General Motors has filed two trademark applications that have car-industry websites speculating the company may be rolling out an automotive tie-in to the upcoming Batman v Superman: Dawn of Justice.

GM Authority was the first to pick up on filings by the Detroit giant for "Krypton" and "Camaro Krypton," for "motor and land vehicles." While that blog and others note that krypton is the name of a chemical element, the capitalized version is more widely associated with the home planet of Superman.

Special-edition cars tied to popular movies or television shows are certainly nothing new: Hyundai released one for AMC's The Walking Dead (part of the automaker's larger sponsorship of the hit series); Kia produced a one-off "X-Car" to help promote X-Men: Days of Future Past in Australia; and Nissan earlier this year wheeled out the limited-edition "Thousand Serena" in honor of One Piece.

According to GM Authority, GM's Chevrolet brand will reveal its sixth-generation 2016 Camaro on Saturday, when we could learn just what's planned for Krypton.
