Denny’s has unveiled a custom-wrapped Masters of the Universe Mobile Diner, created in partnership with Mattel, Inc. and Amazon MGM Studios, as part of a coast-to-coast activation leading up to the theatrical release of the Masters of the Universe movie on June 5. The 53-foot tractor-trailer, designed to resemble the iconic Battle Cat, features a fully functional commercial kitchen capable of serving thousands at each stop. The journey began in Spartanburg, South Carolina, on April 21 and will conclude in Los Angeles, with planned stops in Memphis, Oklahoma City, and Albuquerque.
“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 of Denny’s. Fans are invited to spot the truck and share photos on social media using #roarinacrossUSA and #iagree to receive exclusive diner deals, including free Eternia Everyday Value Slams and Skeletor’s Dark Shakeverse milkshakes, available on a first-come, first-served basis.
The mobile diner will make a notable appearance at Fiesta Broadway on April 26 in Los Angeles, one of the largest Cinco de Mayo celebrations in the country. Denny’s, a long-time sponsor of the event, will offer free tastings of the new Masters of the Universe menu items, photo opportunities, and movie swag. This activation underscores Denny’s commitment to community engagement and brand partnerships that resonate with fans.
In addition to the mobile diner, Denny’s has released co-branded merchandise, including t-shirts with slogans like “By the Power of Grayskull I Have the Pancakes,” available at DinerDrip in limited quantities. The promotion runs from April 22 to June 8, 2026, or while supplies last. Denny’s Corp., based in Spartanburg, S.C., operates 1,438 global restaurants, including locations in 14 countries, and continues to innovate with virtual concepts like The Meltdown and The Burger Den.
