Denny’s has unveiled a custom-wrapped Masters of the Universe Mobile Diner in partnership with Mattel, Inc. and Amazon MGM Studios, embarking on a cross-country journey from Spartanburg, South Carolina, to Los Angeles, California. The 53-foot tractor trailer is designed to resemble Battle Cat, the armored green tiger steed of He-Man, and features a fully functional commercial kitchen capable of serving thousands at each stop. This activation leads up to the theatrical release of the Masters of the Universe movie on June 5.
“At Denny’s, we believe every meal should feel like a victory. By bringing the world of Eternia to life through our Mobile Diner, we’re giving fans a chance to experience the power of Grayskull beyond our restaurant booths,” said Chris Bode, President & CEO, Denny’s. “This journey is our way of celebrating the fans whose passion has kept this legend alive, rewarding their loyalty with epic prizes as we charge toward the Masters of the Universe premiere.”
The Mobile Diner will make stops in Memphis, Tennessee; Oklahoma City, Oklahoma; and Albuquerque, New Mexico, before arriving in Los Angeles for Fiesta Broadway on April 26. At Fiesta Broadway, one of the largest Cinco de Mayo celebrations in the country, Denny’s will offer free tastings of its new Masters of the Universe menu items, photo opportunities, and movie swag. Denny’s has been a sponsor of Fiesta Broadway for years as part of its commitment to community engagement.
