In an internet-breaking moment, Ben Affleck took to Twitter today and posted a snippet of DC’s most ruthless mercenary/assassin, Deathstroke, clad in heavy armor and his signature black and orange mask. The video seemingly confirms the presence of the said character for the upcoming Justice League movie.

It’s highly unlikely that the snippet was shot from Affleck’s Batman shoot, since that movie hasn’t begun production yet; while the Justice League movie is already set to wrap production in a couple of weeks’ time.

Details on the actor behind the mask have yet to surface.
