List of Batman Beyond characters
This is a list of characters found in Batman Beyond, part of the DC Animated Universe (DCAU) continuity.

Batman Beyond

Main characters
 Terry McGinnis (voiced by Will Friedle) - The current Batman and a former juvenile delinquent. Under the pretense of doing errands for Bruce, Terry fights crime as the new Batman. Terry was chosen to be the new Dark Knight as he shared a similar loss as Bruce had; that being the death of a parent.

 Bruce Wayne (voiced by Kevin Conroy) - The original Batman, he is Terry's employer, mentor, and predecessor and former CEO of Wayne Enterprises. During his final mission as Batman, Bruce suffered a heart attack that forced him to use a gun in self-defense. Abhorred by this, he hung up his cape and cowl. At some point, Wayne Enterprises merged with Powers Technology where Derek Powers took over Bruce's position as CEO. When Terry became the new Batman, Bruce monitors his activities from the Batcave. Following the presumed death of Derek Powers and the arrest of Paxton Powers, Bruce reassumed control of Wayne-Powers.

 Maxine "Max" Gibson (voiced by Cree Summer) - A genius high schooler and friend of Terry's. She discovers his secret identity early on in the series, and from then on occasionally helps Batman in an Alfred-like role, though she is considered a nuisance to his predecessor (but less so as time went on). Her parents are divorced and she has an unnamed older sister.

 Ace (vocal effects provided by Frank Welker) - Bruce Wayne's pet Great Dane, who was formerly a stray before being adopted by Bruce after he defended him from a Jokerz thug at Crime Alley during one of his annual visits there in memory of his slain parents. Fiercely loyal to Bruce and distrustful of Terry at first, he eventually develops an improving bond with Terry as the series progresses.

Terry's family
 Warren McGinnis and Mary McGinnis (voiced by Michael Gross and Teri Garr) - Terry and Matt's divorced parents. Warren was killed by Mr. Fixx at the start of the series. How that happened is unknown, nor revealed to the public. Terry moves in with his mother after his father's death. Mary believes that Terry works as an errand boy for Bruce. In the rebooted universe, Mary was killed during the Futures End crossover.

 Matt McGinnis (voiced by Ryan O'Donohue) - Terry's younger brother. Always looking to get his brother in trouble, Matt is ironically a big fan of Batman. In the rebooted universe, Matt finds out about Terry's secret and becomes an invaluable ally to Batman, as well as the new Robin.

Recurring characters
 Dana Tan (voiced by Lauren Tom) - Terry's girlfriend. She is Chinese American and had a hard time accepting his responsibilities as Bruce Wayne's employee initially, but became more understanding regarding his frequent absences. In both the original comics and the rebooted universe, she discovers Terry's secret. Later on, it is revealed during the Justice League Unlimited episode "Epilogue" that Terry was going to propose to her.

 Barbara Gordon (voiced by Stockard Channing in season 1, Angie Harmon in seasons 2 and 3 and Batman Beyond: Return of the Joker, Tara Strong as the young Barbara Gordon/Batgirl in Return of the Joker) - The no-nonsense Gotham police commissioner and former Batgirl. She was the daughter of the long-deceased former police commissioner James Gordon. No longer what she once was, having been hardened and determined through years of personal tragedy, the new Commissioner Gordon is not entertained by the notion of Batman's heir and often clashes with Terry, though time helps her to realize his value to Neo-Gotham. Unlike most Batman universes, she never lost the use of her legs or became Oracle, although the event that in the comics led her to become the latter was referenced in the episode "A Touch of Curaré". It is also implied that she had an affair with Bruce that ended badly. Due to Barbara's father's past alliance with Batman, she is being suspected by the city (especially his rogues gallery) of maintaining the same relationship with him despite that she did not reinstall the Bat-Signal. In the rebooted comic universe, Barbara's not against working alongside Terry, she also encourages Dick Grayson's daughter Elainna to continue as the new Batwoman.

 Melanie Walker (voiced by Olivia d'Abo) - A member of the Royal Flush Gang by the name of Ten, she is an on-off love interest of Terry McGinnis, similar to Bruce Wayne and Selina Kyle, but without Melanie knowing that Terry is Batman.

 Sam Young (voiced by Paul Winfield) - A Gotham district attorney and Barbara's husband.

