Sergeant Keroro is the Captain of the Space Invasion Forces Special Advance Team of the 58th Planet of the Gamma Storm Cloud System, sent to the planet Pekopon (aka Earth) to collect intelligence for his planet's invasion force. He is also a frog. After his ship crash-lands in the planet, he takes shelter in the Hinata household, but the two kids, Fuyuki and Natsumi, find him and take away his alien weapons. When his people discover that the Pokoponians are aware of him, Keroro is abandoned - left to fend for himself in this hostile world.
