* AudienceAwarenessAdvantage: Dana gets a lot of flack from some fans for not always forgiving Terry when he misses dates because of Batman duties and making his life difficult, even though as far as she knows, he's just an old man's part-time assistant who's doing a ''very'' bad job of balancing his new responsibilities with his prior relationships.
* AuthorsSavingThrow[=/=]CharacterRerailment: In ''The New Batman Adventures'', Mr. Freeze went on a rampage due to losing his body and Nora, and was going to end it by essentially destroying Gotham. Fans complained about this due to undoing the ending of ''Subzero'', where Freeze finally finds closure, as well as seeming out-of-character. ''Beyond'' dials him back, showing him [[TheAtoner trying to own up to his horrific actions]] in his sole appearance, but becoming a villain again after [[DespairEventHorizon one more kick in the gut]], and then finally [[KilledOffForReal dying]], trying to keep Terry from saving his life.
* SugarWiki/AwesomeMusic: The series itself has an amazing opening sequence and music in general,
** In one episode, Bruce Wayne has to save Terry from Inque. We are treated to a re-orchestrated version of the original [[WesternAnimation/BatmanTheAnimatedSeries Batman Theme]] during the fight.
** One episode featured Bruce and Terry attending a Batman ''musical''. The musical, unfortunately for Bruce, is really campy and almost seems like a musical version of the Adam West series, albeit with the characters in their WesternAnimation/BatmanTheAnimatedSeries clothing. It's hilarious for the ''fans'' though, with the purposely-corny numbers having NarmCharm and purposely invoking the SoBadItsGood trope.
-->'''Bruce:''' (*glaring at Terry at the end of a really campy song*) [[SugarWiki/FunnyMoments You hate me, don't you?]]
* BaseBreaker:
** Max. Fan reactions to her introduction ranged from considering her the best part of the series and thinking she was sold short (and often accompanied by [[FanPreferredCouple shipping her with Terry]]) to considering her the worst character yet and hoping that she'd just die and stop taking screentime away from everyone else. Her BaseBreaker status also extends to the development team; according to [[WordOfGod Bruce Timm]], some of the writers were unhappy about her inclusion and used Bruce Wayne to voice their own opinions of her, while Alan Burnett at least wanted to [[PromotedToLoveInterest promote her to]] LoveInterest.
** Terry himself has a sizeable hatedom, mostly Bruce Wayne fans who dislike the idea of a new Batman taking over from Bruce, or dislike that Batman was made YoungerAndHipper. He's often called "emo teen" and "merely a Robin" by such fans.
* BrokenBase: The [[NoYay offscreen relationship between Bruce and Barbara]] had always been [[FanonDiscontinuity disliked on varying levels]] by the fandom. However, the reveal in the ''Comicbook/BatmanBeyond'' comics that Bruce had impregnated Barbara just weeks before she had re-entered a seemingly happy relationship with Dick was very divisive. Some found it gutwrenching, and thought it appropriately explained why Bruce, Dick, and Barbara were estranged from one another for so long. Others thought it was too much like a bad soap opera, and that the Bruce-Barbara relationship should never have been revisited in the first place.
* CompleteMonster: Besides SelfDemonstrating/TheJoker from ''WesternAnimation/BatmanBeyondReturnOfTheJoker'', the series itself has one in Blight, AKA Derek Powers, a CorruptCorporateExecutive and the ArchEnemy of Terry. In order to test his latest chemical weapon, Powers purposefully infected Harry Tully, a member of his staff, with it. When Tully leaks the information to Terry’s father, Warren, Powers had Warren murdered to cover it up. Later, Powers sold the weapon to a Kaznian diplomat who wanted to wipe out resistance on his border. To promote his product, Powers showed the diplomat pictures of [[BodyHorror Tully’s gradual death at the hands of the chemical]]. Other crimes include committing industrial sabotage, exiling his son, and polluting the ocean by dumping radioactive waste into it. He played a part in [[WoobieDestroyerOfWorlds Mr. Freeze]]'s tragic demise as well; he used Freeze as a guinea pig to cure his own condition and when Freeze wanted revenge, Blight brutally crippled Freeze with his radiation. He’s also responsible for the creation of the super villain, Shriek, who he hired to assassinate Bruce Wayne for getting in the way of his plans to bulldoze Gotham's historical district for profit. There's also his response to Terry's use of YouKilledMyFather as a hint to Batman's real identity:
-->'''Blight:''' Do you have the ''slightest'' idea [[ButForMeItWasTuesday how little that narrows it down?]]
* ContestedSequel: Mostly averted; the series is overall considered a really good sequel to WesternAnimation/BatmanTheAnimatedSeries and has been well-received by the majority of fans. The fact it came out while the previous series was still running, making it a spin-off rather than an actual sequel, probably helped.
