the mind repair, showing that he learned about that too.]]
*** In "Disordered", Dick Grayson expresses trauma over thinking like Batman and making huge risks/sacrifices, explicitly stating "that's not me." By "Darkest", he's pulling off gambits so unstable that the one person in the loop gives him a WhatTheHellHero speech.
*** In "Darkest", Wally starts doubting whether or not Aqualad really is a FakeDefector as they think he is. Come "Before The Dawn", it's revealed that he is, and always has been, on their side [[spoiler: via MindRape, courtesy of Miss Martian]].
*** In "Welcome to Happy Harbor", M'gann is hesitant to use her telepathic powers on Mr. Twister after using them on the other Team members. Dick/Robin tells her "It's okay to use it on the bad guys!" and she runs with it. By Season 2, she may have taken this [[MindRape a little too far...]]
*** Wally not being as fast as the Flash or Impulse. [[spoiler: In Endgame, it kills him.]]
*** Also, Wally tells Bart in "Summit" that he's gonna retire after all this is over. [[spoiler:He retires, all right. [[TemptingFate Permanently]].]]
*** Also relating to "Endgame", the hashtag for the Twitter storm for that week was "#[=HeroesNeverDie=]".
* HesJustHiding: [[spoiler: Wally's death in "Endgame" earned this reaction from many fans. It helps that WordOfGod describes a clarification of his fate as a spoiler.]]
* HeartwarmingInHindsight: When [[spoiler: the Scarab controlling Blue Beetle]] fights Impulse and Batgirl, he uses the NailEm attack to pin them against the wall relatively uninjured. [[spoiler:At the beginning of the season, the Scarab would advise Jaime to shoot through bone--it seems to have learned some compassion from Jaime since then.]]
** Lian's name becomes this in "Overwhelmed" when Artemis' full civilian name is subtly revealed via [[spoiler:a diploma on a wall]]. Cheshire gave her daughter her sister's middle name.
* HilariousInHindsight:
** In a funny coincidence, this version of Superboy was introduced at the same time that ''Series/{{Smallville}}'' was doing its own Superboy storyline, and the reactions of the respective Supermen to the existence of Superboy [[HappilyAdopted could not]] be more [[ThatThingIsNotMyChild opposite]].
** In "Bereft," Robin wakes up without his memories of the last six months, and yells "In ''September''?! What happened to March?" "Bereft" was the last episode aired before the six month hiatus... in March. "Targets" didn't officially premiere until... ''September''.
** Miss Martian tells Superboy to "Stop behaving like a character in a 70s Sitcom" during "Alpha Male", then several episodes pass, and during "Image", [[spoiler:this is shown to be HypocriticalHumor as we learn that her entire personality and appearance is based around that of a 70s Sitcom character. Not to mention that Conner's name--which she ''suggested''--is the name of her character's boyfriend from the same show.]]
** For the comic based on [[WesternAnimation/TeenTitans the original series]], in issue #45 one of the campers suggests that Beast Boy might be of Martian origin because he's green and shape-shifts. Beast Boy's counterpart in ''WesternAnimation/YoungJustice'' got his powers and green skin from receiving a blood transfusion from Miss Martian.
** Dick's retort that "The Batcave is crowded enough already" to the offer of being cloned in Season 1, only for the TimeSkip between the two seasons to establish Barbara as Batgirl and introduce Tim as the latest Robin, with Jason having died in between. Continues in season 3 as [[spoiler:Stephanie is now Spoiler after briefly appearing last season, Jason is alive, and Cass/Orphan/Batgirl and Damian are introduced.]]
** A preceding Blue Beetle (Ted Kord) is famous for [[HeterosexualLifePartners his very close friendship]] with time traveler Booster Gold. Come ''Young Justice'' and the current Blue Beetle has a developing bromance with another time traveler, Impulse.
** The episode "War" starts off with Superman not understanding the Rimbor judge's alien language. The ''WesternAnimation/GreenLanternTheAnimatedSeries'' episode that aired alongside this, "Babel", focused on Hal not understanding Kilowog and Razer's alien languages for nearly the entire episode.
** Assuming the Runaways' name really is a ShoutOut to [[ComicBook/{{Runaways}} Marvel team of the same name]], there were some amusing coincidences later on. Members of YJ's Runaways were introduced in ''Beneath'', an episode featuring an all-female mission, and their leader later got to join the Team, which is basically a sister team of Justice League. In 2015 the (second) leader of Marvel's Runaways joined ComicBook/AForce, an all-female sister team of Marvel's equivalent to the JL, the Avengers... that, [[http://www.cbr.com/bennett-assembles-battleworlds-mightiest-heroes-in-a-force/ according to]] WordOfGod, was directly inspired by a conversation Nightwing and Batgirl had in ''Beneath''.
--->I remember watching one of the DCU animated cartoons a couple years ago where they put together a team of female heroines to go fight a villainess. I think it was Dick Grayson who was talking to them on screen and he was saying something like they couldn’t send any male heroes to fight this villainess because she can control the minds of men. I believe it was Batgirl who sassed him back and essentially said, “Why are you trying to justify having a team of only women? No one would ever try to validate sending a team of only men.”
** In a 2001 issue of ''Wizard Magazine'' the casting-call section had then-current ''Titans'' writer Jay Faerber suggest Creator/KellyHu play Cheshire in a live-action ''ComicBook/TeenTitans'' film. Guess who ended up providing her voice in this ten years later?
* HoYay: [[HoYay/YoungJustice Has a page for it.]]
* HypeBacklash: Any person can claim this show was the second coming of superhero show greatness after the DCAU. However, [[https://www.youtube.com/watch?v=it4QNAVstxI not every critic]] is going to have the same opinion. (Skip to 33:09 for part on Young Justice). The fans of ''WesternAnimation/TeenTitans'' often compare it unfavorably to their show as well as the DCAU.
* IdiosyncraticShipNaming: ''Hoo boy!'' There's a lot of them. Pretty much every kind of ship naming convention was used in this fandom.
** Kid Flash (Wally West) and Artemis = Spitfire
** Superboy (Conner Kent) and Miss Martian (M'gann M'orzz) = [=SuperMartian=]
** Robin I, later Nightwing (Dick Grayson) and Zatanna = Chalant
** Cheshire (Jade Nguyen) and Red Arrow ([[spoiler:Clone!]] Roy Harper) = [=RedCat=] or Cheshroy
** Guardian III (Mal Duncan) and Bumblebee (Karen Beecher) = [=GuardianBee=]
** Tye Longshadow and Asami "Sam" Koizumi = Team Headbands
** Eduardo "Ed" Dorado and Asami "Sam" Koizumi = Vest Duo
** Lagoon Boy (La'gaan) and Miss Martian (M'gann M'orzz) = Angelfish
** Artemis and Red Arrow ([[spoiler:Clone!]] Roy Harper) = Longshot
** Wonder Girl (Cassie Sandsmark) and [[spoiler:Arsenal]] = Wonder Gun
** Wonder Girl (Cassie Sandsmark) and Blue Beetle III (Jaime Reyes) = [=WonderBeetle=]
** Robin, later Nightwing (Dick Grayson) and Artemis = Traught
** Blue Beetle III (Jaime Reyes) and Impulse (Bart Allen) = [=SpeedBuggy=] or [=BluePulse=]
** Artemis, Miss Martian (M'gann M'orzz), and Aqualad (Kaldur) = Symbiosi
** Wonder Girl (Cassie Sandsmark) and Lagoon Boy (La'gaan) = [=WonderChum=]
** Aqualad (Kaldur) and Red Arrow ([[spoiler:Clone]] Roy Harper) = Koy
** Captain Marvel (Billy Batson) and Zatanna = Mazahs
** Aqualad (Kaldur) and Artemis = [=SeaArrow=]
** Zatanna and Artemis = Snaibsel (respell it backwards)
** Superboy (Connor Kent) and Wonder Girl (Cassie Sandsmark) = Powerhouse
** Artemis, Robin I/Nightwing, and Kid Flash (Wally West)= Museum Heist (what you get when you rob the wall art)
* LauncherOfAThousandShips:
** [[TroubledButCute Superboy]], very quickly. Superboy/Aqualad, Superboy/Miss Martian, Superboy/Artemis, Superboy/Black Canary, Superboy/Wonder Girl.
** [[AdorablyPrecociousChild Robin]]. Yes, the 13-year-old one. Maybe it helps that his other canon counterparts in the comics and other media are the same way. UpToEleven when he becomes Nightwing.
*** And after seeing what happens in the "Players" arc in the ''Young Justice'' tie-in comic it becomes canon. Kisses from [[spoiler: Zatanna and Rocket. Sleeping with Bette Kane the night before his birthday. Implied to sleep with Batgirl the night of his Birthday. Four at least kisses in a ~24 hour period]]
** Artemis and Kid Flash get their fair share as well. They've been paired with each other, Robin, Aqualad, Superboy, Miss Martian, Zatanna, Red Arrow, and their respective main-stream comic love interests. And that's not even getting into [[OT3 threesomes]], mentor-shipping, or [[CrossoverShip crossover shipping]].
** Heck, ''anyone'' in this show basically plays this trope straight. Aqualad and Miss Martian aren't entirely spared.
* LikeYouWouldReallyDoIt:
** One of the problems with [[spoiler:"Failsafe"]]. In the opening thirty seconds, [[Franchise/GreenLantern Green Lanterns]] Hal Jordan and John Stewart are vaporized without warning. That would be pretty unbelievable in itself, but then in the ''next'' thirty seconds so are Comicbook/CaptainAtom, [[ComicBook/{{Shazam}} Captain Marvel]], ComicBook/MartianManhunter, Franchise/{{Superman}}, and Franchise/{{Batman}}.
** In "Depths", [[spoiler:Artemis dies in the opening]]. The episode covers the events leading up to this moment and the aftermath [[spoiler:and it's revealed that her death was a ruse.]]
** In "Darkest", Aqualad's threatens to [[spoiler:set off a pseudo-nuke and destroy Mount Justice, and kill Nightwing, Superboy, Wolf, and sphere]], which turns out to be a bluff. [[spoiler:Then Aqualad has Artemis use the ''real'' trigger, and Mount Justice is totally annihilated, though they survive]].
