"You and I are not dissimilar. We're both haunted by our pasts, and the only way to bury that ghost is by forgiving yourself."
—Slade Wilson to Oliver Queen[src]

Slade Wilson (born c. 1968)[1], codenamed Deathstroke by A.R.G.U.S., is a former member of the Australian Secret Intelligence Service and an ASIS unit, the secret mastermind behind the Church of Blood, which he used to recruit individuals for his army, and the mentor-turned-enemy of Oliver Queen. Slade is also the father of Joe Wilson, the potential father of Grant Wilson, and was also very close to Shado before her death, being secretly in love with her despite her affections for Oliver.

Slade was initially an ally of Oliver on the island, where he taught the shipwrecked playboy the majority of his combat skills (which he would later utilize in his crusade as the Arrow). Slade was later injected with an experimental Mirakuru serum after a near-fatal accident, and embarked on a crusade of vengeance against Anthony Ivo for killing Shado. Slade swore vengeance against Oliver as well upon learning that he chose to save Sara Lance over Shado, a woman he supposedly loved. During a climactic battle aboard the Amazo, Oliver presumably killed Slade after stabbing an arrow into his right eye. However, Slade survived and returned five years later as the mercenary "Deathstroke", with the intention of taking away everything and everyone Oliver held dear as vengeance for the events that transpired on Lian Yu. Working with Sebastian Blood and Isabel Rochev, Slade gathered an army and launched an all-out assault on Starling City, murdering Moira Queen in his blood lust. His plan ultimately failed, as he was cured of the Mirakuru and subsequently imprisoned in an A.R.G.U.S. facility back on Lian Yu.

However, in May 2017, Oliver visits Slade again on Lian Yu. Having long-since recovered from the mental-impairment of Mirakuru, he agreed to Oliver's requests to help in freeing his friends and combating Adrian Chase, all in the hopes of redemption and to find his lost son Joe.

In one potential timeline, Slade fathered a son named Grant Wilson, who would take up his father's mantle as Deathstroke.

Biography

Early life

Slade was an Australian Special Intelligence Service's operative who went on numerous missions with partner Billy Wintergreen.[2] Slade also married a woman named Adeline, with whom he had a son, Joe, and picked Billy to be his son's godfather.[3]

Plane crash on Lian Yu

In 2006, Slade and Billy Wintergreen were tasked with rescuing Yao Fei Gulong, a former Chinese military commander purposely shipwrecked on Lian Yu by his government to conceal a massacre that had been perpetrated eight years earlier. However, their plane was shot out of the sky whilst en route to the island's air strip, and the two were captured by men working for Edward Fyers, a mercenary who had been hired to take Yao Fei hostage for unknown reasons. Fyers asked both Slade and Billy to join his cause, but while Slade refused, his friend accepted Fyers' offer. Slade was held prisoner in Fyers' camp for almost a year until Yao Fei managed to free him. The two took refuge in the wreck of Slade's plane. They planned to escape the island by stealing a supply plane that made regular stops on the island's air strip, but before they could do so, the two were separated.

Facing Edward Fyers and meeting Oliver Queen

Oliver meets Slade

Slade meets Oliver.

Six months later, Slade caught a young Oliver Queen, who had been shipwrecked on Lian Yu, searching through his hideout. Oliver explained that Yao Fei had sent him, but viewing him as a liability, Slade attacked Oliver and knocked him unconscious. He bound Oliver to a chair by his wrists. When Oliver woke up, Slade explained to him that he had to kill him, just before Oliver freed himself by dislocating his thumb. Oliver went on to punch Slade in the face, convincing Slade that he was worth keeping alive. Slade told him he needed another person to implement the plan he and Yao Fei had made to steal the supply plane. While choosing a weapon, Oliver found Slade's mask that was identical to that of Wintergreen, who had tortured Oliver at Fyers' camp when he first arrived on the island. Not realizing it was another mask, Oliver accused Slade of deceiving him, but Slade explained both he and his ex-partner wore the mask to protect their identities, as well as their allegiance to ASIS and their mission.[2]

Oliver and Slade blackmail Fyers

Slade and Oliver attempt to take the airstrip.

