Luke Skywalker vs Anakin Skywalker
Both Anakin and Luke are Jedi, so Anakin doesn't have any of his Sith powers(so no Force Choke). Anakin is still at his full potential and Luke is a Grand Master. It's an all out battle on Tatooine, since both grew up their. The exact place of the battle is Mos Eisley Spaceport. Both are completely healthy and have their last lightsaber as a jedi.
Who wins? 🙂