** Many fans predicted that Barry Allen/Flash was going to die by the end of ''Invasion''. Come "Endgame", [[spoiler:Barry doesn't die. However, Wally does]].
*** Greg Weisman qualified a lot of his statements with little phrases like "assuming everyone survives" and "if they survive," when talking about characters. A tumblr user once reblogged one of these statements adding, "And you're assuming we're stupid enough to believe you'd kill one of your characters off." Well...
* LoveToHate:
** G. Gordon Godfrey is one of the most insufferable characters in the series for his FantasticRacism attitude and hostility towards the Justice League. But fans also can't help but enjoy Creator/TimCurry's hammy performance and even rooted for him when he calls out the Reach Ambassador.
** Lex Luthor here is no less devious than his other counterparts. However, he comes off as too [[AffablyEvil charming and polite]] to truly hate.
* MemeticBadass:
** Robin, soon after the pilot premiered.
*** And thanks to [[spoiler:the events of "Depths"]], Nightwing just cranked up the dial several notches. We're talking on par with, possibly even ''better'' than [[MemeticMutation "Batman with prep time"]]-level schemes here.
** Aqualad developed into this over the course of season one.
** Sportsmaster, due to [[http://en.wikipedia.org/wiki/List_of_sports the implications of his name.]]
** Artemis in Season 2 is getting there. While everyone else is angsting or complaining, [[IndyPloy she's out getting things done.]]
** Mongul. While already holding badass credentials due to the CurbStompBattle he delivered to the Team and overpowering Black Beetle, fans attribute this to his [[Creator/KeithDavid voice actor]]
* MemeticMutation:
** The [[BuffySpeak words Robin creates]] by removing prefixes (such as "whelmed" and "aster" from the words overwhelmed and disaster).
** Superman will take his pie to go. *[[MundaneMadeAwesome dramatic background music]]*
** Robin hacked the motion sensors.
** Aqualad is the son of Advertising/TheManYourManCouldSmellLike.
** "X is a sport."
** It's hard to pin just one down, but there was a flurry of angry memes when the hiatus until January 2013 was revealed.
** "Now THAT'S a rutabaga!"
** Judging by pure gif saturation, Blue Beetle [[spoiler:whacking his HeterosexualLifePartner in the head with a rock]].
** Wally was a fan-favorite character in season one who was DemotedToExtra in season two, which resulted in a lot of "WHERE'S WALLY?" posts on Tumblr after each episode would air with no sign of him. This was eventually mashed up with ''Literature/WheresWaldo'', who is called "Wally" in every country but Canada and the U.S. ''Then'', [[spoiler:after Wally's death in "Endgame," Artemis's first words are "Where's Wally?"]] Which is now getting added to the meme.
** Equating the Light (particularly their faceless group shot) with Cartoon Network executives.
** "Touch the Batmobile, and you're fired." "...I hate this family." [[labelnote:explanation]]A meme that cherrypicks several screencaps from [[Recap/YoungJusticeS2E3Alienated "Alienated"]] with a caption that makes it seem like Batman is being comically stern and cold towards his proteges in contrast to the other mentors and their sidekicks. Its even assumed by newcomers that it was spoken in the actual episode (especially since it sounds like something Batman would actually say), even though it wasn't--the line and context of the scene (where Batman sincerely sees off Nightwing, Robin and Batgirl on good terms) is completely different from the meme.[[/labelnote]]
* {{Moe}}: The fans' opinion of Asami "Sam" Koizumi, who is a cute Japanese girl with a tendency to apologize in Japanese.
* MoralEventHorizon:
** The Light technically crossed it before the series even began. The finale reveals that [[spoiler: they kidnapped Speedy and cloned him more than three years ago. The Roy Harper we've been following in the series was a clone and part of their plan, which even he didn't know. Not only that, the real Roy somehow lost an arm (either lost in battle when they caught him, or by amputation after, which would be even worse). They then take the original Roy with them alongside Match when covering their tracks from Cadmus following the events of the episode.]]
** Harm intentionally invokes this, murdering [[spoiler:his little sister, Greta]], the only person he ever loved, so he could wield the Sword of Beowulf. Since only the pure of heart could wield it, Harm decided to make himself [[PureIsNotGood pure evil]]. Even his reason for wanting the sword was so that he could be strong enough to murder members of the Justice League, seemingly just for kicks.
** [[spoiler:Queen Bee is revealed to have killed Garfield Logan's mother purely out of spite, if the Light's overall moment isn't enough to push her over the line. Seeing Beast Boy so broken shows how horrible she truly was.]]
** The Reach crosses theirs by abducting and torturing ''children'' in their attempts to weaponize the meta-gene. In "Cornered" it's confirmed that not all of the abductees survived.
* {{Narm}}: [[Narm/YoungJustice It now has its own page.]]
* OneSceneWonder: Because of the huge cast of DC characters, even those with brief or one-time appearances can make waves in the fandom. These include:
** Jason Todd aka Robin II, who appears as a hologram, having died between seasons. This is only his second animated appearance after the movie ''WesternAnimation/BatmanUnderTheRedHood'', not counting a background joke in ''Teen Titans''.
** Cissie King-Jones aka Arrowette in the Young Justice comics, who appears in season 1 as an unnamed young girl with no lines (her father had a minor speaking role and was named, which is how fans identified her). Since the show is basically an InNameOnly adaptation, fans of the comics appreciated it very much.
** In season 2 there's Stephanie Brown aka Spoiler/Robin IV/Batgirl III, who says a line or two and is only named in the credits. By this time in the comics she'd been DemotedToExtra due to the New 52 reboot as Barbara was Batgirl again (and the only one ever), so her fans took it very well.
** Special mention goes to [[spoiler:Darkseid]] in the season 2 finale. No lines and not even a full minute of screentime, yet the fandom went nuts at the sight of him, with many even citing that scene as a major reason they were angry about the show being cancelled.
* OneTrueThreesome: There a couple of prominent ones. Sometimes, they get folded together into OT4/5.
** There is Dick/Artemis/Wally, due to Artemis and Wally being an OfficialCouple, and fans interpreting Dick and Artemis's interactions as being more than JustFriends.
** Then there's Zatanna/Dick/Barbara. Both Zatanna and Barbara are love interests for Dick in both the series and the tie-in comic, and are implied to be FriendsWithBenefits with him at possibly the same time. And then there's [[http://40.media.tumblr.com/tumblr_mako69cAKd1r2wof4o1_1280.jpg Barbara's suggestive reaction to Zatanna kissing Dick]].

[[folder:Seasons 1 and 2: P-S]]
* PanderingToTheBase: The show's target audience is teenagers. Episode six contains a [[BeachEpisode beach scene]] and the beginnings of a LoveDodecahedron.
* PeripheryDemographic: The target audience may be children 6-14, but the show, particularly the second season, has managed to attract many older viewers due to its tight plotting, serialized plot arcs, and willingness to touch on and openly refer to themes one might expect to find on a pay cable drama. There's even a decent hint of sex, with [[spoiler:Wally and Artemis]] sharing an apartment and her greeting him wearing only a sports jersey. It's much more justified with the CerebusSyndrome of the second season.
* RescuedFromTheScrappyHeap: Many characters are quickly labeled by fans as TheScrappy due to actions that typically have payoffs a few episodes later; which either explain why said character acted that way or they get their comeuppance for it.
** Superman in season two with respect with his relationship with Superboy and his questionable behavior towards him in the first season - if you can get by the lack of actual on screen character development.
** Bizarrely, [[spoiler:Aqualad's ([[TheMole false]]) FaceHeelTurn]] and [[spoiler:Miss Martian's new penchant for MindRape]] are appreciated by some fans as finally giving them some character depth.
** Freakin' ''Lagoon Boy'' got some much-needed depth in issue #23 of the tie-in comic. He expresses a lot of the same desires M'gann had over coming to Earth-- but, unlike her, La'gaan isn't a shapeshifter. So he's still isolated from general society despite living his dream of seeing the surface world. The episode "The Fix" provides him with depth as well, or at least some {{Woobie}} points. Issue #25 also gives him a BigDamnHeroes moment.
** Arsenal establishing himself as TheStrategist and as a ShellShockedVeteran in "The Hunt" is probably the only reason [[spoiler:Nightwing kicking him off the team]] was controversial.
** This incarnation of Cassie Sandsmark/Wonder Girl is this for people who labeled her as a Scrappy in the comics. No doubt she gets better characterization than her comic incarnation.
* RomanticPlotTumor: The Superboy[=/=]Miss Martian relationship for some.
* RonTheDeathEater:
** Some fans seem to give Superman more grief than he really deserves for his reaction to Superboy - though for some it wasn't so much his reaction but rather the lack of character development that went with it that bothers them.
** Lagoon Boy [[RomanticFalseLead for being Miss Martian's rebound guy.]] Noticing a trend?
* RootingForTheEmpire: Everyone rooted for Deathstroke to beat the life out of Lagoon Boy in their fight, to the point where they actually wanted him to get ''killed'' by Slade.
* TheScrappy: Aquagirl is hated by some fans who believe her to have strung Kaldur's feelings along, when she rejected him and started dating Garth instead (despite the fact that her and Garth were paired together in the original comics). It doesn't help that any more possible character development occurred offscreen before her death (during the timeskip between seasons).
* ShippingGoggles: A sect of fans seem to believe Superman and Wonder Woman may be a couple in this show's universe, despite a lack of screen time, characterization and interaction. Must be the fact that Lois Lane was nowhere to be seen before season 3 (minus a cameo in the tie-in comics).
* ShipsThatPassInTheNight: [=WonderBeetle=] gathered a bit of the fandom despite them never interacting on screen.
