About Dororo

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. 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.

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.
