Get ready, frog fans! The brand-new "Sgt. Frog" movie, "New Movie Version☆Sgt. Frog: Resurrected and Immediately Facing Earth's Extinction Crisis!", is hitting Japanese theaters on June 26, 2026. The official release of a special collaboration trailer with "Mobile Suit Gundam" has reignited buzz for this 20th-anniversary animation project. 
In the newly released sneak peek, the Keroro Platoon is locked in an intense battle against mysterious invaders, struggling against overwhelming enemy power. Just when things look dire, Keroro's beloved RX-78-2 Gundam makes a dramatic entrance, turning the tide! But the danger isn't over yet: another familiar red mobile suit, Char's Zaku II, also appears in the trailer, officially blocking the path of the Keroro Platoon and the Gundam.
"Sgt. Frog" has long been famous for its hilarious parodies and homages to various anime, with "Mobile Suit Gundam" being a frequent target. Protagonist Keroro himself is a hardcore Gunpla enthusiast, and Gundam-related gags have popped up countless times throughout the series. However, despite the anime being on air for 22 years, officials state this is the very first official collaboration between "Sgt. Frog" and "Mobile Suit Gundam."
Beyond the trailer, officials also dropped collaborative illustrations personally drawn by Mine Yoshizaki, the original creator of "Sgt. Frog," and Yoshikazu Yasuhiko, the character designer for "Mobile Suit Gundam." Yoshizaki's piece pays homage to the "Mobile Suit Gundam Movie Trilogy" with a Keroro-fied composition, while Yasuhiko delivered a dream-come-true image of Amuro, Char, and Keroro side-by-side.
With the RX-78-2 Gundam and Char's Zaku II making their appearance directly in the movie footage, this collaboration isn't just a simple crossover; it's woven right into the film's plot, making it a must-watch for fans of both franchises.
