"Roger Roger"- 3B3-21, before his death

3B3-21 was an B1 battle droid that served the Trade Federation during the Invasion of Naboo. He was one of the many battle droids tasked with protecting Viceroy Gunray in the Theed Palace after it was captured by the Federation. He worked with fellow B1 unit 3B3-20 when Queen Padme Amidala and the reaming members of the Nabob Security Buru to take back Naboo for the Republic. 3B3-21 was later shot next to 3B3-20 just before the intruders escaped by destroying the nearby window and climbing up near the top of the palace.
