Deathstroke (Arrowverse)

"To kill you now would be a mercy. You cannot die until you have suffered the same way I have suffered, until you have known complete despair, and you will, I promise."

- Slade Wilson "Pick a sword. I like swords."

- Slade Wilson

Slade Wilson, codename Deathstroke, is a former member of ASIS and the leader of the Blood Cult in Starling City. In 2006, Slade and his partner Billy Wintergreen were assigned to free Yao Fei, a Chinese general who was purposely imprisoned by his own government to cover up a massacre commited in 1998. After Slade's plane was shot down, Wintergreen betrayed Slade to Edward Fyers, who held Slade captive for several months. Yao Fei eventually freed Slade, and the two joined together by hiding in the wreck of Slade's plane.

Six months later, Yao Fei sent the shipwrecked Oliver Queen to Slade, who trained the upstart billionaire playboy in combat. Ultimately, Slade and Oliver managed to take the air field Yao Fei and Slade had intended to take, but at the cost of Yao's life yet saving his daughter, Shado. Slade, harboring small romantic feelings for Shado, choose to keep his distance while Oliver pursued a relationship with her. After investigating a disturbance in a proximity detector, Slade is mortally wounded by an explosion that scarred the right side of his face. Oliver, Shado, and a newly revealed to be alive Sarah Lance seek out the Mirakuru, a superhuman serum that Anthony Ivo is also seeking out. After administering the serum to a dying Slade, Oliver and the others are captured by Ivo and Shado is killed. Slade, soon discovering the incredible effects of the Murakuru serum, goes on a rampage across the island, quickly defeating several men while displaying his new found strength by bending the barrel of a rifle. Besting Ivo's crew with ease alongside Oliver and Sarah, Slade discovers that Oliver choose Sarah over Shado and savagely attacks him. Slade announces himself the captain of Ivo's men, intending to make Oliver suffer.

Desptie his best efforts, Slade is later bested by Oliver after the latter shoots an arrow in Slade's eye. Oliver, thinking he is victorious, continues to attempt to survive on Lian Yu. It is later revealed that Slade, now a successful businessmen, has come to Starling City to devastate Oliver and make him suffer like Slade.