Slade attempted to train Oliver to fight, to not much success, until he gave the younger man the option to escape or die. They had only ten days to train before the plane arrived on the island. On the tenth day, they started their journey towards Fyers' camp. On the way, Oliver stepped on a land mine, presumably left behind from World War II. When some of Fyers' men approached their position, Slade killed them and used one of their bodies to free Oliver. That night, Slade revealed to Oliver that Wintergreen had betrayed him immediately after their capture, and that he was the godfather of Slade's son. Once they reached Fyers' camp, Slade proceeded to take out the soldiers with his sniper rifle, as Oliver reached the communications tower, with his only duty being to kill the man there. Oliver failed in his task, but Slade managed to get there in time to kill the man right before he shot Oliver. Slade told Oliver he would call in an airstrike to blow up the island after they left. Concerned about Yao Fei, Oliver left to bring the other man back with him. Slade stayed behind and told him he had three hours or he would be left behind. Despite what he said, Slade went back for Oliver and saved him from Wintergreen. He managed to kill Wintergreen, but was shot in the arm by Fyers. Slade acknowledged Oliver had proved himself to be a fighter.[3]

Slade's wound was infected, forcing Oliver to head out to find herbs which could fight the infection. Oliver came back with the herbs and claimed not to have encountered any problems.[4] When Oliver attempted to fix the damaged radio they had obtained from the communications tower, Slade joked "pigs would fly" before he succeeded. Ironically, Oliver managed to repair the radio, shocking Slade. However, they discovered the radio could only receive, but not transmit, so they could not use it to call for rescue. As Slade listened to the soldiers' frequency, he overheard Fyers talking about something called Scylla to an unknown man. Oliver explained Scylla was a monster in the Odyssey by Homer. The two men left to discover what Scylla was and found it was a missile launcher.[5]

To get closer to the missile launcher, Slade pretended to be a prisoner taken by Oliver. The ploy worked, and Slade managed to kill all the guards around the missile launcher. Just as he was about to destroy it, Oliver stopped him and took out the circuit board instead, effectively stopping the missile launcher from working. Slade was excited to have a leverage over Fyers. Oliver contacted Fyers and arranged to trade the circuit board back to him in return for a way off the island.[6] At the meeting, Fyers questioned if he could trust them to be truthful. Slade answered he himself would not, but Oliver had a thing for principles. Fyers took advantage of that and brought out Shado, Yao Fei Gulong's daughter. When Fyers threatened to kill Shado, Slade attacked him, providing enough distraction so he and Oliver, along with Yao Fei and Shado, could escape. On the way, Yao Fei was shot, and he told the others to leave him behind. When they returned to their hideout, they discovered that the circuit board was missing. Slade was angry at Oliver for being played, until Shado pointed out that Fyers could not risk them leaving the island with their knowledge anyway.[7]

Slade started sparring with Shado, with the two proving to be equally matched. When Shado asked how well a fighter Oliver was, Slade answered he had tried to train Oliver with limited success. Shado decided to train Oliver himself, and Slade left them to it. When he returned later, Slade found Oliver slapping a bowl of water and found out he had been doing it all day. Shado claimed the exercise built strength, and was proven correct when Oliver managed to draw the bow in their possession, impressing Slade with the technique. Later, Slade discussed how to rescue Yao Fei with Shado and came to the conclusion they would need someone else to watch their back. Slade refused Shado's proposal to have Oliver do it with the bow, saying he was not ready. Shado took Oliver away to train, and told Slade if he was not ready by the end of the day, they would try a new plan.[8] When they returned, Slade found out Oliver had failed at hunting down an animal. Before they could formulate a new plan, however, Yao Fei arrived with Fyers' soldiers to surround them. Angry at Yao Fei's betrayal, Slade attacked Yao Fei but was knocked down by one of the soldiers.[9]

Fyers took the three back to his camp. When he wanted to make a point to Yao Fei, he shot Slade in the leg. Slade witnessed Yao Fei's death when Fyers had no more use for him and shot him in the head.[10] Slade, Oliver and Shado managed to break their bonds and attacked Fyers and his men. Slade survived the blast from the missile launcher and joked Oliver could not save the day without making a mess. Fyers arrived with Shado, revealing he had survived the blast, and angry at Oliver for ruining his two-year operation. Oliver killed Fyers using Yao Fei's bow, impressing Slade that he could kill.[11]

Shado's death and betraying Oliver

Oliver improves his fighting skills with Slade

Oliver and Slade train.

