Lucien is a strong fighter who can use the Force as well as his lightsaber. He won’t be going down to Sasuke very easily…but he will be going down all the same. Sasuke’s Chidori sword can hold its own with a lightsaber and moreover he has the definitive edge in combat ability. His speed and power are far greater than anything Lucien has seen in his day. He would be getting completely overwhelmed in the end. Sasuke wins.