 Howard Groote (voiced by Max Brooks) - A nerdy student at Hamilton Hill High School and friend of Terry. His design was based on producer Paul Dini.

 Bobbi "Blade" Sommer (voiced by Melissa Disney) - A popular student at Terry's school. She never has a steady boyfriend and occasionally goes out with different boys. Blade is seen to be friends with Terry, Dana, Max and Howard.

 Chelsea Cunningham (voiced by Yvette Lowental in earlier appearances, Rachael Leigh Cook in later appearances) - Another Hamilton High student, she is the best friend of Dana and Terry and the former girlfriend and crush of Nelson.

 Nelson Nash (voiced by Seth Green) - An athlete and bully at Terry's school, who eventually matures and becomes more friendly towards him during the series. He seems to be popular with the girls, but never has a steady girlfriend. He is very similar, both physically and mentally, to Flash Thompson from the Spider-Man universe, given his adversarial-turned-friendly relationship with Terry and his admiration for Batman.

Supporting characters
 Justice League Unlimited - The series' incarnation of the Justice League.
 Superman (voiced by Christopher McDonald) - Kal-El, the Last Son of Krypton and an old ally and friend of Bruce during the latter's time as Batman and with whom he founded the original Justice League. The Man of Steel is still dedicating his life to fight for truth and justice, both in his superhero persona and as journalist Clark Kent. In the rebooted universe, Superman is Clark's adult son Jonathan.
 Aquagirl (voiced by Jodi Benson) - An Atlantean princess and daughter of the now-missing Aquaman.
 Big Barda (voiced by Farrah Forke) - A former member of the Female Furies of Apokolips.
 Green Lantern (voiced by Lauren Tom) - An Asian boy, Kai-Ro, is the latest to be chosen by the Green Lantern Corps to protect Space Sector 2814.

 Warhawk (voiced by Peter Onorati) - Rex Stewart is the son of Green Lantern and Hawkgirl and successor of Hawkman.

 Infiltration Unit Zeta (voiced by Gary Cole in the first appearance, Diedrich Bader in later appearances) - An assassination android who unexpectedly develops a conscience and goes on the run as a fugitive from the government. Zeta became the protagonist of a spin-off series The Zeta Project.
 Rosalie "Ro" Rowan (voiced by Julie Nathanson) - A teenage runaway who joins Zeta in his quest for freedom.

Villains
 Derek Powers / Blight (voiced by Sherman Howard) - A ruthless businessman and father of Paxton Powers, whose company Powers Technology merged with Wayne Enterprises years before, around the time of Wayne's retirement as Batman where he had become the CEO of Wayne-Powers. After accidentally being exposed to his own nerve gas, Powers is treated with radiation. This transforms him into the supervillain known as Blight, who has a translucent skeletal appearance and power over radiation. His secret dual identity as Blight was later exposed by Paxton. In a fight with Batman on his submarine, Blight damages the vehicle and sinks alongside it where he is presumed dead.
  (voiced by George Takei) - Derek Powers' right-hand man who is responsible for Warren McGinnis' death under his employer's orders. Having lost his right eye in the past, it implied by the shape of his scar that the original Batman was responsible with one of his batarangs. Fixx is presumably killed in a plane crash after a battle with the new Batman, drowning in Powers' weapon supplies in Gotham Bay.
 Dr. Stephanie Lake (voiced by Linda Hamilton) - A Wayne-Powers scientist. While being among the scientists who work to suppress Powers' radiation, Dr. Stephanie Lake suggested building him a new body. To test out this process, Dr. Lake convinced the head of Mr. Freeze to go through the cloning process while transferring his mind into the clone. While the process with Mr. Freeze worked at first with Victor Fries making different types of amends in his new body, Dr. Lake found that Victor's body was starting to revert to his subzero biology. Victor escaped after Dr. Lake locked him in a hot room under Powers' orders so that they can study the problem. When Victor obtained a new suit to keep his body cold, he resumed his Mr. Freeze identity and confronted Powers and Dr. Lake, which resulted in Mr. Freeze using his freeze gun to freeze Dr. Lake to death. Powers was also frozen, but was thawed out when he became Blight.
  (voiced by Cary Elwes in "Ascension", Parker Stevenson in "King's Ransom") - The estranged son of Derek Powers who takes over his position as Wayne-Powers CEO after he secretly arranges the public exposure that reveals the elder Powers' identity as the supervillain Blight. However, Paxton is also as ruthless and power-hungry as his father's. Unlike his father, Paxton neglects his duties as CEO and squanders the company's money for his leisure, causing numerous scandals to his own public and professional lives in addition to ones by his father as Blight. Eventually after numerous schemes opposed by Batman, Powers was arrested after his collusion with the Royal Flush Gang was exposed and Bruce Wayne re-assumed control of his company.

