Garuru

ガルル

Garuru is an S-rank sniper, the leader of the Garuru Platoon, and Giroro's older brother. He is an indigo Keronian frog wearing a black helmet. His personal symbol is a red triangle pointing downward with a line in the middle, and he wears a belt that, unlike Giroro's, is kept for power rather than to remember deceased friends from a Keron war. Upon hearing that the Keroro Platoon had made no progress on their mission and that Giroro was not the leader, the Garuru Platoon traveled to Pekopon to handle 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. However, it was strongly hinted that Garuru's true mission was merely to test the abilities of the Keroro Platoon. Garuru and his platoon reappear in episode 130, where he faces a clone of Giroro, and in episode 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 is there for a short holiday. He brings a gift to Giroro, which grows into a large, flying sweet potato, and the brothers have to team up to bring it down, a ploy by their father to teach them a lesson. In the end, Powered Natsumi shows up, helping Garuru defeat the potato with her beam sabres, as it is immune to guns and other ballistic weapons, and Garuru appears impressed by the girl. During the fight with the potato, there is a flashback from Giroro and Keroro's childhood, showing a younger, presumably teenage Garuru defending his younger brother and friend against two bullies intending to take over their secret base/playground. Another interesting detail is that the younger Garuru wears the same kind of belt as present-day Giroro, with a rectangular buckle. In volume 15, he sends Pururu to investigate the Keroro Platoon regarding their desire to invade.
