In the first season, Dick leaves Bruce to become a police detective in Detroit and forge his own path. He encounters Rachel Roth seeking his help, which leads to them also meeting Kory Anders and Gar Logan.

In the second season, after being rescued by Rachel, Dick leads a new Titans team with her, Gar, and Jason Todd. It is also revealed that Dick was part of an earlier Titans team with Donna, Hank Hall, and Dawn Granger that disbanded when Dick's revenge plot against Deathstroke, who killed their teammate Garth, resulted in the death of Deathstroke's son Jericho. The reemergence of the Titans causes Deathstroke to come out of retirement, forcing Dick to admit to his team that Jericho sacrificed himself to save Dick instead of already being dead by his father's hands when Dick found him. Afterwards, Dick learns that Jericho is still alive, but trapped inside of Deathstroke's body.

Koriand'r, often referred to as "Kory Anders", is an extraterrestrial royal from the planet Tamaran. In addition to having enhanced strength and durability, she can absorb and redirect heat energy, although this causes her powers to be weakened without the sun. Kory begins the series next in line to her planet's throne, despite being uninterested in claiming it.
In the first season, Kory is sent to assassinate Rachel on Earth over fears that Rachel's summoning of her demon father Trigon will put Tamaran in danger. However, Kory suffers a bout of amnesia that causes her to instead befriend Rachel and join Dick and Gar in protecting her, leading to them rescuing Rachel's mother Angela Azarath. Kory later has her memories restored by Rachel, which allows her to find her spaceship and information on her original mission. This information helps Kory, Dick, and Donna Troy learn about Trigon and Angela being in allegiance with him. Nevertheless, they are unable to prevent Trigon from being summoned.
In the second season, after Trigon's defeat, Kory teams up with Donna to fight crime in Chicago until she is captured by her former bodyguard and lover Faddei. Faddei informs Kory that he was ordered by Blackfire to return her to Tamaran to claim the throne, but Kory escapes him to assist the Titans in fighting Deathstroke. She subsequently learns from Faddei that Blackfire claimed the throne after killing their parents and is now hunting her; Kory is also forced to kill Faddei when Blackfire takes over his body. Although promising to hunt down her sister, Kory prioritizes helping the Titans defeat Lex Luthor's Cadmus Laboratories and subdues their leader, Mercy Graves.

In the first season, Rachel begins to learn about herself while being targeted by Trigon's associates because of her role in summoning him. She seeks the help of Dick Grayson when he appears to her in her dreams and the two team up with Kory Anders and Gar Logan, leading to them reuniting Rachel with her biological mother, Angela Azarath. However, Angela is revealed to be in allegiance with Trigon and forces Rachel to summon him under the threat of killing Gar.
In the second season, after defeating Trigon, Rachel joins a new Titans team with Gar and Jason Todd under Dick's tutelage. Although Rachel believes her father is dead, she continues to feel his influence while her powers become more unstable. She helps defeat Lex Luthor's Cadmus Laboratories by using her powers to allow Dick to break Conner's brainwashing. After Donna Troy is killed, Rachel travels to the Amazons' home of Themyscira, believing her powers are capable of bringing Donna back. In her absence, Kory and Dawn Granger speculate that Rachel created an illusion of Bruce Wayne that they witnessed.

Garfield "Gar" Logan is a shapeshifter who can transform into animals of his choice. He primarily turns into a tiger, his favorite animal. Gar developed his abilities from a drug administered by scientist Niles Caulder, also known as the Chief, to cure him of a lethal disease. The drug saved his life, but also created the side effect of allowing him to alter his DNA into animal DNA. He begins the series living in a secluded mansion with the Chief and other individuals saved by him.
In the first season, Gar encounters Rachel Roth while sneaking out of the mansion and encourages her to live with him. After Dick Grayson and Kory Anders arrive to take back Rachel, Gar's housemates encourage him to join them. He becomes part of a team with Dick, Kory, and Rachel, who defeat those pursuing Rachel and reunite her with her mother Angela Azarath. However, Gar ends up poisoned by Angela, who is secretly in league with Rachel's demon father Trigon. To save Gar's life, Rachel is forced to summon Trigon, and Trigon cures Gar of his poisoning.
In the second season, after Trigon's defeat, Gar joins a new Titans team with Rachel and Jason Todd under Dick's leadership. Gar is the only Titan who does not leave their tower after Dick reveals the truth behind Jericho's death, which results in him being left alone to care for Conner. He is subsequently captured by Lex Luthor's Cadmus Laboratories, who subject him to a brainwashing experiment that causes him to turn violent on command. The experiment is intended to increase Conner's bidding rights by pitting him against the brainwashed Gar, but Rachel manages to save Gar as the Titans defeat Cadmus.

