As shown in the episode "Go",^[1] Robin formed the group after aiding Starfire in her escape from captivity with help from Beast Boy, Cyborg, and Raven. Prior to this, he left his mentorBatman to become an independent crime-fighter. TheTeen Titans Go! spin-off comic reveals he isDick Grayson, the first Robin, but this is not depicted in the series (Though there are several hints such as Larry's name being Nosyarg Kcid, him becomingNightwing in the future, and Raven witnessing his parents' death at the circus in "Haunted"). Robin is best friends with Starfire, whom he secretly has romantic feelings for. Their relationship develops throughout the series, with them becoming a couple in the finale filmTeen Titans: Trouble in Tokyo.

Cyborg (voiced byKhary Payton) is an African-American human who was converted into a cyborg to save his life following an unspecified accident.

Raven (voiced byTara Strong) is the gothic half-demon daughter ofTrigon andArella. She possesses vast magical abilities and was intended to act as Trigon's portal to invade Earth. While he succeeds in doing so, Raven works with the Titans to defeat him.

Beast Boy (voiced byGreg Cipes) is a former member of theDoom Patrol who can transform into any animal.

In an issue oftheTeen Titans comic book following the events of the series' final episode,Geo-Force — Terra's superhero half-brother — makes an appearance in which he reveals that Terra, like he, is a member of the royal family ofMarkovia who fled their home nation after they were both subjected to forced experimentation that gave them both earth-manipulating superpowers. Geo-Force is later convinced to leave Terra alone and leaves without ever reuniting with her.

The ex-sidekick of Aquaman,Aqualad (voiced byWil Wheaton) makes his debut in the episode "Deep Six",^[9] employing the help of the Teen Titans in defeating an Atlantean criminal named Trident. He butts heads with Beast Boy in that episode as he feels shown up by the impressive young Atlantean, but in their battles with Trident, Beast Boy and Aqualad make peace by the episode's end. He returns in "Wavelength",^[10] needing the Titans' help to take out Brother Blood's second underseaH.I.V.E. headquarters. Following Blood's escape, they give chase and track him to Steel City, where he and Bumblebee form theTitans East. He later falls prey to Blood's mind control, turning on appointed leader Cyborg and does battle with Titans Central; he is freed after Cyborg defeats Brother Blood in the final battle, and stays on with Titans East.

Argent (voiced byHynden Walch) is a female Honorary Titan who first appears in "Calling All Titans".^[11] Deputized by Starfire while walling off a fractured dam, she is soon attacked and captured by General Immortus and flash-frozen at theBrotherhood of Evil's headquarters in Paris. She is later freed and takes part in the final battle of "Titans Together",^[12] briefly seen in the background fighting Johnny Rancid, and standing near the foreground at the episode's conclusion when the Titans are summoned to stop Doctor Light.

Bumblebee (voiced byT'Keyah Crystal Keymáh) is introduced as a H.I.V.E. student, but is later revealed to have been a spy in the organization working in league with Aqualad. As she reveals in a staged fight with Cyborg, she is immune to Brother Blood's hypnotic influence. She later becomes a founding member of Titans East, convincing Cyborg to become the team's leader, when in fact it turns out to be an elaborate trap staged by Blood when she falls back under his control—though she appeared to be the only one of the group able to occasionally slip free. After Blood is defeated, Cyborg steps down from Titans East, making Bumblebee the new leader.

Bushido is a young silent Japanese swordsman, who is made an Honorary Titan to fend off an incursion by the Brotherhood of Evil, which is preparing to mount an assault on young heroes.^[11]

Gnarrk (voiced byDee Bradley Baker) is a caveman friend of Kole seen in the episode "Kole".^[13] He is given his name due to the fact that it is the only thing he can say or understand.

When Kole activates her crystallization powers, Gnarrk is able to use her body to great effect as a bludgeoning tool.

Herald (voiced byKhary Payton) is a young hooded African American boy who is made an Honorary Titan in the wake of the Brotherhood's efforts to seek and destroy the next generation of superheroes on Earth. He is one of the few Titan-affiliated heroes that manages to evade capture, and partners with fellow survivors Beast Boy, Más, Pantha, and Jericho.

Jericho is another honorary titan who, alongside Herald, is summoned to the Titans' rendezvous point after the Brotherhood conducts their search-and-capture campaign on the team members across the globe. Jericho is a gentle and kindly albeit mute boy with the ability to possess others via eye contact, taking full control of their bodies, memories, and abilities; the only evidence of which is the black and green eyes the victims assume once possessed.^[12]

Thunder and Lightning (respectively voiced byS. Scott Bullock andQuinton Flynn) are the first honorary Titans to appear in the series; they debut in "Forces of Nature",^[19] and are brothers with power over their namesakes. They arrive from the clouds, wreaking havoc on the city in which the Teen Titans live; Beast Boy later deduces that the duo is not evil, but rather misunderstood—they display their destructive powers in acts that they perceive as innocent fun, and battle the Titans on occasion, seeing the challenge as mere roughhousing. The two are later manipulated into creating a fire creature by Slade, who is in the guise of an Asian shaman; however, the two learn the error of their ways thanks to Beast Boy and go on to become heroes allied with the Titans.

