Keroro Platoon
The is led by Sergeant Keroro. While most platoons contain thirty or forty soldiers, the Keroro Platoon only has a meager five. Its full name is the . In the anime's English dub, the unit is referred to as the Advance Recon Mission Preparatory Invasion Terror Platoon (A.R.M.P.I.T.). Keroro refers to the acronym as being "unfortunate." The initial operation of the Keroro Platoon was to stealthily survey Earth and relay information to the awaiting Keron Invasion Army. The five members were dispatched throughout Greater Tokyo and the surrounding areas to assess Earth's weakness and prepare for a total military takeover. Having infiltrated the Hinata house, Sergeant Keroro concealed himself in one of the bedrooms, but was accidentally discovered by the Hinata children, a pair of middle-school siblings. Shocked by their ability to see him, he was overpowered, captured, and temporarily stripped of his weapon, the Kero Ball. With Keroro coming into direct contact with the Earthlings, the invading army lost their surprise element, deemed the campaign compromised, and immediately started withdrawal procedures from Earth's orbit. Abandoned by the army and without his platoon's support, Keroro must unite his scattered soldiers, survive his prisoner of war manual labor, and outwit his captors. He is eventually connected with his platoon and subsequently given revised orders to continue the invasion campaign but by themselves. They must now fulfill their new mission, protect their human friends, their home base, and the Earth from other alien invaders. The platoon's hierarchy in military rank is similar to the Army ranks of the Japanese Empire during World War II and have based certain weapons, equipment, and terms after the Imperial Japanese Military, but remains faithful to the perception of the alien invader with higher technological achievements.Keroro

Voiced by: Jouji Nakata (Japanese), Akiko Hiramatsu (Japanese, child); Christopher Sabat (English, Funimation dub), Scott Evans (English, Animax Asia) is the Platoon's highly aggressive weapons expert. His body is dark red, while his headgear is dark maroon with a skull in the middle. He is the only member of the platoon who doesn't wear a symbol on his belly. Instead, he wears a belt with a rectangular buckle diagonally across his body. However, when he was a tadpole, he had a skull symbol on his belly. His Afro, which is rarely seen, is blond. Giroro is the only member of the platoon who takes the invasion of Earth seriously and is often frustrated by the lack of progress made towards accomplishing this mission. Due to Keroro's negligence in his duties as commanding officer, Giriro often acts as the disciplinarian in the platoon, keeping Keroro from ignoring his duties when the later forgets to submit his invasion reports to HQ or is caught spending their invasion budget on schemes that often put them in the red. Despite this, he will follow Keroro's orders, whether or not they make sense as he still holds respect for the chain of command. Giroro once had respect for Keroro as an officer before their mission to Earth and, at one point, attempted to restore Keroro to his former self. However, he soon came to regret it as Keroro had become too powerful for anyone to control. Though Kururu outranks him, Giroro acts as the de facto second in command after Keroro due to Kururu's volatile personality and laziness. Giroro had displayed outstanding leadership skills at times of crisis and has taken charge of the platoon on more than one occasion when the situation called for it, mostly on combat missions. Giroro is in love with Natsumi Hinata, something everyone but Natsumi seems to know since she defeated all his traps he set when he arrived at the Hinata house. He attacks anyone who seeks to harm her, even his platoon members. Giroro views Mutsumi Saburo as a robust romantic rival and will do whatever it takes to keep him from getting close to Natsumi even though she is in love with Saburo.'' Keroro Gunso'' manga volume 7 chapter 57 Despite being the most dedicated to the invasion of Earth, Giroro's romantic obsession with Natsumi has caused him to abandon his duties on more than one occasion which often end up with Giroro unintentionally botching Keroro's plans of the invasion when they put Natsumi in danger. Ever since his first encounter with the Hinatas, Giroro has been living in a tent in their backyard, where he roasts sweet potatoes he sometimes shares with Natsumi and obsessively cleans his weapons. The buckle of his belt hides his treasure, a photo of Natsumi. He shares his tent with a whitish-pink female cat he rescued from the rain and named "Miss Furbottom."''Keroro Gunso'' manga volume 6 chapter 52 Unknown to him, Miss Furbottom is in love with Giroro. Giroro has a short temper. He is often irritated by the laid-back and unfocused attitude towards the invasion of the other members of the Platoon, specially Keroro. He appears to be gruff, but he is an honorable frog with a good heart. He lacks any other hobby apart from his weapons. He is terrified of ghosts''Keroro Gunso'' season 4 episode 178 "Momoka Gōsuto Hinataka no Maboroshi de Arimasu" and sea cucumbers. He cannot drink more than a drop of alcohol without passing out. Despite being dedicated to the call of duty, Giroro is often used as comic relief. He is often crushed by something dropped from Natsumi's window or a falling object from space, usually containing an alien of some sort (or Karara). Other times he reluctantly volunteers himself to test Kururu's inventions at Keroro's request in the pursuit of money, which most times leave him injured. His romantic dilemma with Natsumi leaves him clumsy and blundering. His feelings toward her are often used by other characters to get him to agree to something, saying that she will like it.Tamama

