Deathstroke

""You said you had something I'd want? You better not be wasting my time.""

- ―Deathstroke and Lex Luthor

Slade Joseph Wilson is one of the world's deadliest assassins and a mercenary-for-hire, operating under the codename Deathstroke. He is one of the adversaries of the Batman and a mutual acquaintance of Lex Luthor.

Originally a soldier in the U.S. Army during the Vietnam War, Slade Wilson was part of an experimental super-soldier program where he gained enhanced strength, agility, healing factor and intelligence. Deathstroke became a mercenary soon after the experiment and rapidly gained a reputation as one of the world's greatest assassins.

Personality
As an assassin, Slade Wilson is cold, blunt, and irascible, being more than willing to leave Lex Luthor's yacht when he warned the latter not to waste his time, but seemed quite interested after hearing his realizing the Batman is Bruce Wayne in response to the Justice League's formation and resurrection of Superman. Deathstroke immensely dislikes insanity and inefficiency, as he was vocally irritated by having to work with Joker in the Knightmare timeline.

Much like Joker, however, Deathstroke is was willing to temporarily team up with his former enemies for the greater good of humanity (or more likely their own personal agenda or reasons at least). Though he is a mercenary, he is show to be willing to do jobs without pay if he has a personal stake in it. As he showed by volunteering to work for Luthor in exchange for the chance to kill Batman.

General

 * In DC Comics, Deathstroke is a recurring enemy of the Teen Titans, and one of the most formidable foes of Batman and Green Arrow.
 * The armor he wears in Josstice League and Zack Snyder's Justice League is identical to the one he sports in the video game, Batman: Arkham Origins. The similarities include the orange color scheme around his chest, a pop-out collar-like neck armor, and heavy shoulder plates with similar design patterns. The only noticeable difference being a black chevron on the top of the movie version's helmet.
 * Joe Manganiello was uncredited for his appearance in Justice League.
 * Joe Manganiello was originally considered for the role of Superman.
 * Before Joe Manganiello was cast as Deathstroke, Stephen Lang, Ron Perlman, and Arnold Schwarzenegger were considered for the role of Deathstroke.
 * It was initially planned for Deathstroke to have his own solo film, but a change in executives at the studio put the film on indefinite hold.
 * According to Joe Manganiello, the character of Deathstroke was originally planned to star in Suicide Squad 2 before James Gunn was hired to direct the film.
 * Deathstroke in the DC Extended Universe is the fifth live-action incarnation of the character, following incarnations portrayed by Antonio Sabàto, Jr, Michael Hogan, Jeffery C. Robinson and Manu Bennett.
 * There is a nod to popular Batman rogue, Ra's al Ghul, on the hilt of one of Slade's swords: an emblem of the League of Shadows.
 * The emblem was actually made for Halo, which is unrelated to DC Comics, but was used on a fan page to represent Ra's. Apparently Manganiello and/or his costume designer didn't realize the difference when pushing to make the connection, but the intention remains.
 * In Justice League, Deathstroke was invited to Lex Luthor's yacht, but instead of being there to take down the Batman, Luthor instead invited him to join a team of supervillains with himself as the head.
