Dororo Robo MK-II

Lance Corporal Dororo (ドロロ兵長 Dororo heichō)
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.

Also, Dororo will not participate in plans that are potentially harmful to people's feelings or well being, the nature,