** Then the tie-in comic reveals that Nightwing chose Wonder Girl to help him recruit Blue Beetle.
*** And according to the Scarab, [[MySensorsIndicateYouWantToTapThat she triggers bio-chemical changes in Jaime.]]
** [[spoiler:Red Arrow and Cheshire]], unless one counts the two times in season one where she flirts with him (and both were for deception). [[spoiler:Come season 2, and they're married with a daughter, although Red Arrow is questionable father material at best (he's consumed with searching for the real Roy Harper). Kind of strange when you realize that Chesire antagonized Red Arrow and the rest of the team, and he acted harshly towards Cheshire's younger sister, Artemis.]]
* SignatureScene: [[spoiler:Wally's death]] is cited by many fans as the most memorable ([[{{Tearjerker}} and saddest]]) scene in the whole series.
* {{Squick}}:
** Miss Martian and Superboy making out while still disguised as brother and sister. Would it have been so hard for Conner to give Megan some sort of warning so she could drop the disguise ''before'' she and Superboy played tonsil hockey? Icicle Jr. has this ''exact'' reaction in-universe.
** Queen Bee creepily splayed out on the bed next to Garfield in the same episode. Knowing that she had him in her thrall certainly didn't help.
* StrangledByTheRedString:
** [[spoiler:Robin and Wonder Girl]] hooking up in the series finale, mostly because ''they're never seen interacting with one another beforehand''.
** Miss Martian and Lagoon Boy is at least justified by the TimeSkip, but from the audience's perspective we go from "Miss Martian and Superboy in a successful relationship" to "Miss Martian locking lips with someone we've never seen before".
[[/folder]]

[[folder:Seasons 1 and 2: T-Z]]
* TheyChangedItNowItSucks:
** In spite of the fact that the series itself is ''not'' an adaptation of the ''Young Justice'' comics, quite a few fans of the comics aren't happy with the creative team's decision to alter the identities of characters from the comics of the same name. ([[http://www.s8.org/gargoyles/askgreg/search.php?rid=866 Weisman's take on the issue]].)
** Some fans' complaints are incredibly petty, such as people complaining that Superboy is [[FelonyMisdemeanor wearing cargo pants instead of jeans]].
** Creator/BrentSpiner voicing ComicBook/TheJoker is taking hits for generally not being very good, for not being Creator/MarkHamill, for not being Creator/JohnDiMaggio, etc.
** In the first season, Superman's characterization and behavior regarding Superboy was a sticking point for many viewers.
** The Season 2 TimeSkip gets a lot of this for [[NothingIsTheSameAnymore changing almost everything]]. While it explores more mature themes, the second season also put many of the older members of The Team out of focus for a long time while introducing characters that hardly have any personalities aside from a few aspects.
** Some of the AdaptationalHeroism can feel a bit jarring. This is especially true of Cheshire, to those who know her as the genocidal psychopath from the comics. Though in Cheshire's case it is a bit closer to how she originally was in the comics (see OlderThanTheyThink.)
** Wally West ''not'' becoming the third Flash is this for his fans. It doesn't help that [[spoiler:they had to pull a lot of stuff for him to die in the last episode]], and that, with him coming out of retirement during the large crisis, it was almost point for point like how he became the Flash in the comics. What makes it worse is that this was the last people saw of the classic Wally West for ''years'' until ''ComicBook/DCRebirth''.
** Lagoon Boy. In the comics, he was pretty cool, despite not being as characterized as the other heroes. He was even pretty ripped, to the point where his puffer form reaches [[Franchise/DragonBall Roshi-On-Max-Mode]] levels of ripped. Here, he’s less characterized and a PlotDevice in Superboy and Miss Martian's story and is a {{Jerkass}} to almost everyone, especially Superboy. It reaches the point where he even disrespected his ex-girlfriend M'gann once when immediately threw an accusation into her face that she was still in love with Conner after she breaks up with him (La'gaan). Also, he’s lacking the muscular features that his comic counterpart had, instead being a bit lanky and being extremely fat in his puffer form.
* TheyWastedAPerfectlyGoodCharacter: As a consequence of having LoadsAndLoadsOfCharacters and limited screentime, more than a few of the cast end up getting the short end of the stick in terms of utilisation and characterisation in the eyes of the fans.
** Ocean-Master. He was the least featured member out of of the original seven members of "The Light", and whilst it is known that he is actually Aquaman's brother Prince Orm by DC fans and from reading the tie-in comic, those who are only following the show will have no idea that Orm and Ocean-Master are one and the same. In between seasons 1 and 2, he has been "disgraced" and replaced by Black Manta, who was already featured in an episode. [[spoiler:He returns in Season 3, only to be unceremoniously killed off by Lady Shiva before he even does anything, all because he attempted to murder the heroes' children in revenge, [[EvenEvilHasStandards something even the Light frowned upon for the sake of making sure the heroes don't become too extreme]].]]
** ComicBook/BlackAdam and the [[MadScientist Ultra-Humanite]] both got this treatment in their first and only appearances (not counting the tie-in comics). In the show, they were both reduced to TheVoiceless DumbMuscle to Count Vertigo of all people (an AdaptationalBadass, but partly just because he's bossing around guys like these two), and are defeated relatively easily. In the comics, both are A-list {{Genius Bruiser}}s and {{Visionary Villain}}s who can challenge entire teams of heroes by themselves, and neither would look out-of-place amongst the leaders of the Light. [[spoiler:Ultra-Humanite ends up becoming one of the Light's newest members. Black Adam, meanwhile, only gets a mention of conquering planets offscreen for the Light.]]
** The Justice League as a whole. Many of the members barely get any speaking lines (and some like Hawkman and Hawkwoman never speak at all, at least not at first), and generally the League is shown to be fairly incompetent at their jobs, requiring the Team to do most of the actual work in defeating the Light. In fact, it's often when the Team ignores the League's orders to stay out of things that saves the day. It seems like the world would be a better place if the League placed the Team in charge of things.
** Robin III (Tim Drake) has gotten this reaction from some because despite having quite a few appearances, he's rarely given any depth and characterization besides being yet another Robin leading a squad. Most of the time he doesn't even speak unlike Robin I/Nightwing who has plenty of lines; Batgirl also has more lines. ''Young Justice'' is also only the third time Tim has appeared in a DC cartoon after ''[[WesternAnimation/BatmanTheAnimatedSeries The New Batman Adventures]]'', ''WesternAnimation/BatmanMysteryOfTheBatwoman'' and ''WesternAnimation/BatmanBeyondReturnOfTheJoker'', unlike Dick who's featured in many more shows - thus all the more disappointing for some. Also consider that Tim was the Robin of the ''Young Justice'' comic, not Dick.
** The Runaways. They were set up as a potential anti-heroic rival for the Team, only for Static to join the Team and the others besides Arsenal to quit. One of them, El Dorado, escapes this when he joins the Outsiders in season 3, but the rest are still no shows. (Their quitting isn't even shown on screen.)
** Bane. He's shown to be every bit as smart as members of The Light, but the episode he appears in has already suffering from a case of EvilerThanThou / TheWorfEffect at the hands of Lord Kobra, and the next he appears, he's just relegated to the role of a generic thug. Fixed somewhat in his return in season 3, where he works with Deathstroke and combats Batman when he and his squad infiltrate Santa Prisca.
** Klarion is a powerful and entertaining villain, but by season two he gets no speaking roles and appears only to shuttle Vandal Savage around. He finally gets a major appearance again in season 3, even speaking once more, due to his role in Project Rutabaga. But alas, Zatanna and the Outsiders trap him in Doctor Fate's tower and he is reduced again to silent cameos ([[WordOfGod Greg having confirmed]] he did escape the tower later on).
** Wally West himself, one of the most popular characters in DC comics, founding member of the Teen Titans, longtime member of the Justice League and the definitive Flash for an entire generation, is DemotedToExtra in Season 2, [[spoiler: and then [[NotHisSled killed off before he can even become the Flash in the very same way Barry originally died]]]].
* TheyWastedAPerfectlyGoodPlot: Not taking the time to explore the subplot of Superman and Superboy finally developing an actual relationship (season two expects the viewer to just accept that they now see each other as brothers) may count. The comics that were made alongside the show ''do'' show some of the process... but the comics end long before Supes gets out of the "StalkerWithoutACrush" stage of {{Superdickery}}.
* UglyCute:
** The little G-gnomes fall under this.
** Megan's [[spoiler: true form falls under this. Despite being a 'hideous' White Martian?]] You ''still'' want to hug and comfort her due to her genuine sweet personality. Doesn't hurt that she's a full-on {{Woobie}}.
%%* UnfortunateImplications: %%Unfortunate Implications require citations.%% M'Gann's MindRape of Conner between Season 1 and 2, which is the catalyst for them breaking up. Conner is rightfully angry whilst M'Gann seems dismissive of the fact that she essentially forced her presence and mind on him to manipulate him. Take the mind part out of it, and well... Aside from whether or not any one else knows the reason for their break-up, the fact that M'Gann doesn't recognise her abusive behaviour nor completely apologises for it, and that Conner still pines after her can still come across as disturbing.
* UnintentionallyUnsympathetic: After all the whining and bitching he did throughout the show not everyone wanted to comfort Roy "Speedy/Red Arrow" Harper when the Jerkass finally learned he was a clone and came to doubt the validity of his existence.
* WhatAnIdiot:
** Arsenal randomly decides to go against orders, [[spoiler:and ruins their cover with an explosion that did little to no actual damage, just to spite Luthor.]]
** Nightwing for thinking that putting him on that team was a smart idea to begin with despite Arsenal's clear mental instability.
*** Especially since blowing things up very loudly is basically all he's done since waking up! Seriously, in a stealth situation, what could he do that Robin wouldn't have done better (being, you know, a member of the Batfamily and all?)? Hell, if someone asked him to take his damn hand out of his pocket (which they really should've, since obviously some people weren't happy about the Reach), they would've been royally screwed.
*** Later, in "The Hunt", he decides that the perfect time to kick Arsenal off the team is ''right after'' he saved them all from the Reach, right in front of the Runaways. Honestly, he deserved to [[spoiler: lose him and four potential members of the team.]] He also chooses to make this declaration while still behind enemy lines, which even he admits isn't the right place for a discussion on the matter.
