Dororo

Height: 55.5cm

Lance Corporal Dororo (Formerly known as Zeroro) is the Keroro Platoon's assassin who crash landed on Pekopon and was forgotten about by his platoonmates (as usual.).

Soon after, he found his leg caught in a bear trap and awaited his lonely death, until he was rescued by female ninja Koyuki Azumaya (With the help of Zeroyasha, the dog, in the anime). He decided to follow the way of the ninja, he changed his name to Dororo, the name of the forest where Koyuki rescued him.

Dororo is often forgotten about by the rest of the platoon and most everyone else but Koyuki, which will cause his Trauma Switch to turn on. When this happens, a purple, gloomy era radiates from Dororo and he will sit in a corner or dark space and cry. His Trauma switch is usually activated when he is reminded of something done to him by Keroro during thier childhood, Such as using him as a sheild in a snowball fight caused him to remember when he was used in the same way during a dodgeball game.

Dororo has a love for all creatures and nature of Pekopon. He has stated that he has "fallen deeply in love" with the planet. As a result, he will not participate in plans that will potentially harm people's feeling or nature, or endanger any wildlife species on the planet. Dororo has vowed to protect Pekopon at all costs along with Koyuki.

Dororo used his natural quietness and ability to be unoticed in the form of stealth after inspired (ironically) by Keroro to become an assassin in the Keronian Military. He joined an elite group of assassins along with Zoruru, led by Jirara, before departing for Pekopon as a Lance Corporal (In the manga, formerly a Private Second Class).

Dororo often ends his speech with "De Gozaru", an archaic form of "Desu". Also, Dororo adressed himself as "Sessha", an archaic male form of "I" primarily used by Samurai. Early in the series, one of Dororo's more common actions was to speak to Keroro and the others in the form of a shuriken made of paper which acted as a note, when needed. The shuriken would always seem to stick itself in Keroro's head, usually causing him to freak out until it's removed by another platoonmate. Dororo does not need to be close by to perform this.
