New Keroro Sergeant Movie Set for June 2026 Release with Fresh Characters
The wait is finally over for fans of the green alien invaders. The official release date for the much-anticipated film, New Theatrical Version ☆ Sergeant Keroro: Resurrection and Rapid Action: The Earth is in Crisis of Destruction!, has been confirmed. Mark your calendars for June 26th, as that is when the Keroro Platoon will be returning to the big screen. This project is based on the legendary original work by Yoshizaki Kannon, and the excitement levels are already through the roof.
Along with the date, some very interesting news regarding the cast has dropped. Two brand new characters, Arles and Delles (sometimes referred to as Delulu in earlier leaks), have been introduced. These characters are expected to play a massive role in the upcoming plot.

Who are Arles and Delles? Exploring the New Keronite Brothers
From what we have gathered, Arles and Delles are not just random additions; they are the key to the entire movie's story. It has been revealed that they are Keronite brothers, and there is a lot of talk that they might have had some kind of past relationship with the members of the Keroro Platoon. This adds a nice layer of mystery to the narrative. If you are looking to refresh your memory on the series, you should check out this Keroro Sergeant: the ultimate guide to the hilarious alien invasion anime and manga to see how the platoon members usually interact.
This information was officially shared during a special stage event titled "New Theatrical Version ☆ Keroro Sergeant: Revival and Rapid Attack of the Earth is in Crisis of Destruction!" and a public recording of "Keroro Sergeant's Kero! and Radio." These events were held on March 29th at AnimeJapan 2026. Fans who attended were lucky enough to see the original designs for Arles and Delles, which were personally created by Yoshizaki himself.

A Grand Celebration for the 20th Anniversary
This new movie is actually a very big deal because it serves as the 20th anniversary project for the Keroro Sergeant animation. Can you believe it has been 16 years since the last theatrical release in 2010? It is truly a long time coming for the fans who grew up watching these frogs try (and fail) to conquer Pekopon. This Keroro Sergeant: the ultimate guide to the hilarious alien invasion anime and manga really captures why the series has remained so popular even after all these years.
The production team behind this film is also quite impressive. Yuichi Fukuda is going to be in charge of the screenplay and will also serve as the general director. With his experience, we can definitely expect the classic humor and chaos that Sgt. Frog is known for. The plot seems to suggest a "largest-scale battle" ever, which is quite a promise for a 20th-anniversary celebration.
