- "General, we've been outflanked."
- ―The droid speaking to Grievous.
A B1 battle droid was stationed on the bridge of General Grievous's Munificent-class star frigate around 21 BBY and participated in the Battle of Bothawui. During the space battle, this battle droid informed Grievous that the Separatist warships had been outflanked by Republic AT-TE walkers. The droid was then destroyed along with the rest of the Separatist fleet when the AT-TEs opened fire on the exposed sterns of the ships. However, Grievous managed to escape in his starfighter.