** Nightwing faking Artemis's death and not telling the team. While it may have been necessary on some level to ensure Aqualad's cover, not telling M'gann in particular was utter insanity, as she's a telepath who has been getting way too MindRape-y with her powers of late. Best case scenario, she finds out by reading Aqualad's mind. Worst case, she psy-blasts him and turns him into a vegetable. Which is exactly what happened. Even Nightwing himself verbally admits not letting M'gann in on the plan was a fuck-up on his part.
* WhatDoYouMeanItsForKids: The original series on Creator/CartoonNetwork was guilty of this. The show is rife with innuendo (including a ''joke about {{twincest}}''), many references to and depictions of murder, and doesn't shy away from the severe mental strain that is put on ChildSoldiers.
** One of the protagonists' favorite tactic is MindRape. And it is played out for maximum shock value.
** The subplot in "Beneath" heavily implies that the mother of one of [[ComicBook/BlueBeetle Jaime Reyes]]'s friends is being [[DomesticAbuse physically abused by her boyfriend]]. The same episode also reveals that Queen Bee is essentially running a [[HumanTrafficking child-trafficking ring]], where innocent teenagers are kidnapped and sold to evil aliens who use them for horrific biological experimentation.
* TheWoobie: [[Woobie/YoungJustice It now has its own page]].
[[/folder]]

[[folder:Season 3]]
* AcceptablePoliticalTargets: Season 3's depiction of Lex Luthor is seen by many to a TakeThat against {{Obstructive Bureaucrat}}s and self-serving politicians.
* ArcFatigue: By the conclusion of season 3, very little progress seems to be made on the overall series arc. [[spoiler: Luthor loses his position as Secretary-General, but [[KarmaHoudini remains free]] and retains his position in the Light. Granny is being punished by Darkseid as a scapegoat, but will undoubtedly be free to continue as before. And despite everything that happened, the alliance between Darkseid and the Light remains firmly intact. While there's talk of a great galactic war coming, it's kept so [[VaguenessIsComing vague]] that it's near-impossible to guess what the threat could be.]] This entire season can be considered just setup for the actual central conflict that may or may not finally happen in Season 4. Either way, the arc of the series is moving a lot more slowly than many had expected. Most fans took as ''given'' after the Season 2 stinger that Apokolips would invade Earth in Season 3, which [[spoiler: doesn't happen. The Earth is arguably never under direct threat in Season 3, unless you count the minutes it appeared Granny had successfully taken control of most of the heroes.]]
** This can also apply to the [[KudzuPlot many subplots]] started or continued in Season 3. Even more so than previous seasons, the writers clearly didn't write the season with any aim to be conclusive overall. Plot threads are laid all across the season that are never touched upon again but are clearly meant to be continued at some point. Anything involving [[spoiler:Jason Todd and Ra's al Ghul, Cheshire, or the potential for giving non-metahumans the metagene]] is left unresolved.
* AlternateCharacterInterpretation: [[AlternativeCharacterInterpretation/YoungJustice It now has its own page.]]
* AuthorsSavingThrow:
** A complaint some had about the LoadsAndLoadsOfCharacters that were introduced in ''Invasion'', was that many of them were dumped in rather haphazardly, especially prominent with the second iteration of the Team. It introduced seven, later up to nine, new Team members but of them only Blue Beetle and Impulse got a lot of focus, giving the impression that the others were kind of just "there" in the midst of the large cast (it didn't help that ExecutiveMeddling cut ''Invasion'' to 20 episodes from the planned 26). Now, while ''Outsiders'' also introduces many characters in the first few episodes, many of them are cameos until later, while the three big new additions to the main cast in the early episodes -- [[AscendedExtra Black Lightning]], Geo-Force and Halo, are given proper development before focusing on new and other cast members. Same could be said for later recruits Forager and Cyborg, both of whom are very well-developed after their first appearance.
** [[spoiler: Terra being TheMole]] is made clear at the end of her debut episode, showing that the writers are aware that this plot point is [[ItWasHisSled already well-known]] as opposed to kicking around it.
*** The irony with the above is [[spoiler: most, if not all, of the heroes are ALSO aware from the very beginning that Terra is TheMole compared to most versions where no matter how explicitly evil she is, they're completely unaware and blindsided. The changes allow the viewers to get a look into Terra's mindset and understand why she is willing to spy for Slade (and why she ultimately turns on him when she realizes the heroes truly care about her) and also allows the heroes to seem far more intelligent.]]
** It was a very common complaint among fans that The Light in the first two seasons often bordered on, or were, {{Invincible Villain}}s, with even the hardest fought victories ultimately resulting in them gaining some kind of benefit that negated whatever the loss they incurred. The second half of the season has [[spoiler: Zatanna cleverly trap Klarion in Fate's Tower (though he escaped off-screen by the last episodes of the season, including the season 3 finale, as Greg Weisman confirmed he eventually found a way out)]] and in the next episode has [[spoiler: the Outsiders outmaneuver Lex Luthor, resulting in him being humiliated on live television and leaves him raging, as well as establishing that Luthor does, in fact, share some of his comic counterpart's pettiness and greed, and despite previous statements to the contrary, isn't above getting revenge when someone actually manages to hurt him. This continues when Superboy, Superman, Cyborg, and Black Lightning also force him to resign from the position of Secretary-General due to evidence found via Terra's earpiece, although possibly due to JokerImmunity, he isn't removed from the Light because of this.]]
** After the controversial [[spoiler:Harper/Violet kiss]] as the show's first romantic LGBT depiction (which was criticized for feeding into stereotypes about attraction between women), "Quiet Conversations" would delve into Harper's background to provide context for her actions, give Violet time to herself to properly address her own identity issues, and provide positive LGBT depiction with the reveal that [[spoiler:Kaldur and Wyynde are a couple]] (helped that Kaldur being LGBT was something originally intended but was [[ExecutiveMeddling meddled by Cartoon Network in the show's initial run]]) as well as having the two explicitly showing affection to each other onscreen.
** Many were upset at the end of season 2 with M'gann and Connor getting back together [[DoubleStandardAbuseFemaleOnMale while the issue of her brainwashing him being remained unresolved.]] The prequel comic for ''Outsiders'' has her feeling guilty over it and asks him for forgiveness.
* CatharsisFactor:
** Seeing Luthor get taken down a peg by The Outsiders can be satisfying after getting away with a VillainWithGoodPublicity status in the first two seasons. [[spoiler:The finale with his corruption being exposed has him being forced to resign from his post as UN Secretary General only sweetens the deal]].
** It's treated in-Universe as his MoralEventHorizon, but [[spoiler:Brion executing his vile uncle Baron Bedlam by suffocating him to death is still satisfying to watch, especially considering what Bedlam did to ruin Brion's life at the start of the season.]]
* CharacterRerailment:
** Lex Luthor's portrayal in Season 3 is more in line with his other counterparts, coming across as being a somewhat petty and vindictive man in his P.R. war with the Outsiders.
** Similarly, Batman in season 3 becomes more in line with his more mission obsessed depiction from the comics than in earlier seasons.
* ContinuityLockout: The show has always required you to be fairly well-versed in the DCU to fully grasp much of it, but this season takes it UpToEleven, especially now that the show has moved to a service that's aimed primarily at existing comics fans. Season 3 really ups the ComicBook/NewGods lore, with (so far) the appearance of the Female Furies, the Source Wall, Metron, Bugg, and other elements that are mostly exclusive to that part of the DCU. The New Gods are quite popular with both comic fans and critics, but barring [[BigBad Darkseid]], are extremely obscure with [[MainstreamObscurity general audiences]]. They have appeared in prior adaptations (most prominently the DCAU), but they rarely dug too deeply into that part of the universe. They've also never had an adaptation dedicated solely to them.[[note]] There is a movie in development but it is still a few years off. [[/note]] ''Young Justice'' seems interested in exploring and developing it much further than done in prior adaptations and isn't focused entirely on Darkseid.
* CrossesTheLineTwice: [[spoiler:Gar’s visions in [[Recap/YoungJusticeS3E12NightmareMonkeys "Nightmare Monkeys"]]. ''Especially'' the ''WesternAnimation/TeenTitansGo'' parody of the Doom Patrol, where it's about Beast Boy begging them not to go on the mission that killed them during the TimeSkip and them insisting that they have to while cheerfully singing about how they're going to die. ''Yeah''.]]
* EpilepticTrees:
** That Terra [[spoiler:is, or at least will become, a triple agent, since [[ItWasHisSled her betraying the heroes is a well-known plot]] that has already been done in the comics and the [[WesternAnimation/TeenTitans animated]], [[WesternAnimation/TeenTitansGo adaptations]] [[WesternAnimation/TeenTitansTheJudasContract that followed]], and that it wouldn't be above the ''Young Justice'' writers to do something fresh with a plot twist.]][[note]][[spoiler:Which while she still is TheMole, she indeed [[NotHisSled chooses to be a hero instead of betray the heroes]].]][[/note]]
** In Gar's visions in "Nightmare Monkeys", he sees all of the heroes that died during the show and they all get shot... [[HesJustHiding except for Kid Flash/Wally]].
** That Hal is going to [[FaceHeelTurn turn]] into [[DemonicPossession Parallax]] because he looks [[RapidAging visibly aged]] despite looking normal for a man in his thirties in previous seasons (and only two years have passed in-universe since Season 2), especially since this was what happened to his body due to Parallax subtly influencing him before actually possessing in the source material. That, or [[MemeticMutation he got stripes from working with Guy Gardner for that past two years]].
*** In addition, this will lead to another Green Lantern character appearing later in the show (most popularly guessed to be Kyle Rayner, a character that fans had been hoping would eventually appear), due to the show's frequent use of [[ChekhovsGunman Chekhov's Gunmen]], especially in this season where we've been introduced to numerous {{Legacy Character}}s that will likely later become superheroes in their own merit in line with the comics. Also, the Team has featured members from just about every part of the DC Universe, with Green Lantern being the biggest one that hasn't had any representation in any version of the team, as every Green Lantern introduced so far has been an adult. Kyle Rayner at the time of his introduction was a college student, making him arguably the easiest to fit onto The Team (though there are newer human Green Lanterns introduced since Kyle (Jessica Cruz and Simon Baz), but they were all older than Kyle was when they gained their rings).
