Garuru Platoon

First Lieutenant Garuru: He is leader of the platoon, but unlike Keroro, he is always serious as a soldier. He is Giroro's brother, and unlike Giroro, he is the best sniper in the Keron Army, using the One-Shot-One-Kill style.

Private First Class Taruru: Tamama's 'apprentice'. During his early days he used to visit Tamama, causing trouble everytime. After he grew up, he joined Garuru's Platoon, and fought against his master, and wins, but ends up losing anyway.

Recruit Tororo: He is the hacker of the platoon, and Kururu's rival. He started computer mantainence in his early days, like Kururu. He is still immature and thinks no one is better than him. He has the same personality as Kururu, but he cannot keep cool under pressure.

Lance Corporal Zoruru: An assasin, and a rival of Dororo. The left side of his body is robotic, due to a long past feud with Dororo. His left hand can extend its thumb into a long blade for combat. He seeks revenge against Dororo, but leaves as soon as Dororo says he forgot who he was.

Chief Medic Pururu: The most recent member of the platoon, and also an expert nurse. She is the childhood friend of Keroro, Giroro and Dororo. She is energetic, down-to-earth, strict and also stubborn. But she is the most matured compared to most of the major characters.
