Adaptation Distillation: According to Word of God, they are drawing on the earliest Batman comics of the 30's, as well as the allusions to Alfred's time with the British secret service. Not to mention the inclusion of characters from the Outsiders.
Normally, Man-Bat is Batman's version of The Lizard; losing his hearing and wanting bat-sonar to compensate, he mad science'd himself and Jekyll & Hyde-ifies between the good Kirk Langstrom and the evil Man-Bat. In this, he's forced to become Man-Bat by Professor Pyg and Mr. Toad, and as Man-Bat he only fights Batman or commits crimes when under their brainwashing. Most of his screentime is as an ally of the heroes, and he becomes a founding member of the Outsiders.
Adaptational Villainy: Basically, Anarky and Professor Pyg switched places and Anarky went from Well-Intentioned Extremist to Magnificent Bastard. The original was a tragic, optimistic anti-hero with good intentions but wrong means. This Anarky is a self proclaimed sociopath and aimless terrorist that acts as a stand-in for the Joker. Makes unnerving sense if you read the miniseries Anarky.
Affably Evil: These incarnations of Professor Pyg and Mr.Toad. Pyg even freely gives medical advice to his enemies. Though the level of helpfulness this "advice" is varies. Such as believing he had to amputate Alfred's broken ankle.
Lady Shiva also is quite polite to her enemies.
Anarky is clearly enjoying himself most of the time.
Acrofatic: Humphry Dumpler can sure move for his size, having escaped Batman chasing him three times. Twice while carrying someone.
Apple of Discord: When Ra's al Ghul sets Gotham's villains on Batman, hoping one of them will bring him in for a reward, Batman beats them by deliberately surrendering to Magpie. Greed takes over and the villains take each other out to get the reward themselves, allowing Batman to walk away casually.
Arch-Enemy: The creators say they wanted to set up Anarky as Batman's archnemesis, rather than The Joker, due to the fact that they want to avoid "Joker stories".
Arc Symbol: The Argus Club seems to be heading its way here, as Bruce got an invitation to it in the first episode, and he finds a key with its symbol in Bethanie Ravencroft's desk.
Ascended Extra: The series focuses on Batman's less widely-known comic book foes, like Magpie and Professor Pyg.
Showing just how deeply they've dug into Batman's enemies, in the second episode "Secrets", a character named Lunkhead briefly appears. Lunkhead only appeared in (and was subsequently killed off in) Arkham Asylum: Living Hell. Daedalus Boch and Junkyard Dog, the two street artists hired by Anarky in the next episode, are from the same series (though Daedalus is more commonly known by the supervillain name "Doodlebug").
At least one site also commented that they assumed that Silver Monkey was a Canon Foreigner, but found that he actually does exist in the comic books.
Batman Gambit: In "Toxic", Batman lures Metamorpho to Stagg Enterprise to cure him by telling him that Simon Stagg was the one who exposed him to the gas which in turn will make Metamorpho go there to get revenge on him.
Simon Stagg: How did you know? How did you know he'll come? Batman: There's two things in life that everyone is powerless against: love and revenge.
We learn in "Family" that Batman has been using Tatsu to weaken the League of Assassins, and knew from the very beginning her story and that Bethanie worked for Silver Monkey.
Battle Butler: Alfred will be seeing some action, with him being established in the pilot as an expert hand-to-hand combatant.
Simon Stagg: Hold on, just who exactly are you?
Alfred: Didn't they tell you? I'm the butler.
Big Bad Ensemble: Between Ra's al Ghul, Anarky, Harvey Dent/Two-Face and Deathstroke. Ra's and the League of Shadows are the main threat for the first half of the season, culminating in "Reckoning", leaving Anarky to step up his game. In "Nexus" Harvey Dent steps in as a Hero Antagonist, trying to capture and unmask Batman and Deathstroke acting as the final Big Bad.
Big Blackout: The end of "Fall" has this occur to Gotham City at the hands of Ra's al Ghul.
Bittersweet Ending: "Alone" ends with Deathstroke defeated and unaware of who Batman is, and Batman realizing that he doesn't have to go it alone. The problems that come with it are that Batman is considered a public menace now, Harvey's highly implied to have become Two-Face, and Anarky is going to start his plans over from scratch now.
Bodyguard Crush: Inverted, as Dr. Burr had a crush on Tatsu before she became his bodyguard.
