D-O in the fantasy universe of Star Wars is a droid created by a droidsmith Babu Frik from different parts. This hot-tempered droid was reactivated by BB-8 in 35 ABY on Pasaana and then taken to Kijimi, where it was repaired. Little D-O befriended the Resistance droid and wanted to be like his droid friend in every way. By the way, D-O can speak a less complex form of droid binary as well as a basic language, although it is rather limited and often garbled. The Star Wars D-O cursor for a mouse!