** Helga Jace's behavior has been suspect, especially in regards to how she's studying Halo and Cyborg. It's enough to make fans assume she's secretly evil, either working for the Light or toward her own selfish goals. Her behavior has been questionable enough that quite a few fans suspect that [[spoiler: her (unverified) claim of Violet dying is a lie.]] The fact she still [[spoiler: doesn't tell them, or even hint at, Violet dying after she runs away is certainly odd, if still potentially explainable.]] This turned out to be [[spoiler: mostly correct.]]
** Gar's new profound attitude and assertiveness in the later half of the season, along with his campaign for a public teenage superhero team, have garnered concern from some fans, especially when speculating [[BrainwashedAndCrazy how deep the subliminal brainwashing from the Goode Googles goes down.]]
* FranchiseOriginalSin: Most of the more ''discussed'' aspects of Season 3 aren't new:
** The voice acting. As noted prominently in the trivia section, Young Justice has always had to employ clever audio tricks or heavily reuse voice actors (or not have characters speak at all), because many episodes feature so many different characters that bringing in a different voice actor for each is not practical from a budget standpoint. This is usually mitigated by the talent of the voice cast (Bugg has [[Creator/JasonSpisak the same voice actor]] as Wally, but you'd be hardpressed to mix them up), there being in-universe reasons for characters having similar voices ([[Creator/NolanNorth Superboy]] is a clone of Superman; [[Creator/DanicaMcKellar M'gann]] based herself after Marie Logan) as well as the fact that most of the ''main'' characters are all voiced by different voice actors, but with each actor doing several smaller roles; but each season adds more and more characters meaning more and more roles to voice in addition to the ones that already exist, so some of the voice actors end up voicing many, many roles. The issues some have with the voice acting for child characters, such as Amistad (voiced by Creator/KharyPayton) and Lian (voiced by Creator/ZehraFazal), is, however, new, simply because characters of their age weren't present in prior seasons, and can probably be explained by the fact that they are young children being voiced by adults.
** Character Relationships. The show has always been weird about pairing characters, developing relationships, and teasing others, with many of the most prominent relationships being created whole cloth by the show itself, and many other relationships not getting the proper development or setup. Conner/M'gann and Wally/Artemis, as can be shown by entries covering the earlier two seasons, had some detractors because they had no basis in the original comics. Cassie/Tim are a rather infamous example of the show suddenly pairing characters with little to no build-up, as the two had never even been shown speaking to each other before they were stated to have gotten together, and each having more prominent love interests (or at least Tim does, Cassie's is taken) than each other in the comics (though they ''have'' dated in the comics, it's just not the relationship most fans of either character like). Thus, the sudden ShipTease of Will/Artemis isn't unique, rather it just involves two characters that most fans particularly don't want to see become romantically involved with each other (as opposed to just apathy), whether it be the NoYay of in-laws becoming romantically involved while the spouse is still around (and may not have left of her own [[DaddyHadAGoodReasonforAbandoningYou free will]]) or the fact both characters are part of other pairings that many prefer. Though to the show’s credit, ultimately Will and Artemis decide that there were NoSparks between them and that they had both let Paula’s desire for Lian to grow up in a NuclearFamily get into their heads. They decide that they don’t have to be in a relationship to raise Lian together.
** Representation. The show has always been invested in having a racially diverse cast, with characters such as Artemis getting a RaceLift, Kaldur being created to take the role of Aqualad, several Hispanic characters such as Jamie and Eduardo Jr. having prominent roles, etc. However, ''Young Justice'', like most popular entertainment, has always skirted around religion, with none of the characters ever referencing it in either belief or disbelief. This presents a problem with Violet, the first character in the show that faith is ever presented as an issue for. Violet's appearance (dark skin, headscarf, dresses conservatively) fits the stereotype of what many assume a Muslim woman ''looks'' like, but they explicitly state that they are ''not'' a Muslim in practice or belief. It's obvious why the creators would want to specifically represent Muslims (as opposed to other religions) given topical events, but Violet was probably never a good fit given their new origin of being [[spoiler: the spirit of a Motherbox, an extraterrestrial pseudo-mystical object/being that has no investment in any human religion]].
* HarsherInHindsight:
** Every interaction and all the advice [[spoiler:Dr. Helga]] gave to the young heroes and every scene of hers with Black Lightning are this [[spoiler:given she was a heartless maniac who used them all]].
** Back in "Disordered", Dick admitted he was now disturbed by how Batman is willing to sacrifice everything to complete his mission and that he didn't want the same. Now he's fallen into the same supposed idealism as him, working with his Anti-Light and seemingly showing/having no remorse for it.
** Wally's [[WhatTheHellHero call out]] of Dick applies just as well [[HistoryRepeats in Season 3]] as it did in Season 2, making it all the harsher because Dick doesn't seem to have learned anything (also potentially because what Dick had done before enabled the captures of Black Manta and Brain, and disabled the Light's partnership with the Reach). The Anti-Light was a complex, highly-sensitive operation that is [[spoiler: exposed]] as a result of circumstances that [[DidntSeeThatComing couldn't be foreseen]] by anyone. But, unlike with the undercover op, the situation can't be salvaged by the individuals involved, and it's outside of their power to stop it all from falling apart after [[spoiler: Jefferson forces them to admit it in front of half a dozen other people, irrevocably breaking the [[BrokenMasquerade masquerade]].]] The fact said operation involves two of the three major players as the one that was originally being called out only makes it more applicable. While Nightwing's original secrecy didn't give him too much consequences in the end once it was all revealed (he only chose to leave the Team because Wally died, whereas Artemis and Kaldur retained their positions on the Team), this time around, [[spoiler:while they are still members of their respective groups, Kaldur and Wonder Woman hand the Justice League to Black Lightning for their parts in the scheme, and M'gann steps down as leader of the Team in favor of (according to the audio play at ''[=FanDome=]'') Artemis taking over]]. On the bright side, at least it wasn't Dick's idea this time.
** Early in Season 3, Artemis reminds the others that being a metahuman doesn't automatically mean Violet and Brion need to become heroes, and that she and Dick [[BadassNormal aren't metahumans]], but still heroes, with the implication being they are no less capable than any metahuman regardless. This can sure seem worse after [[spoiler: Dick ''not'' being a metahuman is why the X-Pit effects him far worse than Jefferson. And then both she and Dick are taken control of by the Anti-Life Equation, which partly relies on the X-Pit to work and Granny states the Equation also has a far worse effect on the minds of non-metahumans...]]
* HilariousInHindsight:
** Season 3 reveals that [[spoiler: Darkseid once tried to invade Earth in the distant past and was met by an army of humans with bows and arrows working with superhuman beings]]. This lines up fairly well with parts of the ''[[Film/JusticeLeague2017 Justice League]]'' film and even better with the [[Film/ZackSnydersJusticeLeague Zack Snyder cut]]. It's all the more amusing if Greg Weisman and Brandon Vietti already planned this out years before, since ''Young Justice'' predates the Franchise/DCExtendedUniverse that ''Justice League'' is part of.
** In the [[WesternAnimation/TeenTitans 2003 Teen Titans animated series]], Creator/AshleyJohnson played Terra. Now [[VideoGame/TheLastOfUs the Joel to her Ellie]], Creator/TroyBaker, plays her brother Brion in the Outsider series. Meanwhile, Terra in Outsiders is played by Creator/TaraStrong, who as Raven in ''WesternAnimation/TeenTitans'' and ''WesternAnimation/TeenTitansGo'', was respectively the most suspicious of Terra, and [[LoveTriangle her rival for Beast Boy's affection]].
** "Evolution" revealed that Vandal Savage was once a god-king of ancient Babylonia and saved it from an otherworldly invasion. The episode came out about a month after the videogame ''VideoGame/FateGrandOrder'' released its ''Babylonia'' story chapter [[note]](about a month after the English version, that is; it was originally released in Japan years earlier)[[/note]] which has a broadly similar premise, and this leads to some strange ''deja vu'' if you're a fan of both. Vandal goes by the name Marduk in Babylonia and while the game's god-king is Gilgamesh, the god Marduk still plays a role in its story. The goddess Ishtar appears in both and she is Vandal's daughter here. And the kicker is that Doctor '' Fate'' is given an unexpected origin story connection to Vandal, as Nabu the original Fate becomes Vandal's son. Similar to the ''Justice League'' movie above, while the game predates the release of Season 3, the cartoon as a whole and thus the planning for it predates the game by several years.
** Artemis has a major argument with her mother over her continuing super heroics in “Illusion of Control”, with Paula pushing her hard to retire permanently. Almost immediately following that episode, Artemis falls OutOfFocus and isn't seen participating in any on-screen missions until “Terminus”.
** [[https://www.behindthevoiceactors.com/characters/Batman/Lady-Shiva/ This page]] has a comment from 2014 suggesting that Gwendoline Yeo voice Lady Shiva. Cut to 5 years later, and she ends up voicing her.
** On Ask Greg during the show's original run, when asked if Creator/LauraBailey or Creator/TroyBaker would be joining the cast, Greg answered that he had no idea who they were. Come Season 3, where Troy Baker is a main cast member.
* IAmNotShazam: Fans assumed that Nightwing's team in the first half of season 3 were The Outsiders despite them not using the name. The name is actually used for Beast Boy's team in the second half of season 3. To be fair, the confusion is understandable -- they were clearly based on the Outsiders from the comics with team members distilled from various eras, have had brief a MythologyGag where they were referred to as operating on the outside (emphasis on "outside"), and thematically they ''are'' outsiders in the first half for not being legally sanctioned. It was likely an IntentionalAudienceReaction, if anything. The fact Nightwing's team bore a closer resemblance to the comic team in terms of team make-up (though still heavily divergent) and operation, while Beast Boy's bears a closer resemblance to the Teen Titans (right done to them operating out of a tower) also makes the misconception understandable and is likely more proof that it was intentional.
