While no new footage is in the trailer, that’s only because they released it this week; they did lean on clips from the latest episodes of The Flash and Arrow, at least (even if they also went back far enough that some of the villains seen here are dead).

The Flash airs Tuesday nights at 8 p.m. ET/PT, followed by Supernatural at 9. Arrow airs Wendesday nights at 8 p.m. ET/PT.
