Slade Wilson was always strong and determined. He lied about his age so he could join the army and quickly distinguished himself as one of the youngest decorated soldiers. During a training session in guerrilla warfare, his trainer, Adeline Kane, bested him. Her fiery personality and superior fighting skills fixated Wilson and they quickly fell in love and married. Shortly after Adeline gave birth to the couple's first son, Grant. Slade continued active duty and volunteered for a medical experiment in resisting truth serums. In reality this was government testing, aiming to create meta-humans from normal humans. The experiments left Wilson bedridden until he recovered. The experiment gave Wilson enhanced strength and heightened reflexes. After Wilson's recovery, his second son, Joseph, was born. Wilson was later discharged from the army after rescuing his friend, Wintergreen, despite his orders to the contrary. Taking up hunting, Wilson was unable to satisfy his hunger for action and so he took up a secret mercenary lifestyle. Unbeknownst to his family Wilson became Deathstroke, the Terminator.
One of his first missions saw Deathstroke assassinate a Colonel from the country of Qurac. The Quraci President sent a terrorist known as the Jackal to find Deathstroke and work out who employed him. The Jackal kidnapped Joe Wilson, forcing Deathstroke to admit to Adeline that he had a secret life. Adeline confronted the Jackal along with Deathstroke. Deathstroke refused to give Jackal the information he was after, believing himself fast enough to save his son. He accomplished this but not fast enough as one of the Jackal's men had begun to slit Joseph's throat, rendering him mute. Adeline confronted Deathstroke once the family was safe and tried to shoot him. Deathstroke's reflexes saved his life but were not fast enough to avoid the bullet which took his right eye. Adeline then divorced Deathstroke and raised her two sons alone. Grant decided to follow in his parents' footsteps and enrolled in military school but Joseph was different. Adeline nurtured his artistic and musical side, raising him as a considerate young man.
Deathstroke continued his activities as a mercenary, using a personal code of ethics which limited his jobs to those which his conscience allowed. A few years following his divorce, Deathstroke met an Oriental clan princess names Lillian Worth. Finding her life in ruins, "Sweet Lili" was rescued from war torn Cambodia by Deathstroke and taken to Thailand where she had a freedom of sorts. Remaining in contact, the two embarked on a hot and cold love affair whenever their paths crossed. During one such meeting, Lili feel pregnant and later gave birth to Rose Worth, keeping the child a secret from Deathstroke realising it was in the child's best interests to keep her from a mercenary's life.
After forging a successful career as Deathstroke the Terminator, Wilson's reputation was such that he could pick and choose his jobs. One job which he casually refused changed his life forever. The criminal organisation H.I.V.E. (Hierarchy of International Vengeance and Extermination) offered Deathstroke a contract to kill the Teen Titans. Refusing the offer, H.I.V.E. then hired Deathstroke's son, Grant, to assume the contract himself. Grant was bitter and convinced that the Titans had ruined his life after Starfire accidentally destroyed his apartment and then Starfire and Wonder Girl chased him away from his ex girlfriend's apartment when he got abusive. Seeing the contract as a means of revenge, Grant was given powers and a costume and called himself the Ravager. Failing in his bid to destroy the Titans, Grant's body couldn't handle the powers that had been placed in it and he died in his father's arms, withering to nothing. Deathstroke vowed to complete his son's contract, exactly what H.I.V.E. were planning when they hired Grant as they knew his body wouldn't handle the powers they gave him.
Failing on his own, Deathstroke began an affair with Tara Markov, a teen sociopath with dangerous earth shaping powers. Being emotionally unstable and seeing Deathstroke as a bizarre father figure come older love interest, Markov infiltrated the Teen Titans on Deathstroke's orders and learned all of their secrets and weaknesses. Deathstroke succeeded in capturing all of the Titans except Nightwing and delivered them to H.I.V.E. The team were rescued by Nightwing with the assistance of Joe Wilson, calling himself Jericho. In the ensuing battle, Terra died and Deathstroke was captured to stand trial. The case was thrown out of court when the prosecutor failed to prove that the Terminator who captured the Titans was actually Slade Wilson. In actuality the trial was sabotaged by Changeling who wanted to destroy Deathstroke himself for corrupting Terra. Deathstroke turned up for their arranged confrontation out of costume, forcing Changeling to see that he was a man and not a faceless mask that he could take out his rage on. Parting after a truce Slade laid low and started hunting in Africa.
Months later, Slade was involved in a Titans' case concerning a dangerous plague he became active as Deathstroke once again, resuming his mercenary status and using a stricter code of ethics. When current and former members of the Titans were hunted down and captured by the mysterious Wildebeest Society, Deathstroke joined Nightwing in forming a strike force designed to discover the missing Titans. Proving crucial in tracking the missing Teens, Deathstroke was horrified to learn that the leader of the Wildebeest Society was his own son, Joe Wilson. When the souls of Azarath had merged with Jericho they forced him to acquire super humans to serve as hosts for them. During the soul transfer process Jericho's real soul emerged and pleaded to his father that Deathstroke kill him so that the souls of Azarath would be destroyed and the Titans would be saved. Wanting to spare his son anymore pain as well as saving the Titans, Deathstroke drove his sword through his son, killing him instantly.
Now carrying the guilt surrounding both his sons' deaths, Deathstroke continued his mercenary career but also acted as a hero in memory of Joe. At times he even aided the Titans as well as others requiring his assistance. During this time Deathstroke met Pat Trayce, a former cop, and quickly became her lover and began a relationship like his previous ones which was both steamy and fleeting. Deathstroke's life was later turned upside down when he prevented an assassination attempt on the President by a doppelganger of a U.S. Senator. The authorities believed that Deathstroke had murdered the Senator in an attempt to take the President's life. Deathstroke was forced to live the life of a fugitive. Not only was he hunted by the government but a new man calling himself Ravager appeared, hunting down Slade's former friends and lovers, killing his informant Maurice, his tech supplier Squirrel and the mother of his daughter, Lili. Adeline was also starting to exhibit new behaviour, blaming Deathstroke for the death of her sons and vowing to kill him and Pat Trayce. Working with Sarge Steel and the organization Checkmate, Deathstroke cleared his name and proved that the assassination attempt was actually the work of the Crimelord, Steve Dayton. Dayton intended to replace all the world leaders with clones that he controlled. He also wished to merge his essence into cyberspace making him in control of everything. Deathstroke thwarted Dayton's plans and left him stranded in the void of cyberspace.
However, during the ordeal Deathstroke was riddled with bullets and brought to a morgue. He was understandably shocked when he awoke from the dead. It appeared that Deathstroke not only had an enhanced healing factor but also was immortal. Deathstroke discovered though that after waking from each death he was in a state of psychosis for a brief time. Deathstroke also discovered the existence of his daughter. Leaving Rose in the care of Wintergreen as he still saw himself as a bad parent, Deathstroke also discovered that the new Ravager was his half-brother Wade DeFarge. Being insanely jealous of his half brother, DeFarge tried to torture Deathstroke by killing all the people that Slade cared about. Meanwhile Adeline Kane had gone completely insane and donned a Vigilante costume, coming into conflict with Deathstroke and Ravager, Adeline was wounded but healed immediately. Deathstroke realised that the forced blood transfusion he had to give to Adeline had transferred is powers into her but was also driving her mad. Whilst fighting Ravager, Adeline was shot between the eyes and presumed dead. The Ravager was captured and taken away by the authorities whilst Adeline awoke in the morgue, leaving without anyone knowing.
