Founding Members
The initial six main characters were chosen by the producers, from a list of potential candidates of 50 to 60 DC Comics teenage superheroes.[1] The criteria consisted of age, powers, personality, cultural icon status, and dynamics.[2] An additional regular, Zatanna, was introduced partway through the first season, and Rocket was added at the end of the first season.[1]
- Nightwing / Robin I / Dick Grayson (voiced by Jesse McCartney) - Designation: B01. Known as Robin throughout Season 1; Grayson was, though only thirteen,[3] the most experienced member of the team.[4] He does not possess any superpowers, however, he is an excellent hand-to-hand combatant, tactician, and a technological genius. He has a flippant personality, and can be heard laughing in combat or when sneaking up on villains to unnerve and startle them. He repeatedly plays with the English language, particularly with words which cease to function without prefixes, such as "disaster" ("aster"), "overwhelmed" ("whelmed"), and "distraught" ("traught"). Batman had forbidden Robin from revealing his secret identity to the team[5], though Kid Flash was aware of it. Robin acts as team leader when Aqualad is unable to. Aqualad sees Robin as reluctant to lead the team, feeling that he doesn't know enough. "Eventually he shows that he is a natural born leader. And that's just part of what you'll see from Dick Grayson".[citation needed] In Season 2 (set five years later in the future), Dick has assumed the identity of Nightwing while Tim Drake has assumed the mantle of Robin. Nightwing has become leader of the team, assigning and participating in missions. Dick is revealed to apart of the top secret deep cover mission alongside Aqualad who acts as a mole to infiltrate the Light with only Wally and Artemis aware of the truth, but gradually begins to realize how his secrecy and reckless decisions endangered the lives of his friends and teammates who become further involved. After "Endgame", Dick decides to take a leave of absence after Wally's sacrifice and leaves Barbara in charge if they need any help. Between Seasons 2 and 3, he's become leader of his own team alongside Oracle; later recruiting Tigress, Superboy, and Black Lightning, but is also secretly a member of the Anti-Light to use the Light's methods against them alongside Batman and the Justice League and Team leaders. During the season, Dick still has trouble moving on following Wally's death, but later manages to finally come to terms and accept his loss and later rejoins the Team. In Season 4, Dick and the original Team re-open the investigation into Superboy's death and finally discovers he is still alive, is trapped inside the Phantom Zone as well as the conspiracy surrounding his disappearance and are now working to find a way rescue him. He later moves to intercept General Zod and his forces at the Fortress of Solitude, only to have an ice structure brought down his head, and stopping his heart, apparently killing him, but actually faked his demise by slowing his heartbeat and faking a cut. He reunites with the heroes and altogether, they defeat the Kryptonians in Metropolis and finally succeed in saving Superboy.
- Aquaman II / Aqualad / Kaldur'ahm[3] (voiced by Khary Payton) – Designation: B02; later 27. In Season 1, Kaldur'ahm (or "Kaldur" for short) was the sixteen-year-old leader of the team. His powers, channeled through the tattoos on his arms, are a mixture of Atlantean sorcery and science.[citation needed] He displays super strength, durability, as well as the ability to breathe and speak underwater, typical of Atlanteans. He also possesses the ability to form hard water constructs through the use of his Atlantean water bearers and to generate electricity.[6] He was selected as the initial leader for the Team, but stated that he did not want to remain leader and wished to turn over leadership to Robin when he was ready, saying that it was his destiny to lead this team.[7] In Season 2 (set five years later), Aqualad is Nightwing's mole in his father Black Manta's organization to infiltrate the Light and discover who their partner is. His "defection" is based upon his being the son of Black Manta (which Aquaman covered up) as well as the death of Tula. When Miss Martian fights Aqualad later, her psychic abilities caused her to learn about Aqualad and Tigress' true mission with the psychic attack leaving Aqualad in a catatonic state. To cure his son (thanks to Tigress' suggestion), Deathstroke and Tigress capture Miss Martian who manage to restore his mind. During the Summit, he and Tigress were revealed to be the spies and after their mission is complete, Aqualad returns to his post as leader once again. By Season 3, Kaldur has become Aquaman II and is co-leader of the Justice League along with Wonder Woman. Kaldur is secretly a member of the Anti-Light, consisting of Batman, Wonder Woman, Nightwing, Miss Martian, Oracle and Robin as they plan to use the Light's methods against them which they keep secret from the rest of the League and Team. However, by the end of the season, following the Anti-Light's exposure, both Kaldur and Wonder Woman willingly step down and appoint Black Lightning as the Justice League's newest leader. In Season 4, Kaldur has trouble coping with Conner's death and tries to distract himself by focusing on the current problems in Altantis from rising issues between the cities, stopping Ocean Master and locating Arion's lost crown. By the end of his arc, Kaldur decides to take a leave of absence from the Justice League and will now be sharing the mantle of Aquaman alongside his returning mentor Orin and fellow former protege Lagoon Boy. After returning from his sabbatical, Kaldur learns of Superboy's survival and works with the Team to save him from the Phantom Zone and defeat the House of Zod. In the aftermath, Kaldur and League decide to parole the captive Kryptonians on Trombus.
- Kid Flash I / Wally West[8] (voiced by Jason Spisak) – Designation: B03. During Season 1, Kid Flash is the team's fifteen-year-old speedster. He has enhanced speed,[5] although he has not fully mastered his abilities, often falling down while running at high speeds due to a misstep. Kid Flash cannot vibrate his molecules through solid objects like the Flash and gets a bloody nose if he attempts to.[5] He is a flirt, beginning with M'gann and extending to any woman he comes into contact with. Originally, Kid Flash has a rocky relationship with Artemis, constantly fighting and bickering, but slowly grows throughout the first season, eventually developing strong and mutual romantic feelings for each other, but are reluctant to confess how they feel. Kid Flash and Robin know each other outside the team, aware of the other's secret identities. Wally likes to collect souvenirs from the team's missions, such as T. O. Morrow's robotic eye and Cheshire's mask.[5][9] Ava Dordi, of the Palo Alto Voice notes that Jason Spisak "captures the Lighthearted essence of Kid Flash well".[10] In Season 2 (set five years in the future), Kid Flash has given up the superhero life and is in a relationship with Artemis with the two living and attending college together. Wally does however, assume the guise of Kid Flash once again during the crisis involving Neutron wherein he assists Impulse and the two Flashes (Jay Garrick and Barry Allen) with containing a major explosion. It is revealed that Wally was aware of Nightwing's plan to fake Artemis's death so she could be placed in deep cover alongside Aqualad. He returns to the team during "Summit" and helps to stop the Reach's final attack on Earth. During "Endgame", he, along with The Flash and Impulse manage to control the Magnetic Field Disruptor but due to his slower speed, the chrysalis energy siphons off onto him, causing him to disappear.
