Set to make a big splash during San Diego's Saturday lineup, Warner Bros. and TV Guide have teamed up yet again to highlight The CW's lineup of comics-based series, as well as the network's longest-running show, Supernatural. The four collectible covers will hit newsstands and digital platforms on July 18. However, convention attendees will once again be able to pick up copies by visiting the Warner Bros. booth (#4545) beginning with Preview Night on Wednesday, July 19, and continuing through the end of the event on Sunday, July 23.

Featured one one of the four covers are KJ Apa, Lili Reinhart, Camila Mendes and Cole Sprouse from Riverdale, which is currently filming its second season, described as "darker" and "stranger" by Sprouse. The Riverdale crew will take a break from filming, however to attend SDCC on Saturday to premiere exclusive footage from the upcoming second season.

Also debuting on the collectible covers is Cress Williams' Black Lightning, who joins fellow DC TV stars Grant Gustin (The Flash), Stephen Amell (Arrow) and Melissa Benoist (Supergirl). Interestingly, although it has been said that Black Lighting is not a part of the Arrowverse, the character has joined Arrow and The Flash on a cover rather than headlining his own.

Of course, while The CW tends to spotlight its DC TV stars throughout Comic-Con, the long-running Supernatural has returned for yet another cover. The Winchester brothers, Jared Padalecki and Jensen Ackles, are expected to return to tease the show's upcoming 13th season.

The 88-page special issue will include new photos and features spotlighting fan-favorites such as Arrow, The Big Bang Theory, DC’s Legends of Tomorrrow, The Flash, Supergirl and Supernatural. It'll also include first looks at Black Lightning, Krypton, and Titans. As if that wasn't enough, however, the issue will also come with a 10.5-inch by 19-inch pull-out poster from Westworld.

This year, Comic-Con International in San Diego runs Thursday, July 20, through Sunday, July 23. in the San Diego Convention Center, with the traditional Preview Night on Wednesday, July 19.
