The lightsaber of Agen Kolar, the Zabrak Jedi Master, was unique because it contained two kyber crystals. This allowed the plasma blade to emit either a green or blue color. The second crystal originated from the lightsaber of his Padawan, Tan Yuster, who met his death during the First Battle of Geonosis. He used this weapon when he died during his duel with Darth Sidious, along with Saesee Tiin, Kit Fisto, and Mace Windu. Its design seemed to mirror Adi Gallia's second lightsaber.
