"Let's hope it's not the Batman that brings out the freaks..."
Son of wealthy entrepreneurs Thomas and Martha Wayne, who were gunned down one evening coming out of a theater as a young Bruce watched. Vowing to take revenge on the criminal underworld, he spent years abroad to hone mind and body so he could act as Gotham City's midnight vigilante, using stealth and the imagery of a bat to intimidate his prey. He is the CEO of Waynetech, developer of technologies such as his elite crimefighting vehicle and a device called the "Bat-Wave". The Batman follows a 26-year old Bruce during the adventures in his third year as Batman.
The Wayne family's loyal retainer who saw Bruce through his emotionally dark childhood following the murder of his parents. He is privy to Bruce's secret identity as Batman and maintains the Batcave whilst Bruce is in the field.
Character Development: In the early episodes, Alfred wasn't too happy with Bruce's work, often suggesting he give it up. By the time of the season three episode "Gotham's Ultimate Criminal Mastermind", his opinion had changed considerably, to the point where he was willing to die rather then have Bruce's secret be revealed.
"Gotham needs the Batman more then you need a butler!"
Daughter of Gotham City Police Commissioner James Gordon who joins Batman's war on crime during the show's third season, who takes on the persona "Batgirl" when patrolling the city. Unlike the comics, Batgirl joined Batman before Robin.
Voiced by: Evan Sabara, Jerry O'Connell (as Nightwing in "Artifacts")
A young boy who Bruce Wayne takes in after his parents are killed by a gangster named "Tony Zucco". Bruce trains him in order to bring Dick into his crime fighting family, who adopts the moniker "Robin". Comes into the show in season 4, which differs from the comics as Batgirl had already been a part of Batman's team by that point.
Parental Obliviousness: The poor guy can never fully connect with his daughter due to clashing views, and even years into the future, he still doesn't know about her superhero double-life. Justified, as the only time he ever got a good luck at Batgirl was the first time he met her, and he was missing his glasses.
Remember the New Guy: Aside from the Early-Bird Cameo, Gordon's this. Alfred comments that "James Gordon has loomed large over [Bruce's] life." Then at the newly-installed Batsignal, Gordon says to Batman, "Thanks to all of your efforts, Batman, the time is finally right to take our alliance to the next step." Both said despite the fact that prior to "Night and the City," Gordon hadn't appeared in the present day.
Brother Chuck: Aside from a reference in "Artifacts", where it's stated she replaced Gordon as commissioner in the future, she's not seen or heard from again after Season 2, though she does appear on occasions in "The Batman Strikes" comic.
Damsel in Distress: Gets rescued by Batman more than once after the first season. In "Strange Minds", the Joker kidnaps her and nearly blows her up. Though she at least tries to fight Joker, he takes her by surprise and wins due to that.
Enemy Mine: Pulls one with Batman to defeat Man-Bat.
Expy: Is more or less the counterpart of Renee Montoya. Which is a bit funny because Renee Montoya originated in B:TAS and became a Canon Immigrant.
Adaptational Villainy/ Took a Level in Jerkass: Montoya was a supporter of the Batman from the start and was a nice reasonable cop who helped him take down criminals. However Ellen was an enemy of Batman and tries to capture the vigilante several times. She was also a cold and dismissive cop who enforces the law regardless of morals and gets called out by Ethan for it. While Montoya is grateful of Batman's heroic acts that saved Gotham from criminals, Yin continues to act like a bitch towards him. Fortunately, she pulls a Heel-Face Turn and becomes Batman's ally in season two.
She also heavily resembles Elisa Maza transposed into the Batman universe. She even wears the same outfit. Interestingly, Greg Weisman also wrote a handful of episodes for the series.
Genre Savvy: In "Traction" , she notifies all police officers to station at every hospital and to be on a lookout for a newly arrived patient with multiple wounds and fractures, knowing that if she finds the patient she would find Batman. She would have likely capture Batman if it weren't for Alfred.
Heel-Face Turn: Comes to realize that the Batman is not a menace and becomes his ally in Season 2.
Weaksauce Weakness: His ring has problems with the color yellow, something both Sinestro and the Joining exploit. Batman has backup plans in case the Justice League go rogue and Batman also would have no problem exploiting this weakness. It ends up helping beat the Joining, when they steal the Justice League's powers.
Follow the Leader: Lampshaded during the first time he teams up with Batman. Ollie mentions being inspired by Bruce's stuff at the end of the adventure. His appearance in the finale has him using the Arrowplane.
Everyone Calls Him Barkeep: He was never addressed by his real name, but the fact he comments about fighting criminals on two worlds and the comment about the Batcave resembling Thanagar Police Headquarters pretty much confirm he's Katar Hol.
Adaptational Badass: He is actually quite good in a hand-to-hand fight compared to his original incarnation. Though his direct fighting traits get somewhat minimized as the series progressed, and this was actually a very contentious depiction.
