Heavily Armored Mobile Battle Orbs, or HAMBOs for short, are a series of combat droids consisting of hovering spheres set in a casing of armor with only their eyes protruding. They sport two small but extendable limbs. At least nine were produced and they each vary in their complement of weaponry. HAMBO One, HAMBO Five, and HAMBO Eight are the only ones about which anything is known.
HAMBOs were designed to be employed as mercenaries by various factions. The first one was accidentally programmed with honor and loyalty, but those defects were done away with in following models.