* IdiotPlot: It's been pointed out that the deal shown in “Private Security” between Nabu and Zatanna is actually rather silly and counterproductive. Giving Zatanna and Zatara just one hour a ''year'' together comes across as excessively [[CruelMercy cruel]] and stingy, but more importantly--for Nabu, at least--being that callous is bad for him in the long run. When Zatara takes off the helmet, it's clear from his aging and worn appearance that being constantly possessed by Nabu is wearing down his body far faster than would be natural, meaning Nabu is actually lessening the length of time he can keep using his current (ideal) host by requiring he always wear the helmet. And since he's being so harsh, when Zatara's form inevitably gives out, no one in their right mind is going to willingly put on the helmet again, knowing Nabu likely won't ever let them take it off--and probably wouldn't even be given the chance, because Zatanna would reasonably proceed to either [[YouKilledMyFather destroy the thing]] or dispose of it [[FateWorseThanDeath somewhere no one could ever find it]]. It's rather [[DidntThinkThisThrough short-sighted thinking]] for an immortal spirit.
* ItWasHisSled:
** A red-hooded ninja working for Ra's al Ghul being [[spoiler: Jason Todd, the presumed to be dead Robin II.]]
** Even casual viewers probably won't be surprised to learn [[spoiler: Terra is secretly working for Deathstroke]].
** Believe it or not, the existence of [[spoiler: the Anti-Light]] was originally a [[TwistEnding twist]]. Even Wiki/ThisVeryWiki never bothered hiding it.
* ItsTheSameSoItSucks: [[spoiler: Terra being revealed to be a traitor and a spy in "True Heroes", since it had already been done in the comics in the '80s and their [[WesternAnimation/TeenTitans animated]] [[WesternAnimation/TeenTitansTheJudasContract adaptations]], although [[EpilepticTrees fans hope that she's some sort of triple agent]]. This became subverted when she ended up BecomingTheMask to a far greater extent than in previous depictions, undergoing a HeelFaceTurn, turning against Deathstroke for good and [[SparedByTheAdaptation ultimately surviving]] the ordeal.]]
* MemeticMutation:
** After "Private Security" was streamed, many viewers want to see a spin-off series with all the Harpers working in Bowhunter Security, being assisted by Dick at times. This gained more support after Greg posted someone's tweet in his Twitter account, being supportive of the idea.
*** Coming off that same episode, there's Will Harper's love for his clipboard with fans joking the clipboard has usurped Speedy's yellow hat in Will's heart.
*** Viewers call Dick in a Bowhunter Security guard uniform, "Officer Dick Grayson".
** "[[WesternAnimation/SouthPark Oh my God]], [[TheyKilledKennyAgain they killed Halo]]!" Halo's [[DeathIsCheap multiple gruesome deaths and resurrections]] throughout Season 3 have been met with both criticism and amusement by viewers, even though the show itself hasn't played her series of fatal injuries for BlackComedy (yet).
** "Tim Drake said "Let's go, lesbians!"". Tim leading a squad of superheroines who all happen to have a lot of HoYay lead some fans of adopting famous Billy Eichner line for him.
** Referring to Forager as "Fred Bugg With Two G's" grew popular quite quickly after he spent an entire episode [[LiteralMinded thinking that the whole phrase was his new name.]]
** "Have you read the part about the bear?". Olympia, one of Vandal Savage's daughters, is senile and constantly obsesses over that part of the book that she wrote about him. This annoys her sister and ultimately proves to be her undoing since it draws Vandal's attention to her mental state.
* MemeticLoser: Again, Halo due to her repeated DeathIsCheap moments, and Static due to his less than successful love life and his vocal whining about needing to get a girlfriend.
* SugarWiki/MostWonderfulSound: A lot of fans find the bassy thrums let off by Mother/Fatherboxes and Overlord whenever they open a boom tube to be quite satisfying.
* MoralEventHorizon:
** From ''Outsiders'', there's [[spoiler: Baron [=DeLamb=]]] the leader of Bedlam, a metahuman trafficking ring that experiments on children and teenagers to activate their meta-genes. The process has an incredibly high mortality rate, with the best-case scenario being that the survivors are sold off-world as mind-controlled living weapons. Two stand out moments of [[spoiler:[=DeLamb=]]] crossing the line are either when he experimented on and sold his own [[spoiler: niece]] or assassinated his [[spoiler:sister and brother-in-law.]]
** [[spoiler:Helga crossed it by either deciding to experiment on Tara, manipulating Brion and Jefferson or orchestrating Violet's downfall, resulting in her and Brion's emotional suffering and ultimately on Darkseid getting the Anti-Life Equation.]]
** Granny Goodness is nasty as typical for her character, but it's not until "Terminus" she really shows ''why'' she's one of Darkseid's most feared lieutenants: [[spoiler:using Violet, the living Anti-Life Equation, Granny attempts to plunge the entire galaxy into an X-Pit, which will result in the tortuous death of countless billions, only sparing the Meta population to use as slaves.]]
* {{Narm}}: [[Narm/YoungJustice It now has its own page.]]
* RescuedFromTheScrappyHeap: Roy “Will” Harper suffered from a bad case of UnintentionallyUnsympathetic due to an abrasive attitude, which even preceded his CloningBlues, abandoning his (pregnant) wife, developing a implied drug addiction, and then lashing out at his friends and family when they staged an intervention. So ''many'' fans were pleasantly surprised when he reappeared at the start of Season 3 as a [[CharacterDevelopment devoted]], [[LighterAndSofter lighthearted]], mostly-retired-from-heroics single father focused on running his own small business and doing his best to raise his young daughter after his wife's [[AmbiguousSituation mysterious]] departure. His [[ADayInTheLimelight day in the limelight]] episode is one of the better-regarded episodes of the first half for being a BreatherEpisode after a three-part DarkerAndEdgier season premiere. It helps greatly that he is based off a version of Roy Harper whose absence in the comics for over a decade now is something a [[WebVideo/AtopTheFourthWall vocal]] group of fans are still ''very'' bitter about, giving fans starved for any content relating to that character something to enjoy. Also, the existence of both him and the original Roy Harper means that fans of either (or [[TakeAThirdOption both]]) versions of the character can get what they want. Fans of the more mature, single-father Red Arrow Roy Harper (and his daughter, Lian) have 'Will', while fans of the newer, edgier Arsenal Roy Harper have the physically-younger, brasher, original Roy Harper. The only new aspects of 'Will' Harper a majority of fans don't seem to appreciate are his [[ShipTease heavily-suggested]] romantic interest in his [[NoYay sister-in-law]] and that his mostly-retired status means, like [[DemotedToExtra Wally]] in Season 2, he has [[OutOfFocus little-to-no relevance]] to the overarching plot of the season, with his appearances outside of his limelight episode being mostly a side-benefit of Artemis and Violet (and later, Tara) living in his house, and once Violet and Tara move out, he disappears almost entirely for the second half of the season.
* SpiritualAdaptation: ''Outsiders'' is the closest thing to an ''ComicBook/XMen'' animated series we've had in a very long time. Substitute "mutant" with "metahuman", and it's a very easy comparison to make, and some would say that ''Outsiders'' have done the ''X-Men'' concept ''better'' than the recent stories. ''Outsiders'' focuses on the discrimination and weaponization of {{Differently Powered Individual}}s via metahuman trafficking, a criminal enterprise that's plagued the world. The main characters are heroic outcasts, fighting the good fight when the world is actively pushing against them to do so, and integrates real-world subtext in with the storyline by tackling social issues in a way that isn't intrusive or at the expense of the plot. One of the things it does better is how the general public reacts -- many civilians support the heroes, and they gain more support over time. The metahumans aren't treated with universal hatred like the mutants often are, and there's more nuance than many ''X-Men'' stories had while also avoiding potential questions that comes in dealing with FantasticRacism for one superpowered race in a setting where many different origins exist; one of the most commonly asked questions by the fans of Marvel is "why does everyone hate mutants, but give all the ''other'' superpowered beings a pass?". To that end, it's done very well.
* TaintedByThePreview: While the overall reception to ''Young Justice: Outsiders'' is '''very''' positive, there's a little bit of this.
** The animation being apparently below previous quality in the "Bedlam" teaser. Many have taken notice, and worry that budget is a problem. Though given the [[AnimationBump reversal]] in the SDCC trailer, it's speculated that it hasn't been properly completed yet.
** There's also the slight ArtShift into making the style resemble the ''WesternAnimation/DCAnimatedMovieUniverse'', itself having its detractors due to the ComicBook/New52 influences[[note]]Phil Bourassa is the character designer for both this series and the New 52 movies[[/note]]. Some have raised issue with it for not sticking to the classic style of the first two seasons.
** A number of people expressed their displeasure with Barbara returning as Oracle and not Batgirl. As she was OutOfFocus in ''Invasion'', they were hoping she would get more here instead of jumping straight into the Oracle persona. Some are happy if only because it leaves the door open for fan-favorite [[ComicBook/Batgirl2000 Cassandra Cain]] to join under the name of Batgirl.
** Nearly all the fans have been consistently irritated that in all the 2018 trailers, there was still no sign of Miss Martian, Aqualad and Arsenal. At least Aqualad was revealed close to the release, revealed to be the new Aquaman, but it was a long time coming.
* TheyChangedItNowItSucks: Season 3 has gotten this reaction from certain fans in regards to both the new character designs and in part because of the ''[[ArtEvolution slight]]'' shift in the animation style compared to the prior two seasons. Both of those aspects end up making the show look much closer to the ''WesternAnimation/DCAnimatedMovieUniverse'' with certain characters being redesigned to look almost identical to their counterparts in that continuity, which for those who aren't especially fond of those films, isn't helped by them taking a large amount of inspiration from the ''ComicBook/New52'', whilst many characters (in particular the Justice League) were largely based on their counterparts from more classic comic eras (like the ''ComicBook/PostCrisis'' era) in the prior seasons.
