Updated battle droid

This battle droid was an advanced type of class four droid battle droid that was designed in an intent to replace the B1-series battle droid in the Droid Army of the Confederacy of Independent Systems in 20 BBY. It was biped humanoid in shape and described as an unstoppable killing machine.

When the Grand Army learned of its existence, they launched an attack on the factory. The battle droid army shot all the clone troopers and brought the plans, within a data chip, back to the Confederacy at a Separatist asteroid base. They had not made extra copies as the risk was too dangerous. Upon hearing that the B1-series battle droids were to be outdated once the updated battle droid was to be produced, the B1 which brought it back fired on the console, destroying the plans so its platoon brothers would not be scrapped.
