Beetle Drones

Beetle These are Beetle like robots that make up the standard infantry of Aku's minions after the X-Models. They crawl on land like actual insects but when they are in battle mode, they stand up on two legs. They could travel in great speed on both land and air. They were armed with four powerful scythes attached to their body. Though affective opponents, they were no match for the skills of Samurai Jack. Later they were upgraded with insect-like wings on their back which allowed them to fly. In their first major appearance, Jack had recently arrived to the future and managed to destroy the drones sent by Aku after formulating a plan to protect the canine archaeologists. After this battle, the Beetle Drones made minor appearances throughout the rest of the series.

Though they are robots, they seem to be able to feel fright, which can be seen when at least one beetle drone attempted to retreat during a battle.
