As a combatant droid in the Cauldron located on Rattatak, Mantoid was a droid gladiator. Its construction consisted of a dark-colored chassis and eight appendages, each equipped with a unique close-quarters weapon, such as blasters, bladed instruments, and a spiked club. Its circular, flattened head was designed with optical sensors placed around the edge, allowing for complete 360-degree vision to prevent adversaries from approaching undetected. However, during a close-range battle inside the Cauldron, it met its demise at the hands of Grunda Dolma.