Asshole Victim: As with Rojas, he almost became one. And by the same person (Ethan Bennett/Clayface I), no less. And like Rojas, he deserved Ethan's enmity towards him, basically being the one who more or less made him Clayface.
Ax-Crazy: As is standard of the Joker. His first appearance shows him breaking into an asylum for the criminally insane and releasing the inmates, then trying to dose the entire town with his "Joker Gas" simply For the Evulz.
Bad Boss: Doesn't really treat Punch and Judy, his two most recurring henchmen, that nicely and even leaves them to get arrested so he won't miss his favorite TV show.
Does Not Like Shoes: As part of his feral characterization, he really doesn't like it. Even in later appearances where he starts acting more like his prior cartoon depiction, he still doesn't usually wear shoes.
Evil Laugh: Perhaps one of the most distinctive ones yet.
Faux Affably Evil: No matter how affable he can sometimes feign being, he's truly an evil man.
Fighting Clown: Literally; more so than any Joker before him, this Joker is clearly a trained fighter, seemingly using Monkey-style kung fu — lots of flipping, rolling around, leaping back and forth, and sudden, unpredictable strikes. Because of the divided reaction this elicited, this trait got dialed back in subsequent appearance, especially after the first season.
Maniac Monkeys: Has a very "feral ape" motif in his earliest appearances, especially the first episode. He climbs and clambers all over the place, uses his feet and hands interchangeably, monkey-like fighting style, he even tends to adopt a Primal Stance. He's very reminiscent of a crazy Tarzan in clown makeup.
Mad Artist: Carries shades of this, depending on the episode - in "The Rubberface of Comedy", for instance, he uses his "Joker Putty" to re-sculpt his own face onto a statue, and even wears a beret during the process!
Mind Rape: Does this to an already under stress Ethan Bennett.
Monster Clown: Arguably more monster than clown, with his very "feral" portrayal — Primal Stance, ape-like fighting style, perpetually bare and ambidextrous feet — though this turned a lot of fans of the older series off of him.
Adaptational Wimp: Yet, at the same time, he gives off a Harmless Villain impression far more often than other versions. More than once, his schemes only work out of convenience (the sonic device happens to work on Man-Bat; stumbling upon Green Lantern's ring, etc.)
Adaptational Badass: By his appearance in "Riddler's Revenge", he can actually last more than a few seconds in an outright brawl with Batman, which is more than most other incarnations of Riddler can say for themselves.
Batman Gambit: In his debut episode, he set fake bombs all over the city that could only be deactivated by solving various puzzles. This was actually a diversion made so that he could break into the City Hall database undetected and steal important information. He almost got away with it too.
In his first encounter with Batman, his scheme to discover his secret identity would have actually gone off smoothly and without a hitch... had he put a gag on Detective Yin. Her being able to freely talk distracted him enough for Batman to foil him.
Jerk with a Heart of Jerk: Is a user who often takes advantage of people's attempts to help her. Even before her turn to supervillainy, she tended to respond to heartfelt moments and opportunities for redemption with even more self-centered behavior.
Ungrateful Bastard: Best shown when Barbara attempts to talk her out of her scheme with Temblor. When Barbara points out that hiring a mercenary with money she doesn't have is way over her head, her response is to ignore her and casually indicate that their friendship is over. Then, when Barbara's warning turns out to be correct and the merc comes for revenge, Barbara tries to help her out of it anyways... and Pam abandons her, leaving Barbara to be killed by Temblor to buy herself some time.
Beast and Beauty: In an issue of The Batman Strikes, Croc falls in love with a news reporter, in part because she's the only person who refers to him as a man and not a monster. In the end, it turns out she rather likes him too, and he gives himself up to the police for her.
Beast Man: Possibly Croc's most beastlike incarnation to date. Thankfully, the writers didn't claim that he had a "skin condition" this time.
Multiple Choice Past: We don't know whether he's a military genetic experiment gone awry, he deals with the wrong kind of voodoo magic in the swamps, or if he's simply a circus freak.
If the tie-in comic, The Batman Strikes counts as All In The Manual, then according to issue 25, he was both a military genetic experiment subject before escaping, then was part of a circus freakshow before escaping that and ultimately coming to Gotham, though it's still unknown if he was born like that as in the comics or if being part an experiment is the reason for his appearance.
Never My Fault: Upon running into the homeless man who disrupted his escape so many years ago (thus setting off the chain of events leading to his immersion in the cryogenic chemicals), he goes out of his way to flash-freeze the man.
Elemental Shapeshifter: As has become the "norm" for the Clayface character. His body is comprised of something molecularly identical to clay, letting him reshape himself into any form he wants.
Enemy Mine: He tries to help Batman take down the Joker when he resurfaces, but Batman won't let him out of concern for his mental health. When the second Clayface appears, Batman and Robin willingly let him help them take the new guy down.
Expy: Is more or less the counterpart of Crispus Allen.