His face and belly are black, and he battles using his two claws, sometimes a knife, which he also used when he defeated Koyuki. His bracelet is a new model of the Kero Ball. His best friend is Tomosu.Keroro Platoon Robot Double
The Keroro double platoon was created by the Keroro platoon to stand in for them while they took the day off. The double platoon is easily identifiable from the real one due to their differently shaped eyes and their somewhat curled feet (and, in Kururu's double case, a conic head). Still, Fuyuki and Natsumi were unable to notice the difference. However, they were left in invasion mode and tried to invade Earth for real before the real platoon stopped them. The platoon took the robots off again to do their homework, apparently limited by Kururu. But the platoon changed the mode to "do whatever you want" and took their obsessions to the extreme. They escaped to space and committed several felonies. Garuru's platoon was charged with stopped them but mistook them for the real Keroro platoon. The Garuru platoon defeated them, but they didn't realize they were robots.Garuru Platoon

Voiced by: Kappei Yamaguchi (Japanese) is the newest member of the Garuru Platoon who, like Kururu, is the team's intelligence officer and hacker. He captured the allies of the Keroro Platoon until Dororo's deathblow damaged the computers. According to Kururu, Tororo was his rival back in Planet Keron because of his desire to prove to others of his higher intelligence and to put Kururu down. Because of Tororo losing to Kururu several times, the young, twisted, and mad genius attempted attacks upon him, though he could never gain his desired victory. He later destroyed the entire Keroro Platoon Double. He then visited the real platoon in un-wanted honor. He usually laughs like Kururu.Zoruru

She has an energetic, down-to-earth, somewhat strict, and stubborn personality but is also nonviolent and mature, unlike most of the series's major characters. She graduated from the Keron Military Academy simultaneously with her childhood friends Keroro, Giroro, and Dororo. Pururu is sometimes referred to as Obaa-chan (old lady), making her go into small questioning fits of self-worth — despite her still having a tail. In the anime series, she later comes to stay on Earth to take care of Keroro's Platoon's health.Shurara Corps
The is a platoon of villainous Keronians. Their mission is to study the Keroro Platoon to judge when it is right to destroy them and steal the Keron star from Keroro. The Shurara Corps consists of the leader, Shurara, and nine subordinate members: Putata, Mekeke, Giruru, Dokuku, Kagege, Nuii, Gyororo, Robobo, and Yukiko.Shurara/Shirara

