Ground rules: I haven’t read all the Star Wars books, so I don’t know what future training Luke receives. I’m going with the Luke Skywalker circa Return of the Jedi. If I’m allowing Luke a lightsaber, and I am, I figure I should give the Chief the Covenant energy sword, the assault rifle and grenades. The arena is the Halo level Blood Gulch with Luke starting at the Blue Base with a sand speeder for the vehicle. Master Chief spawns at the Red Base with a Ghost.

Personal Bias: I was really into the first Halo, less into Halo 2, and only played Halo 3 once. Star Wars episodes IV through VI are awesome (see top movies list) The Revenge of the Sith was okay.

Fight! The Master Chief starts off wandering the base making sure there are no other weapons to be collected. There aren’t. He puts up the sword opting for the rifle and boards the Ghost, heading for the center of the map. He finds no one. He proceeds to the Blue Base to discover the speeder is gone. The Chief patrols around the perimeter of the map and spies Luke dismounting the speeder and taking off on foot into the caves. The Master Chief opens fire.

Luke hears the buzz of the Ghost and activates his lightsaber. With four defensive swings he deflects the laser blasts of the Ghost, returning them to the sender. The Ghost takes critical damage and Master Chief leaps off the vehicle taking damage to his shields. He rolls in a crouching position, rife drawn. Luke is already inside the caves.

Master Chief boards the deserted speeder, refusing to play Luke’s game. He zooms to the other only other exit from the cave and dismounts. Drawing the energy sword, he makes his way through the cave.
Out of no where Luke pounces from the dark corner and sword and saber connect. The blow knocks the blade out of Master Chief’s hand. The Chief takes a swing at Luke, narrowly missing him and hitting the stone wall above. The force of the blow is so powerful that the wall collapses. Fragments of stone come down, crushing the light saber, and dust fills the air. Master Chief can barely see when a boulder flies into his helmet. Stones come from all directions as Luke commands the force. Master Chief’s shields go down, but not before he lights the room with artillery fire. Unable to deflect the bullets, Luke finds cover further down the cave. He spies the energy sword.

Click click goes the rifle when the Chief pauses to reload. That’s when he sees the dust reflect the blue light of his coming demise and Luke drive the Covenant energy sword through the Chief’s armor.

Results: Luke Skywalker is victorious with minimal injuries from the wall collapse and in the market for a new light saber.
