A Neural-Net eraser served as a protective measure against malfunctioning battle droids during the Clone Wars. For many individuals who were afraid of being targeted by Separatist droids, these devices became essential. Upon activation, the device emitted a blue energy beam that would obliterate a droid's internal components and programming, effectively disabling them.
Asajj Ventress utilized a Neural-Net eraser to target the servant droid Solis, resulting in erratic movements and loss of control.
