List of Sgt. Frog characters
Its full name is the Gamma Planetary System, the 58th Planet, Space Invasion Army Special Tactics Platoon (ガマ星雲 第58番惑星 宇宙侵攻軍特殊先行工作部隊, Gama Seiun Dai Gojūhachiban Wakusei Uchū Shinkōgun Tokushu Senkō Kōsaku Butai).
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.
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.
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.
Keroro is carefree, ignorant, greedy, selfish, vengeful, unlucky, egotistical, smug, and cowardly (especially against Natsumi), with a short attention span for anything not related to Gundam models.
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.
This alliance included: Toriri (bird-like), Saruru (monkey-like), Inunu (dog-like), Aruru (a nurse), Mukaka, Tsunene (fox-like), Tanunu (tanuki-like), Honolulu (a golem), and Garnier (a sand granite Keronian).
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.
The two do share a natural curiosity (Fuyuki is drawn towards the mysteries of the world, while Keroro is mystified by things most humans consider commonplace), as well as the strongest friendship of the five Keronian/human child pairs.
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.
[5] 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.
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.
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.
While being a well-connected heiress who lives in an expansive mansion, Momoka views her extravagant lifestyle as completely commonplace and acts in a refined and timid manner for most of the time.
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.
Voiced by: Megumi Toyoguchi (Japanese); Tia Ballard (English, Funimation dub)[11] Melody Honey (メロディー・ハニー, Merodī Hanī) is a famous pop star from America who appears in the most unlikely places.
Voiced by: Hiro Shimono (Japanese); Mike McFarland (English, Funimation dub)[11] Masayoshi Yoshiokadaira is one of the hundreds of faceless black ops agents in the Nishizawa Peach Group.
Only two things distinguish Masayoshi Yoshiokadaira from them: his awkwardly long name, and his tendency to be thrust into prominent roles during Momoka's get-close-to-Fuyuki plans, such as 'eloping' with her in episode 98.
Voiced by: Mamiko Noto (Japanese); Laura Bailey (English, Funimation dub) Angol Asami (麻美) is a doppelgänger of Mois/cousin of the dreams, martial arts champion.
Voiced by: Tomoko Kaneda (Japanese); Leah Clark (English, Funimation dub)[11] Kogoro's sweet natured younger sister who wears rabbit ears.
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.
Voiced by: Nobuo Tobita (Japanese); Charles Campbell, Jerry Jewell, Chris Patton, Austin Tindle, Eric Vale (English, Funimation dub)[11] Each member of the Viper Family is outfitted with a red jumpsuit, black belt, and right hand blaster.
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.
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.
[32] 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 Kamen Rider and his costume was a parody to Ichiro of Kikaider 01[citation needed].
Voiced by: Asuka Tanii (Japanese); Maxey Whitehead (English, Funimation dub)[11] One of the Space Policewomen, she always shows up just before the Keroro Platoon can successfully conquered Earth every time.
With a head shaped like a lava lamp and a two-colored skin tone split down the middle, these members of the Events Alien race are commonly seen in charge of galactic television stations.
Left behind in their undersea home by an ancient Maron alien army after an unsuccessful invasion, Meru and Maru appear to be sea lizard-based in the same way the Keronians are based on frogs.
With the corrupted Mer Ball forever out of the wrong hands, Meru and Maru ultimately fall in love and wish their friends farewell as they start a new life on Maron as prince and princess.
After a tough battle with Keroro and his platoon, he manages to steal Kururu's knowledge, Tamama's power, Dororo's skills and Giroro's determination by swallowing them, absorbing their energy and then spitting them out.
