The Froglike Creatures from the Planet Keron have come to invade.
The Keron Leader: The leader of all of Keron's forces. The Keron Leader is a mysterious man that nobody knows much about.
The Keroro Platoon:
Sergeant Keroro: The commanding officer of the Keroro Platoon, despite this, he is quite a lazy good-for-nothing character. He prefers building Gundam Models over invading and has virtually no battle skills, but he is quite formidable with a Vacuum Cleaner. He is highly receptive to humidity and will become one of the most destructive forces ever known if exposed to a high enough level of humidity, however, humidity also attracts Nyororo, the natural predator of the Keron race.
Corporal Giroro: The second in command of the Keroro Platoon and the greatest marksman in the entire Keron Army. He's a seasoned soldier with amazing CQC skills that have never been matched by anyone other than Natsumi Hinata. Unfortunately for Giroro, he isn't able to interact with normal society well because he only knows how to be a serious soldier.
Lance Corporal Zeroro(Dororo): The assassin member of the Keroro Platoon. When the platoon was invading Pekopon(Earth) Zeroro was separated from the platoon and became a defender of Earth and changed his name to Dororo. Childhood friends with Keroro and Giroro, Zeroro was put through so much torture that it made him almost invincible, unfortunately this led to such childhood trauma that Dororo often has some traumatic episodes. Dororo came with the keron army to help protect Earth from attack.
Sergeant Major Kururu: A genius and a jerk. Kururu is the informations officer for the Keroro Platoon, as well as the creator of the majority of the platoon's strange machines. He's got a shady personality, an annoying laugh, and does things just to make people mad.
Private Second Class Tamama: The basic combatant in the Keroro Platoon. Tamama has a split personality that swaps between an overly polite character that really only cares about himself and an extremely aggressive personality. Tamama is able to fire a powerful beam from his mouth called the "Tamama Impact". Tamama is in love with Keroro, but is silent about it.
Angol Mois: She normally appears to be a normal blonde Japanese girl, but is, in fact, an Angol capable of destroying an entire planet. Her bright personality counteracts Kururu and Tamama's dark personalities. She calls Keroro "Uncle" and is in love with him. Tamama despises Mois, seeing her as a rival in getting Keroro's affections.