- Superboy / Kon-El / Conner Kent (voiced by Nolan North) – Designation: B04, later D09.[citation needed] Superboy is introduced as a sixteen-week-old clone of Superman (later revealed to be a hybrid clone of Superman and Lex Luthor) created by Project Cadmus. Although he does not have all of Superman's abilities, he has super strength, invulnerability, enhanced hearing,[11] and later infrared vision.[7] Lex Luthor later gave Superboy a set of patches which suppresses Superboy's human DNA, giving him his full Kryptonian abilities, similar to those of Superman's; however they only last for typically an hour, and his aggression increases as well. Superboy is typically sullen, ill-tempered, grumpy, and hates being told what to do. His nonexistent relationship with Superman only adds to this anger. He and Miss Martian also begin to develop strong and mutual romantic feelings for each other. They become couple when they go under cover in Belle Reve together and attempt to keep their romance a secret until everyone eventually finds out. Five years after the events of Season 1, Superboy has remained on with the Team and his formerly apprehensive relationship with Superman has greatly improved, with Superman now referring to him as a brother. Conner is more in control of his anger, resourceful and more familiar with alien technology. Superboy has also recently ended his and Miss Martian's relationship due to M'gann using her telepathic powers to violently extract information from enemies; even more so, she tried to tamper with his mind to try and make him forget that he was upset with her. Despite their break up, they still remain very much in love with each other and while they attempt to ignore and hide their feelings, they finally work on restoring their relationship by the end of the season. In Season 3, set two years later, Conner and M'gann have fully mended their relationship and they now live together in Happy Harbor. Conner proposes to M'gann in the premiere and they become engaged. Superboy joins Nightwing's team and works on training the new young heroes alongside Nightwing, Tigress and Black Lightning, but still retains his place on the Team while at the same time, Superboy is beginning to feel the pressure to step up in Superman's absence. By the end of the season, Superboy reveals himself as Superman's clone, becomes a public hero and joins the Outsiders. In Season 4, Superboy and Miss Martian travel to Mars in preparation for their long-awaited wedding, while unaware they secretly being followed by Saturn Girl, Phantom Girl and Chameleon Boy, who are protecting Superboy against Lor-Zod to save their future since Superboy's inspiration and heroism would form the Legion of Super-Heroes. Superboy later sacrifices himself to stop Ma'alefa'ak's bomb from killing the martian race and appeared to have died in the process due to the bomb having been laced with kryptonite, but unknown to everyone, he is revealed to be alive and was saved by Phantom Girl, who sent them both into the Phantom Zone in an effort to save Superboy, but was left comatose. Superboy attempts to remain strong, but begins to suffer from Zone-Sickness, causing hallucinations as well as amnesia, and later encounters General Zod, Lor-Zod’s father, who begins to take advantage and manipulate him. Superboy is later reunited with his friends who have come to rescue him, but due to lingering Zone-Sickness and believing he can't trust himself anymore, he remains under Zod’s control. Eventually, Superboy is finally freed from the Phantom Zone and his mind restored after being reunited with Miss Martian and works together alongside Superman and the original team to defeat the Zod's once and for all. By the end of the series, Superboy and Miss Martian finally get married in a private ceremony with all their closest friends and family, and he is subsequently shown to have rejoined the Outsiders in the Targets miniseries.
- Miss Martian / M'gann M'orzz / Megan Morse[12] (voiced by Danica McKellar) – Designation: B05. Miss Martian is Martian Manhunter's teenage niece,[13] as well as being an inexperienced superhero.[8] As a Martian, she has telekinesis, telepathy, and flight. Additionally, she can shape-shift to a limited extent. She has stated that she cannot become intangible as her uncle can, implying that this is an advanced skill; but by Season 2, she had learned this power.[5] In later episodes, Martian Manhunter discovers that her raw abilities, particularly in terms of telepathy and mind control, are potentially greater than his own. She pilots her own bio-ship, which transports the team and can become camouflaged with the surrounding area. She is kind and optimistic, but has a naive streak born of having learned about life on Earth through television shows. In line with this, she makes regular use of the catchphrase "Hello, Megan!" when suddenly realizing something. She becomes romantically involved with Superboy while working undercover with him in Belle Reve. While it is revealed to the viewer in the episode "Image" that she is concealing her identity as a non-humanoid White Martian, she finally reveals her true form to the team in the episode "Usual Suspects", though Superboy had known since they had mind-bonded in the past. Danica McKellar thinks her character is "Awesome. Like most of the characters on the show, she's dealing with two very different but coexisting aspects of her life: she's a superhero and also an insecure teenager, all at the same time."[14] In Season 2, five years later, she has become more confident in her abilities and lost her naive streak. Garfield Logan (the current Beast Boy) from the episode "Image" has become her adopted brother after the death of his mother. Miss Martian and Superboy are also revealed to have ended their relationship and following their break up, she has started dating Lagoon Boy. It's later revealed Superboy ended their romantic relationship because he disapproved how M'gann was abusing her powers to get information from her enemies, rendering the victim in a comatose state, to the point where she's "no better than Psimon", but the final straw was when she attempted to make him forget he was upset with her. However, she eventually comes to realize the error of her ways on how she has been abusing her powers and later breaks up with Lagoon Boy when she admits he was only her rebound boyfriend during "Intervention". By the end of the season, she begins to repair her relationship with Superboy. In Season 3, M'gann has become the leader of the Team and has adopted a new appearance that more closely resembles her White Martian heritage while her relationship with Superboy has been fully restored as they now live together and have recently gotten engaged. Miss Martian is later revealed to secretly be a member of the Anti-Light, consisting of other leaders to secretly use the Light's methods against them which are later exposed, causing a strain on her relationship with Superboy. By the end of the season, however, Miss Martian steps down as leader of the Team and reconciles with Superboy. In Season 4, Miss Martian and Superboy travel to Mars to have a traditional Martian wedding ceremony with Beast Boy and Martian Manhunter accompanying them, but get drawn into the planets escalating problems. Miss Martian is left heartbroken when Superboy is supposedly killed, having sacrificed himself to save the martian population from a deadly bomb left by her brother and Lor-Zod. Miss Martian confronts M'comm to avenge Superboy, but discovers he had nothing to do with the Kryptonite laced into the bomb and when the Justice League run out leads in the investigation, she falls deeper into mourning, but has begun to accept the help and support of her family and friends. Eventually, she finally comes to learn of Superboy's survival after meeting his savior, Phantom Girl and sets out with the other heroes to free him from the Phantom Zone and the Zods control over him. By the end of the series, Miss Martian and Superboy are reunited and finally get married.
