E-10 was a protocol droid owned by the wealthy Human heir Dezono Qua, with whom the droid lived on the planet Esseles. Under orders from Qua, E-10 prepared and cooked a number of young slaves that its master had purchased and wished to eat. After E-10 cooked the Nosaurian child Resa Greenbark, the droid's master congratulated it on the quality of the dish. The meal proved to be the last the droid prepared, however. Shortly after the dish was created, Resa's father, Bomo Greenbark, arrived at Qua's home and destroyed E-10 after it refused to tell him of Resa's fate.
