The Mirakuru cure is a serum designed to cure individuals of their Mirakuru powers, as well as their deformed bodies and the insanity caused by the Mirakuru serum.


After injection, individuals are cured of their Mirakuru powers as well as their deformed bodies and the insanity caused by the serum. After they are cured, the individuals immediately lose consciousness; however, Slade Wilson remains conscious longer than his soldiers, possibly due to having had his body become accustomed to the use of Mirakuru. Slade displays no effects of the serum months later, including a lack of hallucinations and most of the insanity afterwards, though he is still antagonistic towards Oliver. It was later revealed that the psychiatric and psychological effects of the Mirakuru takes longer to wear off than the physical effects, as Slade returned to his former-self 3 years after being cured and described what he did under the Mirakuru's effects as a "bad dream".


Anthony Ivo had spent his whole life studying the Mirakuru. It was because of this that he was able to figure out how to make a cure for it. However, this version of the Mirakuru cure was not made directly from the Mirakuru serum; he made it from the prisoners that he had tortured and experimented on the Amazo ship. After Sara Lance is captured by Slade Wilson, Oliver Queen goes to rescue her. He asks Anatoly Knyazev to sink the Amazo if he does not return in one hour. After Oliver rescues Sara from the cell she was held in, she leads him to where the cure is located; however, Slade had already discovered the cure and has it in his possession. Oliver and Sara are captured by Slade once again.

Oliver and Sara fail to return in 1 hour, so Anatoly launches a torpedo from a 70-year-old Japanese submarine that he managed to get working. As the Amazo sinks, Oliver and Slade battle against each other; however, Slade becomes immobilized by falling debris. Oliver has the chance to use the Mirakuru cure on Slade but chooses to kill him. However, due to Slade's Mirakuru healing powers, he survives having an arrow drive through his eye by Oliver, who would come to regret this mistake 5 years later.

After Slade steals a biotransfuser from S.T.A.R. Labs in order to transfer his blood to the prisoners he rescued from Iron Heights Prison and create his own army, Oliver realizes that Slade will be weak enough for him to kill. Oliver asks Felicity Smoak how they can locate the machine Slade stole, to which she explains that a machine like that would drain a huge amount of power from the city's grid when activated and that she knows where it is. Oliver gets a call from Felicity, who tells him that Slade has turned the biotransfuser on and she knows where he is now; Oliver goes to Slade's hideout when he gets there but finds that it is Roy Harper who is plugged into the machine, not Slade.[1]

Slade reveals that he and Isabel Rochev captured Roy when he was in Blüdhaven. Oliver battles Slade and Isabel; he defeats Isabel easily, but he is no match for Slade due to his Mirakuru powers. Oliver is forced to use the two small explosives from his customized Oneida Kestrel lever-limb compound bow to knock Slade out. Oliver then rescues Roy, retrieves a sample of the Mirakuru, and returns to his secret headquarters.

Oliver reveals to his team that there is a cure for the Mirakuru and that Anthony managed to create it. He also reveals why he never mentioned the cure -five years ago when he had a chance to use it on Slade, he instead tried to kill him; Oliver feels that everything that is happening is because of that choice. Felicity takes the Mirakuru sample to Cisco Ramon and Caitlin Snow and asks them to do her a favor and synthesize a cure, as well as to keep it a secret.

Felicity gets a call from Cisco saying that the Mirakuru cure is possibly finished.[2]

Felicity tells Oliver and her team that the Mirakuru cure is ready and there's a courier en route. The courier is attacked by one of Slade's soldiers. Unbeknownst to Team Arrow, Slade hacked into their phones and knows about the Mirakuru cure. He sends one of his men to acquire it before Oliver and his team can; Sebastian Blood steals the Mirakuru cure and gives it to Oliver, who hesitates to use the cure on Roy because he doesn't know whether it will cure or kill him. However, after he learns that Amanda Waller is going to bomb the city at dawn to avoid Slade's men from attacking the rest of the country, Oliver is forced to use the cure on Roy.[3]

The Mirakuru cure doesn't seem to work. After Roy regained consciousness, Oliver and his team are attacked by one of Slade's soldiers. Roy punches one of the soldiers but the action causes him a lot of pain, revealing that the Mirakuru cure does indeed work. Oliver, Sara, Nyssa al Ghul and the League of Assassins go to Queen Consolidated, where they use syringe arrows to cure every enhanced Mirakuru soldier in Queen Consolidated; however they are unable to cure Slade due to the fact that his Deathstroke Costume is not only bulletproof but arrow-proof as well. Oliver, Sara, Roy, Nyssa and the League of Assassins battle and cure the rest of Slade's enhanced Mirakuru soldiers. Slade takes Felicity hostage, unaware that it is a trap setup by Oliver. Oliver distracts Slade long enough for Felicity to inject the Mirakuru cure into his neck, which cures Slade of his Mirakuru powers. The team also cures the last remaining member of Slade's army.[4]

  • It is not known whether Anthony Ivo's synthetic version of the serum permanently cures individuals of their Mirakuru induced powers or whether it merely suppresses them; this modified formula was derived from experimentation on test subjects and was, by Anthony's own admission, not an exact replica of the original serum.
