Slade Wilson was given enhanced abilities as part of a military experiment, and has such confidence in his skills as a mercenary and assassin that his chosen costume highlights the fact that he only has one eye. Adept at both sword and gunplay, his superhuman physical abilities are matched by his tactical genius and his facility for manipulating both allies and enemies alike.
Deathstroke emerged from the inter-universal conflict both wiser and more cautious. Assassins from another universe would be unwanted competition. To maintain superiority, Deathstroke created a band of powerful assassins outfitted in his image. He now serves as Grand Master of this fearsome DeathStrike Clan.
