"The Judas Contract" is a Teen Titans event featuring the secret origins of Deathstroke in the DC Comics. The story revolves around the betrayal of Terra after her revelation as a secret agent. "The Judas Contract" is also noted for the introduction of Deathstroke's ex-wife, Adeline, but more importantly, it introduces his second son Joey Wilson. Immediately following the events of "The Judas Contract", Joey Wilson adopts the code name Jericho and becomes a regular member of the Teen Titans. Adeline Kane remains a stable supporting character and has made frequent appearances in both New Teen Titans and Teen Titans Spotlight. In addition, this storyline presents the first appearance of Dick Grayson under his new costume and code-name Nightwing, having left the legacy of Robin forever behind him..
"The Judas Contract" begins shortly after Dick Grayson and Wally West officially retire from active service. Though no longer calling himself Robin, Dick is still intrinsically involved in Titans activity. The group's most recent protégé Terra Markov, is not a full-fledged Titan, but has certainly won the heart and mind of Beast Boy. None of the Titans suspect that she has been secretly spying on them on behalf of her partner Deathstroke. Terra has been feeding Deathstroke important information regarding the Titans including their secret identities. During a training exercise, the Titans begin to learn how mentally unstable Terra truly is. After enduring numerous playful barbs from Beast Boy, she unleashes a massive attack that nearly cripples him. The other Titans calm her down, but it is Raven who realizes that there is something seriously dangerous about this girl.
Once Terra acquires all of the information she needs, she informs Deathstroke who then systematically takes down each of the Titans. He first strikes at the apartment penthouse shared by Donna Troy and Starfire. He incapacitates Starfire with a high-yield letter bomb, and renders Donna unconscious with a gas mixture that he adds to her darkroom chemicals. He then takes out Cyborg by electrifying a chair in his apartment. The high voltage shorts out Vic's systems long enough for Deathstroke to collect him. He then tries to take down Grayson at his apartment, but is surprised when the one non-powered Titan manages to elude him. Frustrated, he goes to the Hamptons to take down that last Titan, Beast Boy. Boy licks a stack of envelope seals treated with a special poison that renders him unconscious. With all but one of the Titans captured, he brings them to the Rocky Mountain headquarters of his employers, the H.I.V.E. Deathstroke is satisfied that he has completed the contract left behind by his late son Grant, but the H.I.V.E. criticize him for failing to bring them Robin.
Meanwhile, Grayson, having discovered that all of his former teammates have been captured returns to Titans Tower. There he is greeted by Adeline Kane, Deathstroke's ex-wife. She introduces him to her mute son Joey. Adeline tells Dick that Terra is a traitor to the team and has been secretly working with her husband since the moment the Titans first met her. Grayson is incredulous at first, but slowly believes Adeline's story after she provides him a comprehensive history on Slade Wilson and the means by which he became Deathstroke. Adeline's son Joey, a mutant at birth, possesses the power to possess other people, and he is eager to help Grayson rescue the Titans. Realizing that he can never truly retire from super-heroing, Dick adopts a new costume and identity and calls himself Nightwing while Joey is also ready to follow him into battle as Jericho. Adeline then gives the heroes the location of the H.I.V.E. command center.
Nightwing and Jericho go the H.I.V.E. base nestled in the Rocky Mountains. They sneak into the facility and discover that the Titans have been strapped to a giant machine which is slowly siphoning away their life energy. Nightwing and Jericho fight through a horde of H.I.V.E. shock troops but are eventually captured. Deathstroke is surprised to see his son with the Titans and tries to bargain with the H.I.V.E. to let him go. The H.I.V.E. refuses however and Jericho takes this opportunity to possess his own father. Using Deathstroke's body and weaponry, he frees the other Titans and begins fighting the H.I.V.E. Terra is enraged at Deathstroke and feels that his affection for Joey makes him weak. She loses complete control of her sanity and yearns for nothing more than the death of everyone in the room. Beast Boy refuses to believe that Terra has gone bad, and is certain that the Terminator has brainwashed her. Terra's powers rage out of control until finally she causes a mountain of earth and debris to collapse down from the ceiling, killing herself in the process. The Titans bring Terra's body back to New York for burial. The funeral service is small and only the Titans and the Outsiders are in attendance. The Titans let Terra's brother, Geo-Force, believe that she died heroically while fighting the H.I.V.E.