5 months later, Slade continued to mentor Oliver. While sparring, Oliver got distracted and he hit him, saying, "You're not the first one to learn the hard way women are a distraction." A few minutes later, a proximity detector device they had salvaged from the wreckage of Fyers' camp went off, and they went looking for the people the device had detected, but Shado was quickly captured, so Oliver and Slade chased after her. Later, Slade and Oliver caught up with Shado and the people who captured her. Slade tried to stop Oliver from doing anything rash, but the leader hit Shado, and Oliver became enraged and attacked the leader while Slade attacked the others. Slade and Shado were shocked when Oliver was unable to control himself and kill the leader. Moments later, Slade picked up a radio that went off, and the three were left wondering how many more men are on the island and where they came from.[12]

Slade talks to Shado and, knowing what he's going through, asks her to comfort Oliver. He finds a map, similar to the one provided to him by ASIS. Later, Slade sees Oliver and Shado by the river, becoming closer. He reminds Oliver that women can be a distraction, and that that can get him killed, as they leave the riverside. They go to the location in the picture, and Oliver soon after directs him and Shado to a cave. There he discovers a blade, in which he says is 60 years-old, and they also discover the remains of World War II Japanese soldiers.[13] Slade has Oliver tag along with him to scout for the new threat to the island, telling him that Shado can take care of herself as they leave. As they are going up to higher ground, Slade once again reminds Oliver that woman can be a distraction, while in conversation Slade almost falls off the cliff side if not for Oliver catching him in time. Slade and Oliver make it to the top of the cliff and spy the ship firing at a fixed location where they work out is where the plane is which causes Oliver to run with Slade giving chase. Slade is chasing Oliver while the area is still under fire. Slade is last seen being hit by an explosion, with his hands and the right side of his face on fire, yelling in pain.[14]

Slade Wilson with a half-covered face

A badly wounded Slade holds Ivo at gun point for Oliver.

Slade survived the attack and is seeking refuge on the island. The explosion has left severe burns on one side of his face, however, as Shado tends to his wounds. Despite his warning to leave him for safety, Shado declares that she is here to stay, and would never leave anyone she cared for alone.[15] Slade is still weak and extreme pain, with a herbal ointment covering to the right side of his face. When Anthony Ivo's soldiers attack the plane, Slade and Shado hide. Although quite bruised, they later managed to rescue Oliver and Sara Lance from Ivo. Oliver says that if they find the serum, it could possibly heal Slade's wounds.[16] The group find the submarine and the Mirkauru on-board but can't find a sedative to give Slade first. Oliver gives Slade a choice as the injection without a sedative could kill him but Slade agrees but before Oliver gives it to him he confesses his romantic feelings for Shado. Oliver then injects the Mirakuru into him. The injection causes blood to come out of his eyes, and then he collapses into unconsciousness though the others believe him to be dead.[17] When Ivo catches up with the group he checks Slade's pulse and appears to be dead. But Slade awakens a few minutes after his injection with Mirakuru, calling Shado's name. He runs to the site where Ivo has killed Shado, and thanks to his Mirakuru-enhanced physical capabilities, he easily slaughters Ivo's men. He then picks up Shado's body and vows that the person responsible for her death will suffer.[18]

Slade, Oliver and Sara bury Shado

Slade, Oliver and Sara bury Shado next to Yao-Fei and Robert.

Slade, Oliver and Sara bury Shado next to Yao Fei and Robert Queen's gravesites where Slade hands Oliver Shado's hood acknowledging that Oliver was the one she cared for. Later Slade wants to get geared up to kill Ivo and his men but Sara tells him that he can't handle it by himself but this enrages Slade as Sara was working for Ivo but when Oliver tries to break them up, Slade starts chocking Oliver to death until Sara uses a tree branch to stop him before he Sara tells him that the Mirakuru is affecting his mind. Later without Sara or Oliver, Slade takes the Mirakuru serums and heads after Ivo himself.[19] Slade uses Fyers’ missile launcher and intended to open fire on the freighter until he was confronted by Oliver and Sara who threatened to kill Oliver but he managed to make him see reason using Shado and Joe. He then sat down and questioned what was happening to him, Oliver promised him that he wasn't going to give up on his friend and soon proclaimed they were going to take the freighter from Ivo.[20] Slade, Oliver and Sara are observing Ivo's ship from a cliphead until they hear a plane flying overhead. The three try to get it's attention but it is shot down, the pilot dying. Slade and Oliver rush back to the plane to get medical supplies but arrive too late. They do however find a parachute in the pilot's plane.[21]

Slade observes Oliver’s training and is impressed. Slade agrees that they should burn the last remaining Mirakuru prior to their attack on the freighter. Before attacking the ship Slade notes the first time they attempted to escape was as strangers but now was as brothers. As they reach the freighter, Slade tells Oliver and Sara not to kill Ivo as he wants Ivo for himself. Slade learns the truth about Shado after listening in to Oliver and Ivo's conversation. An enraged Slade attacks Oliver violently but Oliver slips away from him as explosions occur on the freighter. As Oliver attempts to escape the freighter, Slade grabs Oliver by the leg and imprisons him. When the Butcher, the ship's captain orders him to enter the cell with Oliver, he refuses. He crushes the skull of the Butcher who attempts to shoot him and declares himself the new captain. Later, he would ask Ivo to show him how he killed Shado and then lacerates Ivo's hand. Slade then promises to Oliver he will make him suffer in the same way he suffered before killing him.[22]

