Now that Barry and Cisco have shown up on Supergirl to get the ball rolling, The CW has created a trailer for Tuesday night’s episode of The Flash.
The episode is called “Invasion!” and characters from Supergirl, Arrow, and DC’s Legends of Tomorrow all guest star! Heroes v Aliens and it’ll probably all be Barry’s fault!
Here’s the new promo trailer; if you’ve watched this week’s Supergirl and want to talk about it with other fans, come by our forum at KSiteTV! Photos from The Flash episode can also be found below.