Unlike most Keronians, he has two body colors, purple and green. His symbol is a blue circle with squares on the sides and three small black rectangles pointing upwards. When he was young, he was a friend of Pururu, who was kind to him when he was hurt and put a star-shaped plaster on him. Due to this, he has a crush on Pururu. However, Keroro ripped the plaster off him. Pururu punished him, but Shirara was upset and vowed revenge. When he found a special gold and silver helmet called the Keromet, he put it on and was powered up. He changed his name to Shurara, formed the Shurara Corps, and decided to get Keroro's Keron Star. The helmet, though, was a planet eater, eventually expanding to huge sizes and absorbing Sharara, which caused Shurara to destroy it. After this, he became Shirara again and returned to Keron with Pururu.Putata
Voiced by: Kentaro Tone (Japanese) is a skilled artist working for the Shurara Corps, using the title of . Putata is a naturally yellow Keronian, though he has painted spots on his body, like around his left eye, where he is orange. Putata's symbol on his stomach and forehead is in the shape of a light green shuriken. His paintbrush and cap-like helmet with blue-tipped bolts on top are made out of mostly silver-colored metal. Putata's paintbrush is also a weapon that enables him to bring his paintings to life, though it has a limited amount of usable ink. It can transform into a Nyororo paintbrush that Putata uses to suck Keronians up and use the liquid as ingredients for ink. Keroro destroyed the paintbrush by holding some hot curry as he was sucked. In his introduction, Putata was seen vandalizing the residence and property of the Hinata family. The Keroro Platoon, by that time, did not know that he was a part of the Shurara Corps. Putata is the most energetic, lively, and vivid of the Shurara Corps. He is rarely moved to tears. Putata is very agile, which allows him to paint quickly.Mekeke

His puppet has large, blond sideburns, a crossed eyepatch, eye cross, four arms equipped with blades, and a puppeteer cross. Mekeke has amazing stealth and ability, though his puppet strings are easily broken. His puppet uses its puppeteer cross to levitate. This is a parody of Kankuro and Sasori's Crow from '' Naruto''. When fully exposed to non-solid substances, his invisibility is cancelled out.Giruru

After she is discovered, she is taken into the Hinata Household, where she loves and treats Nuii like a regular doll. Under the instruction of her superior, Gyororo, Nuii starts turning the Keroro Platoon and Fuyuki into dolls. When Gyororo urges Nuii to turn Natsumi into a doll, the memories of the time she and Natsumi had spent together make her hesitate and turn on Gyororo. Nuii can hold Gyororo still long enough for Keroro to capture him in a bubble. Afterward, Nuii turns everyone back to normal and flies back to Planet Keron, searching for her former owner.Gyororo

Keroro's father ("the Demon Sergeant")
Voiced by: Kenichi Ogata (Japanese); Greg Dulcie (English, Funimation dub) The father of Keroro and a legendary war hero in the Keronian military. He has an infamous reputation for violently invading and destroying planets. Once a high ranking Admiral, Keroro's father was demoted to the rank of Demon Sergeant after taking the fall for various war crimes on behalf of the Keronian Army even he was in fact guilty of all charges. His fearsome reputation, serious demeanor, and stern attitude often incite great fear into those around him. When Keroro's father informs him that he is coming for a visit, Keroro and the platoon work hard to cover up their lack of progress in invading Earth out of fear that the Demon Sergeant will indeed destroy the Earth should he find out. Even Natsumi, who shows little to no fear of other Keronians, is deeply afraid of Keroro's father and, at times, reluctantly agrees to Keroro's plans to prevent his father from destroying Earth at one point, even agreeing to pretend to be Keroro's fiancé. He is both admired and feared by his beloved son and was hard on him growing up. Part of why Keroro joined the military was to make his father proud of him. Despite his accomplishments, Keroro's father is still hard on him and constantly pushes him to become a man. During the Demon Sergeant's first visit to Earth, he arrived with news that he has arranged a marriage between Keroro and another Keronian in what seemed to be an attempt to get Keroro to settle down and become a man. However, Keroro was against this arrangement as married Keronian's were forbidden from playing with toys, meaning he would have to give up his Gundam models. This, however, turned out to be a ruse by the Demon Sergeant to get to spend time with his son, showing that he does care for him as a son. He frequently appears on vacation. He saved the Keroro Platoon by giving Viper a Parents Day message from his parents, revealing he was as weak and idiotic as his son. He revealed that Giroro's father, the Demon Sergeant's friend, was visiting and left with a photo of himself and Giroro's father. He has a Hitler Mustache and aDororo's Mother

