Deathstroke

Deathstroke (Slade Joseph Wilson) is a DC Comics supervillain who appears in American comic books. Deathstroke the Terminator debuted in The New Teen Titans issue 2 in December 1980, created by Marv Wolfman and George Pérez. He is frequently represented as one of the DC Universe's deadliest and most costly assassins and is a major foe of various superhero teams, including the Teen Titans, Titans, and Justice League. Individual heroes such as Dick Grayson (as Robin and subsequently Nightwing), Batman, and Green Arrow face him as well. Jericho, two incarnations of Ravager (Grant and Rose Wilson), and Respawn are all descendants of Deathstroke.

Wizard magazine listed the character as the 24th Greatest Villain of All Time, and IGN ranked him as the 32nd Greatest Comic Book Villain of All Time. He has appeared in a number of media adaptations, including several Batman-related productions and the Teen Titans animated series, where he is voiced by Ron Perlman. Deathstroke has been played in live-action by Manu Bennett on The CW's Arrowverse television show, Esai Morales as the main antagonist in the second season of the DC Universe series Titans, and Joe Manganiello in the DC Extended Universe with a cameo in the 2017 film Justice League.
