List of Sgt. Frog characters
The following is a list of various characters in the universe of the anime and manga series Sgt. Frog and related works.
Keroro Platoon
The Keroro Platoon 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 Gamma Planetary system. In the anime's English dub, the unit is referred to as the Advance Recon Mission Preparatory Invasion Terror Platoon. 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: Kumiko Watanabe ; Todd Haberkorn, Chris Cason, Andrea Kwan and Sarah Hauser, Vic MignognaSergeant Keroro is the leader of the Keroro Platoon, evidenced by the leadership star he wears on his belly. He has a green body and wears yellow, Imperial Japanese Army-style headgear with a red star in the middle, symbolizing that he is a leader. When the Keroro Platoon members happen to be caught in an explosion of some kind, they are seen with an afro. Keroro's black afro is most commonly seen.
Keroro used to be a good officer, but since his arrival to Earth and the subsequent loss of his Keroball, he has lost most of his interest in the invasion, preferring to spend his time making Gundam models, watching anime, or reading manga. Keroro has lived with the Hinata family in their house since arriving to Earth and often does their house chores.
Although Keroro is seen as weak and lazy by nature since he started living with the Hinatas, he is actually the most powerful and dangerous member of the platoon, becoming severely weakened due to Earth's atmosphere having significantly less moisture than back on Keron. This lack of humidity apparently weakens all Keronians, though Keroro appears to be the only member of the platoon to be significantly affected by this.
Occasionally, specifically, when there is a lot of moisture in the air, Keroro reverts to his previous self, a cold and ruthless soldier with enhanced strength, speed, and the ability to shoot powerful energy blasts from his hands. Though moisture returns him to full power, being exposed to it for too long turns Keroro into a crazed lunatic, causing him to attack everyone and anything in sight. Keroro becomes virtually unstoppable in this state and can easily overpower anyone who tries to stop him, including the members of his platoon and even Natsumi. This usually ends with a Nyororo, a creature that ventures throughout space that seeks out high moisture levels to feed itself, sucking off all of Keroro's moisture.
Keroro is carefree, ignorant, greedy, selfish, vengeful, unlucky, egotistical, smug, and cowardly, with a short attention span for anything not related to Gundam models. However, he occasionally displays bouts of unselfishness and bravery.
He misspends the invasion budget on models, and he always leaves the paperwork for their bosses back in Keron for the last possible moment, often punished for it. The son of an infamous war hero, the Demon Sergeant, Keroro, spent his childhood being raised by his father and was often punished for acting girly or lazy. Keroro's rise through the ranks was partially due to his father's influence within the military, allowing Keroro to do whatever job he wanted. He is childhood friends with platoon members Giroro and Dororo and is responsible for most of the latter's traumas. In some of the movies and other episodes, it is shown that he's good at convincing people.
Keroro's invasion plans often hide personal goals like getting back at Natsumi, raise or to improve his Gundam collection, or even preventing the Earth from being destroyed or conquered by other alien species. Even when they do not, they are often harebrained ideas without a chance of success. His plans also consist of how to distract humans while Keroro invades the Earth. He's raising money plans usually follow the same pattern and often involve Momoka hiring them for some crazy goal of her own. The few strategies that have a chance of success usually fail due to setbacks, Fuyuki's friendship appeals, or because another character points out that if Earth is destroyed, it would mean no more Gundam models.
Giroro
Voiced by: Jouji Nakata, Akiko Hiramatsu ; Christopher Sabat, Scott EvansCorporal Giroro 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. 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." 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 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. 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
Voiced by: Etsuko Kozakura ; Brina PalenciaPrivate Second Class Tamama is ranked Private Second Class in the Keron Army's Keroro Platoon. He is the newest member in the planetary invasion troop and the youngest, still having his tadpole tail and white face. Tamama has a dark blue body with yellow headgear and big round eyes. He wears a green and yellow mark on his head and belly, which matches the Shoshinsha mark that new drivers in Japan must display their cars for one year after obtaining their licenses. His Afro is a reddish-brown.
While usually seen as cute, gentle and cheerful due to his youthful appearance, Tamama becomes an insane, raving maniac when feeling overly excited, angry, or jealous. Tamama is prone to fits of jealousy, usually towards anyone who gets near Keroro, especially Angol Mois, whom he frequently refers to as "that woman" or "this woman." These negative feelings power his energy beam.
Tamama idolizes and has strong feelings towards Keroro, though the latter seems unaware of them. He is usually the first to support Keroro and his plans, no matter how ridiculous they can be. Though he is loyal to Keroro, Tamama's loyalty to him has become shaken when Keroro becomes emotionally abusive or overly lazy, having abandoned his commander on more than one occasion.
Tamama is very close friends with Momoka due to their similar personalities and lives with her in the Nishizawa Estate, much to his Platoon's jealousy. While living with Momoka, Tamama openly enjoys luxury and is very knowledgeable of Momoka's family wealth because of it. Though they got off on the wrong foot, both Tamama and Momoka are very loyal to one another to the point where Tamama will openly go against Keroro if the laters plans interfere with Momoka's plans to win Fuyuki's heart.
He hates Mois because of Keroro's feelings and trains hard until he defeats her and gains Keroro's affection. However, sometimes he is ashamed of his evilness when faced with Mois's pure heart. He relies on pure energy in battle, shooting his powerful attack, Tamama Impact, a yellow energy beam from his mouth. He's often seen training, usually beating up a piece of wood with a sloppy drawing of Mois.
Tamama loves snacks and sweets; living with the ultra-rich Momoka means he has as many as he wants.
