Steppenwolf may not be the only villain to appear in "Justice League," at least according to the latest Tweet from Ben Affleck. The "Batman v Superman: Dawn of Justice" star released a video of Deathstroke on his Twitter, hinting that the villain may show up in the upcoming film.

Affleck posted the video to his personal account without comment, leaving fans to speculate over the footage.
This tease follows on the heels of "Arrow" executive producer Marc Guggenheim's comments about the character, who appeared as a primary antagonist in the first two seasons of the popular CW series. In February, Guggenheim told fans, “The character of Slade Wilson [Deathstroke] is currently tied up in another DC project." From the looks of Affleck's video, it appears that unnamed DC project is "Justice League."
Created by Marv Wolfman and George Perez, Deathstroke originally appeared as an antagonist in "The New Teen Titans" #2. A mercenary and assassin, the character has gone on to become a villain for multiple other characters, up to and including Green Arrow. In addition to "Arrow," Deathstroke has appeared in "Lois & Clark," "Smallville," the animated "Teen Titans" television series, "Young Justice," and "Beware the Batman."
“Justice League” stars Ben Affleck, Henry Cavill, Gal Gadot, Ezra Miller, Jason Momoa, Ray Fisher, Amy Adams, Jesse Eisenberg, Amber Heard, Jeremy Irons and J. K. Simmons and opens on November 17, 2017.