When he first appears, he pretends to help Keroro with a plan involving insects. Still, when Dororo arrives at the end of the episode, he reveals that Mushishi is retired and devoted to his hobby to collect insects from around the galaxy, making the platoon realize that the old assassin has had them.''Keroro Gunso'' season 4 episode 181 "Mushishi Mushi no Idokoro o Sagas! de Arimasu" He carries a bug-catching net and a pouch as well as a green bucket on top of his head that he keeps bugs in.Kiruru.
was born from Mirara being sealed away with the real Kiruru, making him the Kiruru sealed away in the Invasion Timer. He is a tadpole version of his counterpart/father, Kiruru but with a dot over the X mark. He is an incomplete version of Kirara. Instead of absorbing the power of negative thoughts, this Kiruru absorbed the power of hesitation. He was released from the Invasion Timer and befriended theUrere
Voiced by: Toshihiko Seki (Japanese) is a highly ranked Keronian soldier who once assisted the Keroro Platoon in conquering Earth. It is purple. His helmet has headphones with a microphone attached. His symbol is an exclamation point, but the one on his chest is rendered upside-down, resembling a tie. He rarely blinks.Robobo Fukusocho
Robobo Fukusocho is a robot substitute for Kururu. He was made from silver metal. He has rectangle-shaped magnet feet and has crescent magnets for hands. His symbol is a black dot with golden tracings.Rirara

He went rogue and fled to Earth, seeking out Dororo for one final duel. He is outfitted in a top-to-toe black suit, with armored blade-arms like Zoruru, an assassin mouthpiece (minus the breathing valve in Dororo's old mouthpiece), and a mask with three glowing red eyes and a shuriken over his left eye. His symbol is a shuriken with diamond blades. Jirara's name is from Jiraiya.Sababa
settled on Earth during the golden age of Egypt, opening the possibility that the Great Pyramids were created through Keronian technology. Having evolved into a sand-based form after hundreds of years, Sababa has lost the ability to communicate in any coherent language, uttering 'sabarabara' at random, which leads Keroro to dub him Sababa. He wears an old and worn headgear, kohl around his eyes, and a pharaoh hook in place of his right hand. His symbol resembles two triangles end-to-end, the lower one twice as large as the upper, which is decorated with two eyes (a possible reference to the familiar eye-on-a-pyramid symbol on the US dollar bill.) The name Sababa comes from ''sabaku'', meaning desert.Meruru
is a member of Keron's official postal service, who comes to Earth to deliver a message for Keroro, which he tries to avoid receiving, thinking that it is a message from headquarters (but turns out to be a letter from Shipepe, Keroro, Giroro and Dororo's long time friend). Meruru is dedicated to her job to the point that she maneuvers her way around all of the platoon's attempts to detain her, including cloaking devices, guns loaded with capsules of sticky gunk, evasive driving, and Tamama's farting (which Meruru isn't slightly bothered by and possibly likes). Meruru's symbol is an envelope.Kikaka
is an artificially made Keronian which befriended Zeroro/Dororo and soon after Keroro, Giroro & Pururu during their childhood and having a few adventures with them, such as scaring away some bullies. The bullies then mistake Kikaka for the escaped biotech weapon that the army's been searching for and plan to turn him in until the real weapon (a more modern Kiruru) shows itself and Kikaka wards it off.

His eyes are colored blood red with black-lined rings around his pupil, his symbol is a black star (hence his name), and it is upside down, as opposed to Shin Keroro's Keron Star.Nobibi
Voiced by: Hidekatsu Shibata (Japanese) is Kiko Katoyama's Keronian friend. He is spoiled and quick-tempered towards the Keroro Platoon, but playful and kind towards Kiko. Nobili has a younger sister, Hanna.Hanana