Also, he is Harvey Dent/Two-Face. From the long friendship with Bruce right down to calling Batman "Bats," a la Harvey from The Long Halloween.
Heel-Face Revolving Door: Starts out on the Face side, goes into the Heel side briefly, makes another attempt on the Face side briefly, slips back into the Heel side, then in Season 4 ended up back of the Face side and stays there.
How Do I Shot Web?: At first: it doesn't take long for him to get dangerously good with his powers.
Scooby-Doo Hoax: Impersonates Solomon Grundy during "Grundy's Night", when the villain is nothing more than folklore in the series' continuity. However, Grundy is implied to be Real After All.
That Man Is Dead: He tells Batman and Ellen to say goodbye to Ethan Bennet after his first shot at returning to a normal life. Subverted when he manages a Heel-Face Turn later anyway.
Token Good Teammate: Before his Face-Heel Turn, he was the only cop who supported Batman and believed that Gotham needs him. Ethan also was grateful of Batman rescuing his life and taking down criminals. On the flip side, Rojas and Yin remain ungrateful of Batman's actions and still antagonize him, even trying to unmask Batman at one point to which Ethan calls out on. In one early episode, he allows Batman to fight Bane without police interference, knowing that Rojas' officers would still be unappreciate his efforts.
Attention Whore: Not only doesn't he even try to hide from security cameras, he'll look into them and boast about what he's going to do. He also went on a news program and tried to tell a bogus sob story. In fact, aside from a brief instant when he felt some regret after attacking some people for rejecting him for an acting job, he embraces it after realizing he's famous because of it now and got angry when Batman was mentioned in the aforementioned news program.
Bad Bad Acting: He wasn't a good actor before he became Clayface and he still sucks at it when he gets his powers.
Dark and Troubled Past: Subverted as he doesn't really seem to have one and parodied it as he tried to tell a story where he and his sister had to fend for themselves, but the reporter he tells it to clearly wasn't buying it.
Elemental Shapeshifter: More powerful than Ethan Bennet, attributed in-universe to his taking a larger dose of mutagen.
Berserk Button: Not only was she upset that she got fired and her show canceled and a new show takes over her time slot, but the psychiatrist of that show plans to talk about how Harley's emotional breakdown after being fired led to a life of crime and that she was a lousy psychiatrist to begin with.
Dumb Blonde: What everyone thinks of her. She got an online degree in psychology to show everyone she's more than just a pretty face, but apparently no one could get past it. Her rage at this is what initially drives her to join the Joker.
Genki Girl: Though less humorous than in Batman: TAS and more dangerously psychotic like in the comics.
Jumping Off the Slippery Slope: It started with merely following the Joker home to grill him for info for a tell-all book. Then he convinced her to join him on a "night on the town," supposedly to help her research. By the end of it, she had gleefully taken part in a spree of destruction and was willingly trying to attack Batman. And when the media catches wind of this and makes her a pariah for it, she really goes off the deep end.
Mad Love: Naturally, though it's played a little different than usual. Here, Joker dotes on Harley and legitimately seems to enjoy her company as opposed to his usual abusive fare, but sees the whole thing as mere entertainment and doesn't really care about her any more than that. Likewise, though he still manipulates her into the whole thing, it's made clear that this version of Harley really enjoys the whole supervillain lifestyle and helps him for reasons more than her usual delusional Extrme Doormat personality.
Role Reversal: The tie-in comic gives her her usual team-up with Poison Ivy, but switches the roles around: making Harley the (relatively speaking) level-headed brains of the operation, while Ivy is the unstable one. It helps that Ivy is an impulsive teenager in this continuity, while Harley - while still a totally daffy hedonist - is a bit more independent and cunning than usual.
Badass Boast: "I am Bane. The last opponent you will ever face."
Curb-Stomp Battle: Does this to Batman, though for different reasons than in Knightfall. Mostly the fact that using Venom turns Bane into a Hulk-like figure in this incarnation and that his debut was in the second episode of the whole series meant he was going up against a Batman still getting used to fighting supervillains and whose only prior experience at that point was the Joker.
The Spook: When the Gotham PD gets him in custody, they can find no matching fingerprints, no identifying marks, and they're unable to remove his mask. He also has quite a well trained organization for a guy with a completely unknown background.
Blessed with Suck: Arguably; the clones he creates become progressively more and more sentient, and every multiplication equals an even more untrustworthy clone. This ability only comes in handy a few times, so a long fight isn't exactly a good idea.
Generic Doomsday Villain: He may well be a deconstruction. He is a robot programmed by Dr. Hugo Strange with the memories and abilities of Batman's worst foes for the sole purpose of giving Batman a challenge. He proceeds to easily curbstomp Batman and steals ALL of Gotham's money just to commit the ultimate crime, but is defeated when Batman asks him to explain his origin story. Since D.A.V.E believed that he used to be a person, he basically went catatonic after realizing that he had no backstory of his own.
LEGO Genetics: He's made from the mental patterns of Batman's enemies.
