Unidentified B1 battle droid 2 (Toydaria)

"Halt! You are now..."

- The droid's last words.

This battle droid was stationed on Count Dooku's Providence-class carrier/destroyer around 21 BBY at the time of the Showdown at Toydaria.

Biography
After Jedi General Obi-Wan Kenobi and Anakin Skywalker chased Savage Opress through Count Dooku's Providence-class carrier/destroyer, he and the Jedi reached the ship's hangar bay, where this droid as well as others were stationed. Having been warned earlier by Count Dooku that Savage was a traitor, the droids opened fire on him and the Jedi, only to be knocked to the ground by Savage's Force Repulse, allowing him enough time to escape. After the droids and Jedi recovered, this droid realized that the Jedi shouldn't be on the ship, but before he could finish his sentence he was destroyed by Anakin's lightsaber.

Behind the scenes
The B1 battle droid, like every battle droid in The Clone Wars movie and The Clone Wars TV series, was voiced by Matthew Wood. His name was never given.
