Once Supreme Commander of the Grand Star, Obaba is a female Keronian seen tending to a Keronian garden that used Pekoponian Architecture that was laid with traps, to test Keroro and the others. Its hinted she was the one to refer the headquarters of Keron to to Volunteer the Keroro Platoon for the Pekopon Invasion. She is friends with Keroro's Mother. She also owns a Andromedian Small Breed, which appears to like Obaba very much.
Obaba's name comes from the Japanese word obaasan/ oba-chan meaning grandma or old lady.
Obaba's name also seems to be close to the name of United States President Barack Obama. His catch phrase "Yes we can" was also used in this episode.