- Tigress / Artemis / Artemis Crock[15] (voiced by Stephanie Lemelin) – Designation: B07. Artemis was the team's fifteen-year-old archer.[8][16] Like Robin, she has no superpowers, but is very skilled with a bow and arrow. She is introduced as Green Arrow's "niece" but it is later revealed that this is not the case. Red Arrow, who knows she isn't, believes that there was good reason behind Batman and Green Arrow's decision to add her to the team, as well as their concealment of her real identity, and therefore agrees not reveal his suspicions about her to the rest of the group—but warns Artemis to not harm his friends. She is the daughter of the villain Sportsmaster and the now paraplegic ex-villain Huntress, as well as the sister of Cheshire.[17][18] In Season 2 (set five years in the future), she and Wally West (Kid Flash) left the superhero life, and are in a relationship, with the two living and attending college together, also owning a dog named Brucely (based on a real dog Stephanie Lemelin owned, and later shown to have the designation C03) which Wally got for her. She returns to duty, only to subsequently fake her death so she can go undercover with Aqualad within Black Manta's organization, adopting the identity Tigress, and apparently help him complete his long-term mission. Nightwing supplies her with a charmed necklace crafted by Zatanna to conceal her true appearance. As part of her cover, she fakes a discreet love affair with Aqualad when questioned. After Wally's sacrifice during "Endgame", she returns to the team using her Tigress identity with her blonde hair. During the time skip between season 2 and 3, Artemis retired again, her and Brucely moving in with her sister's family before helping Nightwing with the Outsiders. Artemis continues to silently mourn Wally's loss, but after seeking help from Zatanna, she later manages to finally come to terms and accept he is gone, allowing herself to move on with her life. Tigress later becomes the Team's newest leader. In Season 4, Artemis is revealed to have become a college professor teaching literature, as well as in a relationship with Jason Bard, and is finally truly enjoying and moving on with her life. However, she falls into mourning after learning about Conner's death which motivates her to reach out to Cheshire until she finds herself dealing with members of the League of Shadows, both claiming to have defected. Artemis seeks Jade's help in learning which among them is telling the truth and further assistance in rescuing her teammate, Orphan who was kidnapped by the Shadows in exchange for Cassandra and Onyx. In the end, Artemis and Jade begin to truly reconcile and Artemis accepts Cheshire's decision to stay on Infinity Island with Ra's al Ghul's faction to reform herself. By the end of the season, Artemis learns of Superboy's survival, works alongside members of the original Team to save him from the Phantom Zone, defeats the Zods and happily serves as a bridesmaid at Miss Martian and Superboy's wedding.
Expanded members
The following members were added to the team after the series premiere at different times:
- Doctor Fate / Zatanna / Zatanna Zatara (voiced by Lacey Chabert) – The daughter of Justice League member, Zatara. She first appears in "Humanity" and sporadically through the later episodes. Zatanna is often annoyed by her father's overprotectiveness, but is devastated when he sacrifices himself to become the new Doctor Fate. In the aftermath, she permanently moves into Mount Justice and becomes an official member of the team in the episode "Misplaced". Her powers, like her father's, are magical, and like her father's, her spells are spoken in reverse order. In Season 1, Zatanna and Robin develop feelings for each other and their romance grows as Robin comforts Zatanna after her father's sacrifice. By the end of season 1, she kisses Robin and they officially begin a romantic relationship. However, the relationship does not last, breaking up sometime in the five years, but Zatanna and Robin, later Nightwing, still remain on good terms. By the beginning of Season 2, Zatanna joins the Justice League alongside Rocket. In the ongoing years, she grows as one of the most powerful sorcerers in the world and even takes on several protégés over time. In Season 4, Zatanna and her protégés face off against Child, a new and far deadlier Lord of Chaos who has come to wreak havoc on the world. With the help of both Doctor Fate and Klarion, they succeed in defeating Child and in the process, Zatanna and Nabu reach a new agreement. Zatanna volunteers herself and two of her protégés to become rotating hosts for Doctor Fate, freeing Zatara and reuniting father and daughter at long last which was secretly her hidden agenda all along. Zatanna also sees a vision of Superboy trapped in another dimension, but remains unaware that he is still alive, believing she had seen his spirit. It is only after she reaches out and gathers various magicians and in her role as Doctor Fate, casts a searching spell that she confirms Conner's survival. By the end of the season, Zatanna and the original Team work together to rescue Superboy from the Phantom Zone and afterwards, Zatanna serves as one of Miss Martian's bridesmaids at her and Superboy's wedding. Designation: B08, later 25.