These partners are all teenagers (who in the anime attend Kissho Gakuen, a middle school in Tokyo) and have their own web of correlations.Hinata Family
Fuyuki Hinata
Voiced by: Tomoko Kawakami (Japanese, first voice), Houko Kuwashima (Japanese, second voice); Leah Clark (English, Funimation dub), Candice Moore (English, Animax Asia dub) 12-year-old Fuyuki is intelligent on the surface, but is an oddity even within that scope, as his main interest is in the 'occult' — a term that comprises everything from the best-known international mysteries (Natsumi Hinata
Voiced by: Chiwa Saito (Japanese); Cherami Leigh (English, Funimation dub) 13-year-old Natsumi is the powerful older sister of Fuyuki and the one in charge of the Hinata house when their mother is not home. A minor celebrity in her own school, she often gets pleas of help from classmates like Yayoi and Satsuki (below), due to her unparalleled physical skills. Feisty and genial, Natsumi is equally capable as a friend, a fighter, and a loving family member. She is very strict on Keroro and always doubts of his intentions, physically abusing him on several occasions (as well as treating him as a house slave), and never calls him by name, only snapping ''"Boke gaeru"'' ("stupid frog") at him whenever she has to. Inversely, Natsumi's infatuation with Saburo proves to be one of her few weakness on several occasions and mostly end up with her humiliating herself in front of him. Despite her general dislike of Keroro, Natsumi comes to care for him over time and comes to see him as a member of the Hinata family. Natsumi has a general dislike for Keronians (especially Keroro) due to their tendency to cause trouble and destruction wherever they go. Since Keroro tried to enslave them with the Keroball during their first meeting, Natsumi is almost always on high alert when it comes to Keroro and his men and is usually the first one to confront them whenever they try to take over the world. Given her high athletic ability and martial arts training, Natsumi shows little to no fear when facing the Keronians and is often the victor in their battles. The only Keronian Natsumi has shown genuine fear of is Keroro's father, the Demon Sergeant, due to his reputation of destroying planets when he is angry. Her fear of the Demon Sergeant has caused her to reluctantly go along with Keroro's plans to prevent his father from destroying the Earth. Natsumi is often the unwilling victim in many of Keroro's schemes due to her constant abuse of him, though she typically gets back at him by beating him up. Ironically she sometimes blackmails him into including her, Fuyuki, occasionally their mother and other friends in his plans, mostly when they involve travelling to exotic locations like the beach or outer space. Unlike her brother, Natsumi is highly sensitive spiritually, feeling an "oppression" when ghosts are near. Natsumi's toughness and tomboy personality have caused most of the girls in her school to fall in love with her, in some cases stalking her in cooperative packs and forcing her brother to deliver presents to her on Valentine's Day. So far though only the new ninja girl Koyuki has made any direct moves on her. To date Natsumi seems unaware or in denial of her effect on other girls. Natsumi's Keronian partner is Giroro, but theirs is the most unofficial as far as relationships go. While they relate to each other almost subliminally (from hot tempers and combative tendencies to a love for roasting sweet potatoes) and are close personally, Natsumi has no idea that Giroro has been infatuated with her since the day she first bested him in strategy and combat: an incident that involved her busting past his boobytraps armed with a leek and taking him out with a bookbag to the head. In fact it is Keroro that Natsumi is more strongly connected to — their petty rivalries sit high above a deep, underlying current of mutual respect and concern that runs both ways. It is shown that she separates Giroro from the other frogs, as she calls the ARMPIT Platoon 'Giroro and the stupid frogs/the others'. In episode 269, she hugs and cries Giroro when he came back alive from Natsumi's large intestine, while she did not when in one of the earlier episodes, Keroro came back alive from banishing forever, instead she only shed some tears.Nina
Voiced by: Ayaka Saito (Japanese) A Humanoid Alien who came fromAki Hinata
Voiced by: Akiko Hiramatsu (Japanese); Jamie Marchi (English, Funimation dub), Candice Moore (English, Animax Asia dub) is the mother of Fuyuki and Natsumi Hinata and is the head of the family that Keroro lives with. Her exact age is unknown; however, she is believed to be around 35 years old. Beautiful, kind, and immensely strong, Aki first meets Keroro after he subdued her children in an attempt to take over their house. Although she swiftly stopped Keroro from taking over their home, Aki became fascinated by Keroro being an alien and allowed him to stay with them until he could reunite with his platoon. Whether it is supporting a family of three on her own, making late night runs to the printing press on her motorcycle, or kicking aliens around every few weeks, it is common belief (at least to the Keronians) that Hinata Aki is the strongest woman on Earth. Despite her fear of animals, she feels as though the Keroro Platoon is her own family (due entirely to them being shiny and possibly slimy, as opposed to the furry nature of most animals). As a chief manga editor/designer, she finds the aliens' lifestyle very interesting and often has spells of obsession over them. While Aki has no official Keronian partner (as none of the adults do), it is Kururu who has taken a special interest in her, to the extent of setting up a spy camera in her shower.