Slade continues to torture Oliver on the Amazo while having his crew repair the ship, but are unable to repair the damage to the engines. Slade contacts Sara on the island and demands that Hendrick Von Arnim, an engineer who escaped in the siege, be handed over or Oliver dies, electrocuting him in the process. Slade also brands Oliver with the same tattoo Shado had to remind him of her death until his death, eventually Sara also agreed to hand Hendrick over.[23] Slade returns Oliver and Ivo both to the island in exchange for Hendrick, who has been secretly rigged with explosives, but as his men take him outside Slade senses the explosives due to Mirakuru and removes and disables them. He then wants to kill Sara and Oliver but has a hallucination about Shado who tells him to leave them on the island forever. As Slade walks outside he tells Oliver that once the ship is ready, he is going after his family.[24] Later Slade had his men take Sara on the island[25] and locked her in a cell. When Oliver sneaks aboard to free her and find the Mirakuru cure Ivo mentioned, Slade was waiting with the cure in his hands and had Oliver and Sara captured.[26]

Slade, wearing his original balaclava, holds Sara at gunpoint.

Slade forces Oliver and Sara to watch as he injects unwilling prisoners with the remaining Mirakuru, having become obsessed with making others like him, but Oliver and Sara pleaded with him to release them and to come to his senses, but his hallucinations of Shado instead convince him to kill them. He puts his mask on and prepares to kill both, but Anatoly fires a torpedo from the submarine, which causes the ship to split in half and Oliver uses the chance to destroy the Mirakuru in a resulting fire. But Slade engages Oliver and throws Sara into the split which apparently causes her to drown. Oliver out of anger attempts to fight back but is completely outmatched. Before he can kill Oliver however some rubble falls from the ceiling and traps Slade. Oliver has the choice to either kill Slade or cure him. However, after more taunts from Slade, Oliver chooses to kill Slade by stabbing him in the eye with his arrow. The ship sinks and Oliver is saved by A.R.G.U.S. from the remains of the ship.[27]

After Lian Yu

Deathstroke's A.R.G.U.S. profile

Deathstroke's profile on the A.R.G.U.S. database.

While it was presumed that he was dead, Slade in fact survived Oliver's attack. He swam back to Lian Yu, planted his mask on the shore with an arrow through his eye,[citation needed] and then tried to swim to the nearest coast line, but was cut down to the bones by the rocks and debris in the ocean. The Mirakuru regenerated everything but his eye.[24] After the island, Slade attempted to forget everything that happened, reuniting with his son Joe and wife Adeline, but the events of the island would still haunt him.[24] When Slade returned to Perth, he found the Mirakuru was apparently no longer in his system. He continued working for A.S.I.S. for several months, working at a desk and trying to track down Oliver. During this time, Slade trained with Digger Harkness several times, trying to regain his strength. During Slade and Harkness' final fight, Slade's Mirakuru-enhanced strength returned, and he defeated Harkness.

Slade's superiors discovered that he had been using A.S.I.S. resources to track down Oliver and attempted to confront him at his home. Slade was distracted during the confrontation by seeing a news report on television that Oliver had returned to Starling City alive. He fought the A.S.I.S. agents, killing them all. Adeline was also killed in the crossfire, and his son Joe went missing. Slade renewed his vow to kill Oliver, and decided to find allies to help him in his mission.

Slade would eventually become a mercenary that A.R.G.U.S. would codename "Deathstroke", but A.R.G.U.S. remained unaware of his true identity.[28]

War with Oliver Queen

When Oliver became the Starling City vigilante called The Hood and exiled himself back to the island after failing to stop Malcolm Merlyn's undertaking,[12] Slade planned a mission of vengeance to destroy Oliver and Starling City with an army of Mirakuru soldiers, to cause enough damage to force Amanda Waller to airstrike Starling City and leave nothing left. He became associated with Isabel Rochev who he planted in Queen Consolidated to take over in order to draw Oliver back, but also to seize control of Oliver's company so that he would lose everything from his funds, house,[29] his Arrowcave and even his former club.[25] He also trained Isabel to fight and gave her a uniform similar to his under the name "Ravager".