- Red Arrow / Speedy II / Will Harper / Roy Harper (voiced by Crispin Freeman) – Red Arrow is the team's male archer. Like Robin and Artemis, he has no superpowers, but is very skilled with a bow and arrow. He is also the adopted son of Green Arrow. Originally Speedy, he left Green Arrow's side in "Independence Day", as a result of feeling patronized by the League, who continued to treat him and the others as sidekicks dependent on their mentors, and adopted the alias Red Arrow. He refused to join the group in "Welcome to Happy Harbor". However, he still assisted the team such as in "Targets" and is convinced by Green Arrow to join the team in "Insecurity". In the episode "Usual Suspects", he becomes the first member of the Team to join the Justice League as a full member. However, in "Auld Acquaintance", Harper is told by Vandal Savage that he is a Cadmus clone much like Superboy and was the "mole" implanted by the Light, while the original Roy Harper is in custody of the enemy. In Season 2, Roy is shown on the edge of a breakdown, still searching for his original counterpart. In the episode "Salvage", it is revealed that Roy married Cheshire and unknowingly fathered a daughter with her. Cheshire is willing to help him find his original counterpart so as to help Roy find some peace. Shortly after Roy and Cheshire flew to Tibet to find the original Roy they recover and bring him back to America, where the real Roy Harper recovers in the Star City hospital with the clone and Green Arrow watching over him. He later teams up with Cheshire to deactivate one of the Reach bombs in "Endgame" and later retires to be with his daughter. In Season 3, Roy has changed his name to Will and has started his own private security company, Bowhunter Security. He resides in Star City and lives with Artemis, who helps him to take care of his daughter, Lian. In season 4, he is shown to be a possible reserve member of the Justice League and later serves as one of Superboy's groomsmen at the wedding. In the Targets comic, it was revealed Red Arrow had previously failed to save King Josef, Perdita's father, during his time still under the control of Sportsmaster, and promised not to lose her either, which is hampered by an army of drones loyal to Count Vertigo capturing her. Designation: B06, later 21.
- Rocket / Raquel Ervin (voiced by Kittie in season 1 and season 2, Denise Boutte in "Intervention" and season 3) – Straightforward and bold, if inexperienced, Rocket is the apprentice of the superhero Icon. She uses a piece of alien technology called an inertia belt, allowing her to store and manipulate kinetic energy. She generally uses this to fly and grant herself some super-strength and a personal force field. She joins the team in the episode "Usual Suspects", the same episode her mentor joins the Justice League. In the five years between Seasons 1 and 2, she has joined the Justice League and is engaged. As of Season 3, she has had a son, Amistad. In season 4, she struggles with Amistad's autism as she goes with Forager and Jay Garrick to New Genesis for a conference with the New Gods and the Green Lantern Corps, but develops an untrusting relationship with Orion after learning he is the son of Darkseid, but eventually comes to accept and make peace with him as well as Amistad's autism after finally coming to terms and understanding their struggles. During this time, Rocket comes to learn about the existence of the Phantom Zone and encounters Lor-Zod who steals the Phantom Zone Projector to free his imprisoned parents, but remains unaware of his role in Superboy's apparent death and later witnesses a brief glimpse of the Zone before the Projector is destroyed. Towards the end of the season, Rocket comes to learn Superboy is still alive and realizes he is trapped inside the Phantom Zone and sets out with the rest of the original Team to save him and bring him back. She is briefly thought to have perished when trapped inside a collapsing Boom Tube, but is saved and brought to Metron's vault and later goes to Metropolis to help her friends. She attends Miss Martian and Superboy's wedding as a bridesmaid and agrees to parole the captive Kryptonians on Trombus. Designation: B09, later 26.
- Aquagirl / Tula (voiced by Cree Summer) - A student at Atlantis's Conservatory of Sorcery and Kaldur's former love interest. When Kaldur began spending more time on the surface world, Tula entered into a relationship with Garth. She joined the Team during the five years in between Seasons 1 and 2, but died on a mission which left Aqualad devastated. This event was used as a ruse for him to serve as the Team's mole to uncover the secrets of The Light's unidentified partner (who turned out to be Black Beetle of the Reach). Designation: B11.
- Oracle / Batgirl / Barbara Gordon (voiced by Alyson Stoner) – Originally a classmate of Dick's at the Gotham Academy. In the time between Seasons 1 and 2, she assumed the identity of Batgirl and became a member of the Team. Between Seasons 2 and 3, she's become paralyzed, has taken on the Oracle identity and has begun a romantic relationship with Nightwing. She is a member of the Anti-Light, serving as technical support to the various team of superheroes, including Nightwing's team. Her paralysis is revealed to have caused by Orphan when she was sent to kill Joker, and she jumped in the way to take the blow from her. Designation: B16.
- Bumblebee / Karen Beecher (voiced by Masasa Moyo) – A young scientist and girlfriend of Mal Duncan. She and Mal were classmates of Superboy and Miss Martian at Happy Harbor High School. Her suit acts as armor and imbues her with bee-themed powers including shrinking, and flight. Karen often works with Professor Palmer a.k.a. the Atom; at one point, they attempted to remove the scarab from Jaime, but its defenses nearly killed them. As of Season 3, she has left the Team and became pregnant. Later in the season, she gives birth to a daughter, repairs a hole in her heart, and activates her meta-gene to give her a better life. She is shown in season 4 to be a possible reserve member of the Justice League and serves as a bridesmaid at Miss Martian and Superboy's wedding. Designation: B17, later E06.
- Guardian III / Mal Duncan (voiced by Kevin Michael Richardson) – The boyfriend of Karen Beecher and classmate of Superboy and Miss Martian at Happy Harbor High School.

During an encounter with Despero in "Cornered," he assumed the Guardian superhero armor which had previously belonged to Jim Harper. By the time of "War", he operates as a full member of the team as the Guardian. As of season 3, he has retired from the Team so he can be with Karen and his daughter. Despite this, he is shown in season 4 to be a possible reserve member of the Justice League. Designation: B24.[19]
- Aquaman III / Lagoon Boy / La'gaan (voiced by Yuri Lowenthal) – A student at Atlantis' Conservatory of Sorcery. Sometime during the five-year lapse between Seasons 1 and 2, he joined the Team. He and Miss Martian also became romantically involved until Miss Martian ended the relationship in "Intervention" when she realized he was only her rebound boyfriend and that she still loved Superboy. He was temporarily a prisoner of The Reach, captured by Aqualad as a way to spare his life. Lagoon Boy was later rescued during the raid on the Reach's ship. Between Seasons 2 and 3, Lagoon Boy has left the Team and returned to Atlantis. In Season 4, Lagoon Boy has greatly changed and matured and is revealed to be in a happy polyamorous marriage while excitingly awaiting the birth of his child alongside his wife and husband. Lagoon Boy also expresses shame and remorse over his past grudge against Superboy and feels guilty he never made amends. Lagoon Boy is selected to join the Justice League and will now share the mantle of Aquaman alongside Kaldur and Orin. Designation: B18, later 45.