Book Ends: "Broken" starts with Humpty Dumpty reciting "All the kings horses, and all the kings men". When he appears to commit suicide, his destroyed robotic duplicate only repeats those words.
Bond Villain Stupidity: In "Choices", Killer Croc traps both Batman and Katana in a concrete block, leaving them completely helpless. Does he finish the job while he can? No, he leaves them to be crushed by the coming subway trains (any one of which has a one-in-three chance of killing them), though to his credit he at least sticks around to foil any rescue attempts.
Bottomless Magazines: Professor Pyg's Blunderbuss is apparently a semiautomatic that can fire multiple times without the need to reload, despite having no visible magazine anywhere on the weapon.
The machine guns in the series don't seem to have any signs of a magazine. Probably because Executive Meddling turned them into laser guns.
Batman throws at least ten sonic batarangs in the final confrontation with Humpty Dumpty, and throws them with such impunity that it suggests that he has many more.
However, averted at least twice. The first time is at the very beginning, when Batman points out to a crook he has only two bullets left. The second is in "Allies", when Gordon says they better start moving before the enemy learns how to count bullets.
Brick Joke: In "Tests", Alfred complained at the fact he thought he was really going to drive the Batmobile. In "Family" it appears he actually did get to drive it.
Brutal Honesty: Batman flat out states to Gordon that it was his fault that he couldn't protect Humphry in "Broken".
Call Back: In "Hunted" Professor Pyg told Mr. Toad that he should get his eyes checked when he mistook Alfred for Bruce. In "Instinct" he pulled out a monocle to see Batman.
Car Cushion: Magpie literally uses a car as a cushion after cutting herself free from Batman's grapping hook.
Chess Motifs: "Tests" uses much of it, and it's even deliberately invoked by Anarky. Alfred and Bruce play Chess early in the episode, Anarky taints the material on the big thug's boot with fragments of a chess flower, and Anarky and Batman fight in a very checkered area. Anarky even compares himself and Batman to the white and black kings (chaos and order).
Fittingly, the last shot of the series is Anarky playing with a chess set, with various Gotham characters represented as pieces. The Batman piece checkmates the Anarky piece. Anarky then resets the board.
The Commissioner Gordon: Gordon has yet to be established as this, falling in more of an Sympathetic Inspector Antagonist with Batman. He's also still a Lieutenant. After "Allies", he starts playing this trope straight, then in "Nexus", he becomes commissioner after Ra's has the old one killed.
Professor Pyg and Mister Toad seem to be taking cues from Poison Ivy (crazed eco-terrorist that identifies more with animals than people) and the Mad Hatter (speaking in nursery rhymes and taking inspiration from classic children's literature).
Magpie owes a bit to the Batman Returns version of Catwoman. She has a romantic interest in Batman, a Split Personality between a deranged villainess and a meek, friendly girl, and the ability to take an incredible amount of punishment. Not to mention the razor-sharp fingernails and black leather costume.
Katana seems to have been combined with Sasha Bordeaux, Bruce's former bodyguard, chauffeur, and crime-fighting partner.
Anarky takes traits from the Nolanverse version of the Joker (Batman's Arch-Enemy who sees him as a Worthy Opponent and styles himself as an agent of chaos) and the Riddler (egotistical planner who freaks out when his "perfect" plans are thwarted). There's also a bit of influence from Bat-Rogues who style themselves as an Evil Counterpart to Batman.note i.e. villians like Prometheus, Wrath, Killer Moth, and Owlman. Oh, and his costume is reminiscent of Moon Knight and The Spectre.
Alfred mentions in "Toxic" that they moved Dr. Burr to a new lab ever since "Safe".
In "Allies", Tobias Whale mentions Simon Stagg's arrest from the events from "Toxic".
Cool Car: The Batmobile, of course. This iteration is something of a cross between the Tumbler in the Nolan film series and the classic version.
Corrupt Corporate Executive: Wayne mentions that Simon Stagg's been part of many more shady dealings in business. Michael Holt's mode of business hasn't been disclosed, though he seems far more legitimate.
Could Say It But: In "Allies", Alfred indirectly tells Tatsu that she can go help Batman after Batman told her to stay behind thinking she's not ready yet.
Tatsu: This is stupid. We should be out there backing him up. Doesn't it bother you to sit here? You're trained for this, why does he think he could do it himself. Alfred: Actions, not words, gets the job done. Understand? (beat) Tatsu: Perfectly.