* DamselScrappy: Max Gibson is often considered this by her detractors. This tendency is best displayed in the episode "Final Cut", where she ignores Terry's instructions and snoops around for clues, leading to her getting attacked by an assassin. Terry has to leave his post protecting the assassin's target to rescue her, which results in the target getting mindwiped with a hidden bomb ready to explode thanks to his DeadManSwitch.
* DieForOurShip: Dana, big time, from Terry/Max and Terry/Melanie fans.
* EnsembleDarkHorse:
** The Joker's personal [[WesternAnimation/BatmanBeyondReturnOfTheJoker gang of Jokerz]], especially Dee Dee, are inordinately popular for only appearing in TheMovie. Fans were naturally thrown a bone when ''JusticeLeagueUnlimited'' went to that time and they were used as Chronos' flunkies.
** For someone who only appeared in 3 episodes, [[DatingCatwoman Melanie Walker]] made an exceptionally positive impression on viewers and shippers alike, being one of the most popular romantic alternatives for Terry.
** [[MadBomber Mad Stan]] was a one-note villain simply there to force Terry to miss his date with Dana. His outright ''insane'' AxCrazy personality made him popular among fans and he reappeared in several episodes, finally getting to be the main antagonist when ''WesternAnimation/TheZetaProject'' crossed over. The best part: due to Zeta's naive, cheerful nature, he and Stan actually get along well, resulting in this hilarious line:
--->'''Zeta:''' What a nice guy. [[DrivesLikeCrazy But he should really learn to drive more carefully.]]
* EpilepticTrees: Spoofed in ''WesternAnimation/BatmanBeyondReturnOfTheJoker'' when Terry starts rattling off a list of increasingly unlikely theories as to why the Joker's still alive and kicking. Bruce eventually tells him to shut up. His theories also include a ShoutOut to CaptainAmerica.
* EvilIsSexy: Inque. [[spoiler: It runs in the family, as her daughter Deanna is pretty good looking also.]]
** Also Queen and Ten from the Royal Flush Gang count for this, [[spoiler: until Ten defects from the group.]]
** Curare also to a certain degree, [[spoiler: though the official artwork of her real face makes her a ButterFace.]]
** Also [[spoiler: Frion from the Terrific Trio.]]
** Dee-Dee from the Jokerz in the movie. Probably helps that their Grandma is [[spoiler: Harley Quinn]]
** Stephanie Lake also qualifies as this.
* FanPreferredCouple: [[DatingCatwoman Terry and Melanie]] and [[PlatonicLifePartners Terry and Max]] are in the running for the top spot, if fanfiction is any indication. Alan Burnett even tried to pair Max and Terry in one episode, to the objections of Timm, who had had no such intention when he proposed the episode ([[http://www.youtube.com/watch?v=lAheG04f9B8 Here at 1:55]]).
* FoeYay: Ten and Batman.
** Also Inque and Batman. [[spoiler: She even kisses him on the mouth to prevent him from relaying a warning to Bruce about her trap for him in one episode.]]
* FunnyAneurysmMoment: While going over Presidents with Max, this exchange occurs (This episode was produced in 2000 when the election was going on; then it first aired ''during'' the month-long legal battle between UsefulNotes/GeorgeWBush and Al Gore, making it even more hilarious.):
-->'''Terry:''' [[UsefulNotes/GeraldFord Ford.]] [[UsefulNotes/JimmyCarter Carter.]] [[UsefulNotes/RonaldReagan Reagan.]] [[UsefulNotes/GeorgeHWBush Bush.]] [[UsefulNotes/BillClinton Clinton.]]..
-->'''Max:''' Yeah?
-->'''Terry:''' I dunno.
-->'''Max:''' C'mon. Clinton was the fun one, then came the boring one.
** This would have been doubly hilarious if Al Gore, who actually has a reputation for being boring, had won the 2000 election.
* HarsherInHindsight: The Jokerz are a gang of youths inspired by SelfDemonstrating/TheJoker to commit crimes, including murder. Well, we ended up getting a real life example with the Aurora Theater Shooting during the premiere of ''Film/TheDarkKnightRises'' in 2012.
** Henry Rollins playing a quasi-suicidal mad bomber, after he severely hurt his reputation in 2014 with an article where he viciously insulted anyone who commits suicide in response to Robin Williams doing it (and while he was currently on [[TheLegendOfKorra a show]] with Williams' daughter, to boot).
* HilariousInHindsight: Being set in the future tends to attract this from time to time, whether it is Terry quipping "Who reads newspapers anymore?" (in "The Winning Edge") or reviewing the Presidents with "Clinton was the fun one, then came the boring one." (in "Mind Games"). By the time of the series a perfect score is 2400 (see the example in SecondPlaceIsForLosers), which as of [[http://en.wikipedia.org/wiki/SAT#_2005_changes 2005]] it has been.
