Keroro/Sgt.Frog

***Sgt. Frog*** (ケロロ軍曹 *Keroro Gunsō*?, lit. "Sergeant Keroro") is a manga series by Mine Yoshizaki. It was later serialized into an anime TV series directed by Junichi Sato.
 Both the anime and manga are comedies that follow the attempts of a
platoon of frog-like alien invaders to conquer Earth. Sergeant Keroro,
the titular character, is the leader of the platoon, but is at the mercy
 of a human family of three after he is captured while trying to hide in
 one of the family member's bedrooms. In both the manga and anime,
Keroro is forced to do meaningless chores and errands for the family
after his army abandons his platoon on Earth. The platoon has many
failed attempts at taking over Earth.

The series takes its comedy from a combination of wordplay
(particularly puns and homophones), physical humor, situational irony,
breaking of the fourth wall, and numerous pop culture references (especially to *Gundam*, *Kamen Rider*, *Super Sentai*, *Space Battleship Yamato*, *Dragon Ball*, *Neon Genesis Evangelion*
 and many others, although when broadcast and published in the United
States, they make references that American audiences would be familiar
with like *Ghostbusters* and *Men in Black*).[1]
 Various anime, games, manga, and other aspects of pop culture are
parodied/referenced throughout the series as a bonus to older viewers.
Both the manga and the anime are laden with pop-culture references, and
even in the same story the references often vary wildly. The anime does
not explicitly refer to Evangelion or other animations to which Bandai
does not hold the copyrights, but only recreates the "feel" of famous
scenes from these anime. The anime is much more detailed and direct in
its Gundam references, however, since its animation studio, Sunrise, is a
 subsidiary of Bandai who does hold the rights to the Gundam franchise.
Season 2 began on April 1, 2005, with episodes aired on Fridays instead
of Saturdays. With Season 4's debut on April 7, 2007, episodes aired on
Saturdays instead of Fridays. With Season 7's premiere on April 4, 2010
episodes aired on Sundays instead of Saturdays.

## Plot

The main plot of the story focuses on the steadily deteriorating
conditions of the Keroro Platoon, a group of five, frog-like aliens from
 Planet Keron of the Gamma Planetary System. The platoon’s mission is to
 invade and conquer Earth (known to the aliens as “Pekopon”), but fail
miserably at each attempt. Sergeant Keroro (or Keroro Gunso) although
being the leader of the platoon, is childish, incompetent, and would
rather spend his time indulging in his hobby of making plastic Gundam models
 than take over Earth. Aside from Keroro, there are four other members
of the Keroro Platoon: adorable but violent Private Second Class Tamama;
 bellicose yet tenderhearted Coporal 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
human is Natsumi Hinata, whom he falls in love with; Keroro's human is
Fuyuki Hinata, who considers the Sergeant his only true friend; Kululu's
 human is Mutsumi Saburo, who discovered him; Dororo's human is Koyuki, a
 fellow ninja; and Tamama's human is his equal in bipolar insanity,
Momoka Nishizawa. All are tied to the Hinatas in some way throughout the
 events in the anime and manga.

## Media

### Manga

*Sgt. Frog* is published in Japan by Kadokawa Shoten, serialized in the magazine *Shōnen Ace*, and was published in English by Tokyopop. The Keroro Gunsou manga began its monthly run in the weekly shōnen magazine, *Shōnen Ace*.
 The manga, first aimed at the older audience (teens/adults) from the
first to the seventh volume, was toned down after the Anime 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 the Sgt. 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. [2]

### Anime

The anime series started airing on TV Tokyo in 2004 and ended in 2011. The anime is produced by Sunrise, and has been aired on Animax, TV Tokyo, and TXN.
 Seven seasons have been created during it 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. ADV had previously announced they had acquired exclusive rights to an English dub of *Sgt. Frog*[3] (for $408,000[4]). However, on July 4, 2008, it was announced that rights to the English release were transferred to Funimation Entertainment.[5]

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."[6]
 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 by Tokyopop) for the US.[3]
 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.[7] ADV announced at Comic-Con International 2007
 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 by Vic Mignogna[8]),
 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 from Summit Entertainment (the company that worked with 4Kids Entertainment during the time they had Pokémon).
 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, while Nickelodeon
 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 to Funimation Entertainment through a deal with Sojitz.[5]

Funimation released a dubbed version of episode 12B as a test on YouTube to be reviewed by the viewers.[9]
 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, and Keron changed to
Frogulon. The frogs' names remained the same as the Japanese version,
though shortened by one syllable (e.g. Keroro changed to Kero, Tamama to
 Tama).[10] The test episode had mixed reviews by fans involving the voice acting, jokes, and name changes.

At Otakon 2009, the first five episodes of Sgt. 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 to Chuck 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 at Katsucon that they had licensed more episodes of Sgt. Frog.[11]

According to FUNimation, as of February 2013, Sgt. Frog is "now on hiatus".[12]

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 and Hulu. The 51 dubbed episodes later expired, although they were all later placed back on the portal and on Hulu.[13]
 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,[14]
 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,[15] Season 1 Part 2 was released on November 24, 2009, and contains episodes 14 through 26.[16] Season 2 Part 1 was released on January 26, 2010, containing episodes 27-39.[17] In addition, Season 2 Part 2 was released on March 30, 2010 containing episodes 40-51.[18] The first two boxsets were re-released into one Season 1 set on March 29, 2011.[19] The complete Season 2 set followed up on April 26, 2011.[20] Season 3 Part 1 was released to DVD by Funimation beginning on July 26, 2011, containing episodes 52-65.[21] Season 3 Part 2 was released to DVD on August 16, 2011 containing episodes 66-78.[22] A complete Season 3 boxset containing episodes 52-78 was released on November 13, 2012.[23]
 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 is Yoshiyuki Tomino.

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,[24] before the series was completely removed in April of the same year.

On January 7, 2014 it was announced that a new Flash anime television series entitled "Keroro" would premiere on Animax on March 22 of that year.[25]
 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 by Mayumi Gojo. The flash anime ended on September 6 of the same year, with a total of 23 episodes.

appearances in the movie of *Kaiketsu Zorori*. Keroro and Tamama have appearances in the OVA of *Lucky Star*,
 and Kagami spends almost all her money on a grip-claw game trying to

Kayamba and Cha-Cha.

subtitled version), Natsumi refers to Keroro as "Reptile" instead of
"Stupid Frog" and Mois refers to Keroro as "Cousin" rather than "Uncle".

 were generally the same (in pronunciation) as the Japanese names. It
has become one of the most largely known Japanese anime in Korea, along
with Crayon Shin-chan, Atashin'chi, and Death Note.
 It has many parodies to Korea in translation, with using famous Korean
Internet memes at the time, and in the ending song of the fourth season,
 "You could say, violently going?", all main 12 voice actors did over 8
parodies to numerous things, such as "This is the first time I wanted to
 punch a girl (Death Note)" and "Is this... 'youth'? (Gundam)".