Crazy-Prepared: In "Allies", Batman reveals that he put tracking devices on Tobias' men during the time he was tracking Humpty Dumpty.
Darkest Hour: At the end of "Fall", The League's plan to make a black out in Gotham has succeeded, Ra's has defeated Batman, who is now the League's prisoner, and there might be problems of trust between Alfred and Tatsu after Ra's revealed that Alfred killed Tatsu's father
Dark Secret: The Soul-Taker Sword is this for Tatsu. While working for the CIA, Tatsu at one point went undercover as a member of the League of Assassins. After witnessing the power of the Soul-Taker Sword, she stole it, fled from the League, and went AWOL from the CIA because she believed that the sword was too dangerous to fall into the hands of either organization.
Dating What Daddy Hates: Simon Stagg's so against his daughter Sapphire dating Rex Mason, a security guard who works at his company, that he's willing to use him as a guinea pig for Project Metamorpho.
Deadpan Snarker: Bruce and Alfred, as per tradition. Katana as well. Not to mention the Batcomputer.
Batman: Computer, last known address of Humpty Dumpty. Computer:A wall. Batman:(eyes narrow) I'll rephrase...
In "Allies", Barbara gets in on the action by snarking at her captors. One might get the impression that she took a leaf from Pepper Potts' book on how to deal with them.
Death Glare: Tatsu seems to have one every time Dr. Burr tries to get closer to her.
Deconstruction: The writers have stated they wanted to provide a look at the physical discipline that would be required by Bruce Wayne if he were a real person. It has been mentioned that he eats an all-liquid diet and struggles to find techniques to minimize the amount of time he spends sleeping.
Diabolical Mastermind: Anarky has been described as the "Moriarty to Batman's Holmes". But Batman just thinks he's another nut in a costume.
Dirty Coward: Simon Stagg was going to offer double the amount of money Michael Holt was going to offer to Professor Pyg if he lets only him out and is willing to keep quiet about what he does to Holt and Alfred.
Dodge the Bullet: Lampshaded by Alfred in "Safe", after trying and failing to shoot Silver Monkey.
Alfred: The ones that can dodge bullets are always a bother.
Donut Mess with a Cop: Gordon ells one of his policemen to get a donut. He answers the wife wants him to cut down.
Driven to Suicide: Subverted with Humpty Dumpty. At first, it appeared that Humpty himself was standing on the edge of the castle wall, but it was just a statue of Humpty that fell to its "death".
Metamorpho tragically attempts this at the end of "Toxic". After being turned down by Sapphire, he smashes the ventilation system in the glass cage he's in and transforms into a gas, causing himself to be sucked out. It doesn't work and he's shown to be still alive at the end.
Empty Shell: Victims of the Soultaker Sword become this.
Enhance Button: The bat-computer is able to take a blurry reflection in Professor Pyg's gold blunderbuss and turn it into a completely flawless and properly aligned image.
The first few minutes show Batman foiling a robbery, using theatrics to elude the criminal's aim, taunts him by telling him why his other concealed weapons will be ineffective (later claiming to have lied about his chances) but then has his shoulder dislocated by the criminals partner. Thus we learn that this Batman is fearsome, analytical and also vulnerable. And then he demonstrates how badass he is by simply slamming his shoulder into a truck to pop it back into its socket.
Professor Pyg and Mr. Toad's introductions make their Those Two Bad Guys relationship and Eco-Terrorist status very clear.
Evil Counterpart: Anarky is being played up as one to Batman, to the point that he's using a white costume as opposed to the traditional red from the comic books, to contrast Batman's black.
Everyone Calls Her Katana: A fan example. As everyone seems to refer to her as Katana (even before she took up the title in the series) rather than her real name Tatsu Yamashiro.
Silver Monkey actually calls her Katana in "Safe", so it appears she's used the moniker before.
Faking the Dead: In "Epitaph", Bruce is assassinated in public by someone dressed as Batman. Needing the "Bad Batman" to be confident enough to make his next move, Bruce elects to let the public think he succeeded. The season finale ends with this still in play.
False Flag Operation: Dane Lisslow dresses as Batman and commits crimes to sully his reputation in "Epitaph".
