Morp Droid
the design of these repulsor-equipped droids was attributed to Asajj Ventress, the Dark Jedi who was one of Count Dooku's chief lieutenants during the Clone Wars. Each morp droid resembled a floating, six-legged beetle, and delivered a powerful electric discharge when they touched living flesh. The discharge was powerful enough to electrocute a human being. Because of the incredible power used by morp droids, they seemed to glow with an electric blue aura as they sought out their targets.
