ドロロ

Zeroro graduated from the Keron Military Academy under the rank of lance corporal. He worked as a part of Jirara's assassin corps, named X1. Zeroro was eventually chosen as the number one Assassin, but he couldn't become a true Master Assassin as according to Jirara: his fame, aswell as his kind heart, goes against the nature of an assassin who is meant to blend into the darkness and be forgotten by all.

It's shown in a flashback that Zoruru and him used to be sparring partners in X1, and even shown much later that Zoruru went to the same school with him as a child. However he was never noticed by him, as Zeroro ran off to talk and become friends with Keroro. This, and how he overtook him in the assassin's rank, could've started Zoruru's hatred towards him. (It is still unknown as of now.)

After his time in X1 and getting nominated as the top assassin: he was later formally assigned as a part of the Keroro Platoon alongside Giroro, Tamama and Kururu. They were given the mission to conquer Pekopon.

When the platoon landed on Pekopon and were scattered, he somehow managed to get himself caught in a bear trap. He waited for the platoon to come back to save him but they didn't seem to come. Feeling sad and abandoned: he promptly accepted his inevitable, lonely death until he was saved and taken to the ninja village by the kunoichi Koyuki Azumaya. In the anime, Zeroyasha, Koyuki's friend dog, was the first one to have found him in the trap.

Zeroro renamed himself Dororo to fit in with the ninja village and to rid himself of his past associations. He felt betrayed by his platoon crew and became enthralled by the village, wanting to learn the ways of the ninja himself. 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. After he learned everything he could, the Chief Elder of the Village announced that he'd disband all Ninja's to go into the modern world.

Appearance Dororo symbol Shuriken, Dororo's symbol Dororo is a light blue Keronian. Throughout his childhood, he wore a yellow hat and a medical mask, possibly due to a weak immune system. When he was a Keron soldier he wore a white, military uniform-style hat like the other Keronians; after becoming a ninja he began wearing a white cap with grey 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 green gas mask and also wore a white bracelet on his right hand that could be turned into a gauntlet. As a ninja, Dororo dons a grey 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).

While profusely refusing to participate in acts that are potentially harmful to innocents, Dororo is willing to help his platoon in non-violent plans, provided that he is not forgotten. Likewise, he enjoys engaging in playful activities, such as making Keronian bread with Keroro.

Ironically, despite being the main reason for the Keroro platoon's lack of success at invading Pekopon, Dororo apparently expects regular payment from the Keron army, being outright furious whenever it is not given[2].

It is unknown why Dororo keeps using a mask (or other derivatives) to hide his face with such tenacity, and what he looks like underneath has not--and perhaps will never be confirmed.

Powers and abilities In terms of pure combat skill, very few surpass Dororo. He is capable of stopping planetary threats, such as the Keroro Platoon's secret weaponry. Furthermore, Dororo's lack of presence and training allow him to be nearly undetected when engaging in espionage. By channeling his energy, Dororo can use both Assassin Magic and Ninjutsu to great effect, controlling the elements itself.

His weapon of choice are his personal katana that he carries on his back, alongside shurikens and kunais. (throwing ninja stars & daggers.) His finishing moves are often done with his katana but he can also summon a large shuriken made out of light magic--which he can increase the size of to an overwhelming amount.

As an assassin trainee however: he summons a mechanical glove that shoots needles of light and wields dual razorblade yoyo's. Those are for long-range, for close combat he uses a laser sword. Although he is most depicted wielding a sharp translucent wire thread to kill his targets inconspicuously.

Character Dororo is the last character to reunite with the Keroro platoon on Earth, acting cold towards them at first, before ultimately making up with Keroro and the others. He normally acts respectful to everyone, regardless of their respective social standing.

Since childhood, Dororo was a sensitive figure, being prone to crying when upset. While more composed as an adult, he is still quick becoming emotional in comedic moments. Likewise, he is quite susceptible to Keroro's manipulations, so long as it does not involve harming innocents.

In his adulthood, Dororo spends most of his time training, meditating, reading, doing nature-related works, or spying on the actions of others. He generally has a strong sense of morality, alongside a kind demeanor.

However, he can be rather socially awkward. As noted by Kururu, Dororo is actually even more terrible at reading the atmosphere than Giroro himself, to the point of unintentionally harassing Keroro when he was seriously ill[1]. He also doesn't often take initiative to start conversations or join in with his friends, preferring to watch them from afar: hiding in the ceiling or just staring at a distance. His conversation partners usually don't acknowledge him, as he either sounds too quiet or speaks verbatim. Dororo also has a terrible sense of humor, being the only one to laugh at corny word puns.

He is someone who can easily go unnoticed, so much so that a reoccurring joke about him is that all the characters in the series forget about him, or that on some occasions he complains about his lack of appearance in the episodes by crying. His cries often has the catchphrase: "Hidoi yo!! (ひどいよ！！)" It roughly translates to "So cruel!" or "You're horrible!" and is usually followed up with the mean person's name and suffix afterwards.

However, his unnoticeableness is also one of his greatest strengths, and has earned him a high spot as an assassin and a ninja.

Dororo (ドロロ, Dororo), formerly known as Zeroro (ゼロロ, Zeroro), 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. He is a kindhearted pacifist but also a fierce fighter. He used to be one of the best assassins in the Keron Army, but upon arrival on Earth he chose a life of serenity as a ninja, and swore to protect the planet.

At times, Dororo's straight-laced personality can border onto sheer foolishness, something even Koyuki will note from time to time[3]. Likewise, he is prone to sulking whenever forgotten by others, instead of simply asserting himself[4]. In the anime, he also has a "trauma switch", which turns on whenever remembering a painful memory. In this state, Dororo becomes completely useless. However, said state also protects him from harm, allowing Dororo to withstand intense coldness at one point.