- Arsenal / Speedy I / Roy Harper (voiced by Crispin Freeman) – The original Roy Harper. Eight years before Season 2, it was revealed that Lex Luthor captured Speedy and amputated part of his right arm to create a clone that would serve as The Light's mole. Having fulfilled his purpose as a mole, The Light no longer had a use for him, prompting the clone to join The Team and find the original Roy. However, during the five-year transition between Seasons 1 and 2, everyone except his clone counterpart assumed The Light killed off Harper. The original Roy was found in Tibet by his clone counterpart and Cheshire. After recovery in "Satisfaction", Roy learns the whole truth behind the events of the first two Seasons and recalls of dealing with Luthor in his last mission, prompting him to take vengeance. Although Roy almost succeeds, Lex anticipated this and outnumbers him. In exchange for his life, Lex gives Roy a mechanical arm filled with high-tech weapons. Roy accepts Luthor's offer minutes later upon Green Arrow and Red Arrow's arrival and adopts the persona Arsenal. After his paranoia caused the Team to be captured by the Reach, Arsenal is booted from the Team until he can get his paranoia under control. This causes him to take up the offer to ally with the meta-humans Luthor had previously employed. After Arsenal gets the truth out of Lex Luthor during his web chat with the group about Deathstroke's secret mission, Arsenal and those with him cut off all ties with Lex Luthor and go on their own path. In Outsiders, Arsenal helps his "brothers" Will and Jim with a mission for Will's company Bowhunter Security. In the canonical audio episode "The Prize," Arsenal accepts an offer to return to the team from its newest leader, Tigress.[20] He later shows up to help Artemis when Onyx is stalking her. Designation: B25.

A device called the Scarab is permanently attached to his spine, providing him a battle suit and advises him on what it feels is the best course of action in many situations. However, Jaime frequently ignores this advice as it is often aimed at violent solutions to problems and is seen at these times to be talking to himself. Superboy is currently the only person that knows that Jaime is talking to the scarab; Jaime compares it to Jiminy Cricket. The scarab is believed to be the last invention made by Ted Kord before the Light killed him, but it is revealed in the episode "Before the Dawn" that its origins lie with the alien organization known as the Reach, who seek to retrieve the scarab, which will kill Jaime. In the future, a Blue Beetle under control of the Reach is shown to have enslaved the human race which Impulse traveled back in time to prevent from happening. Though the Reach do get control of Jaime's body thanks to the Green Beetle, he, the scarab, and Green Beetle are freed from the Reach thanks to an intervention from the rest of the Team and magic from Zatanna.

In the aftermath, he finally fulfills his duty and serves as Superboy's best man at his and Miss Martian's long awaited wedding. This version of Superman doesn't have his super or freezing breath and has to use an oxygen mask to breathe in airless environments, due to the fact that the show's creators believe Kryptonians having these abilities wasn't believable. Designation: 01.
- Wonder Woman / Princess Diana / Diana Prince (voiced by Maggie Q) – Member and co-founder of the Justice League, and Princess of the Amazons. When Vandal Savage infected the Justice League with The Light's Starro-Tech, Wonder Woman is one of the six Justice League members to be missing for 16 hours. Designation: 03.
- Doctor Fate / Zatara / Giovanni Zatara (voiced by Nolan North) – Member of the Justice League and father of Zatanna. He was the second substitute den mother while Red Tornado was missing. Due to Nabu (voiced by Kevin Michael Richardson) stating that the world would always need Doctor Fate, Zatara offers himself to become the new Doctor Fate in lieu of his daughter. His Doctor Fate persona was officially inducted into the Justice League on December 30, 2010, with Zatara remaining host through season 2. In Season Three, it is revealed that Zatara struck a deal with Nabu years before the season's events. Once every year, the latter releases the former so he can be with Zatanna for one hour before promptly putting the helmet back on until the next year. A new deal with Nabu in which Zatara rotates the mantle with Zatanna, Thirteen, and Khalid Nassour finally frees him up to be free longer and also enables Zatara to be considered a possible reserve member of the Justice League. He is briefly shown to be Doctor Fate again before he hands the helmet to Zatanna during her investigation into Superboy's whereabouts. Designation: 11 (as Zatara) and 17 (as Doctor Fate).

Antagonists
The Light
The Light are the characters in Season 1 who directed the course of events throughout the series. The group was conceived by Vandal Savage who views himself as a first among equals.[30] The leaders act as a board of directors, their identities known only to a select few individuals that work with them.[31] The end goal is improve humanity and set it as a dominant race in the universe: they view the superheroes as interfering with the natural order of things and that Earth must employ survival of the fittest if it intends to exist and thrive in an ever-changing universe.
Among its members are:
- Vandal Savage / Vandar Adg / Varl'jat / Marduk / Genghis Khan (voiced by Miguel Ferrer in the first two seasons; David Kaye in later seasons following Ferrer's passing) – The immortal founder and leader of The Light. Over the course of 15,000 years, Savage had gone by many names and conquered many lands for the sake of power. He convinced Klarion the Witch Boy to channel the latter's chaos power for the former's vision, and formed a partnership with Darkseid and Apokolips to conquer the entire galaxy before the two worlds battle each other for complete supremacy. His 'survival of the fittest' views are why he views the Justice League and other subsequent heroes as a constant obstacle for him and his colleagues. Despite this, he is willing to work with the heroes to defeat a third party (Light-partner or otherwise) if they potentially hinder his long-term plans. He was temporarily given the designation A04 near the end of the first season when the Justice League were mind controlled.
- Cassandra Savage (voiced by Zehra Fazal) - One of Vandal Savage's daughters and current heir, a member of the League of Shadows. In season 4, the left side of her face is scarred with her left eye blind, and her left arm is amputated (though the origins to this is varied). She seeks to defect to the heroes in response to Olympia's death, but Onyx disputes this and suggests she is trying to feign defection as Terra formerly had in the past. It is revealed she lied about her defection as a ruse to get stolen data to the League of Shadows, and she used a glamour charm to fake her new appearance.