 The  - A violent street gang who dress and act in the tradition of the infamous Joker. Unlike the supervillain they emulate, they are merely teenage delinquents who enjoy vandalism and petty crime. They are usually apprehended by Batman quite easily and serve as more of a nuisance than a genuine threat. Despite this, they are a genuine problem for Neo-Gotham, and their criminal activities and constant harassment of innocent citizens are one of the first signs that show how much worse things have gotten for the city after the original Batman's retirement. There have been three different versions of the Jokerz. In the mainstream comics, Dick Grayson (who was operating as Batman at the time) encountered a gang called the Jokerz which is led by a man impersonating the real Joker.
 J-Man's Jokerz Faction - The first faction of the Jokerz are first seen in the series premiere "Rebirth". They are seen committing petty pranks and harassment before being framed by Mr. Fixx for the murder of Terry's father. This branch of the Jokerz has appeared throughout the series since.
 J-Man (voiced by Bruce Timm) - Dresses very similarly to the original Joker. Bruce Timm is a producer for the DCAU shows, and joked in the DVD commentary that his performance as J-Man was "Emmy-Award-winning material".
 Dottie (voiced by Lauren Tom in the first appearance, Cree Summer in later appearances) - A member of the Jokerz who wears a polka-dot dress, and wields a spiked rubber chicken.
 Smirk (voiced by Michael Rosenbaum) - J-Man's "right-hand clown".
 Coe (voiced by Scott Valentine) - A member of the Jokerz who wears a jester's hat and a jacket with one of the sleeves ripped off. He wields a baseball bat.
 Spike (voiced by Joe Lala in the first appearance, Mark Slaughter in later appearances) - A member of the Jokerz who wears a green trenchcoat and carries an acid-laced cream pie with him.
 Scab (voiced by Marc Worden) - A member of the Jokerz that wears a red single-coned jester's cap. He is a power-hungry psychopath and wears a giant boxing glove on his right hand.
 Top Hat (voiced by Bruce Timm) - A member of the Jokerz that wears an outfit similar to the DCAU version of the Penguin.
 Lee (voiced by Ethan Embry) - A student at Hamilton Hill High School, who dropped out to join the Jokerz. When Scab and Coe stole an experimental aircraft during his initiation, he began to doubt being a  member of the Jokerz. After Batman defeated the Jokerz, Lee left the group, choosing to lead a decent life.
 Terminal's Jokerz Faction - The second faction of the Jokerz was introduced in the episode "Hidden Agenda", shown committing more violent and arsonist acts than the first group.
 Carter Wilson / Terminal (voiced by Michael Rosenbaum) - A popular and genius student at Hamilton Hill High School who was obsessed with being the best at everything he did. He led the second group of Jokerz in an attempt to kill Maxine Gibson, who had scored higher on an important test than he had, and was going to be voted Class Valedictorian instead of him. Terminal's vendetta against Max and the subsequent intervention by Batman led to Max's realization of Terry's secret identity. Terminal later appears in the rebooted universe trying to revive a dying Bruce Wayne to gain access to his Keytone data network. He disguises Bruce as the Joker to gain influence and control over the Jokerz. Terminal is later killed by the real Joker, who had been aiding him in his scheme.
 Trey (voiced by Omar Gooding) - Terminal's "right-hand clown". He dropped out of school in the 6th grade to join the Jokerz. He used to be a member of J-Man's gang, but eventually joined Terminal's gang.
 Tayko (voiced by Cree Summer) - A member of Terminal's branch of the Jokerz who is an amazing gymnast.
 Weasel (voiced by Will Friedle) - A member of Terminal's branch. Known for his high-pitched holler, Weasel carries a flail around and has many other weapons in his jacket. He used to be a member of J-Man's branch of the Jokerz, but joined Terminal's branch later on.
 The Third Jokerz Faction - The third faction of the Jokerz was introduced in Batman Beyond: Return of the Joker where they worked for what appeared to be the Joker himself. They later reappeared in the Justice League Unlimited episode "The Once and Future Thing, Part Two: Time, Warped", now working for Chronos and enhanced with superpowers. When Chronos was defeated, this timeline was erased.
 Bonk (voiced by Henry Rollins in Batman Beyond: Return of the Joker, Adam Baldwin in Justice League Unlimited) - A powerful, but surly enforcer/muscleman in the Jokerz' ranks. Though amazingly strong, Bonk is not a thug who takes orders willingly. He has a hair-trigger temper and is liable to start up with anyone who gets in his way, be it Batman or Bonk's own Jokerz allies. This is his undoing when he argues with the Joker, accusing him of being a fake. In return, the Joker murders him either with a venomous spear gun disguised as a flag gun, or with laughing gas (depending on the unedited or edited version of the film). In Justice League Unlimited, he is equipped with a massive hammer that comes out of his arm.
 Chucko (voiced by Don Harvey) - Obese with tight-fitting pink clothes and a clown mask, he is a nasty bullying type who truly enjoys inflicting misery on others. A head enforcer for the Jokerz, he is a lot stronger and faster than his flabby gut would lead one to believe, and wields a bazooka. An alternate-timeline version of Chucko appears in the Justice League Unlimited episode "The Once and Future Thing", wielding a laser sword and having a hovering ball in place of legs. He betrays Chronos by tipping off the Justice League Unlimited and is sent back to the Mesozoic during the extinction of the dinosaurs. This incident serves as a warning to the other members of the Jokerz.
 Dee Dee (both voiced by Melissa Joan Hart) - The identical twin granddaughters of Harley Quinn. Delia and Deidre Dennis (often referred to by the collective name "Dee Dee" or simply, "the Deeds") are cute, charming, funny, and completely rotten to the core. They love the thrill of being part of the Jokerz and think it is a large charge to be working for the big man himself, the Joker. They use an acrobatics-based fighting style very similar to both Harley and Nightwing's. They fight in unison, acting almost like one person controlling two bodies, even finishing each other's sentences. They are imprisoned at the end of Batman Beyond: Return of the Joker, but bailed out by their grandmother, the former Harley Quinn, whom they refer to as "Nana Harley". They appear in the Justice League Unlimited episode "The Once and Future Thing", wielding electric whips and having the ability to duplicate themselves.
 Ghoul (voiced by Michael Rosenbaum) - He wears ragged clothing and has grey skin with stitch-like marks and skull-like features, somewhat resembling previous Batman nemesis the Scarecrow. A jaded young runaway from a wealthy home, Ghoul joined up with the Jokerz for kicks. He is heavily into techno-Goth music and has adapted the horror look into his costume. Ghoul is never without his plastic Halloween pumpkin, which he keeps filled with a number of monster-inspired weapons and tricks. Ghoul eventually returned in the Justice League Unlimited episode "The Once and Future Thing", wielding a retractable spinning blade in his right arm.
 Woof (vocal effects provided by Frank Welker in Batman Beyond: Return of the Joker, Dee Bradley Baker in Justice League Unlimited) - A Jokerz thug spliced with a spotted hyena. Though he sometimes appears to be nothing more than a comical mascot, Woof's crushing jaws and razor-like claws make him a deadly adversary. He also appears in the Justice League Unlimited episode "The Once and Future Thing", being armed with powerful cybernetic arms.

