Unlike the spindly battle droids, whose humanoid builds allow them a degree of versatility, droidekas are designed with one sole function in mind: the complete annihilation of their targets. Slung at the end of heavy arms are immense twin blasters, which unleash destructive energy at a pounding pace. The destroyer droid can completely envelope itself in a globe of protective energy via its compact deflector shield generators, though at the expense of its mobility. Although slow and awkward on its three-legged gait, the droideka can transform into a much speedier, disk-shaped form.
Rather than use flesh-and-blood warriors, the Separatists prefer mindlessly loyal soldiers that are unquestioning of orders, and easily controlled. The soulless ranks of their battle droid armies consists of tall, thin robotic soldiers with exposed joints and bone-white or rust brown metal finishes that gives them an eerie resemblance to animated skeletons. Battle droids are very efficient, and can be controlled from centralized command centers, like the enormous Droid Control Ships used by the Trade Federation. They are dim-witted, often suffering programming glitches that give them quirky personalities that are too slow to adapt to enemies like Jedi Knights and clone troopers.
An idyllic world filled with vast green valleys and flowing waterfalls,Kiros was the site of a colony of Togruta artists, led by Governor Roshti. The artisan colony tried to avoid taking sides in the Clone Wars, but Count Dooku arrived on-planet with a droid army, and "insisted" the Togrutas accept his offer of protection. Within ten standard rotations, all 50,000 Togruta colonists had vanished.
