Mitsurugi's prowess as a swordsman was phenomenal, even by Darth Vader's standards, and was known to fight with a lightsaber-resilient blade made of an unidentified metal.
Mitsurugi was originally a character from the Soulcalibur series of video games, in which he is identified as a Japanese samurai.
