Garuru

ガルル

Garuru is an S-rank sniper, the leader of the Garuru Platoon and Giroro's older brother. He's an indigo Keronian frog with a black helmet, has a red triangle pointing downward with a line in the downword middle for his personal symbol and also wears a belt that, unlike Giroro, is kept for power instead of to remember deceased friends during a Keron war. When he heard that the Keroro Platoon had no progress in their mission and that Giroro was not the leader, the Garuru Platoon went to Pekopon to take care of the mission themselves. Garuru defeated his brother in a one-on-one gun match, but was later defeated in a rematch. Thanks to the Keroro Platoon's friendship and united power, the Garuru Platoon was defeated. It was however hinted at strongly that Garuru's true mission was merely to test the abilities of the Keroro Platoon. Garuru and his platoon appear again in episode 130, where he faces a clone of Giroro and in 154 he shows up to aid the Keroro Platoon in defeating ZZZ. It turns out Garuru is the only one who can pronounce this new menace's name without biting his tongue. In the manga he appears in volume 14, where he shocks Giroro by revealing he's there for a short holiday