Slade also became associated with Alderman Sebastian Blood and funded his mayoral campaign. He promised him control of the city using an army of Mirakuru soldiers[24] to reduce the city to a state of desperation, and in that desperation, the people would turn to Blood for guidance. In reality, Slade simply needed Blood for other reasons, like testing the Mirakuru and preventing the national guard from intervention.[25] To create his serum, Slade had Sebastian use his influence to put together a cult, the Church of Blood, to find people to test a new strain of the serum on and would manipulate them using a skull mask masquerading as “Brother Blood”.[30]

Slade visited Moira in person who, when Oliver returns home, introduces Slade to him, unaware of Oliver and Slade's history together, which leaves Oliver in a state of shock.[21] Slade continued to "socialize" with Moira and Oliver, but passive-aggressively taunts Oliver about their past and is offered a tour of the Queen Mansion by Moira Queen and Thea. He secretly plants bugs with cameras all over the house. During the tour, Oliver secretly calls Felicity to inform Sara that Slade is alive, and she and Roy Harper come to the house to discreetly intervene. When Roy introduces himself, Slade notes his "particularly firm handshake" and realizes Roy is injected with the Mirakuru before being stunned to see Sara alive, and Slade knows it's time to leave. Oliver offers to walk him to his car, aware Diggle is planning on killing Slade, but he is secretly taken down by Ravager and Oliver works out that he is the true mastermind of Brother Blood's schemes.

Some time later, Slade was incarcerated in a A.R.G.U.S. supermax on Lian Yu. Oliver visited him and talks to him. Slade however argued that Oliver isn't a hero and will always be a murder since he created him, which Oliver acknowledges and that if it weren't for Slade he wouldn't be alive today. However it's also because of Slade, despite all he'd done, his plot is what made him not a killer but a hero and thanks him. As Oliver is walking out Slade angrily scolds him for believing he won't escape and yells to him that he keeps his promises as Oliver leaves, continuing to yell at him as he leaves.

However, Oliver managed to convince her not to kill Slade, but she still shot him in the shoulder. Returning to the Supermax, Slade noted that Thea was not the killer Oliver was. As Oliver was leaving Slade taunted him about the people he had lost and how losing any more would leave nothing of Oliver Queen.[35]

Not long after that, the effect from the Mirakuru wore off, and because of that, Slade finally became sane again. For the next 2 years, Slade thought about his actions. He finally realized that Shado's death wasn't Oliver's fault, and forgave him. He also started to regret his actions, and took a full responsibility for them. [36]

As Oliver arrived, Slade expressed his gratification for the former's return.[37] Slade expressed that the mental side effects of the Mirakuru were completely gone and he was back in his right mind, expressing guilt over his vendetta against Oliver. Oliver offered Slade information on his son Joe's whereabouts in exchange for help freeing Oliver's friends and son. Slade donned his Deathstroke armor and set out with his Oliver and Harkness, who Oliver also freed, to find and rescue Oliver's friends. When they found some of them trapped in Edward Fyers' old cages, the trio was ambushed by Talia al Ghul and Evelyn Sharp, at which point Harkness revealed they had recruited him earlier and he betrayed Oliver and Slade. Harkness implored to his old friend to make the sensible choice and join him on the winning side, and Slade seemingly accepted, telling Evelyn to put her gun to Oliver's head, but as Harkness expressed gratitude at Slade being smart in his decision, Slade berated Digger for simply assuming that he was on the winning side and suddenly assaulted his former friend. Oliver quickly disarmed Sharp and Talia was forced to escape with Harkness as Malcolm Merlyn and Nyssa al Ghul arrived on Oliver's side. As Slade forced Sharp into a cage, he coldly advised Sharp to pick better friends since they left her behind, but she remained defiant, stating it might as well be part of the plan. After Malcolm led Oliver's friends to the plane to escape, Nyssa, Oliver and Slade went to track down Talia's trail to the hideout. As Nyssa went ahead to recover the lost trail, an amused Slade mentions how Oliver married Ra's al Ghul's daughter Nyssa instead of Felicity, and helped Oliver to come to terms with his father's suicide. Slade told Oliver he needed to forgive himself and not blame himself for his father's death, advice that Oliver later accepts to make peace with his past sins.

