The Cortosis B2 Super Battle Droid is a Combat Droid developed by the Techno Union and manufactured by Baktoid Combat Automata to specifically combat Jedi. They are similar to the B2 Super Battle Droid, but their outer shells are made of cortosis clamped to the droid's frame in form-fitting plates. The only weakness in their armor is a small gap between two breastplates and the photoreceptor.
