People of Earth (Pekopon)… they have returned.
After years of silence, one of Japan’s most iconic and beloved comedy anime franchises is officially back.“New Movie Edition☆Sergeant Keroro Is Back and the Earth Is on the Brink of Destruction!” is set to arrive in Summer 2026, marking the explosive revival of Keroro Gunso (also known internationally as Sgt. Frog).
Announced as part of the 20th anniversary anime project, this new theatrical film doesn’t just continue the legacy — it
boldly declares the “first year of the new Keroro era.”
And yes, the invasion is finally back on schedule… sort of.
🐸 What Is Sergeant Keroro (Keroro Gunso)?
Originally serialized in Monthly Shonen Ace (KADOKAWA) in 1999, Keroro Gunso is the hugely popular manga created by Mine Yoshizaki.
Over the years, the franchise has achieved:
14+ million copies sold worldwide
A long-running TV anime series
Multiple animated films (five theatrical releases)
A massive international fanbase across all ages and genders
The story centers on Keroro, a frog-like alien sergeant from planet Keron, sent to Earth to invade — only for the plan to fall apart spectacularly.
Instead of conquering Earth, Keroro and his platoon:
Lose their invasion equipment
End up freeloading with a human family
Spend more time building model kits than planning world domination
That contrast — grand invasion goals vs absolute incompetence — is what turned Keroro Gunso into a cultural phenomenon.
🎬 A Brand-New Keroro Gunso Movie for a New Era
The upcoming film is officially titled:
New Movie☆Sergeant Keroro: Resurrection and the Threat of Earth’s Destruction!
This movie is not a remake or recap.
It is a fully new theatrical entry, positioned as the starting point for the franchise’s next phase.
The announcement confirms:
A large-scale action-comedy story
The biggest battle in Keroro Gunso history
A new invader entering the scene
High-stakes chaos unfolding in the Reiwa era
In short: the frogs are back — and this time, things might actually get serious.
📖 Story: The Invasion No One Is Ready For
Despite being invaders, the Keroro Platoon has once again fallen into a life of laziness.
Days pass.
Plans stall.
The invasion remains… unfinished.
But suddenly, mysterious phenomena begin appearing all across Japan. Strange signs. Unexplained symbols. Ominous letters scattered everywhere.
For the first time in a long while, the Keroro Platoon senses something truly wrong.
Forced to act, they rise — not just to protect Earth, but to protect their pride as invaders.
Key story questions teased so far:
What do the mysterious letters appearing everywhere mean?
Who is the new invader that confronts Keroro?
Is Earth finally facing a real threat — not comedic incompetence?
Can the Keroro Platoon save a planet they were supposed to conquer?
This is described as the largest-scale conflict in the history of Sgt. Frog.
🎭 Returning Characters & Voice Cast (Original Voices!)
One of the biggest highlights: the original voice cast is back, preserving the heart of the franchise.
