B2 super battle droid (Earth-2042)

"With these new battle droids we built for you, you'll have the finest army in the galaxy."

- Wat Tambor, to Count Dooku

B2 super battle droids, also known as super battle droids or super droids, were an advanced battle droid used by the Techno Union and later the Confederacy of Independent Systems during the Clone Wars. Super battle droids were much stronger than their predecessors, and like the updated B1s used by the Confederacy, they did not require a command system to operate, which gave the droids limited independence.