Family-Friendly Firearms: Following the Aurora shootings in 2012, the firearms in the series were redesigned to look more futuristic, but the show itself makes it clear that the change is merely cosmetic. Gordon's sidearm clearly fires real bullets when he shoots off Magpie's claws in "Secrets", and the same goes for his subsequent warning shot at Batman. Gordon outright says his shotgun shoots bullets in "Allies".
Feel No Pain: Magpie, supposedly from the experiment she volunteered for at Blackgate. This allows her to survive a Car Cushion landing from a five story building without so much as a scratch and also appears to give her some degree of super-strength.
Foreshadowing: In "Secrets", Magpie pulls a Stealth Hi/Bye on Batman while he's watching a suspect, somehow crossing from an office in one building to the roof of another and getting into her fairly elaborate costume in the few seconds he looks away, which is extreme even by Batman standards. This is a hint that she's not actually the suspect in question.
Also in "Secrets", Daedalus Boch & Junkyard Dog, two graffiti taggers that briefly draw Batman's attention reappear in the next episode "Tests" as Anarky's goons.
In "Nexus", Harvey Dent brags to Batman about how he can't wait to personally escort him to Blackgate, where the "animals" will tear him apart. Harvey gets his exact wish in the episode titled "Animal".
Freeze-Frame Bonus: Pause to read some headlines in the newspaper in "Secrets". One suggests arson on warehouse fires, which may be some possible foreshadowing regarding Firefly.
In "Hunted", the news has "Tobias Whale found innocent of smuggling charges, Lt. Gordon vows justice."
Friendly Enemy: Tobias Whale. One-sided, like Magpie's "romance." Whale treats Bats like an old friend, though Bats makes it clear that's not the case and Tobias will definitely stab him in the back if it suits or serves him. Apparently, he just sees no reason to not be polite.
Getting Crap Past the Radar: In "Broken", if you're familiar with Humphry's backstory in the comic. It mentions that his grandmother "deceased under mysterious circumstances" where in the comic it's revealed he killed her, took her apart, and sewed her back together in attempt to "fix" her.
In "Secrets" if you look carefully in some scenes Magpie has noticeable Jiggle Physics. Then again her whole outfit is surprisingly risque for a Saturday morning cartoon, even with the TV-PG rating. Ditto for Lady Shiva in "Family".
In "Instinct" Bruce noticed a cheating husband.
The Ghost: The Penguin get's a few mentions but never shows up. Harvey is seen wondering if there's a significance behind the name, and partially obscuring a sketch of him. A later episode's news bulletin identifies Oswald Cobblepot as the Penguin Man.
Gondor Calls for Aid: In "Alone", Katana calls Barbara, Man-Bat, and Metamorpho to aid her and Batman in confronting Deathstroke.
Graceful Loser: After Batman defeats Humpty Dumpty, he deactivates the bomb suits that he trapped people inside.
Batman: He lost the battle and he's walking away honorably.
Gretzky Has the Ball: Alfred moved his King into Checkmate in "Tests", something that's against the rules in Chess.
Guns Akimbo: Alfred does this in a promo pic, though it turned out not to carry over to the actual series.
Thug: I thought you said the back-up piece was my best bet!
Batman: I lied.
In Name Only: Several of the villains shown thus far, while technically pre-existing characters, share little in common with their comics counterparts. In particular, Cypher from episode 9. In the comics he's just some guy with a Compelling Voice, while here he's a cyborg who can Wall Crawl and use Combat Tentacles to hack his victims brains.
Also, The Key, in the comics, is a guy with ever-changing mental powers based on the Ten Percent Of Your Brain fallacy. The key theme exists just 'cause he's a Batman villain and so must have a theme. In this, he's a cyborg (key-things in his hands) with the ability to basically break into and out of anywhere no matter how good their security is, and he can hack into anything and store the data within him (you get the feeling they wanted to use Cypher but he's too much of a mastermind to allow the plot that results to happen.)
Incredibly Obvious Bug: Batman places one on Katana when she's taken by Cypher in "Control." Presumably he has less obvious ones, since he planted some off-screen on Tobias Whale's mooks in "Broken" and they're still on them three episodes later.
Laser-Guided Karma: It seemed like Simon Stagg was gonna get away with turning Rex into Metamorpho and pinning the blame on Batman after he deleted the video of him doing it, but Batman managed to recover the deleted footage and had already sent it to Gotham PD. In "Allies", it's revealed that he was arrested.