When he tries it out, he blacks out before regaining consciousness in the wrecked lab. Gar was told by Bernard Fitzmartin that he became a gorilla, a Velociraptor, and an armadillo. He once became a virus in order to deal with a snake that Mother Mayhem put in Superboy's body.
Main article: Jason Todd
Jason Todd is a vigilante who becomes the second Robin under Bruce Wayne, succeeding Dick Grayson. A former street delinquent with a troubled past, he took up the mantle of Bruce's new sidekick after he was caught trying to steal the hubcaps from the Batmobile. As with Dick, he compensates for his lack of superpowers with physical prowess and gadgets, but is significantly more aggressive than his predecessor.
In the first season, Jason tracks down Dick to inform him about Nick Zucco, the son of the mobster who murdered Dick's parents, killing Dick's former circus members. The two Robins team up to defeat Nick, although tensions surface between them after Jason brutalizes a group of police officers. Jason is later sought by Hank Hall and Dawn Granger in helping Dick against Rachel Roth's demon father Trigon.
In the second season, after Trigon's defeat, Bruce removes Jason as his sidekick and reassigns him to be part of Dick's new Titans team. Struggling to fit in, Jason pursues the supervillain Dr. Arthur Light on his own, which results in him nearly being killed by Deathstroke. He later leaves the Titans with Rose Wilson, whom he forms a relationship with. The relationship comes to an abrupt end, however, when Rose admits that she was hired by her father to spy on the Titans, causing a betrayed Jason to head off on his own. Jason is last seen watching Donna Troy's funeral from a distance before he again leaves in solidarity.
In the third season, Jason is told by Bruce that he needs to stop being Robin after his second session with Leslie Thompkins. This leads to him visiting Jonathan Crane for a formula in removing fear. Jason goes after Joker and finds him at Amusement Mile. This was an ambush as Joker beats Jason up with a crowbar. His body was later stolen from the morgue by an unknown person working for Jonathan Crane. Jason turns up alive as the Red Hood thanks to Crane dumping his body into a Lazarus Pit. He begins a plan to ruin the Titans and even offers some gang leaders protection while getting half of their proceeds. Eventually, he comes to regret his actions and plans to arrange for the Titans to apprehend Scarecrow which goes south when Tim Drake is shot. After regretting his action, Jason turns against Crane. Upon being offered to help him by a revived Dick, Jason is told that he would not be a Titan again. After making up with Bruce and before he leaves Gotham City, Dick is told by Jason to forward his forgiveness to the rest of the Titans.
Main article: Donna Troy
Donna Troy is a half-Amazon who shares the enhanced physical strength, speed, and durability present in her race. She lived away from the Amazons' home of Themyscira with a human father until he was killed by a fire in their apartment.

Donna also befriended Dick Grayson at an early age due to their mutual status as sidekicks. Their friendship led to them forming the original Titans team.
In the first season, Donna has become an investigative photojournalist, but joins Dick in protecting Rachel Roth when she uncovers that Kory Anders' original mission was to assassinate Rachel. After saving Rachel from a temporarily unstable Kory, Donna discovers information on Kory's ship about Rachel's demon father Trigon, which unveils that Rachel's mother Angela Azarath is in league with him. This revelation, however, comes too late to prevent Rachel from summoning her father.
In the second season, after Trigon's defeat, Donna and Kory team up to fight crime in Chicago until the return of Deathstroke brings Donna back to the Titans' base with original teammates Hank Hall and Dawn Granger. It is revealed that on the original Titans team, Donna had mutual romantic feelings for teammate Garth until he was killed by Deathstroke, setting up a chain of events that resulted in the death of Deathstroke's son Jericho and the Titans disbanding. She leaves the team again after Dick reveals that he had a bigger role in Jericho's death than he previously admitted, but rejoins Dawn, Kory, and Rachel when they learn that Lex Luthor's Cadmus Laboratories has captured Gar Logan and Conner. Although both Deathstroke and Cadmus are defeated, Donna is killed in the aftermath by sacrificing herself to prevent a damaged electrical tower from landing on Dawn and a group of civilians. Despite this, Rachel pledges to bring Donna back to life while her body is being transported to Themyscira.
In the third season, Rachel has been having a hard time reviving Donna. In the afterlife, Donna encounters Tim Drake on a train to his "stop" and follows him off the moving train. When a bunch of ghouls attack in order to drag them to Hell, they are saved by Hank. Donna was reluctant to return to the living after finding out how to return. When they reach the bridge to the living, Donna takes Tim across while Hank buys them some time. When Donna is revived, Rachel finds her body gone. Donna then appears in England where she saves Bruce Wayne from an attempted fiery suicide. After a brief sparring with Lydia, Donna makes it to Gotham and assists Tim and his family against the police officers on Jonathan Crane's side.

