R2-F2

R2-F2, also known as Eftoo, was the personal astromech droid of Zakon Vlanc.

Jedi Praxeum
Shortly after its creation, the Jedi Praxeum purchased hundreds of astromech droids, R2 included. R2 first acted as a technician, repairing the numerous star ships and other droids. However, he was later reassigned to be the personal astromech droid to Zakon Vlanc, son of an Imperial Moff. R2 disliked Zakon's sister's astromech droid, R2-E7, because Eseven believed himself to be superior to other astromech droid, and because he believed that Eftoo was not good enough to serve as Zakon's astromech droid.
