Unidentified B1 battle droid 17

"Look, Jedi!" "Fire!" "No, wait...I knew that was a bad idea."

- A fellow droid speaking to this one.

A B1 battle droid was stationed on the Separatist Subjugator-class heavy cruiser, the Malevolence, and served under command of General Grievous.

History
Around 21 BBY, after the Malevolence suffered a defeat at the Battle of the Kaliida Nebula, the Separatist forces captured Naboo senator Padmé Amidala and brought her aboard the warship in order to force the Galactic Republic ships to stop their attack. The senator eventually managed to escape and this droid was part of a squad tasked with finding her.

Later, this droid and two other came across Jedi knight Anakin Skywalker and Jedi Master Obi-Wan Kenobi, who came to the warship to save Amidala. Despite what another droid said, this one opened fire on the Jedi, who managed to deflect the shots back with their lightsabers, hitting this droid and a fellow one.
