"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.
Actor Allusion: "The Big Dummy" sees Bruce putting off a date with a woman named Becky, voiced by Jennifer Hale. It isn't the first time a character voiced by Hale served as a love interest to a superhero voiced by Rino Romano, but in thoseothercases, they did hook up and actually had a relationship.
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.

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.
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.
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.
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.
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.)
The Beastmaster: Like several other portrayals, he commands a huge amount of trained birds that apparently have a taste for human flesh.
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.
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.
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.
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.
Voiced by: Joaquim de Almeida (in "Traction"), Ron Perlman (in "Team Penguin"), Clancy Brown (did Bane's grunts in "The Batman/Superman Story")
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.
The Dragon: To Hugo Strange, although he is unaware of this since he tends to act on his own accord.
Generic Doomsday Villain: Strange was more or less invoking this trope in-universe. He comes close to beating Batman in a single episode only to be defeated by Batman pointing this out. When challenged to explain his origin story, D.A.V.E "crashes".
