A large group, specifically a battalion, of B2-series super battle droids participated in the Clone Wars, and some remained even after the end of the conflict. Sidon Ithano, a pirate, acquired the storage unit containing these super droids, alongside one B1-series battle droid, and then sold them to another pirate, Captain Kragan Gorr. Gorr utilized these droids during his failed uprising aboard the Colossus, a supertanker fuel depot. However, Neeku Vozo, a mechanic, had altered the programming of the B1 droid, giving it the simple name "B1", and designating it as the new droid leader. Due to the battle droids fighting for the crew, the Colossus crew were able to force Kragan and the rest of the Warbird gang to depart from their space station.
