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 coast-to-coast journey from Spartanburg, South Carolina, to Los Angeles, California. The 53-foot tractor-trailer, designed to resemble He-Man’s loyal steed Battle Cat, features a fully functional commercial kitchen capable of serving thousands at each stop. The activation kicks off April 21 and will culminate with fan events at Fiesta Broadway on April 26 in Los Angeles, one of the largest Cinco de Mayo celebrations in the country.
“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 diner will offer free tastings of new Masters of the Universe menu items, photo opportunities, and movie swag at select stops.
Fans who spot the truck on its route can share a picture using #roarinacrossUSA and tag @dennysdiner with #iagree to receive exclusive diner deals, including Free Eternia Everyday Value Slams and Free Skeletor’s Dark Shakeverse milkshakes, available on a first-come, first-served basis. The promotion runs from April 22 to June 8, 2026, or while supplies last. Additionally, themed co-branded t-shirts are available on DinerDrip, including designs like “By the Power of Grayskull I Have the Pancakes.”
The route includes stops in Memphis, Tennessee; Oklahoma City, Oklahoma; and Albuquerque, New Mexico, before arriving in Los Angeles. Denny’s has been a longtime sponsor of Fiesta Broadway, aligning with its commitment to community engagement. The partnership with Masters of the Universe underscores Denny’s strategy to leverage pop culture to drive customer engagement and brand visibility. As the movie premieres on June 5, the Mobile Diner serves as a mobile marketing powerhouse, blending nostalgia with modern promotional tactics to attract both loyal fans and new customers.