Aqualad's engineer, mechanic and friend,Tramm (voiced primarily byDave Coulier and byDee Bradley Baker in the episode "Calling All Titans") helps the Titans fix their battle-damaged T-Sub in the episode "Deep Six".^[9] He speaks in an indecipherable undersea language and has the appearance of a short, anthropomorphicanchovy. In combat, he can increase his size and strength, much like apufferfish.

Wonder Girl also appears in the tie-in comicTeen Titans Go!, where she is identified asDonna Troy.

Brushogun (voiced byCary-Hiroyuki Tagawa) was formerly a Tokyo artist who fell in love with a woman he drew. He used black magic to bring her to life, and it worked, but he was cursed by the magic, turned into a monstrous being with the ability to create living ink drawings. General Uehara Daizo kidnaps Brushogun and forces him to battle the Teen Titans, during which he is killed.^[24]

Elasti-Girl (voiced byTara Strong) has the ability to expand her body and grow to a giant size; though it consequently makes her an easier target that is harder to miss, an attack as benign as a foot stomp can level an entire field of enemies merely from the shock wave.

Mento (voiced byXander Berkeley) is the leader and battle coordinator of the Doom Patrol. His uniform signifies as such by way of a yellow lightning-bolt symbol on its chest. Amplified by the helmet atop his head, Mento's super-abilities stem from his formidable mental powers, ranging from telekinesis and mind-reading to quick-acting hypnotic suggestion.

Negative Man (voiced byJudge Reinhold) has the power of astral projection; able to separate his soul from his body, his "negative self" has targeted intangibility: enemies cannot harm him while in this state, though he can physically interact with solid objects and people. However, this separation ability can only work for a limited time, as extended use of it could lead to its effects being permanent.

Robotman (voiced byPeter Onorati) is a towering metal robotic vessel housing a still-living human brain; as such, he has immense strength and is practically invulnerable to harm. However, still capable of free thought, Robotman is headstrong and reckless, often preferring to charge headlong into battle than defer to stealth.

Larry (voiced byDee Bradley Baker) isRobin'sBat-Mite-like counterpart from another dimension. His right index finger has the power to bend reality, and he uses it to watch Robin and his adventures. He enters the Titans' dimension to help fix Robin's broken arm, but fails to do so. He breaks his own finger during a scuffle with Robin as he keeps insisting on helping him; as a result, his reality-warping power is unleashed upon the city, changing it first into an embodiment of a child-drawn picture, and later into a dark, demonic domain when Titans foe Johnny Rancid seizes the power for himself. After Larry's finger is repaired and all is brought back to normal, he returns to his own dimension, but not before Robin offers him the chance to fix his broken arm one last time. He succeeds, but accidentally leaves Robin stranded in a blank, white space in the process.

Silkie (voiced byDee Bradley Baker) is one of the many mutant larvae created by Killer Moth as part of his scheme to take over the city in "Date With Destiny". When he was stopped by the Teen Titans, Beast Boy bonded with one of the larvae, naming him "Silkie", and secretly kept him as a pet at Titans Tower.

Slade (voiced byRon Perlman) is the Titans' most recurring foe and Robin's archenemy. Slade relentlessly stalked them since "Divide and Conquer" and enlisted the H.I.V.E. Academy to reveal his existence to the heroes in "Final Exam".^[26] Serving as the main antagonist of the first two seasons, Slade attempted to make Robin his apprentice in the first season and later enlisted Terra during the events of the second in an attempt to destroy the Titans that ended with his death. Slade is revived in the fourth season as Trigon's undead emissary to oversee the ritual to summon the demon, siding with the Titans and fully resurrecting himself when Trigon betrayed him before taking his leave.

Trigon (voiced primarily byKevin Michael Richardson and byKeith Szarabajka in the episode "Nevermore") is Raven's father and archenemy who is feared throughout the galaxies as an ancient demon king.

Brother Blood (voiced byJohn DiMaggio) is a cult leader and the archenemy of Cyborg, who takes control over the H.I.V.E. Academy after the Headmistress disappears; his power is based mainly on his ability to manipulate others through mind control, bending large groups of people to his will. Aside from purehypnosis, his mind can create vivid hallucinations, and he also boasts both a vast intelligence and aphotographic memory. Blood's mental powers also allow him to interfere with radio signals and block the powers of other empaths likeAqualad; they also greatly enhance his own physical abilities: Blood is deceptively strong and quick with supernaturally high reflexes, allowing him to walk across water, pierce and rip steel with his bare hands, and channel a psychokinetic energy used to teleport or to fire offensively as bolts of lightning and force blasts.

TheH.I.V.E. Headmistress (voiced byAndrea Romano) is the unnamed headmistress of the H.I.V.E. Academy in the first season.^[26]

Gizmo (voiced primarily byLauren Tom and byTara Strong in the episodes "Revved Up" and "Titans Together") is an impish young boy with a genius-level intellect who is armed with a mechanized backpack that generates multiple devices, gadgets and weapons.