* TheyWastedAPerfectlyGoodCharacter: There has been some grievance over the Team being DemotedToExtra, despite them having been the main focus and driving force of the series beforehand. Instead, the series now focuses on the titular Outsiders, and the Team end up being very OutOfFocus with all of one episode to themselves in the first thirteen episodes, which even then was still mainly focused on Miss Martian (who's avoided being completely demoted via her association with the Outsiders). By extension, this means that Blue Beetle, Kid Flash II (the two most developed newcomers from ''Invasion''), Thirteen (the only ''Outsiders'' newcomer to remain on the Team), Wonder Girl (who already suffered from being OutOfFocus beforehand), and Static (an EnsembleDarkhorse who many were looking forward to especially due to him being ExiledFromContinuity in the comics), all have little if anything to do with the plot. Subverted in the second half of the season, with the characters from the Team gaining significantly more focus with the creation of Beast Boy's new public team, which features much of the Season 2 Team.
* TheyWastedAPerfectlyGoodPlot:
** Season 3 begins with fan-favorite characters Spoiler, Arrowette, and Thirteen already on the Team, and Cassandra Cain on Batman's team. Not only does this rob fans of seeing an origin story for any of them, it also means they're severely OutOfFocus. Also, Cass appears as her less-liked later (New 52) identity Orphan rather than Batgirl, which she was created and gained a following for until Spoiler replaced her in the role before the New 52 hit. Meanwhile, Barbara is Oracle, meaning that Batgirl's shoes are currently empty.
** [[spoiler: Wally West's birthday is November 11th (as shown in Season 1), and this season does pass through November, but the day is skipped over completely and is never referenced. It could have been an opportunity to more directly address how characters have dealt with his death, as only Artemis and Dick have really been shown directly dealing with grief, while it has to be inferred or assumed for everyone else, but it goes by ignored.]]
** Tim and Cassie's relationship. They only shared one dialogue exchange onscreen, and that was at the end of Season 2. This season opens up with Robin leaving with the Team without telling his longtime girlfriend, putting a strain on their unexplored relationship, and it was patched offscreen during "Illusion of Control", rendering the drama pointless if it was never gonna be shown. [[spoiler: Garfield claims to Tim that his relationship with her will be finished when she learns about the Anti-Light, but we don't see them talk after it's revealed to the wider League, and given how the League reacts well enough after they confess, it could go either way.]]
** Subversive and surprising it may have been, there's still no getting around the fact the show decided to resolve something as big as [[spoiler: Darkseid possessing the Anti-Life Equation and using it successfully on many of the heroes]] by simply having [[spoiler: Victor Boom Tube in, shoot off the visor Granny used to control Violet, and then have both proceed to swiftly and easily turn the whole situation around and snag complete victory, with no lasting consequences for the heroes.]] To say that is not what fans had been expecting/hoping for would be to put it mildly. “Nevermore” would indicate there's possibly another means for Darkseid to [[spoiler: obtain the Anti-Life Equation,]] but it can still feel like a pretty big wasted opportunity for fans who thought things were going to get much bigger after “Terminus”, rather than just have the heroes [[spoiler: return to Markovia]] for the finale.
** Provided you are of the position that [[NeverFoundTheBody Wally]] is dead and [[KilledOffForReal gone for good]] (which, of course, many are), then the reveal that the [[spoiler: whole 'meeting' between Artemis and 'Wally' being a deception by Zatanna and M'gann wastes a perfect opportunity to ''unambiguously'' confirm [[HesDeadJim Wally is dead]] and end any question/debate regarding his fate; give both of the characters some closure with one another; and maybe give Wally a slightly more satisfying send-off than his abrupt death in “Endgame”. Instead, it's revealed to have all been nothing but a trick. Artemis never went to Limbo and met Wally, M'gann used her powers to create 'Wally' from Artemis's own mind for her to speak to, meaning Wally himself was no more present than he was in Dick's hallucination in “Terminus”. It also renders everything “Wally” says to Artemis meaningless in hindsight, since, essentially, it's just Artemis talking to herself.]] Zatanna's claim about not being able to call back or contact the dead that have passed on at all can seem like a pretty arbitrary rule that hasn't been [[NewRulesAsThePlotDemands previously established]] (granted, it doesn't contradict anything either), existing just because the show doesn't want it to happen, perhaps because that would be too neat and straightforward in a show that prefers to be [[CruelTwistEnding twisty]].
** The idea of the heroes suffering a split from disagreement in how they should operate is never explored ''at all''. After the premiere, the heroes simply work separately and aren't shown interacting with each other. Little to no attempt is made to show how such a split would inevitably result in friction or bitterness between members on the opposing sides, and only brief passing nods are ever made at the effect it has on their personal lives.
** The finale mostly glosses over [[spoiler: any potential backlash the other heroes would reasonably have towards the Anti-Light for their deception.]] Unlike when [[spoiler: Jefferson, Conner, and Garfield [[WhatTheHellHero first found out]]]], the [[spoiler: other members of the League and Team [[TheVoiceless quietly]] accept what the group did and don't even seem particularly offended for the months-long deception.]] Kaldur, Wonder Woman, and M'gann [[spoiler: resign their positions]] by their own choice, as opposed to [[spoiler: their teams' demanding it.]] Much like after the undercover op in season 2, there's no indication their actions have resulted in any [[EasilyForgiven loss of trust or negative consequences for those involved.]] It's simply used to [[spoiler: make Black Lightning the new [[HighTurnoverRate Chairman]] of the Justice League, embracing a new, more idealistic philosophy, get Nightwing to rejoin the Team, and have the members of Batman Incorporated reintegrate into their respective teams.]]
* UglyCute:
** Forager, a squat bug-eyed Bug alien looks definitely inhuman but also endearing.
** More disturbingly, the sight of Halo reviving with half of her face burnt off can qualify.
* UnexpectedCharacter: Plenty of examples from Season 3.
** Arrowette ''was'' a member of the original Young Justice in the comics, but left the life of heroism behind permanently and post-''Flashpoint'' [[RetGone she has not returned at all]], until several years later with her reappearance in ''ComicBook/YoungJustice2019''. She makes her animated debut here, after having a small role as the little girl in "Insecurity".
** Spoiler has always been an EnsembleDarkhorse but has a long history of being shafted if not outright [[ExecutiveMeddling meddled with by executives]]. She was even ComicBook/{{Batgirl|2009}} for a little while and gained a big following as a successor to Barbara Gordon, only for the ResetButton to be hit and kicking her out entirely for a long time. So having Spoiler make her debut here was definitely welcome.
** Thirteen is quite a minor character in the comics, first being a ''Superman'' supporting character and then moving over to Blue Beetle, before the ResetButton was hit and she didn't come back until 2017.
** The Outsiders have several new recruits, and the one that sticks out is Forager, a very minor New God who died in 1989 and didn't come back until ''28 years later'' in the Creator/YoungAnimal title. He also had no history with the Outsiders in the comics, making his inclusion even more left-field.
** While it was expected that Barbara Gordon would return, it was thought that she'd still be ComicBook/{{Batgirl}}, not her MissionControl identity Oracle (which has long since been discarded in the comics). Though to be fair, many ''did'' believe (or hope) that she would eventually transition from her Batgirl identity to her Oracle persona (it being the role many fans prefer her in), but many assumed she would at least spend one more season as Batgirl and possibly suffer her crippling injury on-screen
** Even returning characters can count. Who seriously thought Black Spider of all people [[TheBusCameBack was going to come back]] after appearing in only two episodes of the first season (only speaking in the latter) and never showing up afterwards?
** ComicBook/{{Hardware}}, a Creator/MilestoneComics character, appears this season. Because of legal issues, Milestone characters are often tricky when it comes to adapting them[[note]]they own the copyright with DC only having the trademarks, and Milestone is no longer part of the DC Universe in the comics due to a dispute between DC and the [=McDuffie=] estate. It also prevented Rocket and Icon from appearing in tie-ins[[/note]] and rarely do they appear nowadays in other DC media. There's also his relative obscurity, as while initially planned to be the flagship Milestone character, he lost considerable ground to ComicBook/{{Static}} over time.
** Holocaust, another Milestone character, specifically one of its major villains, is surprisingly for the same reasons Hardware is, much less a fight against him and Terra.
** Kaldur, after having been absent in the marketing beforehand yet still confirmed to be in the series, was widely expected to return as Aqualad. Instead he returns as Aquaman, succeeding Orin.
** Cassandra Cain appears. The real surprise is that she hasn't exactly donned the Batgirl suit, rather a hooded ninja uniform, and she's already going by Orphan.
** Batwoman was confirmed to appear in the premiere only after the release of a set of screenshots from the episode, taking many by surprise.
** Donna Troy, after having relegated to being in the background and unseen in ''Invasion'', debuts in ''Outsiders'' under the name of Troia to the surprise of everyone.
** Kaizen Gamorra appears in the UN conference. For reference, Gamorra doesn't originate from DC proper, but rather the ''Creator/{{Wildstorm}} Universe'', as an enemy of ComicBook/{{Stormwatch}}. As [=WildStorm=] in general isn't featured much outside of comics, even less so than Milestone, it's definitely a surprise to see that.
** While ComicBook/LoisLane was expected to appear in Season 3 nobody also expected that both Clark and Lois are married here and both have a child who is no other than Jon Kent, who wasn't even ''created'' when the show first debuted (though Superman having a son, usually with [[SuperCouple Lois]], named Jon Kent had already occurred in alternate continuities decades before the introduction of the main universe version, and he had other sons before).
** Ultra-Humanite only appeared as a minor villain in one episode in Season 1 as part of the Injustice League, never seen again afterward. Few were expecting him to ever return, much less be promoted to a ''council member'' of the Light (and it helps [[DescendedCreator Greg Weisman himself]] had taken over the role).
** Bluebird is a lesser-known member of the Batfamily, and wasn't even ''created'' at the time the show first debuted. Her appearance in ''Outsiders'', albeit as just Harper Row (for now), came as a huge surprise.
** Henry Heywood, the name of three generations of Commander Steel, being mentioned as having a school named after him, which is where Victor Stone/Cyborg and Cisco Ramon (who may become Vibe) attend. The school mascot being the Steelworkers implies that whichever Henry Heywood the school is named after, he was Commander Steel at some point in the past.
