Contents 1 Main characters 1.1 `` The Team '' 1.1. 1 Founding members 1.1. 2 Expanded members 2 Recurring characters 2.1 Justice League 2.2 Antagonists 2.2. 1 `` The Light '' 2.2. 2 Villains and rogues 3 Guest characters 4 References Main characters `` The Team '' The original 6 members of `` The Team ''. From left to right : Artemis, Robin, Kid Flash, Superboy, Miss Martian, and Aqualad. Founding members The initial six main characters were chosen by the producers, from a list of potential candidates of 50 to 60 DC Comics teenaged superheroes. The criteria consisted of age, powers, personality, cultural icon status, and dynamics. An additional regular, Zatanna, was introduced partway through the first season, and Rocket was added at the end of the first season. Aqualad / Kaldur'ahm ( voiced by Khary Payton ) -- he is aqualad 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. 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. 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. In Season 2 ( set five years in the future ), Aqualad is Nightwing 's mole in his father Black Manta 's organization in order 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 in an earlier Team mission. 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 an apparently - catatonic state. His body was carried away by Tigress. But soon in order to cure his son ( thanks to Tigress ' suggestion ), Deathstroke and Tigress capture Miss Martian and manage to restore him. During the summit, he and Tigress were revealed to be the spies and after their mission complete, Aqualad returns to his post as leader once again. Designation : B02. Robin / Nightwing / Dick Grayson ( voiced by Jesse McCartney ) - Known as Robin throughout Season 1 ; Grayson was, though only thirteen, the most experienced member of the team. 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 in order 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, 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 does n'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 ''. 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 remains on the team as their leader and trainer, assigning and participating in missions. Dick encourages Tim to have confidence in his leadership skills, but the latter is apprehensive about doing so. After `` Endgame '', Dick decides to take a leave of absence after Wally 's sacrifice and leaves Barbara in charge if they need any help. Designation : B01. Kid Flash / Wally West ( voiced by Jason Spisak ) -- During Season 1, Kid Flash is the team 's sixteen - year - old speedster. He has enhanced speed, although he has not fully mastered his abilities, often falling down while running at high speeds due to a misstep. Kid Flash can not vibrate his molecules through solid objects like the Flash and gets a bloody nose if he attempts to. He is a flirt, beginning with M'gann and extending to any woman he comes into contact with. Kid Flash and Robin know each other outside the team, even knowing each 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. Ava Dordi, of the Palo Alto Voice notes that Jason Spisak `` captures the Lighthearted essence of Kid Flash well ''. 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 return to the mission during `` Bloodlines '' to stop Neutron and resume back into the team during `` Summit ''. During `` Endgame '', he with Flash and Impluse manage to control the Magnetic Field Disruptor but due to his slower speed, the chrysalis ' energy attacks him, causing him to disappear. Designation : B03. Superboy / Kon - El / Conner Kent ( voiced by Nolan North ) -- 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, and later : infrared vision. 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 becomes romantically involved with M'gann while under cover in Belle Reve. Sometime between Season 1 and Season 2, Superboy ended their relationship due to M'gann using her telepathic powers to violently extract information from enemies ; even more so, that she tried to tamper with his mind to make him try to forget that they had argued about it. 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. Greg Weisman notes that Nolan North provides `` good separation '' between the dual roles he portrays as Superman and Superboy. Designation : B04. Miss Martian / Megan Morse / M'gann M'orzz ( voiced by Danica McKellar ) -- Miss Martian is Martian Manhunter 's teenaged ( by Martian standards, though she is in her 40 's in earth years ) niece, as well as being an inexperienced superhero. As a Martian, she has telekinesis, telepathy, and flight. Additionally, she can shape - shift to a limited extent. She has stated that she can not become intangible as her uncle can, implying that this is an advanced skill ; but by Season 2, she had learned this power. 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. '' Sometime in the five - year lapse between Season 1 and Season 2, Superboy ended their romantic relationship because he does not outwardly age, as well as M'gann 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 '', and at some point attempted to make him forget he was upset. 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. However, after some thinking, she breaks up with Lagoon Boy during `` Interventions '' and later repair her relationship with Superboy. Designation : B05. Artemis / Tigress / Artemis Crock ( voiced by Stephanie Lemelin ) -- Artemis was the team 's fifteen - year - old archer. 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 is n'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. 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. 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. Designation : B07. Expanded members The following members were added to the team after the series premiere at different times : Zatanna Zatara ( voiced by Lacey Chabert ) -- The daughter of Justice League member Zatara, she first appears in `` Humanity '' and sporadically through the later episodes. She permanently moves into Mount Justice in the episode `` Misplaced '' after her father becomes the new Doctor Fate, and is an official member of the team. Her powers, like her father 's, are magical, and like her father 's, her spells are spoken in reverse order. Sometime during the five - year lapse between Season 1 and Season 2, she has joined the Justice League. Designation : B08, later 25. Speedy / Red Arrow / 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, recovering in a hospital in Star City 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. Designation : B06, later 21.

Beast Boy / Garfield Logan ( voiced by Logan Grove ) - In the Season 1 episode `` Image '', Garfield lives with his mother Marie who runs the Logan Reserve around the borders of Bialya and Qurac. In this episode, it is revealed that Marie Logan once starred in a television show called Hello Megan ! that inspired Miss Martian 's human guise and her catchphrase. Garfield is hurt when Queen Bee 's jets attack and needs a blood transfusion to survive following him freeing the sick oryx and an injured wildebeest from the barn. Miss Martian changes her blood type to O negative in order to save Garfield 's life. He is saved, but his blue eyes at the time turned green. Sometime before the events of Season 2, Garfield 's skin turned green and he developed the ability to shape - shift into animals ( ergo, the name Beast Boy ) with his hero disguise having monkey - like features. In `` Earthlings '', it is revealed that Queen Bee caused the car accident that killed Garfield 's mother. In the same episode, he is shown to be somewhat careless about blood loss, wondering if he 'll get a new power from another transfusion of M'gann's blood. Designation : B19. Blue Beetle / Jaime Reyes ( voiced by Eric Lopez ) -- Sometime during the five - year lapse between Seasons 1 and 2, he joined the Team. 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. The scarab decides to work with Jaime as equals, preferring it over enslavement to the Reach. Designation : B22. 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.

Guardian / Mal Duncan ( voiced by Kevin Michael Richardson ) -- The boyfriend of Karen Beecher and classmate of Superboy and Miss Martian at Happy Harbor High School.

He recites lingo from the future ( `` feeling the mode '' ). He came to their time to avert a disaster by a future Neutron. Although Bart was able to cure Neutron, he pretended that he was unable to return to his own time which was still devastated from an as - yet - unknown event. It is revealed in `` Before the Dawn '' that a Blue Beetle has enslaved the human race, an event that Bart is trying to change by keeping him out of the clutches of the Reach.

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 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. This caused him to take up the offer to allies with the meta - humans Luthor had previously employed.