  (voiced by Shannon Kenny) - A freelance criminal who gained shapeshifting abilities from a mutagenic treatment, being able to become black, ink-like liquid. She is shown to be vulnerable to immersion in water (which can disperse her substance and hampers her ability to re-form) and freezing temperatures, the latter of which is how she is kept imprisoned after being apprehended. In the Justice League Unlimited episode "Epilogue", Inque appeared as a member of the Iniquity Collective where they fought the Justice League Unlimited. She is based on Clayface. She has a daughter named Deanna Clay (voiced by Azura Skye) from whom she is estranged.

  (voiced by Scott McAfee) - A nerdy student at Hamilton Hill High School who was constantly picked on by bullies at school, has unrequited feelings for Bobbi, and forced to deal with his overbearing father at home. Seeking revenge, he stole a mentally-controlled robot called the GoLeM (Galvanized Lifting Machine) from his father's construction company and used it to attack his tormentors, but the machine was destroyed by Batman and he was sent to juvenile detention for three years. However, his experience with the GoLeM caused him to develop powerful telekinesis, which he uses to bring terror to his fellow detainees and secretly leave and return to the facility at will. He attempted revenge on his schoolmates again by using his powers to convince everyone that the school was haunted. Despite having been defeated by Batman once more, Willie's powers remain active. He is also somewhat friendly to Terry McGinnis since he was not one of his tormentors; not knowing that Terry and his enemy, Batman, are one and the same.