- Olympia Savage (voiced by Jenifer Lewis) - One of Vandal Savage's daughters. When she started to become senile, Vandal was forced to mercy kill her by breaking her neck.
- Ra's al Ghul (voiced by Oded Fehr) – Member of The Light and leader of the League of Shadows who is an enemy of Batman. In Season 3, the Team and the Outsiders encounter Ra's al Ghul on Infinity Island, who tells them he is no longer part of the Light or leading the League of Shadows. Though he secretly remains in contact with Vandal Savage.
- Talia al Ghul (voiced by Zehra Fazal) - Ra's al Ghul's daughter and his second-in-command who has a love-hate relationship with Batman. In Season 3, it's revealed she has a son called Damian Wayne. Fazal reprise her role as Talia al Ghul from the film Batman: A Death in the Family. In the tie-in comics, Talia was responsible for turning Matt Hagen into Clayface.
- Sensei (voiced by Keone Young) – A high-ranking member of the League of Shadows. This version is not Ra's al Ghul's dad.[32]
- Ubu (voiced by Fred Tatasciore) - A super-strong man and member of the League of Shadows who is loyal to Ra's al Ghul.
- Lex Luthor (voiced by Mark Rolston) – Member of The Light, CEO of LexCorp, and archenemy of Superman. He played a part in the creation of Superboy by donating his DNA (to stabilize the uncontrollable Kryptonian half). Lex Luthor was also responsible for the real Roy Harper missing half of his right arm to further the cloning projects. At the end of the second season, he is named Secretary General of the United Nations after helping the Team and the Justice League stop the Reach's plot. In Season 3, Lex Luthor put up restrictions that prevent the Justice League from interfering in the Light's metahuman trafficking rings. While he later creates Infinity, Inc. as his own team of heroes, ultimately, Black Lightning, Cyborg, Superman, and Superboy out him using evidence from Terra's earpiece, forcing him to resign in favor of Troia and negating his restrictions. Despite this, he remained a member of the Light in season 4, and Superboy in the Phantom Zone hallucinates himself doing Lex's bidding until he meets General Zod. The Targets miniseries reveals that Lex Luthor is the true builder of an army of drones loyal to Count Vertigo. He also used the kryptonite found by Perdita to convert Juan Cordero into Metallo. After Perdita is rescued, Kaldur, Zatanna, Rocket, Cyborg, and La'gaan confront Lex and tell him that Perdita is family, and therefore off-limits to further schemes by the Light.
- Mercy Graves - Lex Luthor's cybernetic and silent bodyguard that wears a business suit.
- Queen Bee (voiced by Marina Sirtis) – Member of the Light and dictator of Bialya. In this show, Queen Bee possesses the ability of persuasion over most men and some women, with the Targets miniseries revealing even non-binary beings such as Halo can be enthralled. She is the first to discover Miss Martian's true form and uses this to blackmail her through the first season. It was her military's attack that led to Beast Boy's origin leading Queen Bee to later murder his mother, who Miss Martian idolized, in retaliation. The Targets miniseries reveals that after she enthralls Red Arrow, Arsenal, and Halo, making them attack Miss Martian, Tigress, and Arrowette to the point of seemingly killing them, it's revealed that she cannot control anyone who has eaten garlic, with the three controlled heroes having consumed pills to fake their control and the other three using fake blood.
- Onslaught - A team of Meta-Human Enforcers working for Queen Bee. According to Holocaust, they "paid top dollar".
- Psimon (voiced by Alan Tudyk) - The right-hand man of Queen Bee who has telepathic powers. He often enjoys making the pun "Psimon says", based on the children's game, right before forcing someone to do his bidding. His function for The Light includes extending the range of Queen Bee's influence and being the most useful combatant against telepaths. To that end, he often faces Miss Martian in telepathic battle, usually to his detriment. In Season 3, he and Devastation are a couple.
- Devastation (voiced by Diane Delano) - A heavyset super-strong Caucasian woman who is an adversary of Wonder Woman. During the failed breakout attempt at Belle Reve, she was frozen by Killer Frost (who was trying to hit Superboy). In 2016, Devastation was seen working for Queen Bee in Bialya, preparing abducted runaways to be sent to the Reach. In Season 3, she and Psimon are a couple.
- Mammoth / Baran Flinders - Baran Flinders and his fraternal twin sister, Selinda, were members of The Cult of Kobra. After being injected with a hybrid strain of the Venom drug and the Blockbuster formula by his sister, he developed super strength and became very deformed. After Kobra's defeat, Mammoth was sent to Belle Reve where he took part in a failed breakout attempt. In 2016, Baran was working for Queen Bee in Bialya preparing abducted runaways to be sent to the Reach.
- Shimmer / Selinda Flinders - Selinda Flinders is a martial-artist who was Kobra's right-hand woman. She is also the fraternal twin sister of Baran. After Kobra's defeat, Shimmer was sent to Belle Reve where she took part in a failed breakout attempt. In 2016, Shimmer was working for Queen Bee in Bialya preparing abducted runaways to be sent to the Reach. However, Miss Martian took her out with a brain blast. Later, she was experimented on by the Reach, which activated her metahuman powers of transmutation.
- Icicle Jr. / Cameron Mahkent (voiced by Yuri Lowenthal) - A criminal with cryokinetic powers and the son of Icicle Sr. He attacked a bridge in Star City only to be defeated by Green Arrow and Speedy. He was sent to Belle Reve where he participated in his father's failed breakout plan. During that time he developed romantic feelings for Miss Martian and befriended Superboy when they were disguised as Tuppence and Tommy Terror respectively. When he learns their true identities he has held a grudge against them ever since. In 2016, Icicle Jr. was working for Queen Bee in Bialya preparing abducted runaways to be sent to the Reach. He was also chosen by the Light for a strike team led by Kaldur to capture Blue Beetle. In 2018, he is seen as part of a group of villains collectively called "Onslaught" who work security at a metahuman auction. He encounters and battles against Superboy, showing they've developed a frenemy relationship to the point where he congratulated him upon learning of his engagement to Miss Martian mid-battle. This is also further shown as he attends their wedding at the end of season 4 and catches the bouquet of flowers.
