IG-110 lightsaber droid

The IG-110 lightsaber droid was created by the Separatists to deal with the growing involvement of the Jedi during the Clone Wars. They were based heavily on the design of the MagnaGuards, and proved effective in dealing with the lightsaber-wielding Jedi. Their programming was created from thousands of hours of holorecordings of Jedi in combat. The IG-110 would wield two lightsabers, which used synthetic lightsaber crystals.