 Victor Fries / Mr. Freeze (voiced by Michael Ansara) - The tragic villain lives on as an immortal head preserved by Derek Powers. He was used as a test subject in an attempt to clone a new body for Powers. Mr. Freeze's baseline DNA was used to create a new body where his mind was transferred into it. In his new body, Victor Fries started to make a lot of amends. However, Freeze's new body begins to suffer the same symptoms as his previous body like wanting to exist in cold temperatures. After Powers' scientist Dr. Stephanie Lake tries to eliminate Freeze to study the problem, he obtains a new advanced suit that was kept in "cold storage" and planned revenge where he froze Dr. Lake to death, leading to a final battle with Derek Powers' alter ego Blight and Batman as well. Driven past the breaking point by losing his life a second time while having been badly injured by Blight, Freeze finally committed suicide by overloading a reactor and sealing off the building, despite Batman trying to help him and having blasted Blight out of the compound. Mr. Freeze died in the ensuing explosion.

  - A group of scientists tragically transformed into superpowered beings during an apparent lab accident. At first, they tried to use their powers for the benefit of society, but their conditions slowly drove them into insanity. When they discovered that their mutations were irreversible and the accident had been set up by one of their co-workers Dr. Hodges, they set out to get revenge and to recreate their circumstances  to produce more of their kind. In the attempt, they were defeated by Batman, who trapped the 2-D Man and Freon in a ventilation system and used a water hose on Magma. The Terrific Trio are based on the criminal gang the Terrible Trio and the Marvel Comics superhero team the Fantastic Four.
 Dr. Mike Morgan / Magma (voiced by Robert Davi) - A hulking magma-like monster.
 Mary Michaels / Freon (voiced by Laura San Giacomo) - A gaseous woman with ice-like powers. In the rebooted universe, Doctor Hodges resurrects Freon at the cost of his life. Freon attempts to get revenge on Neo-Gotham by turning the city's defense system against itself, but she is stopped by Batman, Shriek, and Hacker.
 Stewart Lowe / the 2-D Man (voiced by Jeff Bennett) - A flat individual with stretching capabilities.

 Walter Shreeve /  (voiced by Chris Mulkey) - Walter Shreeve is initially a sound engineer hoping to improve society with his inventions. He is led down a decidedly darker path by Derek Powers, who wants a return on his investment in Shreeve's research. Powers thus dubs him "Shriek" based on his special suit, which allows him to generate destructive sound waves and manipulate sound in a wide variety of ways. He also created "the Fork", a tuning fork-like device that stimulates the pleasure centers of the brain. During a fight with Batman, his suit is damaged, causing it to pick up sounds at such a high volume that Shreeve is rendered permanently deaf. Though he develops a special headset to hear normally, the incident drives him insane and vengeful against Batman, returning several times using his technology to seek revenge against him. Shriek later makes a cameo appearance in the Justice League Unlimited episode "Epilogue" as a member of the Iniquity Collective, where they were defeated by the Justice League Unlimited. In the rebooted universe, Shriek escapes from prison after Brother Eye's conquest of the world and becomes the self-appointed protector of the people who still live in the tunnels.
 Ollie (voiced by Michael Rosenbaum) - A splicer of indeterminate species who serves as Shriek's henchman and main ally.

 Charlie "" Bigelow (voiced by Stephen Baldwin in the first appearance, Clancy Brown in the second appearance) - A loudmouth hoodlum and former friend of Terry McGinnis. Three years prior to Terry becoming Batman, Charlie and Terry were arrested for burglary. Charlie was old enough to be tried as an adult and was sentenced to three years in prison. Terry avoided prison because he was underage at the time and Terry's early life of petty crime was largely the result of Charlie's negative influence. Charlie attempts to reconnect with Terry after he is released, but is rebuffed due to his continuing criminal behavior. Charlie later becomes involved with a gang of thieves-for-hire who plan to rob a Wayne-Powers research lab to steal an experimental chemical for a rival company. During the robbery, Terry (as Batman) intervenes. Charlie is exposed to the chemical during the fight and later mutates into a deformed super-strong being. This event leaves Terry wracked with guilt. Big Time later returns in “Betrayal”, trying to take over the Neo-Gotham underworld and kidnapping Terry so he could join him. Big Time apparently falls to his death into the harbor during a fight with Batman at the end of the episode.

