3B3-888 was a Trade Federation B1 battle droid who served in the Droid Army of Viceroy Nute Gunray. When Gunray's forces invaded and occupied the planet Naboo in 32 BBY, the native Gungans responded by massing their own army to combat the invaders. 3B3-888 was a part of the force dispatched to eliminate the Gungans, and the droid captured two enemy officers during the resulting battle. 3B3-888 was later deactivated, like all other Federation droids on the planet, when the Droid Control Ship orbiting Naboo was destroyed.
