Okay, who would win? Tron understands the ins and outs of the world of electronica, seeing as how he’s, you know, a computer program.
HOWEVER…
Xena seems to be better at assessing an entire situation…including what’s going on BEHIND her, which Tron seems to lack. Also, she can distract opponents with her amazing…uhm, form.
Who would come out ahead? Or missing one? Any other characters out there who deal damage with a Dangerous Round Thingy Of If Not Death, At Least Painful Dismemberment?
Captain America has a slightly larger Dangerous Round Thingy Of Neither Death Nor Painful Dismemberment Yet Still Full Of General Coolness.
As to the question in the OP, I’m not sure. It’s a close call, but I’ve got to give the edge to Xena because of Gabrielle. Just on general principles.
You probably didn’t even see the Predator slice off all their heads with a toss of his frisbee o’ death. He was cloaked, after all.
I don’t think that Xena’s “assests” would be very useful against Tron. Tron’s a computer program. They don’t have sex, so lust is probably an unknown emotion to him. Plus, Tron can turn into a motorcycle, so he would have a serious speed advantage.
There was also this sci-fi movie with dolph Lundgren, “Come in Piece” I think it was. The bad gay had a cd that flew around slitting everyone’s throats.
Cpt. America & Xena would survive & have a love child, in my little world.
Tron was gay & obviously had the hots for his little program buddy.
The Predator guy would win in an all out death match. Only because, well… I want him to. That dude’s got tech.
Now this is why we created Cafe Society! 
B’bye.
Anyone else remember that Groundhog’s day homage episode?
Xena managed to perform about a dozen heroic deeds all by ricocheting her chakram around a city. She wins the precision award.
Cpt. America would show up, and brandish his shield. He would block Tron’s disc and Xena’s chakram, and get taken from behind by Pred.
Tron would then enter lightcycle mode, and enclose the area around Pred, and Xena would throw her chakram into the enclosure just as Tron sealed it.
There would be five minutes of screams and splashing noises while Pred learned about the law of conservation of energy.
Then Tron would ^Z, remove the walls, and bash Xena over the head before she could retrieve her chakram.
Since Tron is a compter program and his disk operates at close to the speed of light he would have to be the victor on the basis of sheer respose speed.
I seem to recall 2 cartoons featuring thrown spinning weapons. one was called “Galtar” I think and had this kid with a magic boomerang that would split into 3 little spinning parts when he threw it. the other was an animated version of Conan where one guy also had a magic boomerang that would return to him when he commanded it to. there were doubtless many other cartoons with weapons like this but none i can remember right now.
That movie was the bomb! Dolphs best (only) good movie. I think all of 5 or 6 people have seen it though. I loved that gun. It was very BOOM BOOM.
You haven’t seen the deleted scenes on the DVD, I take it? 
Where do Odd-job and his hat fit into this equation?
That and the fact that Trons disk can almost move under it’s own will.
Xena’s disk just bounces off walls and sparks…not to mention it never really hurts anyone…ok, she’s kille dpeople with it, but only dew to the impace of the thing. I’ve never seen anyone gouged open after being hit.
With Tron’s disk, they deres.
And Krull and his spinning blade thing!
And that yo-yo weapon from the video game. Star Tropics?