 Richard "Richie" Armacost (voiced by Robert Patrick) - A top executive at the agricultural company Agri-Chem who was jailed for insider trading. He met and befriended Big Time while in prison and talked him into a job.
 Karros (voiced by William H. Macy) - A mercenary and high-tech specialist employed by Agri-Chem.

 Melanie Walker as Ten (voiced by Olivia d'Abo) - See above.
 Jack Walker as Jack (voiced by Scott Cleverdon in the first appearance, Nicholas Guest in later appearances) - Son of Mr. and Mrs. Walker.
 Ace - An android who serves as their bodyguard.

 Bane: In the years since Bruce Wayne's retirement from crimefighting, Bane's constant use of the super-steroid Venom has destroyed his body, leaving him a withered husk of a man kept alive by the very drug that once gave him superhuman strength.
  (voiced by Larry Drake) - Bane's personal attendant, who mass-produced and sold Venom-laced patches called "slappers" to teenagers. During a battle with Batman, Chappell overdoses on the slappers, which puts him into a coma.

 Ira Billings / Spellbinder (voiced by Jon Cypher) - A bitter and underpaid psychologist at Terry's high school who commits crimes using sophisticated virtual reality systems and his knowledge of the human mind. After his first arrest, his life is ruined as the result of his exposure as a supervillain and he blames Batman for it, then seeks revenge. In the rebooted universe, the Spellbinder brainwashes Terry after the latter's supposed death into becoming the new Rewire, while Tim Drake becomes the new Batman Beyond. He is eventually defeated by Drake.

 The Society of Assassins - A secret group of assassins.
 The Master Assassin (voiced by Victor Rivers) - A man named Devon is the head of the Society of Assassins.
  (voice effects provided by Melissa Disney) - A member of the Society of Assassins, who wields a laser-sharpened scimitar that can cut through any material and never speaks. Her true identity was never revealed and Batman had once glimpsed her feature when her veil fell during a fight. He was visibly shocked and this implied that she is terribly disfigured. After Batman foils her attempt to assassinate Gotham's District Attorney, she ends up becoming a target of the Society herself, resulting in Curaré ultimately killing every member of the Society of Assassins before seeking revenge against Batman. In the rebooted universe, Curaré arrives in Gotham to warn Batman about the League of Assassins' plans under the leadership of the new Ra's al Ghul.
 Mutro Botha (voiced by Tim Curry) - The last surviving member of the Society of Assassins, who tries to blackmail Batman into protecting him from Curaré.

  (voiced by Ian Buchanan) - A doctor who starts a trend in infusing animal biology with human DNA known as "Splicing". Using his research to commit crimes before ending up on the wanted list, Cuvier later used a vampire bat serum on Batman and later goes into hiding with his minions following a botched attack on Sam Young. When Batman tracked them to the abandoned Carmine's Taxidermy Studio, Cuvier later mutates himself into a genetic chimera with hawk, snake, and tiger traits to battle Batman following his minions' defeat and depowerment. He ends up getting a massive overdose that further mutates him into a monster and apparently dies when he accidentally ignites several gas tanks, causing a massive explosion. Though the technology of splicing becomes outlawed shortly after Cuvier's presumed death, it continues to surface as an illegal subculture throughout the series as seen in later episodes. In the two-part episode "Curse of the Kobra", it is hinted that he is a member of Kobra as a younger version of him was seen with Zander and Dr. Childes. Cuvier appeared in the comic book spin-off, having survived the incident, and appeared in issue #3 of the second volume, where he reverted to his original hybrid form with a plan to splice animals with human DNA. In the rebooted universe, he is one of Brother Eye's allies under the name of "The Doctor" and battles Tim Drake.

 Robert Vance (voiced by Stacy Keach) - After uploading his mind into his company's computer systems before his death, Robert Vance plans to resurrect himself by downloading his virtual consciousness into the body of one of his descendants. His consciousness is deleted and his mind regresses into nothing in a manner similar to HAL 9000 from the film 2001: A Space Odyssey.

