Sgt. Frog, known in Japan asKeroro Gunso (ケロロ軍曹,Keroro Gunsō, lit. "Sergeant Keroro"[a]), is a Japanesemanga series written and illustrated byMine Yoshizaki. It was launched inMonthly Shōnen Ace in April 1999. The story follows the attempts of a platoon offrog-like alien invaders to conquerEarth. Sergeant Keroro, the titular character, is the leader of the platoon, but is at the mercy of a human family of three after being captured by them. Keroro is forced to do meaningless chores and errands for the family after his army abandons his platoon onEarth. The series was later adapted into ananime television series bySunrise, which ran for358 episodes from April 2004 to April 2011. A second 23-episode series was broadcast from March to September 2014. A new anime project has been announced.
The manga was released in North America byTokyopop from March 9, 2004 to May 10, 2011 (for a total of 21 volumes), and later digitally byViz Media since December 2014. A first English dub of the anime series aired on the Southeast Asian TV channelAnimax Asia in 2008, with the titleSergeant Keroro;Funimation Entertainment released a second 78-episode English dubbed version in North America in 2009, which aired asSgt. Frog onCrunchyroll,Funimation and later onNetflix, as well as on DVD sets.Discotek Media re-released the Funimation dub inSD Blu-ray in 2021. In 2005, the manga received the 50thShogakukan Manga Award for thechildren's manga category.
The Keroro Platoon is a group of five, froglike alien soldiers from Planet Keron. They mean to conquer “Pekopon” (their name for "Earth") but fail every time they try. Their leader, Sergeant Keroro, is incompetent and has little interest in conquering Pekopon. Instead, he likes making plasticGundam models, watching TV, or coming up with schemes to make money. The four other members of the platoon are: adorable but violent Private Second Class Tamama; bellicose yet tenderhearted Corporal Giroro; intelligent but mischievous Sergeant Major Kururu; and disciplined but traumatized Lance Corporal Dororo.
The largest obstacle in the way of their mission is the Hinata Family, who must take care of the Keroro Platoon due to the Keron Army deserting the latter on Earth. Keroro is kept busy with manual labor and constant abuse, primarily from the family daughter, Natsumi. Each member of the platoon finds himself in the care of a human: Giroro's is Natsumi Hinata, whom he falls in love with; Keroro's is Fuyuki Hinata, who considers the sergeant his only true friend; Kururu's is Mutsumi Saburo, who's just as mischievous as him; Dororo's is Koyuki Azumaya, a fellow ninja; and Tamama's is Momoka Nishizawa, who's just as bipolar as him. All are tied to the Hinatas in some way throughout the events in the anime and manga.
Sgt. Frog is published in Japan byKadokawa Shoten, serialized in the magazineMonthly Shōnen Ace, and was published in English byTokyopop. The manga, first aimed at the older audience (teens/adults) from the first to the seventh volume, was toned down after the anime adaption started (since the TV series was a family show). However, the manga still maintains suggestive comedy that only the more mature audiences understand in present volumes.Tokyopop initially held the American rights to theSgt. Frog manga until 2011 when the company ceased operations. By the time their publication ended, they had published 21 volumes. Their release of the manga have censored nipples drawn in some scenes, in order to get away from the OT (Older teen) rating and maintaining its Teen rating.[citation needed]Viz Media relicensed the manga for digital release on December 16, 2014.[3]
To commemorate the 20th anniversary of the series, the November issue ofShōnen Ace announced the launching of a new manga titledChō Keroro Gunsō UC: Keroro Robo Daikessen (Super Sgt. Frog Ultra Cool: Keroro Robo's Epic Climactic Battle) on the next issue, on sale October 26, 2018. The manga is created by Yūtarō Shido, while Mine Yoshikizaki being credited as original author.[4]
The anime series started airing onTV Tokyo in 2004 and ended in 2011. The anime is produced bySunrise,NAS, and TV Tokyo and has also been aired onAnimax,Cartoon Network Japan, andTXN. Seven seasons have been created during its seven-year run. Unlike the manga which is aimed at older audiences, the anime adaptation has been toned down to a level suitable for family audiences.
The anime ran almost year-round, with each season beginning in the first week of April and ending on the last week of March. The first season aired on Saturdays, but the show was moved to Fridays for the second and third seasons. The show returned to Saturdays for seasons four, five and six, and the final season aired on Sundays.
The term "Pokopen", and "Pokopenjin" are both derogatory words the Japanese historically used to describeChina andits people during theSino-Japanese Wars; thus, they were changed to "Pekopon" & "Pekoponjin" respectively.
