Dororo (ドロロ), formerly known as Zeroro (ゼロロ), is a main character in the anime and manga series Keroro Gunso. He is of the rank Lance Corporal (兵長 Heichō)[RANKS] and he is a part of the Keroro Platoon. Although he used to be one of the best assassins in the Keron Army, he went native upon arrival on Pekopon and chose to become a ninja and protector of the planet.
Dororo spends most of his time training, meditating, reading, doing nature-related works, or spying on the actions of his Platoon and others. Dororo is often forgotten by the rest of Keroro Platoon, causing his 'trauma switch' to turn on (his biggest fear [see Episode 123]). This usually leads to him sitting in a corner to cry, quietly reeling off many bad experiences to himself. This only occurs in the anime.
There are two people that do not regularly forget about Dororo: Koyuki, one of his best friends, and (ironically) Zoruru, the psychopathic maniac who has fixated on Dororo and vowed to kill him.
Dororo will not participate in plans that are potentially harmful to people's feelings or nature. He is extremely stubborn about it, as he desires to bring peace to Pekopon.
Even for all he has gone through, Dororo is a very kind, generous, and respectful person.
Dororo is a light blue Keronian. Throughout his childhood, he wore a medical mask, possibly due to a weak immune system. Before, he wore a white, military uniform-style hat like the other Keronians; after becoming a ninja he began wearing a white cap with shrouds in place of flaps.
The symbol on his forehead is a red, four pronged shuriken while on his chest is the same symbol but yellow. When he was an assassin, he wore a gas mask. As a ninja, Dororo dons a ninja mask and sheath for his Katana strapped to his back. Dororo's afro is light pink. Dororo is 55.5 centimeters tall (1'8 feet).

Young Zeroro, although member of a large and wealthy family, was a demure, weak, and shy child, who initially was unable to make friends at school. So, when Keroro approached him, wanting to become friends, he instantly became attached to him. Zeroro almost seemed incapable of independent thought, as he always leeched off of Keroro and Giroro. He did not like to do dangerous or forbidden things but often went alongside his friends anyway, as he was not yet stubborn and possessing strict morals like he has later.
Later on, Pururu, the class beauty, also joined their group. He was often exploited by his friends, mainly Keroro. Throughout their friendship, Keroro used Dororo for his own personal gain and was often insensitive to Dororo's feelings. Despite this, they remained close friends.
Zeroro graduated from the Keron Military Academy under the rank of lance corporal. He worked as a part of Jirara's assassin corps, the X1. Zeroro was eventually chosen as the number 1 Assassin, but that meant, according to Jirara, that he couldn't become a true Master Assassin, since the fame of that position goes against the nature of an assassin who is meant to blend into the darkness and be forgotten by all.
When the platoon landed on Pekopon and were scattered, he somehow managed to get himself caught in a bear trap. He promptly accepted his inevitable, lonely death until he was saved and taken to the ninja village by the kunoichi Koyuki Azumaya, where he learned the way of the ninja. In the anime, Zeroyasha, Koyuki's friend dog, found him in the trap.
Zeroro renamed himself Dororo after the forest he was rescued in, and rejoined the Keroro Platoon. His respect for Koyuki saving his life changed his mindset about invading and instead made him feel as if Pekopon should be respected as any other planet.
- Keroro, Giroro and Pururu - As a child, Zeroro, Keroro, and Giroro were friends. Their friendship brought them to be blood brothers (as stated by Keroro). Out of the two, Giroro was the nicest to him. Keroro took advantage of Zeroro. When he was younger, Zeroro admired Keroro when he was hardworking (according to the manga) but is disappointed at how lazy he is now. As adults, they keep their friendship in regard, but Dororo gets upset when the platoon forgets about him.
- Koyuki Azumaya - When Zeroro arrived on Pekopon, he got caught in a bear trap, and was awaiting his lonely death. He was saved by Koyuki (as well as Zeroyasha in the anime). Then Koyuki became Zeroro's partner. They stuck together during banishment (Zeroro at the time had changed his name to Dororo), and currently live together neighbor the Hinata's (the anime changed it to a small house in the woods near the Nishizawa Tower). Dororo and Koyuki hold a platonic father-daughter relationship.
- Kururu - No evidence for an actual friendship, Dororo and Kururu appear to simply be workplace proximity associates. They both admire each other's ability but disagree on values.
- Tamama - Tamama admires Dororo's strength and wisdom, and they hold a rolemodel-type relationship. Dororo wishes the best for Tamama and hopes he will grow up to be a strong soilder.
- Fuyuki - Dororo considers Fuyuki as a kind person, hopes him will stay good-hearted, and had saved him from danger more than once.
- Mutsumi Hojo - Dororo admires Mutsumi's free spirit. In the manga, they often play shogi on rooftop and cooperate in battles successfully.
Dororo uses the archaic sentence-final particle "de gozaru", a form of 'desu'. Dororo refers to himself as sessha, an archaic male form of "I", primarily used by samurai.
In general, Dororo uses 'humble' Japanese speech. Generally, one would only use this humble form when addressing superiors. Dororo takes this to the extreme and uses humble forms of speech in almost every sentence, regardless of who he is talking to.