  (voiced by Carl Lumbly) - An African hunter wanted on three continents who was enhanced with cybernetic implants after an encounter with a black panther that broke his spine. These implants enhanced the Stalker's strength, speed, and reflexes, which he used  to take revenge on the black panther. Afterwards, finding wild animals too easy to hunt, Stalker seeks Batman as the ultimate prey and proves to be one of his more difficult opponents. While the Stalker was thought dead upon being struck by a train after Batman electrocuted his cybernetics, he would later turn up alive when the NSA found him. The Stalker was later used by Agent Bennett to work with Batman in hunting Falseface. In the Justice League Unlimited episode "Epilogue", the Stalker appears as a member of the Iniquity Collective where they fought the Justice League Unlimited. In the rebooted universe, the Stalker was hired by Payback to capture Batman, only doing so because his village was on the brink of extinction thanks to Brother Eye's attacks. After aiding Batman in his fight against Payback, Terry brings Wayne Enterprises resources to the Stalker's village to save his people.

It is noted that many people had a tendency to call him Ratboy because of his strange appearance. He develops an obsession with Dana, frequently sending her love letters and gifts. He later kidnaps Dana, taking her to his home in the sewers and confessing his love for her, but she rebuffs him and he angrily commands an army of rats to kill her.

After losing his job to Paxton Powers, Jim builds an arsenal of advanced weapons and armor and becomes the supervillain Armory to make ends meet for his family, but is later thwarted by Batman. Armory later realizes the error of his ways and assists Batman in defeating Istivan Hegedesh before he is apparently sent to jail, although it is implied that his heroic actions will lead to a reduced sentence.

 Istivan Hegedesh (voiced by Corey Burton) - A weapons designer at ForceTech and old friend of Jim Tate. ForceTech would later be revealed to be behind some sales to a shady country that is under a weapons embargo. When Hegedesh and the rest of Jim's family find out about Jim's workshop, Hegedesh ran afoul of Batman and used a sonic weapon to subdue him before being foiled by Jim. This enabled Batman to defeat Hegedesh, who was arrested afterwards.

 Joker King - Dana Tan's troubled brother who worships the Joker and desires to follow in his footsteps. Doug Tan becomes a leader of the Jokerz, calling himself the Joker King and leading the Jokerz to cause chaos in Neo-Gotham City.

After the battle with Batman and his allies, the Joker King's reign of terror ends when his foot is caught by some rope and he falls off the ledge. The swing from the rope causes Doug's body to slam against the concrete wall of an unfinished building. The trauma inflicted to Doug's head kills him instantly. His liver is donated by his family to Bruce Wayne, who was dying at the time and in need of a transplant.

 Rebel One - The secret leader of hacker collective Undercloud. She grew up on Level 2 of Neo-Gotham and resented the people that lived in the higher levels.

He deceives his doctors into thinking his therapy worked while actually planning the murder of his father by disrupting his pacemaker through a telephone.  His powers are amplified by a mixture of Venom and Joker venom created by Ghoul. Davis is eventually brought down by a containment device that regulates the electrical impulses that his father had built before his death. In the rebooted universe, the Spellbinder brainwashes Terry into believing he is Davis Dusk and the new Rewire.

 Man-Bat - After the original Batman helped rescue his wife Francine from her own Man-Bat metamorphosis (see the Batman: The Animated Series episode "Terror in the Sky"), Kirk Langstrom had vowed to never again take the serum that had nearly destroyed his life.

Kirk somehow also discovered that Bruce Wayne was Batman years ago when he funded Kirk's sonic research. Though both Kirk and Francine were happily married for years and eventually had a son and a daughter named Max and Michelle, Francine eventually begins to suffer from Parkinson's disease and Kirk's relationship with his children begins to deteriorate.

Other characters in the comic book adaptions
 Dr. Nora Reid ( Elliot) - A granddaughter of the apparently-deceased Thomas Elliot, geneticist Doctor Nora Elliot-Reid seeks to amend her paternal grandfather's sins as the criminal mastermind Hush by working for Amanda Waller. Reid inadvertently created a successor who would carry on his legacy by cloning one of the original Batman's partners. It is believed that her grandfather died as Hush after his last battle with the original Dark Knight Detective. However, despite the official police report confirming the body's identity, Elliot's reputation as a master tactician and skilled surgeon had left his enemies in doubt of whether it really belonged to the villain.  Because of the Elliot family's history of depravity and deception, many also doubt whether Doctor Reid is really as decent as she seems to be.

