Kit Fisto, the Nautolan Jedi Master, wielded a lightsaber with a green blade. This weapon was used by Kit Fisto throughout the Clone Wars as he fought against the Confederacy of Independent Systems. His lightsaber was uniquely altered by Fisto; he implemented two crystals that were powered by a split ignition pulse, creating two currents. This unique build allowed the lightsaber to function perfectly even when completely underwater. This alteration proved very useful when he was stationed at the water-heavy battle zones of Kamino and Mon Cala.