** "[[ItsPronouncedTroPAY My father's name was pronounced "Raysh",]] [[Film/TheDarkKnightSaga not "Razz"]]."
** In the pilot episode, a Jokerz member says "[[Film/TheDarkKnight Let's put a smile on his face]]," while brandishing a knife. Ever since TDK came out, one may now consider it retroactive fanon that that particular Jokerz member was intentionally quoting one of the signature lines of his "hero."
** In "Countdown," Zeta disguises himself as Terry in costume to escape the NSA. Diedrich Bader would later voice [[WesternAnimation/BatmanTheBraveAndTheBold a different Batman]] years later.
** During "Disappearing Inque" while interrogating a captured Terry about who Bruce is, Inque asks [[spoiler: "Is he your father? ''Grandfather?''"]] Come an episode of JusticeLeagueUnlimited a few years later, we find out [[spoiler: Bruce ''is'' Terry's father.]]
** The episode "Zeta" starts off with a lecture about the theory that one's genetic makeup makes a person inclined to act a certain way and brings up the question of free will. Terry wonders if being Batman makes him naturally suspicious. [[spoiler: As Terry would find out later, he does have Batman's genes that might make him naturally suspicious.]]
* JerkassWoobie:
** Willie Watt.
** Carter Wilson/Terminal
* MemeticMutation: BLOW IT ALL UP!
** [[http://www.youtube.com/watch?v=HeHUQAnzpF0 GET BACK IN THE KITCHEN!]]
* MoralEventHorizon: [[spoiler:Ra's al Ghul. Murdering your daughter to save yourself via BrainUploading and then parading around in her body, living her life. Geez.]]
** And then [[spoiler: Robert Vance, or at least the computer program with his memories [[WhatMeasureIsANonHuman depending on how you look at it]], tries to do the exact same thing to his own grandson.]]
* NauseaFuel: In ''"Rebirth Part II"'', Blight designs a virus that rapidly causes damage to cells in organisms. He shows the effects to one of his allies, first showing a plant utterly disintegrating in seconds due to the effects, and later on a cow and human. We never see the end result but judging by what happened to the plant and how the guy viewing looking ready to vomit, its safe to assume it was a little messy.
** See {{Squick}} below.
** In-universe, just being ''around'' Blight long enough is this for anyone not wearing a protective suit.
* NightmareFuel: ''Lots.''
** The end of "April Moon", as a drill bit slowly approaches the POV of the viewer:
--> "I understand. No holding back."
** From "Meltdown": [[http://www.youtube.com/watch?v=Ft6mNPeqa6Y Remember, there might be some momentary discomfort.]]
** The episode "Lost Soul." Just the way the Robert Vance program ([[WhatMeasureIsANonHuman or Vance himself, depending on how you look at it]]) ''looks'' on the computer screen with the dead eyes and the ghost-like pallor is NightmareFuel by itself. The events of the episode just mix in kerosene with the NightmareFuel, and the end where [[spoiler: as he's being deleted we hear his memories going back to childhood, ending with the heartbreaking sound of child!Vance asking for his mama]] just dumps the entire container on and turns it into NightmareFuel. There may not be a single episode that can rival how creepy the villain was and how disturbing that end scene was.
** The MonstersWeek from "Earth Mover". A freaking ''living corpse'' who can control the dirt and attack you ''anywhere''.
* NoYay:
** "Out of the Past". Bruce and [[strike: Talia]] Ra's. Terry and Bruce are as {{Squick}}ed as you would expect. Bruce even [[LampshadeHanging lampshades]] it.
* RescuedFromTheScrappyHeap: Most viewers would have no idea that Bruce Wayne's loyal guard dog Ace was a retooling of the '50s era Ace the Bat-Hound. Most viewers would not even know Ace the Bat-Hound ''existed'' (at least before the ''WesternAnimation/KryptoTheSuperdog'' show where he was a recurring character or his appearance in ''WesternAnimation/BatmanTheBraveAndTheBold'').
* {{Shipping}}: Terry/[[SecretKeeper Max]] and Terry/[[DatingCatwoman Melanie Walker]] have their fans. Believe it or not, so does [[OfficialCouple Terry/Dana]] and inevitably for better or worse, so does [[{{Squick}} Terry/Bruce]].
* ShippingGoggles: Terry/Max shippers sometimes claim that the two are pining for each other or in denial about their romantic feelings, ignoring the time the two were ''on a date'' (as part of a case) and Terry even noticed how good-looking Max was, only for Max to completely ignore his notice and nothing else coming of it. When Terry gives Max a chaste peck on the cheek in [[ComicBook/BatmanBeyond the comic]], shippers cried ShipTease, ignoring how neither character treated it as at all romantic.
