After crash landing on Pekopon, Zeroro was rescued by kunoichi Koyuki Azumaya (in the anime, he was rescued by Koyuki and Zeroyasha). Wishing to follow the way of the ninja, Zeroro changed his name to Dororo, after the forest where he was rescued. He spends most of his time training, reading, or spying on the actions of Keroro Platoon and others. Dororo is often forgotten by the rest of Keroro Platoon, causing his psychological trauma switch to turn on, making him sit in a corner and cry. Also, Dororo will not participate in plans that are potentially harmful to people's feelings or well being, the nature, etc.

A blue Keronian. Throughout his childhood, Zeroro wore a medical mask. The ears of his white hat were shrouds. His symbol is a red shuriken. Before when he was an assassin, he wore a gas mask. As the ninja Dororo, he dons a ninja mask and sheath for his sword strapped to his back. In dire situations Dororo can go into his full battle form, going through a transformation sequence inspired directly by Yoroiden Samurai Troopers, with two full-length swords across his back, and his usual assassin headgear traded for a ninja-style headgear with a metal headband.






As a child, Zeroro's hobby was gardening. Currently, he trains his physical swiftness and mental swiftness through meditation.

Zeroro was part of a large, wealthy family. He was friends with Keroro and Giroro, as well as Pururu later on. Though, he was often exploited by Keroro for dangerous tasks. Throughout their friendship, Keroro has broken Zeroro's beloved music box, used his stamp collection, wrote in his novels, etc. His friendship with Keroro was strained, as opposed to his with Giroro.

Zeroro graduated from the Keron Military Academy under the rank of Lance Corporal. After serving alongside Zoruru in an elite assassin squad, under the command of Captain Jirara, he was assigned as the assassin of the Keroro Platoon alongside Keroro, Giroro, Tamama and Kururu. They were given the mission to conquer Pekopon (Earth).

On Pekopon Zeroro was caught in a bear trap, abandoned by his teammates until he was saved and adopted by the kunoichi Koyuki Azumaya. She taught him the the ways of the ninja and after renaming himself Dororo, he rejoins the Keroro Platoon.