Upon reaching the enemy hideout, Slade helped Oliver reunite with his friends by feigning betrayal yet again, and then assisted Nyssa al Ghul against her sister's acolytes upon her triumph over Talia. Slade then fought alongside Team Arrow and Nyssa in defeating the acolytes with Adrian Chase, and witnessed Oliver besting Chase, but was visibly shaken when Chase claimed to have murdered Oliver's son William. He took his mask off and stepped towards Oliver with sympathy, only for Oliver to express disbelief at the claim. Oliver had Slade accompany his friends in getting off the island. When Team Arrow learned the plane they wanted to use was sabotaged, Slade said that they would not leave without Oliver and William, even though Oliver asked him over comms to escort the others to an A.R.G.U.S. supply ship. When Adrian Chase killed himself to detonate the explosives covering the island, Slade and Team Arrow were presumably killed in the island's destruction.[38]

Future

In a potential future, Slade had another son named Grant Wilson. Grant succeeded his father as Deathstroke and launched an assault on Star City known as the Uprising in 2031, during which he killed the majority of Team Arrow and left Oliver physically disabled. However, in this future Oliver stated Slade tried to destroy him and made no mention of Slade's redemption during the war with Prometheus, indicating that the timeline has changed, most likely due to Flashpoint.[39]

Personality

Oliver and Slade blackmail Fyers

Slade and Oliver attempt to take the airstrip.

In the flashbacks, unlike the DC comics character counterpart he was based on, Slade is less cold and distant, but retains his appearance of an anti-hero. Slade is a man of honor and good morals, who puts up a tough act, but underneath is a caring individual, as shown by his rescue of Oliver from Edward Fyers and Billy Wintergreen, even after stating that he'd leave the island if Oliver didn't return in time. Slade does not take well to traitors, which he shows by killing Billy Wintergreen, his friend and partner for many years until he betrayed Slade in exchange for his own life. Slade is very open about his opinions of people, frequently calling Oliver an idiot, and doesn't hide that he likes Shado, which she often smiles at. Slade only trusts and cares for people who have proven themselves trustworthy to him, as he trusts Oliver and Shado, but was less trusting of Sara Lance as they had barely known each other.

Slade was also a realist but also open minded. Upon realizing Oliver was hopeless in helping him take down Edward Fyers, he decided to perform a coup de grace on Oliver to spare him any suffering from facing Edward, but also to prevent his location from being given up. However, upon realizing being on the brink of death began to awaken the warrior inside Oliver, Slade changed his mind about killing Oliver and decided to train him. Slade's isolation on Lian Yu and Wintergreen's betrayal has turned him into a little bit of a cynic, admitting to Oliver that he was disgusted how Billy could have betrayed him despite being the godfather of his son even believing that "everyone in this world is out for themselves". Slade's cynicism was also shown in his sense of humor, normally being tough, sarcastic and a little bit deadpan towards Oliver and his incompetence, however, he was also capable of being impressed as a mentor would be. He soon began seeing Oliver more of a brother than a friend.

Slade in his old mask pointing a gun

Slade, wearing his original balaclava, holds Sara at gunpoint.

Slade's personality takes a turn for the worse after his injection with the Mirakuru, which combined with his grief over the loss of Shado makes him impulsive, reckless, aggressive, violent, and bent on revenge against Ivo. Once he discovers Oliver's shared role in Shado's death he becomes completely hell bent on revenge against him which would stay for years after, tarnishing the brotherly bond they once had and making them bitter enemies.

Deathstroke taking the prisoners

Slade as the mercenary known as Deathstroke.

In the present day Slade's anger and hatred has increased more to the point of full vendetta against Oliver upon learning of his survival on the island. Slade is intelligent, calculating, and patient; he waited 5 years to get/plan his revenge against Oliver. He is also overconfident and boastful of his Mirakuru powers and has no fear of Oliver because of them. These traits are well deserved as bullets do no harm to him and even getting cut to the bone doesn't affect him as it all heals back, though explosives and poisons can still harm him but only for a brief time.

Slade is rarely caught off guard, he also has little tolerance for disobedience, failure and disloyalty, as multiple times he threatened to kill Sebastian Blood for his failures, eventually having him killed for betraying him. Due to the Mirakuru, Slade's sense of honor has become twisted, and when it comes to Oliver, he is cruel, sadistic and ruthless. He displays little emotion when killing innocent people. He also has developed a complete disregard for human life and watched in amusement as his army tore Starling City apart, his only regret being that Shado couldn't be there. He also holds little regard for his own allies as he cared little for his own men being cured, however Slade seems to be close to Isabel as he seemed desperate to have her revived by the Mirakuru. However Slade was still willing to abandon her to Oliver during the attack and it's unknown if he is aware of Isabel's death at Nyssa's hands or how he feels about it. Slade also suffers from hallucinations of Shado which have lasted from the past to present.

Even when cured from the Mirakuru the physiological effects have still remained as Slade still vows to kill Oliver even when confined and defeated. Even a whole year later this vendetta still stayed when Oliver and Thea were trapped on the island with him. Though he had become less hostile and wasn't even phased by being imprisoned again and even gave advise to keep Thea away from Malcolm, but reminds him that he will break if he loses more people, hinting that he has regained some respect for his former protegé and former friend.

