Ben Affleck has taken to social media to unveil a familiar villain we’ve had the joy of seeing in the comics, Teen Titans and Arrow. And it is a dousy; in the video Affleck teases the coming of Slade Wilson aka Deathstroke for Justice League. Maybe even the Batman solo film. Way to go Batman.

Justice League synopsis reads:
Fuelled by his restored faith in humanity and inspired by Superman’s selfless act, Bruce Wayne enlists the help of his newfound ally, Diana Prince, to face an even greater enemy. Together, Batman and Wonder Woman work quickly to find and recruit a team of meta-humans to stand against this newly awakened threat. But despite the formation of this unprecedented league of heroes—Batman, Wonder Woman, Aquaman, Cyborg and The Flash—it may already be too late to save the planet from an assault of catastrophic proportions.
