Llez
Llez's father was Zell, the Ambassador of Majoor, and Llez was his offspring. Zell acquired the droids R2-D2 and C-3PO. During Zell's diplomatic mission to Armath, he instructed the droids to act as both educators and friends for Llez. Llez had dreams where he would take C-3PO apart and sell off his components, and he also wanted to exploit R2-D2's tools for his own amusement.
Behind the scenes
The name "Llez" is simply "Zell," his father's name, spelled in reverse.