* SoBadItsGood: The episode "Out of the Past" is arguably one of the darkest and most depressing in the series... but it starts out with one of the [[http://www.youtube.com/watch?v=K2p02DfyzCE most ridiculously-goofy examples]] of StylisticSuck in a cartoon. Complete with a lampshade from [[DeadpanSnarker Bruce]].
--> '''Bruce''': You hate me, don't you?
* SpiritualLicensee: ''WesternAnimation/BatmanBeyond'' is a Spider-Man cartoon. Looking past the WakeUpGoToSchoolSaveTheWorld premise, Terry is a wisecracking teenage superhero driven by his desire to atone for his past misdeeds and the death of a father figure. He's effectively Peter Parker in the Batsuit. Even the RoguesGallery is pretty similar to Spidey's. (Inque = Sandman, Spellbinder = Mysterio, Stalker = Kraven, Shriek = Shocker, Blight = Green Goblin, etc.)
* {{Squick}}: Shriek's creepy little mutant henchman, who likes nothing more than to sit on the floor with a tuning fork that directly stimulates a body's pleasure center. Complete with eyes rolling back and moaning. [[BrainBleach Who else needs a shower after that?]]
** One of Inque's darker attempts at killing Batman. She puts the squeeze on Terry in order to force his mouth open before ''[[OrificeInvasion shoving herself down his throat]]'' in order to suffocate him. After Bruce uses a fire hose to get rid of her, we get a GoryDiscretionShot that saves us from the view of Terry actually puking, but we hear every agonizing heave and see Inque's leftovers spilling onto the ground.
* StrangledByTheRedString: Terry and Melanie. They met seconds after he got conveniently dumped by Dana, talked a little, kissed under the rain then they're a couple and Mel is unwilling to leave Gotham because of him. Maybe justified by the length of the episode.
* TheyWastedAPerfectlyGoodCharacter: An issue fans took with the series was that several interesting villains were never used for more than three episodes at most before getting dropped for no apparent reason.
** Blight was the biggest offender. He was the BigBad of the first season and set up as the BigBad of the series period... But nope, he never returned after the first season's finale. The character did reappear in the comics, however — his body survived, but he doesn't seem to remember anything about his past life outside of hatred and a desire for vengeance for Batman and Paxton Powers, and was eventually made into a target for the Stalker, and was eventually [[spoiler: killed by being caught in a blast furnace.]]
** Given the number of shippers rooting for her, Melanie may also count as this. For one of the most popular romantic pairings in the show, you'd think she'd appear in more than three episodes. She does appear again in the comics though.
** Most of Terry's supporting cast were sorely underused, most prominently his mother Mary, followed by his brother Matt and his girlfriend Dana. For all that they tried to make Terry different from Bruce, they neglected the characters in Terry's life that Bruce could never have had. Regarding Matt specifically, there are those who lament the missed opportunity of evolving Matt's character into a Robin Beyond to match Terry's Batman Beyond. It doesn't help that any recent comic that ''does/did'' feature Terry never bothers/ed to explore that avenue, either (assuming Matt shows up or is referenced at all), nor does some other fans' general ambivalence toward Matt, at the best of times, help either.
** The writers [[WordOfGod admitted]] in retrospective that they didn't do much with Dana outside of making her a [[TheObstructiveLoveInterest "nagging girlfriend."]]
** Zander. Great ShadowArchetype, interesting version of a ShelteredAristocrat, then, well...[[spoiler: he's turned into a dinosaur and killed off.]]
** Victor Fries is one of the few members of Batman's original rogues gallery to be given a comeback, able to maintain a conversation with Terry (unlike, say, Bane), given new motivations (either revenge on Powers or atoning for his past), and given a new, enhanced suit. [[spoiler: Then he commits suicide]]. His perspective on the new Gotham and the new Batman are never explored.
* WhatDoYouMeanItsForKids: Violence ? Check. [[FamilyUnfriendlyDeath People dying horribly]] ? Check. Lots of [[Radar/BatmanBeyond sexual undertones]] ? Check. Drugs ? Check. Yeah, [[SarcasmMode definitely a kid-friendly show]].
* TheWoobie: Dick Grayson hasn't had a good life since The New Batman Adventures ended. He gets back together with Barbara and is ready to propose, only to find out ''from Bruce'' that she was pregnant with Bruce's child from a relationship that Barbara kept hidden from Dick. After a period of estrangement, he works with Bruce one final time, only to be shot and critically injured due to a tactical error on Bruce's part, and then left behind for the paramedics. In the future, he reaches out to Terry to mentor him. When Terry travels to the Justice Lords timeline to visit his alternate universe father, he neglects to answer a distress call sent by Dick, resulting in Dick's capture by Davis Dusk.
