DC superhero shows The Flash and Arrow are back on The CW once again, with the first episode of Arrow Season 4 nodding to the events of The Flash‘s Season 2 premiere. The two pillars of the growing shared superhero TV universe have garnered an enthusiastic fanbase, and during New York Comic Con this week Warner Bros. Television decided to tease the biggest elements of what to expect from the current seasons.

The Flash‘s Season 2 arc is tied into the fallout from the Speed Force singularity that nearly destroyed Central City in the Season 1 finale, and which created a portal between the universe that we know and an alternate universe. Through that doorway comes a new villain called Zoom (Tony Todd), who is determined to have Barry Allen (Grant Gustin) killed, as well as another version of The Flash: Jay Garrick (Teddy Sears).

All this is explained the sizzle reel for The Flash Season 2, which was screened during Warner Bros. Television’s Sunday panel. The video kicks off with footage that viewers will already have seen, of Barry battling the Atom Smasher in the season premiere, before jumping into rapid-fire clips showing what’s still to come. There’s the introduction of Kendra Saunders a.k.a. Hawkgirl (Ciara Renée), scenes of Zoom battling Barry while speaking in Todd’s characteristically deep voice, and a brief clip of Barry meeting police offer Patty Spivot (Shantel VanSanten).

Arrow isn’t going to let the speedster hog all the attention, though. WBTV also screened a sizzle reel for Arrow Season 4, which brought its own share of tantalizing teases. Thea (Willa Holland) seems to be suffering from the after-effects of being resurrected in the Lazarus Pit, Sara Lance a.k.a. White Canary (Caity Lotz) is also back after taking a dip in the life-giving waters, and there’s even a shot of Matt Ryan reprising his role as magician John Constantine and seemingly confirming that NBC’s short-lived supernatural series Constantine is another extension of The Flash and Arrow‘s shared universe.

There’s almost too much in these two trailers to talk about: Echo Kellum in what looks like a fun role as Curtis Holt a.k.a. Mr Terrific; Martin Stein (Victor Garber) bursting into blue flames in a manner that doesn’t look comfortable; J.R. Bourne as card-throwing villain Double Down; metahumans galore, and mainstay villain Captain Cold (Wentworth Miller) back in the mix. All in all, it looks like we’re in for an action-packed fall and winter on The CW.

Did you spot something in one of these trailers that you can’t wait to see? Let us know what you’re looking forward to most in the comments.

Season 2 of The Flash airs Tuesdays at 8/7pm central; Season 4 of Arrow airs on Wednesdays at 8/7pm central; Legends of Tomorrow begins in 2016.
