Warner Bros.' oversized totes, considered the must-have accessory for Comic-Con International, are returning to San Diego -- and they're wearing capes. This year's version is a backpack, rather than a traditional bag, so the capes make sense, at least visually. Don't worry, though, they're detachable, and can be worn separately.

More than 130,000 backpacks will be given for free to attendees throughout the convention, promoting Warner Bros. television series Arrow, Teen Titans Go! (complete with Beware the Batman cape), The Big Bang Theory, The Following, Revolution, Supernatural and The Vampire Diaries, the classic Batman TV series, the DC Universe Original Animated Movie Justice League: The Flashpoint Paradox, and the forthcoming films Godzilla, The LEGO Movie and 300: Rise of an Empire.

Each backpack features the official Comic-Con 2013 design on one side, and the Warner Bros. property on the other. Unfortunately, art wasn't released for all of the backpack designs, but you can get a pretty good taste below.

Comic-Con International kicks off Wednesday with Preview Night.