Main article: Dawn Granger
Dawn Granger is the tactical half of the vigilante duo Hawk and Dove, assuming the latter mantle. Her combat experience derives from her background in ballet. She is the second Dove, succeeding Hank Hall's half-brother Don who was killed in the same accident that took the life of her mother Marie. Dawn was also a member of the original Titans. Although in a relationship with Hank at the start of the series, she was previously dating Dick Grayson on the original Titans team, creating lingering tensions between the three.
In the first season, Dawn is sought by Dick to look after Rachel Roth while she and Hank are planning to retire. The four are later ambushed by the Nuclear Family, who throw Dawn from a building. Dawn is left comatose from the attack until she receives a message from to Rachel to find Jason Todd to help Dick defeat Rachel's demon father Trigon.
In the second season, after Trigon's defeat, Dawn and Hank have retired to a farm in Wyoming, although Dawn continues to operate as Dove. The return of Deathstroke forces them back into the Titans, but they leave again after Dick admits that he had a bigger role in the death of Deathstroke's son Jericho than he had previously told them. After Hank breaks up with Dawn, she rejoins Donna Troy, Kory Anders, and Rachel to rescue Gar Logan and Conner from Lex Luthor's Cadmus Laboratories. In the aftermath of Deathstroke's and Cadmus's defeats, she is left with lingering guilt over Donna sacrificing herself to save her. She ultimately agrees to rejoin Hank as Hawk and Dove without being romantically entangled.
In the third season, Dawn joins the Titans in relocating to Gotham City in light of Jason Todd's death. When it was discovered that Jason turned up alive as Red Hood, Dawn gives into the deal Jason made with Dick to obtain some gold bars from an armored truck in order to get the deactivator for the bomb that Red Hood placed on Hank's chest. Due to a trick from Red Hood, the gun that Jason wanted Dawn to shoot him with was the real activator as the bomb on Hank goes off before Superboy can reach him with a deactivator. This trickery left Dawn devastated as Dick comforts her. Afterwards, Dawn tells Dick that she is leaving for Paris to bunk at her family's house there for a while.
Main article: Hank Hall
Hank Hall is the aggressive half of the vigilante duo Hawk and Dove, assuming the former mantle. He took up crimefighting due to sexual abuse he suffered from his football coach Vincent, with his combat background deriving from his experience as a football tight end.

