Slade Wilson (born in 1968), codenamed Deathstroke by A.R.G.U.S., is a former member of the Australian Secret Intelligence Service/ASIS Unit, the former leader of the Church of Blood and the second season's main antagonist. He is also the former friend and ex-partner of the late Billy Wintergreen, the father of Joe Wilson, and one of the former mentors/friend turned enemy of Oliver Queen, friend turned enemy of Sara Lance, and the lover of the late Shado.
During the season 1 flashbacks Slade is an ally of Oliver on the island who taught him most of his combat skills whilst attempting to stop the plot of Edward Fyers with Oliver and Shado. In Season 2 Slade appears in the flashbacks, as a protagonist and secondary antagonist, and present day, as the main antagonist, with a mission of vengeance to take away everything Oliver cares about for him getting Shado killed by Anthony Ivo, working with Sebastian Blood and Isabel Rochev to do so. However, at the end of the season finale, his plan failed, he was cured of the Mirakuru, and he was imprisoned in an A.R.G.U.S. supermax back on Lian Yu.
