Aga were large, semi-sentient beings with six legs hailing from the planet Zelos II. Aga were pack creatures, and they would attack other creatures not only for food but also for the sheer enjoyment of the fight. They were known to use simple tools such as clubs, which showed their potential to become an advanced species. During the Galactic Civil War, Emperor Palpatine was known to have drugged them and used them as guards.
