The CW’s Arrow and The Flash both returned last week with their respective fourth and second seasons, and to celebrate, the network debuted new sizzle reels for the upcoming season today at New York Comic Con. If you’re bummed you couldn’t make it to NYCC, or just a fan feeling feeling impatient for the next episodes, you can watch them here now.

The Flash‘s sizzle reel is, well, sizzling, giving us our first look at both new ally Jay Garrick (AKA the original Flash), and this season’s big bad, Professor Zoom. Zoom, we now know, has been hopping between alternate dimensions on a quest to eliminate all other super-speed having people that have ever existed. Meanwhile, Jay Garrick has traveled to Barry Allen’s world from one of those alternate universes to warn him of the threat. More to come as the season unfolds.

The Arrow trailer, meanwhile, is heavy on scenes from the season premiere, but it does give a closer look at season 4 big bad Damien Darhk, played by Neal McDonough. Leader of the criminal organization H.I.V.E., he’s apparently had a hand in many of the major events of the series from behind the scenes, and now seeks to destroy Star City for as yet murky reasons. You can see for yourself here.

The Flash airs Tuesday; Arrow airs Wednesday.