- Terror Twins / Tommy and Tuppence Terror (voiced by Yuri Lowenthal and Danica McKellar respectively) - The Terror Twins are rash and arrogant fraternal twins who possess super-strength and invulnerability. Their arrest was vital in a plan to infiltrate Belle Reve as Superboy and Miss Martian would go undercover as the twins. In 2016, they were chosen by the Light for a strike team led by Kaldur to capture Blue Beetle and some of the other members of "The Team."
- Holocaust (voiced by Zeno Robinson) - A pyrokinetic metahuman who was part of an underground metahuman fight club secretly sponsored by Queen Bee.
- Match (voiced by Nolan North) - He is a genomorph created by Project Cadmus and the first attempt at cloning Superman which didn't go well since Kryptonian DNA is tricky to clone compared to that of earth's lifeforms. His name was derived from Luthor's desire to "have Superman meet his match." Match was freed by Superboy per his "father" Luthor's wishes. However, Match attacked Superboy after seeing his Superman-insignia. He had been programmed to respond to this, to attack Superman. Match then burned a backwards "S" onto his chest with heat-vision, mirroring Bizarro. By using the shields given to him by Luthor, Superboy was able to defeat Match. The pod containing Match was later stolen from Project Cadmus during the Light's raid. In the companion comics, Match is shown to have deformed, perhaps due to his incomplete genetic sequence. In the Targets miniseries, he is shown to have been recruited by Onslaught, battling the Outsiders alongside Mammoth, Shimmer, and Devastation in Greater Bialya. He is not able to contribute as long to the battle due to Metallo's kryptonite affecting him, but when the Outsiders do defeat the Onslaught members, Match is taken to the Fortress of Solitude to heal.
- Onslaught - A team of Meta-Human Enforcers working for Queen Bee. According to Holocaust, they "paid top dollar".
- Ocean Master / Prince Orm (voiced by Roger Craig Smith) – Board member of the Light and Aquaman's half-brother. Sometime after the events of Season 1, he was disgraced upon his identity being exposed to the authorities, incarcerated in Atlantis, and replaced with Black Manta on the Light. He returns in Season 3 operating on his own to kill the Justice League's families only to be killed himself by Lady Shiva to keep him from interfering in the Light's plans. However, the Light's Thrinos operation allowed them to make a clone of Ocean Master and insert the original's mind into a clone body of Arion that would be able to wear Arion's crown. The clone of Ocean Master is eventually cleared of mental programming by Miss Martian and allowed to go free by Aquaman.
- Brain (voiced by Nolan North in his first unofficial appearance, Corey Burton in the first official appearance) – Member of the Light. He was originally a man whose brain was put in a special mobile container. Brain and Klarion the Witch Boy worked with Professor Ivo to weaponize a fragment of Starro to create Starro-Tech. At the end of Season 2, he was captured by the Team and replaced by Ultra-Humanite as of Season 3.
- Monsieur Mallah (vocal effects provided by Dee Bradley Baker) – Brain's gorilla sidekick. In season 3, he appears as a member of the Suicide Squad.
- Klarion the Witch Boy (voiced by Thom Adcox-Hernandez) – Member of the Light and an associate of the Lords of Chaos. He and Brain worked with Professor Ivo to weaponize a fragment of Starro to create Starro-Tech. According to Greg Weisman, Klarion joined the Light mostly because it seemed like fun.[33] His partnership with Vandal lasted millennia, them having met in Atlantis 15,000 years ago and becoming locked in battle for 300 days, until they grew interest in one another. Having sunk Atlantis a long time ago per Vandal's deal with him, he is threatened when Child comes to Earth, seeking to replace him as the main Lord of Chaos. After Teekl was killed in the ensuing fight, he loses his earthly tether, forcing him to possess a school bus that Superman and Superboy saved during the events of season 1. His subsequent travels through time and space revealed him to be behind a running gag in which the bus popped up at peculiar times with the same driver and passengers trapped inside, repeatedly needing saving. He eventually finds Doctor Fate and Zatanna and gets them to help him defeat Child, finding a new cat to anchor himself to. Zatanna seeks him out due to his earlier bus shenanigans for knowledge on how to access the Phantom Zone, but he refuses to help, attacks her and the other heroes, and leaves. Vandal Savage and Ultra-Humanite later have Klarion retrieve most of the Phantom Zone inmates that got sent back to the Phantom Zone and have them imprisoned on Warworld.
- Teekl (vocal effects provided by Dee Bradley Baker) - Klarion the Witch Boy's familiar spirit, who took the form of a cat. If Teekl is destroyed, Klarion will have nothing to anchor him to the mortal realm. Klarion can occasionally power it up into a stronger form, but unlike most depictions of the character, which take the form of a werecat, Teekl's powered up form resembles a ruthless and fearsome Smilodon. Its destruction indeed happens during their fight against the Child, where her familiar Flaw kills Teekl by snapping its neck. However, Klarion is able to regain his presence by possessing another cat, who bears the same markings and name of its predecessor.
- Black Manta (voiced by Khary Payton) – Aquaman's nemesis and an associate of the Light and Aqualad's father. In Season 2, Black Manta replaced Ocean Master on the Light and was later captured by the Team. He later joined the Suicide Squad in Season 3 only to be returned to Belle Reve by the Outsiders.
- Slade Wilson / Deathstroke (voiced by Wentworth Miller in the first appearance, Fred Tatasciore in later appearances) - An assassin who was hired by The Light to replace Sportsmaster when he goes rogue in his quest to get revenge on Black Manta and his son for "killing" Artemis. Deathstroke helped Tigress capture Miss Martian so that Black Manta can have her restore Aqualad back to normal. In a flashback, it was revealed that he and Sportsmaster were responsible for the death of Ted Kord. In Season 3, he has joined the Light's council with Lady Shiva replacing him as enforcer and took Ra's al Ghul's place as leader of the League of Shadows.