Latex Perfection: Silver Monkey uses a face mask to disguise himself as a security guard. While we never see his real face, the disguise is nonetheless flawless.
Leitmotif: All of the criminals so far seem to have their own unique song that plays when the scene focuses on them. Batman has a couple of these as well, depending on if he's being dark and mysterious or is doing detective work.
Lighter and Softer: The series itself isn't any lighter than its predecessors, but its adaptation of certain characters is. Professor Pyg is merely a criminal genius instead of the deranged sadist he is in the comics, for starters. Likewise, several minor characters are taken from Arkham Asylum: Living Hell, and are extremely toned down for television.
Made of Indestructium: So far the Batmobile appears to be made of this. It has taken an industrial chainsaw, acid that melts concrete, and even cannon fire without so much as a scratch to the paint job.
Mad Scientist: Professor Pyg, according to the DC Nation magazine.
Man in White: Anarky's dressed in an all-white outfit, in order to contrast with Batman's black costume.
Make Me Wanna Shout: Mr. Toad has a supersonic croak that can send people flying and shatter glass.
Magpie's last name is Sorrow, which is a reference to an old nursery rhyme about magpies.
Humpty Dumpty has a less subtle one in his real name of Humphry Dumpler.
Mind-Control Eyes: You can tell when Cypher is controlling someone, because it gives them green eyes. (Not to mention the cable sticking out of their neck except for Jason Burr)
Mood-Swinger: Magpie, who goes from cheerful to angry in a split second. Clearly shown when she kicks Batman angrily, only to apologize afterwards.
Mundane Utility: Dr. Burr uses his device that can control the flow of electricity all over the world, to make a picture of Tatsu appear made of lights on the neighboring building. Though even Tatsu admitted that it was awesome.
Katana's bike and helmet use the same red and yellow color scheme as her classic comics costume.
Batman refers to the Industrial Area as a No Man's Land in "Allies".
Bruce's quip, "I own this restaurant", in "Instinct" is taken from The Dark Knight.
The logo for a plastics company resembles the belt of Plastic Man.
In "Fall", it's revealed in flashbacks that Alfred told Bruce not to ignore his limits, like in The Dark Knight. Also Batman's defeat at the hand of Ra's and the ninjas taking him prisoner are reminescent of the Batman vs Bane battle in The Dark Knight Rises.
In "Hero", during their first fight against Deathstroke, Tatsu is caught in an explosion and buried under collapsed rubble. When Batman arrives to dig her out, he carries his injured sidekick in his arms, just like he did with Jason Todd in A Death In The Family.
No-Holds-Barred Beatdown: In "Animal", Batman gives a beating to Killer Croc so brutal that the prisoners in the audience are struck silent by the savagery.
No Kill Like Overkill: The Failsafe to Wayne Manor. Locks down the manor, keeping anyone from getting in or out, and also comes with surface-to-air missile launchers.
Not That Kind of Doctor: Inverted when Alfred has to inform a scientist smitten with Tatsu that he's not, in fact, a medical doctor. He remains undaunted in giving her aid, despite the obvious fact that his help is neither wanted or actually useful.
Burr: Give me room, I'm a doctor! Alfred: Wait! Are you a medical doctor? Burr: I am tonight.
Oh Crap: Batman has one in "Broken" when he realizes Humphry Dumpler is in Gordon's house.
Opt Out: Junkyard Dog and Daedalus instantly give up fighting Batman during their third confrontation, especially when they knew that they were just being used to slow him down. Batman still knocks them out, though.
Outrun the Fireball: When breaking into Pyg's hideout in "Hunted", Batman outruns an explosion before it can get him. They he has to outrun another on the way out.
Paper Cutting. During a fight with Lady Shiva, Katana manages to leave a very thin nick on her cheek with the Soultaker Sword.
Justified, as she specifically mentions she wants the League of Assassins to know who she is when she beats them, even taking the same codename she had when she infiltrated them.
Pig Man: Professor Pyg wears a pig mask that makes him appear to be a mix between man and pig.
Power Fist: The big thief in the pilot has a pair which he uses to hit Batman with the door to a bank vault.
Pragmatic Adaptation: Magpie's redesign borrows from more contemporary artists in this era, as her outlandish eighties design probably wouldn't work in this day and age, as well as giving her more of a connection to the bird she's named after.
