Final votecount:
Mr. Miyagi (3): Khan, Excel, The Dude
---
"Dude-san," Mr. Miyagi began, facing down his accusers, "I no traitor. But no can stop three of you killing me, either." A sad look came across his face. "You fight with numbers, not courage. It way of coward. This no victory for you."
The Dude, swaggering with the thrill of success, took a swig of his white russian (there probably would've been discussion about where this came from later, were it not for what soon happened). "Save it, Doctor Kamikaze, we know you're with the carpet-pissers. It's time you paid for ruining my living room!"
It wasn't The Dude that killed the aged sensei, though. An energy beam lanced out from the depths of the Watcher's keep and vaporized Miyagi's head. The Dude and Excel turned in shock to look for the shooter--and saw Khan striding out of the building, some manner of laser rifle in one hand and with something like an escape pod floating dutifully along behind him.
"While you all were bickering so amusingly, I took the liberty of...experimenting with our host's facilities. Would you guess that there are machines below capable of fabricating whatever manner of device one desires? No doubt you would not have recognized them as such, of course, lacking my keen intellect. Oh, and I should say that there WERE such machines within Uatu's keep. You would find them all thoroughly disabled were you to look now. A pity that such delightful tools as yourselves should be discarded with such abandon, but I'm afraid I simply have no further use for you. I will grant you the small mercy of each other's company as you rot slowly on the this barren world, however. I cannot let it be said that I am ungenerous towards those who serve me well, you understand."
"And now, I leave you as He left me...buried alive at the center of a dead planet."
Khan entered the craft. The door slid shut, the rocket boosters fired, and Khan's ship headed towards the stars.
As for the final survivors marooned on the moon's surface, there was only one thing they could say:
KHAAAAAAAAAAANNNNNNNN!!!!!
Mr. Miyagi (Town Cop) was lynched!
Scum win!