He is brought into the original H.I.V.E. trio as a counterweight to Beast Boy. The genetically modified Mammoth is the least intelligent member of this clique and is mainly used for his brawn and raw power in the execution of H.I.V.E. crimes. In spite of this, he tends to be easily defeated by the Titans in most of the episodes in which he appears.

See-More (voiced byKevin Michael Richardson) is a villain from the H.I.V.E. Academy who joins the H.I.V.E. Five prior to "Mother Mae-Eye".^[27] His powers stem from a variety of interchangeable colored eyeballs which are accessible via a dial in his helmet; each eyeball is equipped with a unique function or attack, such as multi-vision, X-Ray vision, hypnosis, projection of eye-shaped bubbles, laser beams, and balloon-based flight.

Billy Numerous (voiced byJason Marsden) is a villain and student at the H.I.V.E. Academy; like many of the H.I.V.E. characters, Billy Numerous first appears in the cafeteria scene in the episode "Deception".^[28] His power is self-duplication, and he is known to brag about his crime sprees to his only friends: his own clones. He wears a skintight red bodysuit with a division symbol on its chest, and speaks with a rural Southern drawl.

Kyd Wykkyd is a silent, bat-costumed male student at the H.I.V.E. Academy with the ability to teleport, first seen in "Deception".^[28] After Cyborg and the Titans destroyed H.I.V.E. and the various students went on to become renegade villains, Wykkyd joined the H.I.V.E.

Brain (voiced byGlenn Shadix) is the leader of the Brotherhood of Evil. As suggested by the name, he is a disembodied human brain preserved in a robotic cylinder to keep it alive, only able to communicate via a voice box built in its chassis. Apart from the Brain's genius level intellect, he appears to have a degree of psychokinetic powers channeled by and through his robotic shell.

General Immortus (voiced byXander Berkeley) is an ancient military commander who is knowledgeable in every combat strategy ever conceived, mainly by being involved in every major battle in history personally. He even comments on teaching many of history's best minds of war; in the episode "Homecoming",^[3][4] he refers toSun Tsu—the Chinese military philosopher and author ofThe Art of War—as one of his students. Immortus has command over armies of both human and robot soldiers, and often uses them as part of a larger plot in executing attacks.

Madame Rouge (voiced byHynden Walch) is a European shapeshifter and member of the Brotherhood of Evil. Rouge is a malleable shapeshifter with the ability to stretch and contort her body in any way she sees fit; she is most lethal for being able to fully assume the appearances of other people, able to mimic them with little means of detection.

Monsieur Mallah (voiced byGlenn Shadix) is a hyper-intelligent African gorilla capable of human speech who develops many of the Doomsday Devices used by the Brotherhood.

Uehara Daizo (voiced byKeone Young) appears as the main antagonist in the feature-lengthTeen Titans film,Teen Titans: Trouble in Tokyo.^[24] He isTokyo's police commander, and the commander of the Tokyo Troopers, which he secretly uses Brushogun in creating. It turns out that Daizo's goal is to discredit the Teen Titans as heroes, as his own heroic reputation became diminished as the Titans' exploits become internationally known. To this end, Daizo enslaves Brushogun to create criminals for him to capture, to create the Tokyo Troopers to act as his personal army, and creates supervillains to do battle with the Teen Titans.

Control Freak (voiced byAlexander Polinsky) is an overweightsupervillain and film fanatic, notorious for using a nuclear super-powered remote control to warp reality to suit his film inspired images. The remote he self-designed is his only true source of power, but he rarely uses his intellect to accomplish anything meaningful, instead preferring to hype himself into superiority in hopes of garnering mass respect as a supervillain.

Ding Dong Daddy (voiced byDavid Johansen) is a large1950s-style street racer who forces Robin to compete in a cross-country race against himself and several foes from the Titans' rogues gallery.

He wields a moth-like body armor equipped with razor-sharp claws and a pair of wings that gives him an elevated level of speed, strength and reflexes, has the ability to adhere to walls, as well as flight.

Kitten (voiced byTara Strong) is the spoiled and bratty daughter of Killer Moth and the girlfriend of Fang. She first appears in the episode "Date With Destiny", when Fang breaks up with her for unexplained reasons. Not wanting to attend thejunior prom alone, she talks her father into threatening the city with a large swarm of mutant moths to force Robin to become her date, which instigated a fight between Fang and Robin, and then between Kitten and a jealous Starfire. It would be revealed that Kitten secretly had control of the moth's release trigger concealed in hercorsage, but she, Fang, and Killer Moth are ultimately apprehended and jailed; as she is loaded into the police truck, she angrily screams that Robin would pay for dumping her. In the fifth season, Kitten appears as a member of the Brotherhood of Evil, riding atop a giant mutant moth and wielding a laser whip.

Mad Mod (voiced byMalcolm McDowell) is a psychedelic red-headed British villain with the mannerisms of a strict schoolmarm, whose root source of power comes from his ruby-tipped cane.

Mae-Eye feeds on the affection of her victims; she then traps and bakes them within a gigantic pie.

After overcoming their issues in controlling the other's powers, Raven and Starfire work together to stop him, and the Puppet King's spells are broken as the Titans' souls are returned to their proper bodies.
