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. The bronzen-armored combat automata has a frightening build, insectoid in its mix of curves and sharp angles. 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.
Although slow and awkward on its three-legged gait, the droideka can transform into a much speedier shape. By curling into itself, the droideka can turn into a disk-shaped form, which can roll on smooth surfaces at impressive speeds.
The Trade Federation uses droidekas aboard its starships for security, as well as on ground during combat operations.
