Deathstroke, formally named Slade Wilson, is a fictional character and major antagonist of the DC Animated Film Universe; serving as the main antagonist in Son of Batman and the secondary antagonist in Teen Titans: The Judas Contract.
He is a professional mercenary who was originally a high-ranking member of the League of Assassins, but later betrayed and killed their leader Ra's Al Ghul upon discovering that Batman - the ex-fiancé of the latter's daughter Talia - would become his impending heir. Since then, Deathstroke has become a prominent enemy of both Batman and later the Teen Titans when the villain had been hired by Brother Blood to capture the latters - one of whom include Batman's illegitimate son Damian Wayne, who is considerably Deathstroke's archnemesis.
He was voiced by Thomas Gibson in Son of Batman, and the late Miguel Ferrer in Teen Titans: The Judas Contract, who also voiced Shan-Yu in Mulan, Big Boss in Rio 2, and Stretch Monster in Stretch Armstrong and the Flex Fighters.
Son of Batman
Slade Wilson was Ra's Al Ghul's right-hand man and future successor but his actions deemed him unworthy and he was banished. The title of successor was passed onto Ra's Al Ghul's grandson, Damian Wayne.
Feeling denied of his right, he named himself "Deathstroke" and went onto proceeding in staging a coup d'état on the league. He fought with his former master and defeated him. As he was about to finish him off, Damian protected his grandfather and stabbed Deathstroke's right eye. He was rescued by another of Ra's Al Ghul's former henchmen, Ubu. After escaping from Ubu, Deathstroke went to Dr. Kirk Langstrom to work on a project initiated by Ra's to use Langstrom's Man-Bat gene splicing formulas on members of the League. He kidnaps Langstrom's family and Talia Al Ghul as insurance. After Langstrom's daughter gave Damian a message that showed Deathstroke kidnapping Talia and tells Damian to come to his fortress or he will kill her.
After Damian came, he confronted Deathstroke. He was about to kill Damian but Talia interfered by shielding her son and taking the shot herself. Deathstroke chased Damian but Batman arrived and the two fought briefly. Batman defeated him and he fled. Damian going by the name "Robin" fought Deathstroke again and Deathstroke was defeated. His fortress sank to the bottom of the ocean with Deathstroke in it, leaving his fate unknown.
Teen Titans: The Judas Contract
It is revealed that he survived his encounter with Robin and used the Lazarus Pit to heal himself. He upgrades his armor and takes on the contract with the H.I.V.E. to capture the Teen Titans, but to also get revenge on Damian for their last encounter. He discovered a young girl named Terra who was accused of being a witch and before the town could kill her, Deathstroke interfered and saved her. He got her to join him and uses her as a double agent for the Titans and himself (whom she also has romantic feelings for).
When Robin becomes suspicious of Terra, he follows her but ends up being captured by her and Deathstroke. Deathstroke later captures Blue Beetle, Beast Boy and Starfire (Raven was captured by Terra), but he fails to capture Nightwing who fakes his death.
Deathstroke and Terra bring the other Titans to Brother Blood but the machine he had created cannot function without one more Titan. Deathstroke then betrays Terra to him but the Titans are rescued by Nightwing. While the other Titans fight Brother Blood, Nightwing and Robin battle Deathstroke before he is attacked by Terra; she became so angry for his betrayal. She then causes an avalanche which he is buried under, thus leaving his fate unknown once again.
Suicide Squad: Hell to Pay
Deathstroke is seen in a flashback when Bronze Tiger recalls of him murdering his fiancee, Miyoshi.
Deathstroke is portrayed as being cruel and wanting revenge on everyone who betrayed him and whom he fought. He is shown to be treacherous and manipulative like when he betrayed Terra to Brother Blood.