is Aki's husband and Fuyuki and Natsumi's father. He is never fully shown and is rarely mentioned in the anime. He is known to be constantly traveling the world, and it is unknown if he actually knows about the Keronians living in his house or about aliens at all. His own interest in mysteries around the world, like the Easter Island's Moais, seemed to inspire Fuyuki's occult obsession.Nishizawa Family

Baio trusts his daughter's happiness due to him living out of state, usually in a castle by a lake in Scotland. He tries to meet with his daughter, but he rarely accomplishes it. He is aware of the existence of the Keroro platoon. Flashbacks to his youth reveal him to be based on Ryu of '' Street Fighter'' fame. His older self looked liked Tony Stark from Marvel Comics ''Oka Nishizawa
Voiced by: Yoshiko Sakakibara (Japanese) is Momoka's mother and Baio's wife. She has amazing fighting skills. She encountered Baio as her finalist opponent during a martial arts tournament. After the battle, the two fell in love, married, and had Momoka. When Momoka matured, Ōka had left the mansion to Momoka. She returns during Mother's Day and her abilities were tested. In a later episode, Oka was capable of defeating Giroro and Dororo plus Kururu's battery of missiles unarmed, and only her husband proved to be a strong enough rival for her. Much like her daughter, Ōka has both a violent and gentle personality. Her gentle personality occurs when she is treated with love and she loses her violent outlook. Oka's design is modelled after Chun Li of '' Street fighter'' fame, but she always shows up first in a thick brown cloak over her entire body, tossing aside anything that gets in her way, reminiscent of Kenshiro's return to civilisation in '' Fist of the North Star''.Mutsumi Houjou