 Undercloud - A collective of internet users who blackmail Max Gibson into joining. Undercloud is a loose collective of over 1,000 hackers, operating 'in the dark' so that no one member can endanger the entire collective.

 Vigilante -  is a great-grandnephew of Joe Chill, the mugger who murdered Thomas and Martha Wayne. Chill is also a former security guard of Wayne-Powers who worked under Derek Powers' right-hand-man Mr. Fixx. His employment by Powers had led Chill down the same path as his great-granduncle's: by killing Warren McGinnis under Mr. Fixx's orders, leaving him wracked with guilt towards the McGinnises and repeating history again by indirectly creating a Batman. After Bruce Wayne reclaimed his family's company, he fired Chill after he had been discovered to have worked at Powers' "Quiet Squad", aware of Chill's relation to his parents' killer and his possible involvement in Warren McGinnis' murder. His termination also drove Chill towards poverty. Seeing Batman as an inspiration, Chill sets to become a vigilante himself to atone for his family's sins. He called himself Vigilante and worked with Batman to stop a Jokerz riot led by Doug Tan. He is eventually killed by the Jokerz and the Phantasm (who was sent to kill him by Waller to prevent Batman from doing so after Terry discovered his identity). His death led to Terry ending his partnership with Bruce, as Bruce did not inform Terry about Chill's past.

 The Hacker - In the rebooted universe, Bo Han was a young technological genius who gained the ability to hack nearly any technology with his hands during Brother Eye's invasion. He becomes a new vigilante known as the Hacker and protects the Chinatown district of Neo-Gotham.

Justice Lords
In the parallel universe where the Justice Lords reside, the original Lord Batman has long died after fighting Lord Superman, Lady Wonder Woman, and their tyrannical followers. His absence affected those who were closest to him and, in addition, those who would have been if he was still alive:

 Terrance "T" McGinnis (Justice Lords) - Terrence "T" McGinnis is in a relationship with the former Royal Flush Gang member Ten (Melanie Walker), and without Bruce Wayne's guidance, he remains a delinquent and is a member of the Jokerz alongside his lover. After T. meets his heroic counterpart, he begins to question his purpose in life. After the Justice Lords' defeat, T. is inspired to become the new Batman, with Dick Grayson as his mentor. Unlike his counterpart, T. is not driven by the tragic death of his father (which never occurred in this world), but by Lord Superman's unjust actions.

 Mary McGinnis (Justice Lords) - Suffering former wife of Warren McGinnis and mother of T. McGinnis.

 Dick Grayson (Justice Lords) - Like his counterpart, Grayson also served as Lord Batman's partner as Robin and later Nightwing. However, due to the Joker being lobotomized by Lord Superman years before, Grayson never sustained an injury resulting in the loss of an eye, as did his counterpart. In turn, his successor Tim Drake never gave up being Robin and went on to become Red Robin until Lord Batman's death forced both Grayson and Drake to retire from superheroics. In addition, Grayson married Barbara Gordon and worked as a high-ranking officer to the Justice Lords' task force. However, Dick did not allow Gotham to completely descend into a totalitarian state like the rest of the world. Terry McGinnis' arrival inspired Grayson to continue his late mentor's mission and to groom McGinnis' counterpart into the new Batman.

 Barbara Gordon (Justice Lords) - Wife of Dick Grayson. Like her husband, Barbara also previously served as Lord Batman's partner as Batgirl, but unlike her counterpart, Barbara was never romantically involved with Bruce Wayne (who was happily married to Wonder Woman prior to his death), and thus never indirectly caused the disintegration between Dick's bond with his mentor. She and Dick are happily married and have a son.

 John Grayson II - Young son of Dick Grayson and Barbara Gordon. Learning of John's existence makes the mainstream universe's Dick Grayson envy the life his counterpart leads with his wife and he becomes more bitter towards Bruce, who indirectly caused the disintegration of his relationship with Barbara.

 Warren McGinnis (Justice Lords) - Suffering former husband of Mary McGinnis and father of T. McGinnis.

 Zod - Genetically engineered son of Lord Superman and Lady Wonder Woman who joins the Justice League as the youngest member and under the tutelage of his father's benevolent counterpart, Superman.