Prison Riot: Killer Croc and his henchmen incite a Blackgate riot in "Animal".
Reality Ensues: The show does its best to give a more realistic feel to the series to show what Bruce would need to do to pull off Batman in real life, such as reducing his sleep and liquid meals. Also his Batcomputer usually comes up with a statistic on how realistic his chances are to pull off what he is about to do.
Race Lift: Of sorts. In the comics, the Soultaker Sword was forged by Muramasa in Japan. Here, its origin is unclear, but it appears to be made of jade, implying Chinese origin, the blade is covered in unidentified runes, and a reference book implies that it's been around since ancient Egypt.
Red Herring: In the episode "Secrets", Batman makes a connection between Magpie and psychologist Bethanie Ravencroft. When he goes to investigate as Bruce Wayne under the pretenses of becoming a client, he discovers various items that Magpie has stolen in Ravencroft's desk. Coupled with their similar appearances, one would be lead to believe that Ravencroft was Magpie. It turns out that it's actually Ravencroft's secretary who has multiple personalities. She wears a wig similar to Ravencroft's hair, leading to the similar appearance.
Rich Idiot with No Day Job: Who else? But it's clear that Tatsu fully believes Bruce Wayne is this and is pretty much the main reason she doesn't think highly of him.
Rogues Gallery Showcase: "Reckoning" serves as this, featuring, in addition to Ra's al Ghul and Lady Shiva, Prof. Pyg, Mr. Toad, Mapgie, Tobias Whale, Phosphorus Rex, and Cypher.
Scenery Porn: The creators have made a point of emphasizing the geography of Gotham. Hence the many dramatic shots of the city.
Secret Test of Character: Bruce seems to be putting Katana through one, starting by entering his study while she can see him then using the secret entrance to the Batcave to see if she'll figure out it's there.
"Family" shows that Katana aced her tests, and gets to discover that Bruce is Batman and to enter the team.
Set Swords to Stun: Averted. Katana's sword is clearly sharp and lethal, if she cared to use it in that fashion.
Sherlock Scan: Batman showed this off when he noticed the victim of Magpie was missing a watch and how Katana knew Alfred.
Mr. Toad is the one who drives Professor Pyg's car, except he's a better driver than the other Mr. Toad.
The Head of Security in "Safe" is named Mr. Reese, also could count as a foreshadowing as Mr. Reese sounds like Mysteries, to which it turns out he's actually Silver Monkey in disguise.
Slasher Smile: Humphry sports a pretty creepy grin when he's inside Gordon's house. Got a pretty creepy chuckle to go along with it too.
Smart People Play Chess: Bruce and Alfred debate each other while playing chess in the Bat Cave. Subverted (most likely unintentionally) when Alfred moves his own king into checkmate, which is an illegal move.
Soft-Spoken Sadist: Lady Shiva's voice is remarkably mellow even as she kills Ravencroft with the Soultaker Sword and promises to torture Silver Monkey for his betrayal.
Taken A Level In Badass: Anarky went from being a whiny minor villain in "Tests" to a guy who can take out three Assassins, steal Ra's al Ghul's body, and make a deal with Lady Shiva for his return, and live by the time of "Sacrifice".
He has also, during his villainous gambit in the episode "Nexus", taken on Katana and Batman both to almost a standstill- almost, meaning they do eventually pin them. ...but not before he puts a proximity-activated bomb on each of their wrists, himself included.
Did we mention his gambit involved bombing the mayor?
Tempting Fate: Mercilessly lampshaded by Alfred and Tatsu in "Fall", when Bruce gushes about the potential of the Ion Cortex. Things do indeed go wrong, oh so very much.
Thou Shalt Not Kill: Another of Batman's old standbys. He stops Katana from killing a League of Assassins ninja and lectures her on it. Later in that exact same episode, he has no problem with knocking ninjas off their bikes during high-speed chases, which they all conveniently survive.
Throw Away Cannon: As Humphry sees Batman scaling the castle wall, he just throws his cannon at him.
Time Skip: "Nexus" is set six months after "Reckoning", just enough time to clean up the mess from Ra's al Ghul trying to take over the city.
Tragic Villain: Most of the villains on the show fall into this, especially if you exclude those affiliated with the League.