The first English-language dub of the show to be released was entitledSergeant Keroro and aired onAnimax Asia, a pay TV channel received in multiple countries in Southeast Asia, including Indonesia, Malaysia, the Philippines, Singapore, and Thailand. It premiered in 2008.[5][6]
In the United States,ADV had previously announced they had acquired exclusive rights to an English dub ofSgt. Frog[7] (for $408,000[8]). However, on July 4, 2008, it was announced that rights to the English release were transferred toFunimation Entertainment.[9]
ADV Films had originally added a brief teaser page to their website, announcing their licensing of the anime. The site turned to static before playing a short clip of Keroro dancing to "Afro Gunso," then leaving the message "hacked by the frog."[10] This was followed by a press release from ADV on November 20, 2006, stating that they had licensed all Sgt. Frog properties (except the manga, which was already licensed byTokyopop) for the US.[7] It was once confirmed that the anime dub would be released on DVD in the United States in February 2007. However, ADV Films had never confirmed a release date.[11] ADV announced at the 2007San Diego Comic-Con that the US release date had been delayed because of TV negotiations but would not comment on which networks they were talking to. In a DVD included with the December issue of Newtype USA was an English-language trailer for Sgt. Frog released by ADV, with voices for Keroro (said to be voiced byVic Mignogna[12]), Natsumi, Fuyuki, Aki, and the narrator. ADV was 90% done on getting a deal with the show, though they created a separate team to work specifically on it that included people fromSummit Entertainment (the company that worked with4Kids Entertainment during the time they hadPokémon). They had dubbed three episodes, but they were dubbed three times because ADV created three different pilot-packages for television to see which one worked the best. They made an otaku/fan pilot, a mass-market pilot, and a kids' pilot. They received positive responses from three different networks.Cartoon Network liked the mass-market pilot, whileNickelodeon liked the kids' pilot. Nickelodeon told them that they would air the show if ADV got the merchandising rights. However, as of July 4, 2008, the English license for the first 51 episodes of the Sgt. Frog anime was transferred toFunimation Entertainment through a deal withSojitz.[9]
Funimation released a dubbed version of episode 12B as a test onYouTube to be reviewed by the viewers.[13] Many instances of regional name changes were observed; Natsumi is renamed Natalie, and Giroro's cat was renamed "Mr. Furbottom," (despite being female). Additionally, the word Pekopon was changed to Planet Wuss, Pekoponians were referred to as Wussians, Keron was changed to Frogulon and Keronians were called Frogulonians respectively. The extra-terrestrial frogs' names remained the same as the Japanese version, though shortened by one syllable (e.g. Keroro changed to Kero, Tamama to Tama).[14] The test episode had mixed reviews by fans involving the voice acting, jokes, and name changes.
At Otakon 2009, the first five episodes ofSgt. Frog were screened, where the original versions of the various names that were changed were used. The voice actor for Sergeant Keroro in the test video,Chris Cason, was swapped out for Sergeant Major Kululu's test actor,Todd Haberkorn. Kululu was changed toChuck Huber, and the narrator also appears to have been changed. FUNimation stated at their panel that they were going to keep the anime as similar as possible to its Japanese counterpart, and claimed to only change references from Japanese pop culture (save for those Americans were already familiar with) to references from American pop culture. Those present at the showing seemed to enjoy the changes, and the reception of the official dub was very positive. On February 19, 2011, Funimation announced atKatsucon that they had licensed more episodes of Sgt. Frog.[15]
According to Funimation, as of February 2013, the English dub ofSgt. Frog is "now on hiatus".[16]
On July 31, 2009, Funimation added the first 4 dubbed episodes of the series to their online video portal. After a considerable delay following between the release of the first dubbed episodes, Funimation began making dubbed episodes other than the first 4 available on the portal. Currently, the first 51 subtitled episodes are available on the Funimation video portal andHulu. The 51 dubbed episodes later expired, although they were all later placed back on the portal and on Hulu.[17] The show is rated TV-PG on the DVDs and on Hulu. Unlike the other versions released outside Japan, the US version remains uncut.
The episode distribution scheme has been slightly changed from the Japanese Region 2 release. Although the first 51 episodes are known as "Season 1" in Japan,[18] Funimation has divided the episodes into a "Season 1" and a "Season 2". The Season 1 Part 1 DVD set was released September 22, 2009. It contains episodes 1 through 13,[19] Season 1 Part 2 was released on November 24, 2009, and contains episodes 14 through 26.[20] Season 2 Part 1 was released on January 26, 2010, containing episodes 27–39.[21] In addition, Season 2 Part 2 was released on March 30, 2010, containing episodes 40–51.[22] The first two boxsets were re-released into one Season 1 set on March 29, 2011.[23] The complete Season 2 set followed up on April 26, 2011.[24] Season 3 Part 1 was released to DVD by Funimation beginning on July 26, 2011, containing episodes 52–65.[25] Season 3 Part 2 was released to DVD on August 16, 2011, containing episodes 66–78.[26] A complete Season 3 boxset containing episodes 52-78 was released on November 13, 2012.[27] On all of the box sets, it states, "from the creators of the Gundam series". This is relatively incorrect because Sunrise did not create the Gundam series, they produced it, so it should say "from the studio that brought you Gundam". The creator of Gundam isYoshiyuki Tomino. After the Funimationhome video sets went out of print,Discotek Media re-licensed the home video rights.[28]
All three seasons were available on Netflix streaming as of December 2011; however, the first two seasons, and the first half of the third, were removed without warning in January 2013,[29] before the series was completely removed in April of the same year.
On January 7, 2014, it was announced that a newFlash anime television series entitled "Keroro" would premiere onAnimax on March 22 of that year.[30] Haruki Kasugamori is the director of the series at Sunrise and the animation studio Gathering is providing assistance with the animation. The series airs during the programming block, Keroro Hour, which airs both the series and reruns of Sgt. Frog. The series features new character designs and includes the characters, New Keroro, Tomosu Hinohara, and Myō Kaneami, all of which were originally manga-only characters. The opening to the series is "Keroro☆Popstar" (ケロロ☆ポップスター), performed byMayumi Gojo. The flash anime ended on September 6 of the same year, with a total of 23 episodes.
On April 1, 2024, it was announced through a video that the series would receive a new anime project produced byBandai Namco Pictures in commemoration of the anime's 20th anniversary. Many of the original cast are reprising their roles.[31]
Five full-length theatrical movies that were directed byJunichi Sato and produced by Sunrise were released:
An exclusive feature only available for limited time at specific Planetariums was released after the end of the show.
Many of the video games were only released inJapan, but there were others released inKorea.
