B1-0516

"You're ready to switch sides, are you?" "You bet! Battle droid B1-0516 at your service."

- Obi-Wan Kenobi and B1-0516

B1-0516, nicknamed Bats, was a B1 battle droid in the droid army of the Confederacy of Independent Systems. During the Clone Wars, B1-0516 fought in a battle against the Galactic Republic on Horain, where his processor was short-circuited by a stray blaster bolt. The damage caused B1-0516 to fight with the Republic army, and he assisted General Obi-Wan Kenobi and Captain Rex, who gave the battle droid a nickname.