Voiced by: Mamiko Noto (Japanese); Laura Bailey (English, Funimation dub) is a doppelgänger of Mois/cousin of the dreams, martial arts champion. She was turned into a "bad" girl when she got in a fight to protect her friends. Asami was committing crimes and Tamama was quick to say that it was Mois. So Mois could confront Asami, Kururu made a projection device that made every one look like Asami. Angol Mois based her human form on Asami. Mois was told by her father to find the most powerful Pekoponian and make herself look like that Pekoponian. Mois did, and so now she can transform and look like Asami.Kiko Katoyama
Voiced by:The Angol
The Angols are a group of humanoid alien race whose main purpose is to destroy a planet as their tradition to their race.Angol Mois
Voiced by: Mamiko Noto (Japanese); Carrie Savage (English, Funimation dub) "July 1999. The Queen of Terror descends from the sky and Angolmois awakens." Angol Mois is the "Queen of Terror", who is ditzy and insecure as a result of her impact from space. She was sent to planet Earth to arrive in July 1999 for Earth's destruction, as predicted by Nostradamus, under orders from her father. She states that during her first appearance she told Nostradamus to deliver a message to the humans warning them of her arrival. In the anime broadcast she arrives 500 years too early and takes a nap in orbit, waking up several years too late (as the anime was originally broadcast after 1999).''Keroro Gunso'' Season 1, episode 7 "Moa Hajimete no Chikyū Hakai" In the manga, she lands near Fuyuki, while in the anime, she lands on Giroro's tent (and on top of Giroro, who was inside). In both, she is taken into the Hinatas' home, where she is nursed back to health by Natsumi. When she wakes up, she reveals her true form and starts to destroy the Earth, until Keroro, who arrives later, is persuaded by Fuyuki (who reminds him that if Mois destroys Earth, there would be no more Gundam models) to stop Mois. Although the Lord of Terror, she is anything but terrifying. She's sweet, clumsy, and peppy, with no malice whatsoever but can be scary when she gets her Lucifer Spear out. The Lucifer Spear, which she only can use while in her true form, is a terrible weapon that could, at its fullest power, completely destroy Earth. She usually uses only an infinitesimal part of its power to destroy things; her most commonly used technique, "Destruction: One Millionth", is likened to a localized meteor impact. The Lucifer Spear doubles as a cell phone, which Mois keeps in her pocket. The weakness of the Angol is a mineral called Angolnite, that neutralizes her powers. She keeps a crystal of Angolnite hidden in her room just in case.''Keroro Gunso'' Manga Vol 14, chapter 117 She is close friends with Keroro, since the sergeant used to play with her when she was a child. She calls Keroro ''oji-sama'' (roughly, "uncle"). She is in love with him and dreams of being his girlfriend, though Keroro seems oblivious. Tamama considers her his rival and often competes with her for Keroro's attention (and affection), though most of the time Mois don't ever realizes she's competing. Often, her pure heart puts Tamama to shame without even realizing it — an unconscious weapon that works against the cynical Kururu. Her main goal is to make Keroro happy, something Keroro takes sometimes advantage of to make her do his cleaning work in his place. She also works as part of the platoon as communication's officer and overall helper. She lives in a room at the platoon's underground base.''Keroro Gunso'' Season 1 episode 16 "Moa Ura Moa Kōrin!? de Arimasu" In her true Angol form, she is a pale gray-haired, brown-eyed girl who wears a purple, yellow and white costume. However, to blend in with the Earth people, Mois transforms into a tanned, bleached-blonde teenager ( kogal) who is always seen in a school uniform and loose socks. She got her Earth look from when she first arrived, not long before she met the Hinatas. In the manga, her father had encouraged her to see only herself as important as this frame of mind was needed to become an effective planet destroyer. Thus, she chose the form of a Japanese school girl she saw ending a friendship with another girl for her own benefit. In the anime, she chose the form of a girl who was fighting for her friends, thus becoming her "inspiration." Her transformation sequences, stylized costume, and related accessories may make her a parody of the "magical girl" genre. As an added note, Mois's Pekopon-form wears a hairclip explicitly in the shape of the Science Patrol's meteor-mark in the anime (while Asami, the girl whose form/soul she "borrowed", has an Ultra Garrison-mark hairclip). Her name is frequently used in puns on the Japanese phrase ''moe-moe'', which usually refers to a cute girl who appeals to older members of the audience. In the English manga, her name is "Angol Moa". In the English anime, her lucifer spear is called "Hellmageddon", an amalgamation of the words "hell" and "armageddon" meaning doomsday.King of Terror

Voiced by: Juri Ihata (Japanese); Caitlin Glass (English, Funimation dub) Sumomo is a member of the Axolotl, a race based on newts in the same way the Keronians are based on frogs. In the manga, a girl finds Sumomo. Sumomo immediatally falls in love with Fuyuki Hinata and tries to "kiss" him by wrapping her tongue around him, because she does not know Earth's customs. The girl's father finds Sumomo, and like Keroro, was converted into a comic book character. In the anime, Sumomo is an immensely popular pop singer known throughout most of the galaxy. She first appears after she crash lands on Earth and is found sleeping on top of Fuyuki in his bed. Though initially claiming that she is there to sing for Keroro and his men, she eventually admits that she came to Earth to briefly get away from her fame, though she eventually leaves after realizing she loves being a known celebrity. Sumomo returns to Earth occasionally to seeks the frogs help in her celebrity activities. As Keroro is one of her biggest fans, he frequently puts his men to work doing whatever she needs or asks, such as setting up a concert or building a replica body of Natsumi for a reality prank show. Sumomo has the ability to change her form into a hot chick of four hundred alien species including human. Like the comic book, she does not know Earth's customs, butAlisa Southerncross

Nyororos are the only species capable of neutralizing Keroro when he is overly exposed to moisture and becomes to powerful to control or stop. When Keroro is exposed to too much moisture, the Nyororos become drawn to Keroro and are usually able to find and suck the moisture out of him. They are even able to track him from very far distances extending into space. However, some aliens use Nyororo as a reducing-weight tool (Putata of the Shurara Corps and Kururu are known to rear their own Nyororo for their own purposes).Nyororo Ω