When Thea had him at gunpoint, Slade tried to goad Thea into killing him knowing that this would cause permanent emotional damage that would send her in the same darkness he and Oliver had been through.

Slade Wilson

Slade with his sanity restored.

Three years after his imprisonment on Lian Yu, when Slade sees Oliver return to his cell, he express gratification and respect Oliver again, as he no longer hates/blames the latter for Shado's death; due to the fact that the psychiatric and psychological effects of the Mirakuru had worn off long ago (prior to May 2017). Slade has reverted back to his original personality, as he truly feels guilt and remorse for his actions while under the drugs influence. He was willing to help Oliver save his son and friends, remaining loyal to his old friend despite multiple chances to betray him. Slade even helps save Oliver's friends and family, including Felicity Smoak, Thea Queen, Curtis Holt and even Nyssa al Ghul. He was visibly shaken when Adrian Chase claimed to have killed Oliver's son William Clayton, likely due to the fact that he is a father himself.

Deathstroke

Slade as the anti-hero Deathstroke.

Slade even elects to not abandon his old friend or his son despite Oliver wanting Slade to get off the island with the rest of Team Arrow, showing Slade has truly regained his sanity, morals, honor and loyalty to Oliver. As Slade and Oliver once thought of each other as brothers (prior to the former being injection with the Mirakuru), Slade once again respects Oliver and helps the latter come to terms with his father's suicide. He tells Oliver not to continue to blame himself, and to forgive himself to finally make peace with his past. Oliver later follows Slade advice and frees himself of the guilt of his past sins.

Powers and abilities

Powers

Former powers

  • Enhanced physical condition: Slade received the Mirakuru serum, which altered his physiology. The injection initially made ​​him either faint or temporarily die as Oliver felt no pulse before he woke, with extreme pain and bloody tears as side effects. After his awakening, his whole body boosted to limits that far exceed those of a normal human. Among their physical capacity were increased stamina, strength, durability, agility, senses, reflexes, and an accelerated healing factor. The effects of the serum were lost when Oliver cured him.
    • Accelerated healing factor: The Mirakuru serum injection has greatly enhanced Slade's ability to heal, allowing him to rapidly recover from even the most crippling, debilitating and grievous of injuries, so long as they would not immediately be fatal. By the time he awoke after the injection, the injuries on the right side of his face and the after effects of his injuries earlier were completely healed. He was shown to be shot through the chest, and it does not affect his abilities. According to him, Slade was carried under the water after somehow being defeated by Oliver and was badly torn apart by the rocks, but his body, was eventually healed.[24] It was revealed that Slade was not defeated by Oliver; the reason why he ended up under-water was because he became immobilized by falling debris from the Amazo, which was sinking.
    • Enhanced agility: Thanks to the Mirakuru serum, Slade is more agile than any normal human could be.
    • Enhanced durability: The Mirakuru serum, increased the resistance of the muscle and bone structure of Slade, causing them to become more durable than a normal human's, as he was barely fazed while being hit with large tree branches, which was done by both one of Ivo's men and by Sara. In addition, when Slade was punched by Roy, also injected with the Mirakuru, he was barely fazed.[24]
    • Enhanced senses: Slade was able to smell the TNT of a Japanese landmine strapped to Hendrick Von Arnim. It can also be assumed that he also can see and hear, far better than any normal human could.
    • Enhanced speed: Slade can run at speeds out-performing any Olympic athlete. He was able to run from the submarine to another side of the island, where Oliver and Shado where held, in minutes while it took at least a few hours for everyone else to traverse the island on foot. Slade also managed to kill three of Sebastian Blood's men behind him, dive in front of Blood and disappear again in a matter of seconds. When Oliver was out on patrol looking for Slade, Slade was already behind him on one of the rooftops, when Oliver turned around, he was already gone. Slade, possibly, is so fast he will disappear in a second when someone looks away or is not looking at him.
    • Enhanced stamina: Thanks to the Mirakuru serum, less fatigue toxins were produced, allowing Slade to exert himself at peak capacity greater than any human could. His stamina was so seemingly inexhaustible that Slade was able to swim non-stop across an entire ocean to escape from Lian Yu without drowning.
    • Enhanced strength: Thanks to the Mirakuru serum, Slade's muscular system allows for incredible strength. He was capable of effortlessly launching Ivo's men several meters away, breaking an assault rifle in half with his bare hands, and piercing a man's chest with only his fist by punching him.