- Count Vertigo (voiced by Steve Blum) – Member of the royal family of Vlatava, enemy of Green Arrow, and leader of the Injustice League. He is obsessed with seizing power from his niece, Queen Perdita. Unlike the others, he was not arrested due to his diplomatic immunity, which was revoked later that season by his niece when he was accidentally tricked into revealing his pact with Vandal Savage to ensure the failure of her heart transplant. In season 3, Count Vertigo takes advantage of the metahuman trafficking when he collaborates with Baron Bedlam. He later joins Bedlam in his coup of Markovia when they escape prison. The Targets comic shows him once again escaping prison with the help of an army of drones, which later proceed to capture Perdita. After arriving in Bialya to attempt to stop the rescue of Perdita, he reveals he intends to stage her assassination to set up a comeback story to trick the Vlatavan government into letting him back into power. His portrayal as a Vlatavan count is taken from DC Showcase: Green Arrow, with Steve Blum reprising the role from the short.
- Joe Henchy (voiced by Steve Blum) - Count Vertigo's brutish henchman who aids him in all his crimes. He was originally created for DC Showcase: Green Arrow.
- Sportsmaster / Lawrence Crock (voiced by Nick Chinlund) – A sports-themed agent of the Light. He is the ex-husband of Paula Crock, the father of Artemis and Cheshire, and grandfather to Lian Nguyen Harper. In a flashback, it's revealed that Sportsmaster and Deathstroke were responsible for the death of Ted Kord. When Artemis faked her death, he demanded an "eye for an eye" situation by being allowed to kill Aqualad. After discovering Artemis' survival, he helps her by allowing M'Gann to escape. Sportsmaster looks younger than his actual age which as of 2018 is 62, thanks to being in peak condition.
- Ultra-Humanite (vocal effects provided by Dee Bradley Baker in Season 1, voiced by Greg Weisman in Outsiders) – An albino gorilla supervillain with super-human strength and intellect and enemy of Superman. A former member of the Injustice League, Ultra-Humanite replaced Brain on the Light's council in season 3 where he now speaks through a vocalizer on his harness. In the tie-in comics, Ultra-Humanite was an old lady who transferred her brain into the body of an albino gorilla.
- Dr. Helga Jace (voiced by Grey Griffin) - The personal physician to Markovia's royal family as well as an agent of Bedlam. After Prince Brion was banished, the Outsiders allowed her to come with them to America so she can watch over the young prince as well as Halo. She has also entered a relationship with Black Lightning so she could secretly keep tabs on her young charges. As of the second half of season 3, she has begun making contact with a mysterious individual (later revealed to be the Ultra-Humanite) so she could study Halo further, as she sees her and the Markovs as her "children". In fact, she had a hand in killing Gabrielle Daou and was the one who gave Tara her powers. Designation: G04
- Lady Shiva / Sandra Wu-San (voiced by Gwendoline Yeo) - The League of Shadows' teacher and the Light's new enforcer. She confronted Ocean Master while he was planning to kill the Justice League's families. In response, she killed him by beheading him to prevent him from interfering in the Light's plans. She later fights Katana during Batman's mission to Santa Prisca, showing a desire to claim the Soultaker sword. She is later shown to be Orphan's mother, and captures her as a way to force Artemis to bring Cassandra Savage to Santa Prisca. In reality, because Cassandra Savage was a mole and not really defecting, Shiva just wanted her daughter, and some stolen intel Cassandra Savage was going to provide, all along, but when she threatens to kill Barbara Gordon, Orphan manages to beat her in combat, but refuses to kill her, enraging the experienced assassin.
- Zviad Baazovi (voiced by Yuri Lowenthal) - The ambassador of Markovia at the United Nations; replaced Granny Goodness on the Light's council. He is based on the DC Comics character Bad Samaritan, and has gained a mild psychic ability used to bring out the worst impulses in people. Zviad uses this to turn Geo-Force against the Team and get him to usurp Gregor as the King of Markovia and to motivate metahumans to willingly undergo activation via the tar.
New Gods of Apokolips
- Darkseid (voiced by Michael-Leon Wooley) - The ruler of Apokolips, the Justice League's greatest enemy, and Vandal Savage's master who encountered Vandal during his early days.

Her Goode Goggles, a type of VR technology, is used to test for and traffic metahumans until Beast Boy's use of it called attention to them. She deduces Halo to be the cause of the Anti-Life Equation, which takes away free will, and has her captured, upstaging Vandal Savage and forcing him to sell Granny out to the Team. She is defeated at the end of Outsiders thanks to Halo and Cyborg and is seen being tortured as punishment for her failure, while Zviad Baazovi replaces her on the Light. Despite this, she regains her former position after serving her punishment, and is later heard manipulating Mary Bromfield which led to her somehow ending up in the Female Furies.

He had tried to conquer the galaxy in the Legion of-Super Heroes' time shortly after he was paroled from the Phantom Zone, but after he was re-imprisoned, Lor seeks to free him in the present. Manipulating Superboy into siding with him, he opposes the Team's efforts to bring him back with them, then escapes through the Boom Tube on Trombus alongside Ursa, Faora, and Superboy, meeting Lor on the other side. After claiming the Fortress of Solitude on Earth, he attempts to announce the conquest of the planet in Metropolis, giving Superboy the choice to kill Superman. Instead Superboy refuses and is turned back to the side of the heroes, leading to General Zod being banished back to the Phantom Zone by the combined power of Superman and Superboy.

The primary antagonist of season 4, he was born in the Legion of Super-Heroes' future, and sought revenge against them for re-imprisoning his parents to the Phantom Zone. He targeted their inspiration, Superboy, so the Legion would never be formed and therefore with no one to battle his father, General Zod would rule the galaxy. Following his apparent success at assassinating Superboy, Lor-Zod decided to free his parents and followers early in the past and began his search for the Phantom Zone projector, discovering it was in Metron's vault.

He joins his parents' goals to conquer Earth, but is foiled by the Team and forced to flee in the now repaired Time Sphere after his father and the other inmates, except Ursa, are banished back to the Phantom Zone. However, Lor is unable to control the Time-Sphere, unaware Metron pre-set the controls to get Rocket to Earth with full knowledge Lor would take the Time Sphere, and also pre-set the coordinates so Lor would wind up back on Mars when Superboy was destroying the gene bomb. The Time Sphere abandons Lor to be caught in the explosion from the bomb, which disintegrates him and reveals him to be the true owner of an ash silhouette that the other heroes mistook as belonging to Superboy. As his mother Ursa is still pregnant, she will likely give birth to a new Lor-Zod eventually.
