Sgt. Frog (Keroro Gunsou) watch order
Sergeant Keroro, a frog-like alien sent to scout Earth for invasion, gets abandoned by his army and ends up living with the Hinata family, doing chores and building Gundam models while every invasion plan fails. A 358-episode gag show from 2004 to 2011, five films, a 2014 short series and a 2026 reboot with a new cast, all based on Mine Yoshizaki's manga.
First time? Either start the original Sgt. Frog from episode 1 (it's episodic, so stop whenever you like; the English dub covers episodes 1–78) or jump straight into the 2026 reboot KERORO☆, which retells the story from the beginning. The films are standalone extras.
First-timer order
Release order, with the two 2014 and 2026 side projects moved to the end. Really, this is a show to dip into: watch the opening episodes, then as much of the TV series as you enjoy, and add the films whenever you want a longer story. Or skip all of it and start with KERORO☆.
- Sgt. Frog (Keroro Gunsou)
The original series: seven Japanese seasons of mostly two-segment gag episodes, with recurring characters rather than a plot, so you can dip in anywhere after the first few. The staff and tone shift at episode 104. The English dub (Funimation, now on Discotek's Blu-rays) covers episodes 1–78 only.
- Sergeant Keroro: The Super Duper Movie (optional)
The first film: Keroro and Fuyuki accidentally release Kiruru, an ancient weapon that feeds on negative feelings, and mistrust spreads across the city. Standalone; assumes you know the cast. Optional.
- Sergeant Keroro: The Super Duper Movie 2, The Deep Sea Princess (optional)
On a beach holiday Natsumi is carried off to an undersea kingdom by the alien Meru, who wants her as his princess. Standalone. Optional.
- Chibi Kero: Secret of the Kero Ball!? (optional)
A 17-minute 3DCG short shown with the second film: tadpole-aged Keroro, Giroro, Zeroro and Pururu get sucked into the Kero Ball. Optional.
- Sergeant Keroro: The Super Duper Movie 3, Keroro vs. Keroro Great Sky Duel (optional)
A ruin at Machu Picchu, a mysterious girl and a Dark Keroro, the strongest enemy the platoon has faced. The longest film. Standalone. Optional.
- Musha Kero: Sengoku Ranstar Great Battle (optional)
A 14-minute short shown with the third film, with the platoon in the samurai world of Ranstar. It's the lead-in to the Musha Kero storyline that the TV series picks up in its fifth season. Optional.
- Sergeant Keroro: The Super Duper Movie 4, Gekishin Dragon Warriors (optional)
Giant dragon tails appear around the world and Tamama vanishes; the search leads to Mont-Saint-Michel and a legendary book. Standalone. Optional.
- KeroZero: Departure! All Members Assemble! (optional)
A 15-minute short shown with the fourth film: "episode 0", the platoon leaving Keron for Earth. Chronologically the earliest story, but it's written for existing fans. Optional.
- Sergeant Keroro: The Super Duper Movie 5, The Miraculous Space-Time Island (optional)
A carving that looks like Keroro leads him and Fuyuki to Easter Island, the Mana spirits and the legendary AkuAku. The last of the original films. Standalone. Optional.
- KERORO☆ (Sgt. Frog☆)
The 2026 reboot, airing from October 3: Bandai Namco Pictures retells the story from Keroro's arrival at the Hinata house with a brand-new cast, under chief director Nobuhiro Kondo from the original series. Streams on Crunchyroll. Needs nothing before it.
- New Sgt. Frog the Movie: The Earth Is in Mortal Peril as Soon as We Come Back! (optional)
A 20th-anniversary film that opened in Japan on June 26, 2026, from Bandai Namco Pictures with the original voice cast. Written and supervised by Yuichi Fukuda. No international release had been announced as of October 2026. Optional.
- Keroro (2014) (optional)
A short Flash-animated series (about five minutes an episode) made for Animax's Keroro Hour, with the original voice cast but new designs, adapting later manga material with characters the 2004 series never reached. A separate curiosity rather than a sequel. Optional.
Story order
There's barely a timeline to follow. KeroZero is the platoon's departure for Earth, so it comes first on paper; the films happen somewhere during the TV run and the Musha Kero short leads into the TV series' fifth-season samurai storyline. Keroro (2014) adapts later manga, and KERORO☆ starts over, so both sit at the end.

Explained
358 episodes. Where do I start, and can I skip?
Start at episode 1 and feel free to skip around: it's an episodic comedy with no plot to lose, and only a few light storylines (the Musha Kero samurai episodes, the Shurara Corps) run across more than an episode. The staff changed at episode 104, which is the one real shift in tone. Stop whenever you've had enough.
Do I need the films or the shorts?
No. All five Super Duper Movies are standalone side stories that only assume you know the characters. The three shorts were cinema extras; Musha Kero is the only one with a link to the TV series (its fifth-season samurai storyline), and KeroZero is a prequel made for fans.
What's the difference between the 2026 film and KERORO☆?
Two separate projects. The June 2026 film is a 20th-anniversary movie with the original voice cast. KERORO☆, the TV series that started in October 2026, is a reboot with a completely new cast that retells the manga from the start. Watching the old show first isn't required for either.
How much is dubbed in English?
Funimation dubbed episodes 1–78 (plus a test dub with renamed characters that was dropped), then put the dub on hold in 2013. Discotek's Blu-rays carry all 358 episodes with that dub where it exists and subtitles for the rest. The films are subtitled only (Discotek's collection, August 2026). KERORO☆ streams subtitled on Crunchyroll, which also carries the 2004 series.
What is Keroro (2014)?
Twenty-three Flash-animated shorts made for Animax, with the old cast but new designs, adapting later manga chapters with characters the 2004 anime never got to (New Keroro, Tomosu). It isn't a sequel to the 2004 series and a hinted second season never happened.
