Then I guess if he faced a Light Jedi, the Light Jedi would probably lose.

But he faces a Dark Jedi who lightning bolts his ass and cuts off his head in the first ten seconds of battle, he wouldn't have time to learn anything about his opponent.

Lets go with the frist but before the whole stupid giving it up. (The T.V. HIghlander ain't band if you don't mind some discontinuity, which I don't.) Also, we might as well go all out and make it Luke with his full ablity, still straight swords because I think they are cooler then Lightsabers anyway, who wants a sword that can flicker out when it loses power. Although it would seem at one point Kyle Katarn surpasses him, from the games at least.

Edit: I'm not totally sure a chopping off the head can kill the last immortal anymore, or if it is even possible. Also, he could probably get the knowledge in less than a second.

Technically I suppose he does not actually give up immortality (like a total fucking dumbass) until the second movie.

Of course if we're going by these rules, it would seem Highlander wins no matter what -- at least as was my understanding from the first (not counting the multitude of batshit-insanery that followed under the Highlander name) the Only One who there can Be becomes all-the-way immortal, with no fear of even head-removal.

It is my understanding that Lightsabers never lose power, as they are powered by the energy of a constant fusion reaction. Or some such shit.

Who wants a metal when you can have a sword made out of lasers?

If you gave anybody a Lightsaber versus a sword, the battle would be over right there. Jedi melts McCloud's sword, then cuts his head off.

If you go all out and say Luke Skywalker, Then I would still say Luke, because his Mind Reading and Force Intuition is better trained then anyone. I would still say they are equal, becasue while McCloud has The Vortex backing him, Luke has The Force backing him. Both have an incredible force backing their actions to take on the other, and both are more skilled then any other of their kind.

EDIT: If the Last Immortal can't be killed, then why bring up this battle? And actually, he could. Just throw his ass in a Black Hole, and watch him escape it... Which will be right around never. Or throw him in the Sun.

Although, complete and utter dismemberment could be considered a Jedi victory as a torso can't really fight back.

Clearly you have not seen the third Highlander movie.

Cut him apart, burn the ends, bind them up good, bury them in seperate locals. Than he is pretty much screwed. It is a lot of work but you do what you have to.

I again refer you to the third Highlander movie, which answers the age-old question of what happens when you cut an Immortal into bits -- the bits remain capable of movement, quite able to attack, until such time as they can put themselves back together again.

I imagine it's difficult to burn the end of a severed arm when the fist is still reaching around to punch you in the face.

Yah, and in the first highlander movie, Sean Connery's character told Connor that ANY wound to any part of the body except the neck will heal immediately. The burns wouldn't stay burned. The burns would heal completely, not even leaving scar tissue in about a minute.

Its called tranq darts or just kicking the damn thing in the fire until the end burns. I never said it would be easy. I'm sure a determined Jedi could do it with the force as well. Luke would have a vary easy time of it and would realise quickly that he had to do it as he watched the pieces still fighting back.

Lightsabers are made of the force incarnate and thus is why normarl people can't weild them. You have to have significant force to activate the force crystal inside, plus I have never seen an on switch on one. If and when the force crystal goes thats the end of your Lightsaber. A good hilt shot and its toast. A well made sword, like in Highlander doesn't break or lose power.

Edit: Also their was at least one immortal that had a severed hand after becomeing immortal that did not heal. Also, when an immortal takes a good slash it takes him a good while to recover useually he either dies or goes through a quikining and the next time you seem they are healed.