** Cisco Ramon, Vibe in the comics, being a classmate of Victor/Cyborg.
** The existence of the Doom Patrol, since it would seem weird to have another superhero team unrelated to the Justice League. And it sadly turns out that they already died during the TimeSkip between season 1 and 2, similar to their fate in the comics.
** Wally's "ghost" appearing to Gar in "Nightmare Monkeys".
** The second half of the season featuring the ComicBook/SuicideSquad was a welcomed surprise, as it appeared they were AdaptedOut of this continuity, although of the members shown, only longtime member Captain Boomerang newly debuted on the team, with Black Manta (a member in the New 52 incarnation) and [[KillerGorilla Monsieur Mallah]] [[TeamMemberInTheAdaptation (who has never been on the team in any prior version)]], plus Amanda Waller, being the only ones to have appeared before.
** The Newsboy Legion being not only {{genderflip}}ped, but also being {{Composite Character}}s with ''Franchise/ScoobyDoo'' characters (including of Mayor Jones and Sheriff Stone from ''WesternAnimation/ScoobyDooMysteryIncorporated'').
** "Early Warning" introduces a RaceLift Dolphin[[note]] although her name isn't confirmed until "Unknown Factors"[[/note]], an Aquaman character who isn't necessarily obscure (unlike some other characters in the show, she has appeared in recent comics), but not prominent either.
** Celia "Jet" Windward of ComicBook/TheNewGuardians and ComicBook/GlobalGuardians was an unexpected character to make a speaking appearance, even if it was a very minor one.
* UnintentionallyUnsympathetic:
** Few people are shedding tears for Silas Stone after Victor [[WhatTheHellHero lashed out]] at him for turning him into a cyborg with the Father Box. From what we see of his relationship with his son, he's shown to be pretty apathetic and distant to the point he barely knows anything about Victor's school life (for reference, he chastises Victor for not doing well enough at school when he has a ''4.0 GPA''). And although we can forgive him for turning Victor into a cyborg out of desperation, he loses sympathy points when he instead [[NeverMyFault tries to pin the blame on the Justice League]] for Victor's condition since they gave him the Father Box, even though the League ''warned'' him of its dangers.
** M'gann may enter this territory in "Nevermore." She attempts to [[spoiler: give back her engagement ring to Conner]], heartbroken that he still can't forgive her for how she abused her powers in the past, while [[spoiler: Conner immediately declares otherwise and they happily reconcile.]] Only problem with that is in just the prior episode [[spoiler: she abused her powers to deceive Artemis by letting her believe she was communicating with Wally's spirit when it was really just a construct created by M'gann from Artemis' own mind.]] Conner, of course, [[LockedOutOfTheLoop doesn't know this]] but it's difficult to imagine he wouldn't regard the plan with similar distain when he considers her lying to everyone to be little different than her abusing her powers, and her actions in "Overwhelmed" are her abusing her powers again. Thus M'gann can be seen as [[KarmaHoudini receiving forgiveness even while she continues her previous behavior, only this time sucessfully keeping it hidden from Conner.]]
* WhatDoYouMeanItsNotForKids: The new series on Creator/DCUniverse is clearly meant for an older audience. While the first two seasons definitely had their edgier content, and may be one of the darkest shows to have aired on CN outside of anime, they still had to be written as appropriate for the kids due to network limitations and restrictions. But now, as a streaming-exclusive series, this most certainly is ''not'' the case.
** Greg Weisman referred to the content as "PG-13 towards R" as opposed to "PG towards PG-13" , and the first five minutes make it clear; we see a 14-year-old girl being trafficked as she's completely helpless, sees ''corpses around her'', forcibly turned into a monster, and then accidentally killed by Black Lightning, much to his horror. That's just the beginning.
** The first three episodes alone of Season 3 contain multiple examples of FamilyUnfriendlyViolence; including people being stabbed or shot to death with visible blood getting spilled, and a teenage girl getting [[FacialHorror her face burned off by a monster]] (though fortunately, [[HealingFactor she instantly and completely regenerates from her injuries]], but it was still a very gruesome sight).
** Later episodes feature several instances of characters before or after sex; underage teens consuming alcohol while screwing around with a firearm; one character being repeatedly killed, in some cases rather brutally.
* WhatDoYouMeanItWasntMadeOnDrugs: ''Nightmare Monkeys'' is certainly quite the BizarroEpisode, from its ArtShift to ''WesternAnimation/TeenTitansGo'''s art style to it being a parody of ''Series/StarTrekTheOriginalSeries''.
* WTHCostumingDepartment: For some reason, both Shiva and Talia have cleavage windows on their "work" costumes. It's odd because this is a show that doesn't unneccesarily sexualize its female characters. Shouldn't two women (including [[WorldsBestWarrior the canonical first or second best fighter in the entire DC Universe]]) who've been trained in combat by the League of Shadows know you shouldn't be running around fighting with your heart exposed and your boobs hanging out? Talia also had a perfectly fine, non-sexualized costume in the comics before her appearance in the show but they instead chose to [[ReusedCharacterDesign recycle her sexualized]] model from the ''WesternAnimation/DCAnimatedMovieUniverse''.

** [[https://www.youtube.com/watch?v=CiVCO7yVWZE The YU Phantoms OP theme]] for Season 4 uses an electric themed remix.

* AwesomeMusic: The YJ [[https://www.youtube.com/watch?v=PjLyg8S1iXY OP theme]] from Season 1.

** Really, this kind of fits every member of the "[=YJ4=]" (a nickname given to [[Comicbook/RobinSeries Tim]], [[ComicBook/Superboy1994 Kon]], [[ComicBook/{{Impulse}} Bart]], and [[ComicBook/WonderGirl Cassie]] after their transfer to Teen Titans) alongside OnlyTheCreatorDoesItRight; while Creator/PeterDavid didn't create any of them, he did construct the chemistry and interactions that made this comic successful while still adhering to their portrayals at the time in their own books. In contrast, Geoff Johns and other creators are often accused of not understanding the appeal of the relationships and frequently retconed their pasts and personalities. While some may argue that Johns managed to pull it off, almost no other writer has ever managed to make Young Justice fans happy. For evidence, go to the ComicBook/TeenTitans YMMV page and check out how Cassie is back in TheScrappy category.

** The finale mostly glosses over [[spoiler: any potential backlash the other heroes would reasonably have towards the Anti-Light for their deception.]] Unlike when [[spoiler: Jefferson, Conner, and Garfield [[WhatTheHellHero first found out]]]], the [[spoiler: other members of the League and Team [[TheVoiceless quietly]] accept what the group did and don't even seem particularly offended for the months-long deception.]] Kaldur, Wonder Woman, and M'gann [[spoiler: resign their positions]] by their own choice, as opposed to [[spoiler: their teams' demanding it.]] Much like after the undercover op in season 2, there's no indication their actions have resulted in any [[EasilyForgiven loss of trust or negative consequences for those involved.]] It's simply used to [[spoiler: make Black Lightning the new [[HighTurnoverRate Chairman]] of the Justice League, embracing a new, more idealistic philosophy, get Nightwing to finally rejoin the Team, and have the members of Batman Incorporated reintegrate into their respective teams.]]

** M'gann may enter this territory in "Nevermore." She attempts to [[spoiler: give back her engagement ring to Conner]], heartbroken that he still can't forgive her for how she abused her powers in the past, while [[spoiler: Conner immediately declares otherwise and they happily reconcile.]] Only problem with that is in just the prior episode [[spoiler: she abused her powers to deceive Artemis by letting her believe she was communicating with Wally's spirit when it was really just a construct created by M'gann from Artemis' own mind.]] Conner, of course, [[LockedOutOfTheLoop doesn't know this]] but it's ''very'' difficult to imagine he wouldn't regard such a plan with similar distate when he considers her lying to everyone to be little different than her abusing her powers, and her actions in "Overwhelmed" are her abusing her powers again. Thus M'gann can be seen as [[KarmaHoudini receiving forgiveness even while she continues her previous behavior, only this time sucessfully keeping it hidden from Conner.]]

** M'gann may enter this territory in "Nevermore". She attempts to [[spoiler: give back her engagement ring to Conner]], heartbroken that he still can't forgive her for how she abused her powers in the past, while [[spoiler: Conner immediately declares otherwise and they happily reconcile.]] Only problem is, in just the previous episode,[[spoiler: she abused her powers to deceive Artemis, having her believe she communicated with Wally's spirit when really it was just a construct created by M'gann from Artemis' own mind.]] Conner, of course, [[LockedOutOfTheLoop doesn't know this]] and it's very difficult to imagine he would be accepting of such a plan when he considers her lying to everyone to be little different than her abusing her powers, and her actions in "Overwhelmed" are her abusing her powers again. Thus, M'gann can be seen as [[KarmaHoudini receiving forgiveness while she continues her previous behavior, only this time managing to keep it secret from Conner.]] Zatanna was, of course, equally responsible for the ploy, but unlike M'gann, she doesn't already have a history of abusing her powers to trick others and isn't shown being forgiven for said previous abuses.

* RootingForTheEmpire: Everyone rooted for Deathstroke to beat the life out of [[TheScrappy Lagoon Boy]] in their fight, to the point where they actually wanted him to get ''killed'' by Slade.
* TheScrappy:
** Aquagirl is hated by some fans who believe her to have strung Kaldur's feelings along, when she rejected him and started dating Garth instead (despite the fact that her and Garth were paired together in the original comics). It doesn't help that any more possible character development occurred offscreen before her death (during the timeskip between seasons).
** Lagoon Boy is widely disliked. First off he's a ReplacementScrappy for [[spoiler:FaceHeelTurn Aqualad]]. Secondly, [[spoiler:[[DieForOurShip he's Megan]]'s new boyfriend]]. Third, he's incredibly annoying and an incredibly FlatCharacter. (Being loud, brash and spouting the catchphrase/expletive NEPTUNE'S BEARD! is all there else is to him.) Fourth, his powers ''suck''. (Puffing up like a blowfish, even if you get super strength or something, makes you impossible to take seriously). About the best that can be said is that [[IntendedAudienceReaction we're possibly supposed to dislike him]], given how the rest of the cast reacts when he's around.