Voiced by: Nobuo Tobita (Japanese); Charles Campbell, Jerry Jewell, Chris Patton, Austin Tindle, Eric Vale (English, Funimation dub) :Viper is the name claimed by all members of the immediate and extended Viper family and friends. Each Viper character, upon entering the scene, will explain his or her relationship to the previous Viper. The first Viper fought the Keroro Platoon per the age old "snake versus frog" battle and thought it was his right to abuse the weaker Keronian. After all, snakes often ate frogs as part of their diet. However, with his defeat, each subsequent Viper has been on a vendetta against the Keroro Platoon. The exception is Viper Mother, who on Mother's Day, was only traveling to earth to visit her son, Viper. Each member of the Viper Family is outfitted with a red jumpsuit, black belt, and right hand blaster. Variations of Viper and the Viper family can be seen in the Viper Wedding, Episode 74 "Surprising — Keroro Special Version, gero gero 30 minutes, 15 stories". Their appearances(red jumpsuit, hand blaster, and cigarette) is parody of Cobra.Viper (original)
The first Viper who fights the Keroro Platoon because of a war between the Keronians and the Vipers, and was defeated by a technique used by Dororo. He reappears in Episode 121, where he appears as a cyborg who takes revenge on Dororo, but ends up capturing Chiroro and hides in Alien Street from the Space Police and the Keroro Platoon. To keep himself from being spotted, he disguises himself as a chef in a ramen stand. When Keroro disguises himself as Viper and captures Karara in an effort to earn money, Viper takes off his disguise and attempts to defeat the fake Viper, proving that he does have some good in him. Viper's cyborg appearance is very reminiscent of Freeza, of Dragonball Z fame, when he became Mecha Freeza. His left half has been completely demolished and replaced with mechanical parts, his left eye is green and has a yellow scope as its pupil, a black tube appears on his head and leads to the back of his head, and the buster arm he had before has now been replaced with a mechanical claw. He has a son that was taken away by his ex-wife who he taught a technique on how to make the Tokyo Tower out of cherry stems.Cool Big Brother Viper

Voiced by: Daiki Nakamura (Japanese) Created by Keroro upon learning that Natsumi was afraid of slugs, Wettle King (ウェットルキング, Wettoru Kingu) is a common slug evolved by Kururu into a humanoid being who resembles a green Ultraman with tiny eyes and feelers on his head. Though he has 1000 times the strength of a normal slug, he was still quite weak, but his attacks worked against Natsumi because she was so much revolted by his viscosity. Fuyuki, however, was able to defeat him with a finger. Unless he's in an ambiance with very high humidity, he can only fight for 4 minutes and 44 seconds before he has to recharge himself with water. Despite Keroro's intentions, Wettle King's spirit of righteousness forbade him from harming Natsumi, and he flew off into deep space in the end to find someplace where he could be useful, until his powers were needed once again.''Keroro Gunso'' season 3 episode 113a "Keroro Tatakae Bokura no Wettoru Kingu de Arimasu" and 113b "Natsumi Kaettekita Wettoru Kingu de Arimasu". In episode 215, Wettle King returns with the additional ability to disguise himself as Tohru Uetsu, a motorcycle-riding, smooth-talking (and incredibly clumsy) photojournalist, along with playing a trumpet during his entrance scene, he is reminiscent of Hayato Icimonji, the second ''Wettle King Clones

He has a red X on his forehead, much like the placement of Keronian emblems on their hats. He attacks by flying through the air and giving people an X mark on their body. This allows them to telepathically communicate and give more Xs, but Kiruru powers himself using their negative emotions and the victims eventually only think about negative thoughts. Then, once he obtains enough power, he transforms into a more powerful form, which looks like a large beast. In this form he has no legs, instead he has a long, thick tail and moves around with his two hands. This form and the next are impervious to damage and generate a strong paperlike substance from its limbs to cover up large expanses of land. After collecting even more negative energy, Kiruru transforms into a tower and begins cloning his first form.
