When it comes to Comic-Con, Warner Bros. TV holds the keys to the kingdom! Now you can too!

Plus the upcoming Thriller Time After Time is included on this exclusive set, to be featured on nearly 40,000 Limited-Edition Collectible Hotel Keycards that you can only get if you attend the big event, and are staying at one of the nearby participating hotels.

Which Super Hero will you take back to your room? That's the big question as Warner Bros. TV prepares to hit Comic-Con 2016 with a vengeance. Will it be Supergirl? The Flash? The Green Arrow? One of the Waverider's crew? A resident of Gotham? Or maybe even H.G. Wells!

During Comic-Con 2016, hit DC series Arrow, DC's Legends of Tomorrow, The Flash, Gotham and Supergirl, as well as the upcoming new thriller Time After Time, will be individually featured on limited-edition collectible keycards at top hotels throughout the San Diego area.