Abilities

  • Eidetic memory: Slade is shown to have a perfect memory. He remembered the exact details of Shado's dragon tattoo, as Slade had one of the Amazo's crew branded it on Oliver's back, to forever remind Oliver that he was partly responsible for Shado's death.
  • High-level intellect/Master tactician/Leader: Slade is very intelligent and a flawless tactician, he is able to create plans for combat, infiltration and destruction. He is extremely efficient, even at great disadvantage, or with few resources. Slade with the help of Oliver quickly formulated a plan to take over an airfield crowded with troops, and later managed to destroy much of Edward Fyers' compound alone, using only improvised explosives and distraction. Later Slade was seen doing various mathematical calculations, to program a missile launcher directly to the ship Ivo. He proved an expert in fighting techniques, developing specific plans to attack his targets, using the environment to his advantage and distractions. He was able to calculate the flight with a parachute to land on a freighter. After the island getaway, Slade went on to a personal vendetta against Oliver, he devised an extremely complex plan that could keep his enemies, like The Arrow overwhelmed, as well as infiltrate within the government of Star City, taking Queen Consolidated away from Oliver, and by the end create an army of Super Humans that can generate chaos and destruction throughout the city. Slade is also a capable leader, he was able to lead an organization known as the Church of Blood with Sebastian Blood, and was able to do it in secret.
  • Indomitable will/High pain tolerance: Slade has a high tolerance for pain. Oliver had to pull a bullet out of Slade's arm without any form of anesthetic, albeit he had to tie him up (on Slade's suggestion) because he might kill Oliver otherwise. He was also able to take down several of Edward Fyers' henchmen with an injured leg.
  • Master hand-to-hand combatant/Martial artist: Slade is shown to have very advanced unarmed and close-range fighting skills, and likewise able to effectively mentors Oliver in his ways. He was able to spar with Shado to stalemate her in combat, although it can be implied that Slade held back a little. His fighting style mostly incorporates Escrima with Muay Thai while supplemented with Karate, Silat and Boxing. After augmented by the Mirakuru, Slade's combat skills have increased to the point where he was able to easily beat Oliver, John Diggle and Sara Lance at the same time. After he was cured from his Mirakuru powers, Slade was not able to defeat Oliver, despite the fact that he is more experienced in combat than Oliver, due to Slade having problems remaining conscious due to the Mirakuru cure which knocked out his soldiers immediately. A year after being imprisoned on Lian Yu, Slade was able to knock out Oliver and Thea in mere seconds. In a second encounter he fought Thea and Oliver at the same time, before Thea pulled a gun on him and shot him in the arm, implying that he has been retraining himself (off-screen), it is very likely that his combat skills will eventually return to the way they used to be, before he became reliant on his Mirakuru powers. When Oliver recruits Slade against Adrian Chase, and his allies, Slade easily slaughtered Talia al Ghul's acolytes whose training is nearly identical to the League of Assassins in mere seconds, showing that Slade is still one of the most deadliest fighters in the multiverse.
  • Master knife-thrower: Slade is a master knife thrower, he was able to kill a guard at S.T.A.R. Labs' Starling City branch with a throwing knife.
  • Master marksman/Firearms: Slade is shown to be an excellent marksman as he took out many soldiers with his sniper rifle, and was able to take out several soldiers with only two handguns.
  • Master stick fighter: Slade is a master stick fighter, as he was seen sparring with Oliver in stick fighting, teaching him everything he knows about stick fighting.
  • Master swordsman: Slade is a master swordsman, cutting down multiple armed mercenaries in mere seconds. He has explicitly stated his weapon of choice are swords. He killed his former partner in a sword-fight, who was also a master swordsman. In the present day, due to his Mirakuru powers, Slade's swordsman skills have increased to the point when he was able to kill three of Sebastian's bodyguards in a matter of seconds. Beside his prowess at close range he was also shown to be able to kill a guard by drawing his sword and throw it in one single motion.
  • Master of deception: Slade is a very good liar, able to feign betraying Oliver twice by joining Adrian Chase in order to get the latter and his team's guard down.
  • Peak of human physical condition: Slade is in top physical condition. His reflexes allowed him to catch an arrow shot at him by Oliver.
  • Stealth: Slade was able to steal a file from the archives without being seen on the security cameras. Slade was able to stalk Oliver without getting noticed. Slade was able to enter Verdant, and then enter the Arrowcave, without being seen, noticed, or making any alarms go off. On Lian Yu he was able to sneak up on Thea and Oliver multiple times.

Weaknesses

Former weaknesses

  • Deathstroke suit: In present day, Slade wears a protective suit as his villain alter-ego, Deathstroke, to hide his identity from his victims.

The costume also has orange details on all of the joints. There are various equipment pockets on the costume, and there are three smoke grenades and ammunition strapped on to the chest.
