Mirakuru

The Miracle, also known as Mirakuru (ミラクル), is a serum tested on criminals by Sebastian Blood's organization. It seems that Blood wishes to use it to make criminals into something else, or possibly force them to obey him (hence his statement made to Xavier Reed if he was "ready to serve" before administering him with it).

Its exact properties and intended purpose are unclear, though so far every individual seen to have been injected with the serum has suffered convulsions and begun bleeding from the eyes immediately after injection. In order for the serum to have the desired effect, a strong sedative must be administered along with it, otherwise the recipient is likely to die. However, it appears that a person's inherent anger can allow them to survive the Mirakuru's injection without the sedative, as demonstrated with Slade and Roy. Human blood is also apparently a component required to either manufacture the serum or to use it properly.

According to Anthony Ivo in, the Mirakuru was a serum that caused increased strength and rapid cell regeneration created by the Japanese during World War II in hopes of creating an army of super soldiers. They transported their only supply through submarine when it came under heavy fire by the Allied Forces and ran aground on Lian Yu. At some point, Ivo found the submarine and began testing the drug on human subjects.

It is possible that, as Sebastian Blood stated that to fix Starling City, he needed "an army of the strong"; the serum is intended to give those injected with it superhuman strength.

In "Crucible", Xavier Reed is captured by Blood and injected with The Miracle; he dies after bleeding from his eyes.

In "State v. Queen", Cyrus Gold appears to be the only one of a group of Blood's test subjects to survive injection, and when asked by Sebastian Blood how he feels, he said "Stronger".

In "The Scientist", Gold is shown to have super strength and superhuman durability, as implied by the drug's assumed effects. Furthermore, while he defeats Oliver twice, Oliver claims he has killed at least one user of Mirakuru on Lian Yu. He also states that all of Ivo's test subjects are dead, and that he burned the rest of the serum that they found on the Japanese submarine.

In "Three Ghosts", it is shown that Sebastian Blood recreated The Miracle using samples of Slade Wilson's blood.

Trivia

 * Deathstroke in the comics was injected with a experimental serum by the US government which left him in a coma for months. When he awoke the serum had enhanced his body giving him the strength of ten men along with heightened speed, agility, stamina, and reflexes. It also increased his capacity to use up to 90% of his brain at any one time. The serum also provided him with a healing factor in his blood that enabled him to heal from physical injury much faster than a normal person; however, it did have limitations, as he could not heal his missing eye and cannot regenerate entire limbs.
 * The Miracle is similar to other drugs used in DC comics such as Venom a steroidal compound used by Bane to enhance his strength. Venom was derived from Miraclo a serum used by the hero Hourman which lasted only one hour. Another serum used in the comics was Blockbuster which permanently enhanced Mark Desmond and his brother Roland Desmond into hulk like monsters.
 * The Miracle was created by the Japanese during World War II.