This led to Hank and Dawn meeting through the same grief support group and becoming the new Hawk and Dove team. He and Dawn have had an on-and-off-relationship, with Dawn dating Dick Grayson while they were all part of the original Titans team, causing lingering tension.
In the first season, Hank is plotting his retirement with Dawn when Dick returns to have them look after Rachel Roth. Before further conflict can surface between Hank and Dick, the four are attacked by the Nuclear Family in a battle that leaves Dawn comatose. Hank remains by Dawn's side until she awakens and informs him that they need to find Jason Todd in helping Dick defeat Rachel's demon father Trigon.
In the second season, after Trigon's defeat, Hank and Dawn have retired to farm in Wyoming until Deathstroke's return forces them back to the Titans. They leave again once Dick reveals his bigger role in the death of Deathstroke's son Jericho, only for Hank to break up with Dawn over a belief that they only cause others harm while they're together. He ends up relapsing into drug addiction while working as a cage fighter, but returns to help Dawn against Lex Luthor's Cadmus Laboratories, and the two agree after Deathstroke's and Cadmus' defeats to continue as Hawk and Dove without being in a romantic relationship.
In the third season, Hank was seen as a bicycle-riding police officer in Washington DC when he hears that Dawn and the rest of the Titans are in Gotham City. When he tries to confront Red Hood, he gets subdued and gets a Wayne Enterprise bomb placed on his chest. While Superboy works on a deactivator, Dawn tries to take care of Hank as he starts to prepare for the worst. Due to a trick by Red Hood, Dawn pulls the trigger on the gun that Red Hood lied about shooting him with causing the bomb to go off on Hank before Superboy can reach him with the deactivator. Hank's death left Dawn devastated. When Tim Drake and Donna Troy were in the afterlife, Hank saves them from the ghouls that plan to drag them to Hell. Using some information he obtained, Hank takes them to an upside down tree where a bridge back to the living is. During the next attack by the ghouls, Hank buys them time to get away when the bridge starts breaking while having Donna forward a message to Dawn. After fighting off the ghouls, Hank is reunited with Don as they work to keep people safe from the ghouls.

He received his abilities from participating in a H.I.V.E. experiment and was the experiment's only surviving subject.

When a fight between Deathstroke and Dick ended with Jericho jumping in front of his father's blade to save Dick, the two agreed to keep the circumstances of Jericho's death a secret. Initially unbeknownst to Dick, however, Jericho survived by entering his father's body and Deathstroke has kept him trapped inside over the following four years.
In the second season, Deathstroke comes out of retirement when he learns that the Titans have returned. Aided by his daughter, Rose Wilson, Deathstroke forces Dick to confess the circumstances behind Jericho's death, which causes Dick's team to abandon him. This leads Deathstroke to declare victory over Dick, but warns him that he will kill the Titans if they reunite; a promise he takes action on after Donna Troy, Dawn Granger, Kory Anders, and Rachel Roth team up to save Gar Logan and Conner from Lex Luthor's Cadmus Laboratories. However, Dick, learning the truth about Jericho, prevents Deathstroke from killing his teammates under his new Nightwing identity. Deathstroke's defeat occurs when Rose turns against him, killing her father while Jericho escapes into her body.

In the second season, Rose successfully infiltrates the team by claiming she wants her father dead to avenge her half-brother Jericho's demise. She also succeeds in creating tension among the Titans, which leads to them disbanding after Dick Grayson is forced to admit the true circumstances of how Jericho died. However, Rose's mission becomes compromised when she develops romantic feelings for Jason Todd, who leaves her when she confesses her true role to him. This prompts Rose to turn against Deathstroke, killing him while Jericho escapes from their father's body into hers. Afterwards, she joins the new Titans team.
Main article: Superboy (Kon-El)

The name "Conner" is adopted by him from the nametag of a uniform he takes while escaping from the laboratory. Conner possesses the abilities of both Superman and Luthor, in addition to their personality traits and memories. As a result, he often struggles to control the impulses of his DNA hosts while trying to become his own individual. Because of Conner's human/Kryptonian hybrid physiology from his genetic samples he displays not only their personality traits such as Lex's anger and Superman's altruism, but also their abilities. As such, Conner inherited the genius level intellect of Lex in sciences and technology. Although he can still at times be very naïve due to technically being the chronological age of an infant despite being artificially aged to the physical age of a young adult. In addition to inheriting Lex's intelligence, Conner has also been passed down Superman's Kryptonian superpowers. Due to this, Conner posses abilities such as electromagnetic spectrum vision, heat vision, super strength, speed, stamina, breath, invulnerability etc. Because of Superman's alien DNA being too complex for Lex's scientists to properly clone, they realized that they needed to add human DNA to properly stabilize Conner. As such, Conner seemingly can't fly unlike Superman and his partial Kryptonian genetic structure makes him vulnerable to Kryptonite and magic like Superman.
In the first season, Conner escapes from Cadmus Laboratories while also freeing Krypto, a dog with Kryptonian abilities.
In the second season, Conner encounters the Titans when he saves Jason Todd from Deathstroke. Hunted by Cadmus personnel, Conner voluntarily surrenders to them when their leader, Mercy Graves, promises to help him control his hosts' impulses.