Magpie's probably the most heart wrenching example, as she started off as a basically good person with kleptomania, but the treatment they gave her (which she volunteered for in hopes of being cured) ends up shattering her mind, and eventually erases her good persona entirely. Even after that, the Magpie persona is largely sympathetic, as beyond her compulsion to steal she mostly just wants to be loved; it's her complete lack of impulse control and her own emotions that makes her a villain. Even Batman feels sorry for her, and of course because it's that kind of show his attempt to help her only makes things worse.
Metamorpho's another one, as none of what happens to him is his fault and if any of the major players in his life would just treat him with a little kindness everything would be fine. They don't.
Humpty Dumpty is yet another one, and is equally heartbreaking. He tried to do the right thing by testifying against his Bad Boss Tobias Whale, but was horribly injured and driven insane by Tobias' vengeance. Humpty is left basically a super (tactically) intelligent child, who mostly just wants to play games. Unfortunately, his games involve (somewhat justifiably) getting even with the people who either attacked him or failed to protect him, so he ends up drawing the attention of Batman, who naturally tries to help him. it doesn'twork.
And then there's Lunk Head. He used to be a basic (albeit strong) mook, but a fight with Batman left him comatose and damaged his brain. Nowadays he's basically a gigantic child who *wants* to be good, but is just a little too stupid and immature to control himself. At one point he's coerced into breaking out of jail (which he initially doesn't want to because he knows he's been bad and belongs there) with the promise of candy. And, once more with feeling, because it's that kind of show he doesn't even get the candy. Instead, he gets betrayed by his only friend and pushed off a ledge.
Adding to the list, there's Jason Burr, who starts off as a straight up good guy, and still wants to be one, but suffers from residual effects of Cipher's mind control that force him to betray his friends and try to kill his love interest.
In a later episode, we find out that Katana's father, a well-intentioned guy for the most part, was blackmailed into betraying his best friend Alfred, making him one of these. And, again, because it's this show he dies for it.
Triple Shifter: With the help of "hormone free bovine glands", Batman's down to 4 hours of sleep a night. He's currently working to get to two.
The Unfought: So far, Humpty Dumpty is the first villian that Batman hasn't engaged in hand-to-hand combat in the series, but that might change later on.
Simon Stagg. He was willing to abandon an injured Alfred after Alfred saves his life and he doesn't even thank Batman for rescuing him but he scolds him for almost getting them killed.
Averted with Michael Holt, who wasn't going to abandon Alfred after he saves them and helps him out from the oil rig.
Uptown Girl: Sapphire Stagg is this to Rex Mason, who works as a security guard at her father's company. Predictably, her father doesn't approve and goes to rather...extreme lengths to end the relationship.
Villain Exit Stage Left: Used even more commonly than in previous Batman series. So far the only supervillain whom Batman has actually captured at the end of an episode is Magpie (though some of the more low-key villains have also ended up in jail).
Villainous Crush: Magpie has a thing for Batman, though it's ultimately one-sided.
Villainous Rescue: Lady Shiva shows up to save Batman and Katana from Silver Monkey in "Family".
Watching a Video Game: The segment in "Games" where the characters have to stand on lighted tiles and jump to other ones when they start flickering is very reminiscint of certain platforming challenges.
Well-Intentioned Extremist: Professor Pyg and Mr. Toad want to protect nature, and they'll hunt and kill anyone in the way of that goal.
"Lady Shiva: You will be generously rewarded for your services Dr Burr. Welcome to the League of Assassins."
From "Fall": "Ra's al Ghul: Rest in peace, Gotham City."
What the Hell, Hero?: Katana calls Batman out on this in "Family", pointing out how his plan to cause infighting in the League of Assassins killed Bruce, left Ravencroft a soulless husk, and allowed the League to reclaim the Soultaker Sword.
What Happened to the Mouse?: In "Alone", after Commissioner Gordon saves Harvey Dent, now Two-Face, from Anarky, Harvey walks off, talking about his plans. The episode then moves on to the final confrontation between Batman and Deathstroke, leaving Harvey's next move for another episode.
Wounded Gazelle Gambit: Staggs actually tries to pull one of these in "Toxic", making it sound like he was just an innocent victim and it was all Batman's fault. Too bad he didn't count on Batman finding the video footage he deleted and sending it to the police.
Worthless Yellow Rocks: Inverted with Magpie. She's stolen millions of dollars in equipment, but she couldn't care less about that. She just likes them because they're shiny.
