Keroro Platoon
Main article: Keroro Platoon
Sergeant Keroro is the manipulative anti-hero and title character, who spends most of his time making Gundam models and doing chores for the Hinata Family. Born Dec 9th, he and the platoon were sent to Earth to conquer it but have had little luck so far in making any progress towards that goal. Despite being the leader of his platoon he does little to help and lets his subordinates do all the work.
Serving Keroro without question is Private Second Class Tamama who adores Keroro and is portrayed as the cute and lovely character of the show. Tamama has a split personality, much like the human he stays with, Momoka Nishizawa, and will revert from being cute and adorable to a violent berserker at something as small as a normal housefly. He is also jealous of anyone who gets near the Sergeant, especially the planet destroyer Angol Mois who also adores Keroro. Tamama is often seen gritting his teeth and grumbling あんの女! (anno onna! That woman!?) when Angol Mois gets close to, or helps Keroro in any way . Private Second Class Tamama's signature moves are his tamama impact and 嫉妬玉 (Shittodama Jealousy ball). Tamama loves snacks and sweets.
Perhaps the only sane individual in the platoon is Corporal Giroro, the group's gunman who has deadly accuracy and is exceptionally good at cooking sweet potatoes. He is often frustrated with Keroro's laziness and is disgruntled by Keroro's indecisiveness with regards to the invasion. Giroro is in love with Natsumi, and this also gets in the way of the invasion. Keroro often gets Giroro involved in schemes he would likely not be involved in by using Giroro's affection for Natsumi to his advantage.
The platoon's intelligence officer and inventor, Sergeant Major Kururu, is gloomy, insidious, unpopular, and disliked by some, who see him as depressing and malevolent. He makes most of the platoon's inventions and in spite of his malevolent nature, none of his inventions have any permanent effect. Kururu loves Japanese curry and is often seen eating it, and has even been shown in one episode to bathe in it. Kururu has some signature speech patterns, like his weird laugh and the fact that he always gropes around on the ground saying めがね、めがね (megane, megane Glases, glases) when something happens to break them. Kururu is good friends with Saburo to whom he gave a pen that can cause the physical materialisation of anything that is drawn by it.
The fifth and final member is Lance Corporal Dororo, who follows the way of the ninja, after being rescued by Azumaya Koyuki from a trap he got caught in while he was separated from the rest of the platoon. Dororo, formerly known as Zeroro, has known Keroro and Giroro since their childhood. Dororo is often abused and mistreated by Keroro, but still follows Keroro's orders because of their friendship. Due to these childhood abuses however, Dororo often falls into a deep but temporary state of depression (called his "trauma switch") whenever he is reminded of something bad Keroro did to him during his childhood. Dororo is also often overlooked or forgotten by the others, also triggering his "trauma switch". Dororo, formerly Zeroro, graduated as the top of the Keron assassin squad, even though he used to be weak as a child, due to being constantly pushed to his limit by Keroro with the words 友達 (tomodachi Friend?) while they were children. Dororo's signature speech pattern is that of someone from the feudal era of Japan. His signature move is assassin magic with which he can assess the relevant details of
